SECO/WARWICK received an order for a vacuum furnace with vertical insertion of loads from a manufacturer of feed machinery and contractor for agricultural engineering projects in India. The furnace will be used in the production of ring dies and rollers for palletizing equipment. These parts are used in many common large-dimension agricultural machines. The vacuum unit, which has a gross load weight 5,510 pounds (2,500 kg) of and workspace dimensions of 59-98 inches (1,500 x 2,500 mm), will also be used for commercial heat treatment of tools steels – mainly carburizing, hardening and tempering.
SECO/WARWICK will deliver a vacuum furnace to a European manufacturer of heavy equipment. The furnace, which has workspace dimensions of 600 x 600 x 900 mm, will be used for hardening and tempering processes for steel. Its design has been customized in order to meet the demands of a dedicated thermal process used in the production of aircraft landing gear. SECO/WARWICK engineers fitted the furnace with a non-standard system for sub-quenching with liquid nitrogen, which enables the required quick cool-down of landing-gear components.
An international aircraft controls manufacturer ordered a low-temperature vacuum furnace from SECO/VACUUM, a SECO/WARWICK Group brand, for tempering, aging and other processes. The furnace will ensure bright part surfaces after treatment in lower temperatures. It is designed to operate up to 1380°F (750°C) with work-zone dimensions of 24 x 24 x 36 inches and a load capacity 1,750 pounds. The furnace meets class 2 TUS requirements per AMS 2750F and is capable of nitrogen convection heating and cooling. This is the fifth vacuum furnace supplied by SECO/WARWICK Group to this company, which operates multiple facilities in the United States and Asia.
SECO/WARWICK will supply an electric mesh-belt furnace to bolt manufacturer Solvera Gawel Technology S.A. The line is designed mainly for carbonitriding and hardening processes and for washing and tempering of high-quality screws and other hardware manufactured near Rzeszów, Poland. The process line, which will be delivered in 2022, will be adapted for operating with endothermic atmosphere supplied from an external endothermic generator. It will consist of a loading module equipped with a weighing system, a main furnace, oil bath (for hardening the workpieces), and vibration and reloading tables. After the hardening process, the workpieces are transferred to a drum washer where they are washed, rinsed and dried.
Can-Eng Furnaces International Ltd. has been awarded two contracts from a producer of high-volume specialty automotive fasteners. Can-Eng will supply two mesh-belt heat-treatment systems, which will include: computerized vibratory loading system, rotary phosphate removal washer, mesh-belt hardening furnace, oil-quench system, post-quench wash system, mesh-belt temper furnace and part containerization system. The fully integrated systems feature Can-Eng’s PET (process enhancement technology) system, which provides the client with complete product traceability through the thermal process, process data collection, historical event archiving, process variable trend monitoring and scheduling optimization.
SECO/WARWICK will deliver two vacuum furnaces to Flansch-Tech, a specialist in aluminum and steel forging, in Budapest. According to SECO/WARWICK, one of the vacuum furnaces will be the largest in Hungary. The Vector with horizontal charge loading is equipped with a 15-bar nitrogen cooling gas-pressure system and a production work area of 900 mm wide x 900 mm high x 1,200 mm long). It will be used for the heat treatment of tool steels – mostly dedicated to hardening and tempering – and will allow Flansch-Tech to process larger parts.
L&L Special Furnace Co. Inc. shipped a dual-chamber heat-treating and temper furnace, along with an oil-quench tank, to an eastern European ammunition manufacturer. The equipment will play a supportive role in keeping key production equipment online along with thermal processing of munitions projectiles. The furnace has two chambers: the top chamber is rated to 2350°F and is used for heat treating various steels and other nonferrous materials; the bottom chamber is rated for 1250°F and includes a recirculation fan and baffle for tempering, stress relief or preheating.
Lindberg/MPH shipped two gas-fired hardening and tempering furnaces to the manufacturing industry. The large-capacity box furnaces will be used for the normalizing, austenitizing and tempering of forged components. The furnaces can accept a maximum load measuring 6 feet wide x 6 feet deep x 6 feet high, and the actual chamber is larger to provide clearance for parts. The outer-shell sidewalls and floor are constructed from 3/16-inch steel plate. The lining is ceramic-fiber modules that store low amounts of heat and have superior insulating qualities to provide maximum fuel efficiency.
TMK’s Seversky Pipe Plant awarded SMS group the final acceptance certificate for a heat-treatment line for tubes and pipes at its Polevskoy site in Russia. The line has an annual capacity of up to 300,000 tons of pipes with diameters between 168 and 370 mm (6.6 and 14.5 inches), a wall thickness of up to 40 mm (1.5 inches) and lengths of up to 13.5 meters (44.3 feet). The line is able to process small batch sizes and different product groups in a cost-efficient manner.
