Steelmaker Commissions EAFs in Plant Expansion

A major U.S. steel producer recently commissioned an international engineering group with the expansion of its steel plant in Osceola, Arkansas, including the supply of electric arc furnaces and other furnace lines, increasing the plant’s annual output to about 3 million tons of steel.

David Stickler, CEO, Big River Steel

Since commissioning of the new mill in 2017, Big River Steel has been producing high-quality steels, including tube grade sheet for pipeline construction, silicon steels for a wide variety of energy and electric motor applications, and advanced high-strength steels for the U.S. automotive industry.

SMS group will supply BRS with mechanical equipment, electrical and automation systems, and digitalization. After completion of the next expansion, the steel plant will have two electric arc furnaces and two twin-ladle furnaces. Installation of an additional gas cleaning system will ensure compliance with strict environmental legislation. A second strand, a second tunnel furnace, and a further downcoiler will be added to the CSP® plant. Big River Steel’s CSP® plant produces up to 1,930 millimeters wide coils, making it one of the widest CSP® plants in the world. Also as part of this project, the continuous galvanizing line (CGL) will receive an additional coiler.

Also in the second construction stage, Big River Steel will see the installation of the PQA® (Product Quality Analyzer) system developed by SMS group company MET/Con as a central module of the process automation system.

Burkhard Dahmen, Chairman of the Managing Board of SMS group

“I have purchased several technologically advanced steel production facilities from SMS over the past twenty years and I am fully confident that SMS group will again deliver a high-quality mill that sets the standard in terms of product capability, energy efficiency and environmental sustainability,” said David Stickler, CEO of Big River Steel.

“Working closely with the management and staff of Big River Steel, we have succeeded in digitalizing a highly complex steel plant in a way that meets the targets of stable and resource-saving production,” said Burkhard Dahmen, Chairman of the Managing Board of SMS group. “We are very pleased about Big River Steel’s decision to also award us the order for the next expansion stage of the steel plant and to continue on the proven successful way with SMS group as their partner.”

DC53 Steel, a general purpose cold work mold and die steel with exceptional strength and resistance qualities, is nonetheless “only as good as the heat treatment it receives,” according to our Best of the Web resource today. Not surprisingly, manufacturers find these excellent characteristics for machining applications.

The folks at International Mold Steel, Inc., a steel distributor in Florence, Kentucky, have compiled a primer on heat treating DC53, which is known not only for its strength and resistance, as mentioned, but also for have a higher hardness than D2 after heat treatment. This is critical for machining shops where die and mold life expectancy is dependent upon proper high-temperature tempering and high hardness.

Temperature Control System Improves Precision, Efficiency on Heat Treat Equipment: A Case Study

A century-old producer of die forgings recently needed to improve the process controls on its heat treating furnaces.

With process controls well over 10 years old, Clifford-Jacobs turned to Conrad Kacsik to improve its temperature process control system. The company, which serves a number of industries, including energy, aerospace, construction, mining, forestry, and rail, was eager to improve its temperature process control system, particularly because the incumbent system was producing inconsistent work.

The Challenge

Bud Kinney, Vice President of Innovation and Technology at IMT Corporation

Clifford-Jacobs was not getting consistent, repeatable results from its furnaces. The company also wanted more efficient and automated processes with data acquisition and electronic operating capability.

“We looked at a number of controls companies throughout the Midwest and interviewed them to learn about their experience with system controls and data acquisition,” said Bud Kinney, Vice President of Innovation and Technology at IMT Corporation, the parent of Clifford-Jacobs. “We knew we wanted an integrated system so we started looking at companies that did that as a matter of course. Most companies are limited to traditional controls, but Conrad Kacsik has a lot of experience doing the exact type of job we needed.”

Increasing Demands

Clifford-Jacobs makes forged parts for a variety of clients. Although forging does not generally require as much precision as other types of processes, customers are increasingly demanding, said Kinney.

“We believe that sooner rather than later things like Nadcap will come into forging, and our customers are very interested in us being able to demonstrate that our processes are always in control, even forge heating,” Kinney said. “This project helps ensure that we meet those needs. We couldn’t track things like set-point input values before. That’s another element we wanted to manage.”

The System

Retrofitting Clifford-Jacobs heat treating system.

Conrad Kacsik built a full process temperature control system that includes SCADA software from SpecView. They were able to retrofit the system on Clifford-Jacobs’ existing 16 furnaces, saving the company considerable expense and time. The temperature process control system uses Watlow F4T controllers paired with SpecView SCADA software, which allows for programming jobs/recipes, remote operation, secure (password protected) operation of furnaces and accurate automatic temperature recording. Conrad Kacsik also added alert lights that allow the operators to quickly see the status of each furnace from the shop floor.

H2: Benefits of Temperature Control System Integration

Clifford-Jacobs has noted several beneficial results from the new temperature control system. These include:

  • Increased accuracy. The new system runs each recipe exactly and records the results. The company can also control which employees can adjust temperature settings, preventing operators from rushing jobs with a higher temperature or inadvertently setting the furnace incorrectly.
  • Higher efficiency. With preprogramming, each furnace is always at the exact temperature it needs to be for the given task. An automatic preheat setting also safely prepares the furnace for the workday—eliminating downtime or the need to send an employee in early to start the furnaces.
  • More speed. Clifford-Jacobs can pre-program any recipe it needs, allowing for highly accurate and fast running of complex processes.
  • More convenience. Clifford-Jacobs can operate their furnaces from anywhere with an internet connection, or via an iPad used by an approved employee.
  • Precision for the future. The new system can be part of a Nadcap-approved process should the need arise. The SpecView software and advanced controllers automatically record each job and retain all data for verification.

The Results

“We used to have to use all kinds of resources to provide oversight on temperature control,” said Kinney. “This has given us a heating strategy. We write the recipes we want and just select from those. In addition to that, we know exactly what every furnace is doing at all times.”

The company is also pleased with the increased efficiency. They only heat product when they are ready to run production, and the furnace only uses the exact energy needed for each recipe. They are also saving on staffing, as they used to have to schedule people to ensure the furnace was at the right temperature.

“With this system, we can develop recipes for each part we make, which is both convenient and precise. It’s doing exactly what we expected it to do,” said Kinney.

Heat Treatment of FDM Parts to Determine Effect on 3D Printing: UT-Arlington Study

 

Source: 3DPrint.com

 

A University of Texas at Arlington thesis student recently investigated thermal annealing to determine how to increase inter-bead bond strength overall in 3D printing processes.

Rhugdhrivya Rane tackled the dilemma of weak tensile strength in FDM parts and whether parameters chosen by the user — such as temperature ranges and pressure gradients — can affect an increase in inter-bead bond strength. The researcher used thermal annealing, and thermal annealing with unidirectional mechanical pressure in the Z direction, 3D printing a variety of specimens in ABS. The method of 3D printing was chosen due to its increased popularity in mainstream manufacturing.

“The parts were printed using two different sets of print parameters: high and low settings, to investigate the effect of heat treatment on both sets of print parameters. The values of temperature, time and applied pressure during heat treatment were varied to obtain a detailed comparative study and the correlation between the given variables and the increase in ultimate tensile strength.” ~ Rane

The discovery was that “higher temperatures and longer exposure to heat produced better tensile strength, along with increased ductility.”

“Though thermal annealing and uniaxial pressure cause an increase in the strength of the parts, the print parameters play a vital role in determining the initial mechanical properties of the parts. When the parts are fabricated with a higher value of flow rate and extrusion temperature, they exhibit significantly higher mechanical properties as compared to parts printed with substandard setting,” concluded the researchers. “Thus, by controlling the print parameters and using the right values of temperature and pressure we can see substantial increase in strength of FDM parts.”

Temperature Monitoring and Surveying Solutions for Carburizing Auto Components: AMS2750E and CQI-9 Temperature Uniformity Surveys

Dr. Steve Offley (“Dr. O”), Product Marketing Manager PhoenixTM

This is the final installment in a 4-part series by Dr. Steve Offley (“Dr. O”) on the technical challenges of monitoring low-pressure carburizing (LPC) furnaces. The previous articles explained the LPC process and explored general monitoring needs and challenges (part 1), the use of data loggers in thru-process temperature monitoring (part 2), and the thermal design challenge (part 3). In this segment, Dr. O discusses AMS2750E and CQI-9 Temperature Uniformity Surveys. You can find Part 1 here, Part 2 here, and Part 3 here


A significant challenge for many heat treaters is the need to provide products certified to either AMS27150 (aerospace) or CQI-9 (automotive). To achieve this accreditation, furnace Temperature Uniformity Surveys (TUS) must be performed at regular intervals to prove that the furnace set-point temperatures are both accurate and stable over the working volume of the furnace. Historically, the furnace survey has been performed with great difficulty trailing thermocouples into the heat zone. Although it’s possible in a batch process when considering a semi-batch or continuous process, this is a significant technical challenge with considerable compromises as summarized below.

Trailing Thermocouple TUS Process Steps

Figure 1. Typical TUS thermocouple. Positions — 9 point survey. Furnace void corners and center
  • TUS is often carried out using long or ‘trailing’ thermocouples that exit through the furnace door.
  • Furnace often needs to be cooled, then de-gassed so TUS frame can be set up in the furnace.
  • Thermocouples are then led out through the furnace door and connected to a data logger or chart recorder.
  • The furnace is then heated to surveying temperatures.
  • The survey is then carried out, after which furnace is cooled, and thermocouples are removed.

 

Disadvantages of Traditional TUS Process

  • Lots of furnace downtime may be involved (can be up to 24 hours).
  • Thermocouples have to exit the furnace door.
    • This may involve “wedging” the door up, or “grooving” out the hearth to get thermocouples out.
    • Or thermocouples may get caught in the furnace door.
  • A significant amount of the technician’s time is taken up preparing report.

Applying the “Thru-Process” approach to TUS, the measurement system is transferred into the furnace with the survey frame allowing the setup process to be done quickly, safely, and repeatable. (See Figure 2)

Figure 2. PhoenixTM System loaded into a furnace as part of a TUS frame. Thermocouples pre-fitted to the 8 vertices of the cube frame and center. Furnace ambient temperature recorded either with a virgin exposed junction thermocouple (typical MI) or with heat sink damper fitted.

Operating the system with RF telemetry, TUS data is transferred directly from the furnace back to the monitoring PC where at each survey level temperature stabilization and temperature overshoot can be monitored live with TC and logger correction factors applied. The Thermal View Software is developed to ensure that the final TUS report complies fully to the AMS2750E/CQI-9 standards.

Figure 3. PhoenixTM Thermal View Survey Software showing a TUS profile at three set survey temperatures. The probe map shows exactly where each probe is located and easy trace identification. Detailed TUS report generated with efficiency.

Features incorporated into the Thermal View Software to provide full TUS capability include the following:

TUS Level Library – Set-up TUS level templates for quick efficient survey level specification (Survey Temp °F, Tolerance °F, Stabilization, and Survey Times)

TUS Frames Library – Show clearly exact TUS frame construction and probe location using Frame Library Templates – Frame Center and 8 Vertices.

Logger Correction File – Create a logger correction file to compensate TUS readings automatically from the logger’s internal calibration file.

Thermocouple Correction File – Create the thermocouple correction file and use to compensate TUS readings directly.

TUS Result Table & Graph View – For each TUS temperature level, see from the graph or TUS table instantaneously full survey results.

Furnace Class Reporting – Report the specified furnace class at each temperature level.

 

 

Overview

The PhoenixTM Temperature Profiling System provides a versatile solution for both performing product temperature profiling and furnace TUS in industrial heat treatment. It is designed specifically for the technical challenges of low-pressure carburizing (LPC) whether implementing either high-pressure gas quench or oil quench methodology, providing the means to Understand, Control, Optimize and Certify the LPC Furnace and guarantee product quality and process operation efficiency and certification.
