SECO/WARWICK received an order from Aalberts Surface Technologies for two vacuum furnaces to be delivered to the group’s TEY plant in Spain. One of the furnaces ordered is the largest from SECO/WARWICK’s portfolio: a horizontal retort furnace for high-efficiency tempering with vacuum purging. The retort furnace will increase the processing capacity of Aalberts’ hardening plant for tempering processes. The other furnace ordered, a Vector with a useful working space of 23.5 x 23.5 x 35.5 inches (600 x 600 x 900 mm), will increase the efficiency of the hardening plant.
ASM’s subcommittee recommends that a long-cycle deep-cryogenic treatment (DCT) followed by a low-temperature temper (LDCT+T) should be the standard DCT practice. Many investigations by researchers using this standard and case studies cited positive results, but there have also been investigations that cited negative results.
SECO/WARWICK will supply a vacuum furnace to Atlas Autos Ltd., the largest manufacturer of motorcycle parts in Pakistan. The furnace is intended for hardening and tempering processes, and it will be used for special large-size die production. The furnace, which has an effective work zone measuring 600 x 600 x 900 mm (23.5 x 23.5 x 35.5 inches), will improve and increase Atlas Auto’s hardening process capacity and will also improve the economics of the plant’s process production. It is currently in the production stage and will be shipped to Pakistan in the second half of 2022.
L&L Special Furnace Co. received orders for a floor-standing box furnace for heat treating saw blades and for a large floor-standing, fiber-lined furnace that will be used to stress relieve and temper large steel castings. The box furnace has an effective work zone of 34 inches wide x 34 inches high x 44 inches deep and includes an electric vertical door, an alloy hearth and a complete control system. The furnace's primary function is to heat treat a range of tool steels that are used for saw blades. The floor-standing furnace has an effective work zone of 36 inches wide x 36 inches high x 72 inches deep. It includes a pneumatic vertical door, 24-inch-high convection alloy fan, a complete control system, castable piers and a cast-alloy load platform for forklift loading.
A Czech manufacturer of industrial knives, mulching knives and chippers placed an order with SECO/WARWICK for a vacuum furnace with 10-bar high-pressure gas quenching. The furnace, which has been customized to enable the processing of long and straight items, will be used for tool-steel hardening and tempering. SECO/WARWICK engineers designed a nonstandard workspace measuring 600 x 600 x 1,800 mm (23.6 x 23.6 x 71 inches). The modification was implemented to fit the characteristic shape of the workpieces. Apart from the nonstandard dimensions of the chamber, the unit was fitted with a directional cooling option to effectively cool long and thin knives that are prone to distortion during the hardening process.
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.
