Craig Perciavalle, president of Austal USA

ElectraWatch, Inc., a privately-held company headquartered in Charlottesville, Virginia, was purchased by Mobile, Alabama-based Austal USA. The acquisition extends Austal USA’s ability to support the U.S. Navy fleet where nearly every ship includes aluminum structures.

“The combination of ElectraWatch patented technology along with Austal USA’s advanced ship manufacturing and sustainment expertise reinforces the company’s position as an industry leader to efficiently support the aggressive shipbuilding and sustainment requirements from our U.S. Navy customer,” said Craig Perciavalle, president of Austal USA. “As innovative technology reaches deeper into shipbuilding construction and sustainment, we remain laser focused at providing cost-effective solutions to our customers.”

Utilizing an electrochemical methodology, ElectraWatch engineers replicated laboratory testing measurements within a portable DoS Probe that yields a fast, accurate, measured result without removing test samples from a ship and sending to a laboratory. The company supports multiple shipbuilders, maintenance providers and the U.S. Navy across a broad range of military ships currently deployed in the U.S. fleet.

As both the designer and prime contractor, Austal USA manufactures the Independence-variant Littoral Combat Ship (LCS) and Expeditionary Fast Transport (EPF) for the U.S. Navy. The company delivers two LCS and two EPF per year with the capacity to increase its manufacturing rate at its 166-acre facility and headquarters in Mobile. Eight LCS (even numbered LCS 2 through 16) and nine EPFs (T-EPF 1-9) have been delivered to date. Austal USA was also one of five prime contractors awarded a concept design contract for the U.S. Navy’s future guided missile Frigate (FFG(X)) while its EPF is also being considered to support permanent medical ship operations.

Special Steel Plant in Kapfenberg, Austria, to Boast Fully Automated Melting System

 

Franz Rotter, head of the High Performance Metals Division

Since the official groundbreaking ceremony in April 2018, preparations for the construction of the world’s most advanced special steel plant in Kapfenberg, Austria, have been progressing rapidly. By awarding the contract for the electric arc furnace, the converter, and the secondary metallurgical systems—which represent the technological core of the plant—voestalpine has taken another important step in realizing the project.

The SMS group, based in Düsseldorf, Germany, will be responsible for the engineering, process technology, and start-up of the fully automated melting system, which will begin production in 2021.

“Awarding the contract for the supply of the main melting units, which represent around one-third of the total investment volume, lays the technological basis for the new special steel plant,” said Franz Rotter, member of the management board of voestalpine AG and head of the High Performance Metals Division. “The SMS group will contribute its comprehensive know-how to this project, both in the metallurgical systems and in the areas of digitalization and automation.”

In addition to the electric arc furnace, in which ultra-pure scrap and alloys are melted into liquid special steels at temperatures of up to 16232°F (9,000°C), the SMS group will also supply various after treatment systems that give the material its special properties. The units are operated with electricity from 100 percent renewable energy.”

The plant technology will set new standards worldwide in terms of digitalization. An ultra-modern sensor and electronic system enables the entire production process to be controlled from a central control station.

Selecting the Right Vacuum Pump Oil Starts with Knowing Your Pump

Vacuum furnace heat treaters know that one of the most critical parts of their system is the pump oil, but it may be a bit overwhelming trying to determine which is the right kind of oil is needed. Selecting the correct vacuum pump oil starts with knowing your pump.

“‘Oil’ is a bit of a misnomer because modern pump oil technology has evolved well beyond the original distilled petroleum products. There are now double- and triple-distilled oils available, as well as hydro-treated oils, low sulfur oils, silicone-based synthetic oils, and flushing oils used to clean the pump. Due to the wide variety of formulations available, these are often now referred to as pump ‘fluids’ rather than pump ‘oils’.” — VAC AERO International

“Different pump oil formulations are specifically designed for different pumps and different vacuum applications,” notes VAC AERO, and a key factor in learning how to select the correct pump oil is the understanding of vapor pressure, viscosity, and distillation methods, as well as solvent refining, hydrotreating, synthetic oil (Perfluoropolyether), flushing oil for vacuum pumps, and diffusion pump oils.

Dan Kay on Brazing Stop-Off Materials

Heat Treat Today will soon be launching Heat Treat Consultants, a resource that offers the most comprehensive listing of heat treat industry consultants. An example of the type of exchange we anticipate will result from this resource is provided below.  Click the link above for a sneak peek at our inaugural list of consultants and more information about contacting one of the experts listed. 
 [spacer color=”848484″ icon=”Select a Icon”]

Mike Dascoli, general manager of County Heat Treat in Millbury, Massachusetts, asked our publisher, Doug Glenn, about a product the company had used previously, “an alumina oxide powder to coat graphite fixturing plates . . . in our vacuum furnaces to stop off against braze alloy run off and eutectic melting.” Doug queried whether it was aluminum brazing or more conventional brazing of stainless or other metals and Mike specified, “No aluminum brazing . . .  used to be gold/nickel, silver alloys. Here at County, I am just looking to introduce some options. I remember we would mix the powder with the acetone and paint it on the carbon plates. Acetone evaporated quick and the powder was left behind. For us now, it’s more about a layer against eutectics when heat treating.”

Dan Kay, Kay & Associates Brazing Consulting &Training Services

Doug brought in one of Heat Treat Today‘s consultants, Dan Kay of Kay & Associates Brazing Consulting & Training Services, to assist in hunting down the answer to Mike’s question.

Dan Kay:

Hi Mike —

Yes, there are a number of brazing filler metal (BFM) manufacturers who also produce and supply brazing stop-off materials that can be painted onto graphite surfaces such as you mention in your note to Doug Glenn.  Here are just a few:  Surface Flow Technologies (Div. of LSN Diffusion Int’l) in Michigan, Wall Colmonoy Corp in Michigan, Vitta Corp in Connecticut, and Wesgo Metals (Div. of Morgan Advanced Materials) in California are some of the primary ones.  

Stop-off materials come in different colors, the coloring of them being merely to identify its manufacturer, since all stop-off materials use metallic oxide materials to create their “stop-off” capabilities, and all these oxide powders are essentially white, to begin with.  Thus, to differentiate the various stop-offs they began to color them so that people would learn to associate green stop-off with company A, pink stop-off with company B, red stop-off with company C, etc.

White stop-off products are essentially the weakest of all the colored stop-offs out there and are primarily aluminum-oxide products in a paint-like consistency.  The binders/gels used to make the stop-offs vary considerably from manufacturer to manufacturer are proprietary, and you’ll not get any of them to actually tell you about all the ingredients in them.  People are often surprised to hear that a product such as Phillips Milk of Magnesia, available in lots of stores or pharmacies, is actually a decent stop off (magnesium oxide) for a number of applications.

But you are correct to say that you can make your own in many different ways by merely mixing some aluminum-oxide powder, or titanium-oxide powder, etc., in with a variety of quick-drying solvents, perhaps also with a thin acrylic type cement to give it adherence, paint it onto graphite surfaces, and after evaporation you would be left with an adherent layer of that protective oxide barrier, so that it prevents direct contact of a metal (especially any iron-containing metals) with the graphite, since an iron-carbon reaction is to be avoided.  

I’d be happy to assist you further with this, if you have additional questions, since I’ve had much direct manufacturing experience over my 45+years in the brazing world, a lot of it involved in making BFMs, brazing stop-offs and cements, etc., and am pretty much aware of the companies today who make and supply such materials.

On my website at http://www.kaybrazing.com, you will see a tab on the homepage that shows “Brazing Suppliers”. By clicking on that tab you can see a listing of the different companies who produce these materials, and in that tabular section the name of each company (such as those I mentioned above) is a hotlink that will bring you directly to that company’s website so that you can search it for a specific type of product that you might desire.  It part’s of the service that I want to provide to users of my website.  I hope you will find it useful.

Let me know how I can help you further.

Best regards,
Dan

High-tech Heat Treatment Facility Launched in Russia

A leading global iron ore and HBI producer and supplier, as well as a producer of high-quality steel, recently launched heat treatment systems with advanced technology for a Russian steelmaking and metal rolling company.

Andrey Varichev, CEO, Management Company Metalloinvest

Metalloinvest, based in Moscow, installed the Roller Hearth Heat Treatment Furnace #1 and Rolling Quenching Machine #1 at Ural Steel. Mosgipromez provided the design and engineering work for the new facility, while Tenova LOI Thermprocess was responsible for equipment delivery.

The installation of Roller Hearth Heat Treatment Furnace #1 and Rolling Quenching Machine #1 at Sheet Rolling Facility #1 enables Ural Steel to increase the production capacity of the heat treatment furnace from 28.6 to 30.7 tonnes per hour. Over the next 10 years, between 2019-2028, Ural Steel will be able to increase the production of heat-treated heavy plate by three times, and the output of steel for bridge construction by 39%. Production volumes will increase due to the introduction of a new product variety, which will be developed at the heat treatment facility.

Roller Hearth Heat Treatment Furnace #1 and Rolling Quenching Machine #1 will also help to improve the characteristics of the heavy plate, ensuring the physical uniformity of the rolled steel products following heat treatment, by improving heating and cooling conditions.

“The project has been completed as part of Metalloinvest’s comprehensive investment programme to reorganize production processes at Ural Steel, which will boost the operational and management efficiency of the enterprise,” said Andrey Varichev, CEO, Management Company Metalloinvest. “This new high-tech facility will strengthen the Company’s position in the market for heat-treated rolled products.”

Andrea Lovato, CEO, Tenova

“Metalloinvest is a special client for Tenova, to whom we supply our full range of products and technological solutions,” said Andrea Lovato, CEO, Tenova. “Taking part in the reorganization and modernization of Ural Steel’s production processes is a great opportunity for us, and we are confident that our partnership with Metalloinvest will help the enterprise to progress its development even further.”

This project follows Metalloinvest’s recent agreement to build a heat treatment facility for hot-rolled steel at the OEMK’s finishing plant #2, which will include the construction of a building for the heat-treatment facility and two thermal furnaces, and the creation of heavy-lifting and transmission equipment, as well as associated infrastructure. The first furnace is planned to be launched in 2019, and the second will begin operations in 2020.

The new facility will enable OEMK to carry out various kinds of heat treatment from 750-1800°F (400-980°C), a wide range of temperatures, in order to produce high-quality rolled steel products with a specific microstructure. Heat treatment is required in the production of various kinds of steel for springs, ball and roller bearings and construction, as well as for high-strength metal.

Varichev said: “We are seeing a high level of demand among customers for high-quality bars, which require heat treatment. Creating this new production facility will enable Metalloinvest to increase sales volume of this premium product and reinforce its position on the SBQ market.”

Heat treating thermocouples are thermal processing sensors that allow equipment operators to accurately measure and maintain the right temperatures for softening, hardening, and material modification. A faulty thermocouple can result in inaccurate measurements, so it’s critical for quality management personnel to determine when and why thermocouple failure has occurred. GeoCorp, Inc., has provided a series of short articles that walk operators through assessment and troubleshooting of thermocouples that go bad.

Sometimes the smallest issues can lead to big problems. When your business relies on crucial temperature readings from your thermocouples, it can pay to pay identify individual factors that may have cause part failure. ~ James LaFollette, GeoCorp, Inc.

When troubleshooting thermocouple failure, the authors, James LaFollette and John Ochenas, recommend reviewing three key issues: system wiring, probes, and wire and junction. In addition, the following could cause misreadings:

  • metal fatigue
  • oxidation
  • contamination
  • poor installation

How to Know Which Softening Process to Use in Your Heat Treatment

 

 

Source: Metlab Heat Treat

 

When steel needs to be softened to alter ductility, toughness, or properties, or to produce a specific microstructure, a heat treater can turn to any one or combination of processes to suit the material or the application.

Metlab Heat Treat’s primer series includes a short explanation of the options available, whether it is

  • annealing, which “removes the internal stresses, which build up as a result of cold working and other fabrication processes;”
  • protective atmosphere normalizing, which “refines the grain size and enhances the uniformity of the microstructure;” or
  • spheroidize annealing, which “is generally done on parts which have been work hardened, to allow them to be further worked, either rolled in the case of coils, or drawn for wire.”
