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.
Härtewerk Chemnitz GmbH, a commercial hardening plant in Germany, purchased a horizontal, two-chamber furnace with oil or gas quenching and low-pressure carburizing from SECO/WARWICK. It has a heating chamber, loading and unloading vestibule, and a quenching bath. The load can be cooled dynamically in two different media: in an inert gas (1.5 bar abs) in the quenching vestibule above the oil table with gas flow forced with a blower installed in the ceiling of the vestibule or in quenching oil. Permanent graphite insulation in the heating chamber and graphite heating elements ensure long and reliable operation under industrial operating conditions. The heating system provides quick and even heating of the load, also in low temperatures, which makes it possible to reduce the heating time significantly.
SECO/VACUUM, a SECO/WARWICK Group company, received an order for a 2-bar vacuum furnace from a global energy and environmental services company. The single-chamber high-pressure-quench furnace will be utilized for a range of heat-treating processes, including hardening of tool steels and high-vacuum sintering and annealing. The furnace is designed to achieve deep vacuum levels that will allow the company to process materials for nuclear applications. It will replace an older furnace, adding more capabilities and process flexibility.
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.
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 will design and supply a compact vacuum furnace with a heating chamber measuring 400 x 400 x 600 mm (15.75 x 15.75 x 23.6 inches) to Michelin, the largest tire manufacturer in Europe. The furnace will be used for gas hardening in the manufacture of tools for premium tires. It will provide better control over the quality of heat-treated components and reduce the risk of delays. The specialized tools and dies used in the tire production process are mostly treated in vacuum furnaces. Many tire manufacturers engage third-party hardening plants for that purpose, but owning a furnace makes it possible to become independent from third parties.
SECO/WARWICK received an equipment order from Aalberts Surface Technologies for its hardening plant in Dzierżoniów, Poland. SECO/WARWICK will deliver a two-chamber atmosphere furnace, tempering furnace, endothermic atmosphere generator, and loading and unloading devices along with the auxiliary infrastructure. The AFT-type atmosphere furnace is intended for carburizing, hardening, nitrocarburizing and annealing. It is suited for manufacturing various transmission components. According to Aalberts, the new equipment will increase its capacity in Dzierżoniów and allow the company to expand its business to other eastern European countries.
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.
This webinar will discuss the differences between atmosphere and vacuum heat treating, including the quenching options available for vacuum furnaces. It will also provide insight into the advantages of vacuum, solutions to vacuum leaks and the types of vacuum furnaces available. The presentation will be followed by a moderated discussion.
