Wisconsin Oven ships batch oven to Flame Treating to temper steel parts
January 30, 2017
Source:
Wisconsin Oven Corp., East Troy, Wis., has shipped a natural gas-fired draw batch oven to Flame Treating Systems Inc. in Durham, N.C., for tempering various steel parts. Flame Treating provides customized flame hardening systems to customers, and also provides in-house flame hardening services. The addition of this tempering oven allows the company to efficiently temper parts in-house.
The tempering oven has a maximum temperature of 1250°F and basket dimensions of 4x3x4 feet. Steel parts are loaded into the draw batch oven in the basket on two stainless steel pier rails with the load capacity of 2000 pounds gross. The recirculation system features a combination air flow arrangement that utilizes a 7000 CFM @ 10 HP plug-mounted blower. The combination airflow arrangement provides both horizontal and vertical upward airflow, which maximizes heating rates and temperature uniformity of the product.
"We are starting to do a significant amount of flame hardening for customers in our shop now," says Mark Sirrine, President of Flame Treating Systems Inc. , "so we needed a better solution than sending parts out for tempering. We installed the oven in the warehouse room adjacent to our 2000-lb. capacity spin flame hardening machine. Five days later it was in production, tempering batches of 800-pound sprockets. That pretty much tells you what you need to know about the ease of installation. We're looking forward to continuing to expand our services in the mid-Atlantic region for both localized hardening and tempering."

Can-Eng to build continuous T-7 heat treatment system for aluminum castings
January 29, 2017
Source:
Can-Eng Furnaces Intl. Ltd., Niagara Falls, Ontario, has been contracted to design, manufacture, and commission an automated T7 Heat Treatment System for the processing of high-integrity aluminum automotive structural castings for a company in the European Union. The Can-Eng design was chosen for this new facility because it offers inherent part handling features that reduce floor space requirements and energy consumption, while providing predictable mechanical properties and dimensional stability of the castings.
The high-volume continuous line includes integrated handling systems connected to up/down stream processes. The T-7 system integrates a robotic handling solution furnace with Precision Air Quench (PAQ) technology, an artificial aging system, and controls integrating Level II SCADA system. The PAQ system integrates a unique combination of features that have been developed through continuous system improvements and modeling carried out in over twenty similar systems commissioned in recent years.
The PAQ system uniformly delivers controlled quenching processes that provide repeatable and uniform mechanical properties and accurate dimensional results. The system is scheduled to be delivered and commissioned to the EU in the third quarter of 2017.

Wallwork Group, U.K., announces that the scope of Rolls Royce approvals for the Bury (Manchester) site of metal thermal processing specialists Wallwork Group, has been extended to include the company's new vacuum brazing facility. Wallwork already undertakes aerospace work for Rolls Royce and it is hoped the new vacuum brazing unit with attract even more high-value contracts.
"Bury is the largest of our three UK sites and already has extensive approvals for metal heat treatment processes," explains sales manager Howard Maher. "Vacuum brazing is a relatively new addition to the services at this location and is a natural addition to the other high vacuum processes that we operate. Achieving Rolls Royce approval so soon after commissioning the new vacuum brazing development laboratory and assembly area is another feather in our cap." Bury is the lead aerospace processing site in the Wallwork group and already has extensive approvals for mainstream heat treatments such as case hardening, carburizing, hardening and tempering, nitriding, and many other common processes. In addition to further Rolls Royce approval, the company also carries approvals from other aerospace primes, such as BAe Systems, Airbus, Safran, Bombardier, Moog and many others, for specific heat treatment processes.

One Minute Mentor: Removing the Passive Layer in Low-Temperature Gas Nitriding
January 27, 2017
Source:
The recent advent of low-temperature gas nitriding (for the production of the S-phase in stainless steel) as opposed to regular high-temperature (above 550 °C) gas nitriding (of regular steel) had to find a way to remove the passive layer in this low-temperature condition.
Patent EP 1707646 B1 (2005): The process set forth in this patent uses a gaseous carbon donor compound (such as acetylene, ethylene, propane, butane, or carbon monoxide) with ammonia at temperatures greater than 570°F. It is carried out in a reactor vessel made of metal such as iron, nickel, cobalt, etc. The catalytic action of the reactor vessel will generate HCN. The HCN will depassivate the stainless steel surface through the following reactions:
2NH + C2H2 → 2HCN + 3H2
Cr2O3 + 6HCN → 2Cr(CN)3 + 3H2O
The carbon and nitrogen in 2Cr(CN)3 diffuse inward and form the nitrocarburized case, leaving a clean surface. The dewpoint must be kept below 40 °F to keep the metal surface being treated from repassivating, which means that the flow of gas must be continuous to eject excessive water formed during the depassivation and nitrocarburizing reaction. After the depassivation step, ordinary gas nitriding with NH3 + H2 + N2 atmosphere can be carried out as desired. The exhaust gas is burned and decomposed at the exit as nitrogen and CO2.
