An industrial automation manufacturer has ordered a heat treatment system to establish a captive hardening plant within their machine park. The line of two vacuum furnaces, an atmosphere furnace, and a washer will harden and carburize parts, specifically gears, pinions, and shafts.

SECO/WARWICK , a manufacturer with North American  locations, will produce the furnaces to harden and vacuum carburize the elements used in motor reducer production. These parts figure in the automation applications production process for industries such as automotive, aviation, food and printing.  

“In these times of constant problems with maintaining the supply chain, having captive heat treatment within a machine park provides our partners with a huge competitive advantage and independence," says Maciej Korecki, vice president of the Vacuum Furnaces Segment at SECO/WARWICK Group. "Within a relatively small area, we can create a heat treatment system that will meet the Partner’s needs."

Two large H13 extrusion dies for two separate companies were vacuum heat treated in a high pressure gas quench vacuum furnace that fully hardened the dies in successive cycles.

Solar Atmospheres, using a furnace from Solar Manufacturing, provided two Ohio companies as-quenched dies with hardness of HRC 50-52 using nitrogen as the quench gas. The hollow die was 30” outer diameter x 15” inner diameter x 103” long and weighed 16,000 pounds. The solid die, belonging to a different customer, was 34” outer diameter x 64” long and weighed 14,000 pounds. Post-quench each component was triple air tempered resulting in a final hardness of HRC 46-48.

The 10-bar 600 HP high pressure vacuum furnace permits the company to obtain the desired cooling rates, commented Mike Johnson, director of sales at Solar Atmospheres.

HTD Size-PR LogoAn electric vehicle manufacturer will move the heat treatment of their prototype gears in-house with a vacuum furnace. The company expects new product development to accelerate.

SECO/VACUUM, a SECO/WARWICK Group company, will deliver a CaseMaster Evolution (CMe) model with a working hot zone of 16”x16”x24” and a load capacity of 440 lb. The EV maker’s R&D lab will use furnace to low-pressure carburize and oil quench prototype gears. With this expansion, the manufacturer hopes to mitigate scheduling delays encountered when sending their prototype gears out to local commercial heat treatment shops.

“We have a strong partnership together," said Peter Zawistowski, managing director of SECO/VACUUM, "having commissioned a number of highly successful heat treat furnaces that provide a wide variety of processes in their plants across the world."

Heat Treater Expands with Vacuum Furnace

/ BRAZING NEWS, FEATURED NEWS, MANUFACTURING HEAT TREAT, VACUUM FURNACES NEWS

HTD Size-PR LogoA Swiss commercial heat treater ordered a vacuum furnace. A system will increase the production capacity of their nickel and silver brazing processes.

The SECO/WARWICK vacuum furnace helps with hardening larger size parts and significantly increases the efficiency of the current hardening plant. The furnace increases production. In the version ordered by the Swiss, a large working zone (36"X36"X48") with the potential to adjust to an oversized load utilizes the advantages of a round heating chamber.

“[With a] cooling capacity of 15 bar, it is possible to process parts that require very fast cooling . . . . Vector also allows the system to perform more difficult brazing processes with either nickel or silver," explains Maciej Korecki, vice president of the Vacuum Furnace Segment, at SECO/WARWICK Group. "This is our second installation with this partner. Previously, we delivered a solution from the SECO/WARWICK furnace family of a similar size, in a non-pressurized version."

Ceramic matrix parts materialize when nanofibers of silicon carbide or other ceramic nano threads are wound together, forming various sheets and 3D-printed shapes. The nano threads in the process are coated with proprietary resins that must be completely removed from the substructure using heat. The resulting finished product is lighter and stronger than titanium.

L&L Special Furnace Company, Inc.'s Model XLC3672 has a work zone of 32” wide by 32” high by 66” deep. It has a single zone of control with a temperature gradient of ±20°F at 1,100°F using four zones of temperature control with biasing to balance any temperature gradients. The Model XLC3672 is controlled by a Eurotherm Nanodac Mini 8 program mechanism with overtemperature protection.

The Andritz Group, a manufacturer of complete lines for cold-rolled strip production and processing, has ordered a vertical vacuum furnace. The furnace for gas quenching processes will help produce consistent product quality.

SECO/WARWICK Group , a manufacturer with North American  locations, equipped the Vector® furnace with a graphite chamber, gas cooling system, and a rotating hearth. The Andritz Group, with this system, adds to their heat treat capabilities in hydraulic power, pulp, and paper as well as metals processing industries.

This is the first vacuum furnace manufactured in the Tianjin facility of the SECO/WARWICK Group. “We have already worked with the Andritz Group, but this time it is the first contract with our Chinese branch. The Vector furnace is manufactured in our Chinese factory, which significantly shortens the solution’s delivery time to the customer," says Maciej Korecki, vice president of the Vacuum Products Segment at SECO/WARWICK Group.

RIDGID® TOOLS received twin furnace systems from a North American supplier. These systems will heat parts from ambient to 975°F, soak for two hours, cool to 120°F, soak two hours, and then repeat. This will increase the production capacity of the company's current operations. 

The furnaces, from DELTA H®, feature a stainless steel interior with low mass ceramic fiber insulation for minimal heat retention, are designed to receive baskets with parts from an Ipsen Titan vacuum furnace, and include a floor guide system to enable precise load placement.

"We had a challenge with utilization of our [current] vacuum furnace where a secondary heat treatment might be better accomplished with a convection furnace," explained Nicolas (Nic) Willis, metallurgist/heat treat manager at Emerson Professional Tools, provider of RIDGID® TOOLS. "This would dramatically increase the production capacity of our vacuum furnace and fully [optimize] this process. The extreme and demanding rapid heating and cooling cycles called for a unique convection furnace design."  

"I have known Nic for many years, including the Cleveland Chapter of ASM International where we both served as officers – and was honored to nominate him to the Heat Treat Today's 40 Under 40 Class of 2020," comments Rosanne Brunello, director of sales at DELTA H. "The process here was a challenge, but our CTO, Richard Conway, answered the call with an innovative and unique furnace design."

A Layman’s Guide to Understanding the Theory of Gases

/ FEATURED NEWS, MANUFACTURING HEAT TREAT, VACUUM FURNACES TECHNICAL CONTENT

Source: VAC AERO International, Inc.

Need a refresher course on the "gas laws" and how they relate to heat treating? What exactly is going on at a molecular level in your vacuum furnace? This best of the web article gives a helpful review of the theory of gases and practical tips to make your heat treating experience easier.

An excerpt:

"The movement of gases is an important and interesting subject but one often dismissed as a topic best left to scientists. However, the Heat Treater needs to know something about the basic nature (theory) of gases and in particular how they behave in vacuum. The main difficulty is that too much theory tends to become a distraction. Our focus here will be to better understand what goes on inside a vacuum furnace."
