Aalberts Surface Technologies Group will expand their Dzierżoniów, Poland hardening plant with a new AFT process line. The line, based on two-chamber atmosphere furnaces, will boost the plant's manufacturing of transmission components and specialized hardening processes including carburizing, nitrocarburizing, and annealing.
SECO/WARWICK, parent company of North American furnace supplier SECO/VACUUM Technologies, will provide a main furnace, a tempering furnace, and an endothermic atmosphere generator, loading/unloading devices, and auxiliary infrastructure. The line offers both conventional load arrangements with modular accessories and hardening baskets.
"The new line will significantly increase our capacity and will allow us to expand our business to other Eastern European countries,” said Bartłomiej Olejnik, managing director, Aalberts Surface Technologies Heat Sp. z o.o.

A worldwide manufacturer of catalytic convertors, medical devices and pollution environment controls is set to receive 10 bench-top lab furnaces that will be used as part of a precious metals recovery system. The assay division recycles many parts that were originally deployed as catalytic convertors for diesel motors, medical components, and electrical parts.
The precious metals are burned out of the existing product and placed in crucibles. The crucibles are heated in the L&L Special Furnace Co., Inc. model GS1714 at temperatures between 1,800°F/982°C and 2,200°F/1,204°C. This allows any impurities in the metals to rise to the surface and be removed for further refinement. The model GS1714 has an effective work zone of 10” high by 15″ across by 13″ deep.
A Midwest manufacturer of brass components is upgrading their heat treat capabilities with a new furnace. The 24″ wide, 3 zone mesh belt annealing furnace will provide improved energy efficiency, reduced atmosphere consumption, and consistent and reliable part quality, as compared to an older design.
The brass annealing furnace from Gasbarre Thermal Processing Systems is designed with a maximum operating temperature of 1650℉ with a capacity of 800 lbs/hr, and utilizes a blend of nitrogen and hydrogen atmospheres. The system incorporates an Allen-Bradley PLC and HMI with automated atmosphere and water temperature control and datalogging.
An integral quench furnace line was recently commissioned to a manufacturer of specialty nut and bolt assemblies in the eastern U.S. The furnace design will help the client increase their load size, allowing for higher throughput per load.
Gasbarre Thermal Furnace System's integral quench furnace system
The Gasbarre Thermal Processing Systems furnace line includes an integral quench furnace, parts washer, temper, and associated material handling and load storage, and it is designed to process 24” wide x 24” long x 20” tall loads weighing up to 1,500 pounds. It includes custom designed material handing that will eliminate the need for cast base trays.

United States Air Force personnel stationed at Royal Air Force (RAF) Base Mildenhall in the United Kingdom recently commissioned and received full training on the use and maintenance of a heat treating furnace for aerospace parts. The furnace will help maintain KC-135, CV-22, C-130 aircraft, and F-15 fighter jets assigned to RAF Mildenhall or nearby RAF Lakenheath air stations. The installation was interrupted by an impromptu visit from the U.S. President.
Richard Conway Chief Technology Officer Delta H Technologies
The DELTA H® TECHNOLOGIES dual chamber heat treating furnace for aerospace (DCAHT®) was designed by the supplier to rapidly heat treat all common aviation grade metals and alloys necessary for aircraft maintenance and is fully compliant with USAF/NAVAIR Tech Order 1-1A-9 and SAE-AMS2750F. The training received by the USAF airmen at RAF Mildenhall included essential instructions in heat treating, as well as furnace calibration practices like temperature uniformity surveys (TUS) and system accuracy tests (SAT) and culminated with each airman receiving Certificates of Training.
The specialized furnace features an upper chamber convection system, 18" wide x 12" high x 48" deep, capable of Class 1 (+/-5°F) from 200°F to 1200°F and a lower chamber radiant heat system, 12" wide x 12" high x 36" deep, capable of Class 3 (+/-15°F) from 1000°F to 2000°F with air or argon atmosphere. A roll-away quench tank features dual baths for water and oil quenchant. The controls and data acquisition provide detailed batch records of heat treated parts, including quench delay, as well as automatic tracking of thermocouple usage and calibration intervals.
Air Force One at RAF Mildenhall
The training was interrupted by an unexpected visitor to RAF Mildenhall. The hangar next to the Metals Tech Shop, where the furnace was being commissioned and the training was being conducted, was the epicenter for the arrival of a top-secret VIP. When the Air Force Band began practicing "Hail to the Chief," it became obvious that U.S. President Joe Biden would be making an unexpected visit to the base. While the President’s visit was not related to the furnace commissioning, Richard Conway, DELTA H® founder and chief technology officer, and wife Mary Conway, witnessed this presidential visit and got a few candid photographs of Air Force One (see above).
A high-uniformity box furnace has been delivered to Soil Lab, a community-based workshop based in Chicago, as part of the 2021 Chicago Architecture Biennial. The furnace received a fast-track shipment of four weeks to be part of the biennial workshop program in which local community groups will experiment and gain knowledge of ceramic production and various processes.
TheL&L Special Furnace Co., Inc. Model XLE 3636 is a front-loading, refractory-lined box furnace and has an effective work zone of 34” wide by 34" high by 32" deep. There is a horizontal double pivot door with a safety power cutoff switch. A ceramic hearth and standoffs are provided as a workspace for various ceramics and ceramic-based products. Additionally, the furnace has a series of inlets on the side and an outlet on the top. These can be capped off when not in use to preserve heat, and can provide a "candling" effect where various ceramic byproducts can be removed from the furnace. Some of these byproducts can be corrosive and need to be removed from the system.

A multi-unit modular pot furnace system has been set for an aerospace manufacturer in the U.S. to help the end user increase heat treat capacity.
Each of the four Lucifer Furnaces Model 2057 pot furnaces is connected to a single freestanding NEMA 1 control panel. Each furnace is heated electrically with 18 KW of power to heavy duty coiled elements in removable holders on all 4 side walls. Roof and side covers bolted to the frame of each furnace can be removed for easy service access.
The units are insulated with 5" of multi-layer insulation consisting of dry-fit hot face lightweight firebrick backed by cold face mineral wool. A vestibule at the top of each furnace reduces heat loss between the pot wall and firing chamber. Controls onboard include Honeywell DC3500 digital multiprogrammable cascade controllers which automatically interpret multiple thermocouple readings and adjust the inside/outside pot temperature to achieve the desired set point. Additional energy efficiency and power uniformity is maintained with SCR power units.
