Vacuum furnace - Wikipedia

A vacuum furnace is a type of furnace in which the product in the furnace is surrounded by a vacuum during processing. The absence of air or other gases prevents oxidation, heat loss from the product through convection, and removes a source of contamination. This enables the furnace to heat materials (typically metals

High Pressure Gas Quenching - ALD Vacuum Technologies

With the development of separate gas quenching chambers, it is often possible to replace oil quenching with high-pressure gas quenching using nitrogen or helium for heat treating case hardening steels or other low alloyed materials. The success of this dry quenching technology is based on its environmental and

Vacuum Pressure Quenching - Solar Atmospheres

in a vacuum furnace, as opposed to oil quenching, for various oil—hardening grades of materials. hen hardening using high pressure gas quenching to optimize gas quenching. A Leeds and Northrup furnace with a 14” wide x 24” deep x. 12” high hot zone with an integral 300 gallon oil quench tank was used for oil.

Gas Quenching - Steels, Heat Treatment, Case Study

The introduction of high-pressure gas quenching in vacuum furnaces in 1977 has given a new horizon to the vacuum heat treatment of tools. Before then, only Helium also has excellent properties as a quench gas; it is used relatively frequently, especially for materials that have borderline hardenability in gas quenching.

High pressure gas quenching vacuum furnace | SIMUWU

The high pressure gas quenching vacuum furnace is mainly suitable for the vacuum and bright quenching of die steel. It can also be used for vacuum sintering and vacuum brazing of other materials such as powder metallurgy and copper alloy. Please share this page. About the author. SIMUWU VACUUM FURNACE.

Vacuum Pressure Quenching & Vacuum Gas Quenching - Spectrum

Spectrum routinely hardens 4340, 4130 materials in section sizes up to 1/4" nominal. The Spectrum Thermal Processing Single Chamber Gas Pressure Quench Furnace is used for larger vacuum work requiring rapid gas cooling and or high vacuum at temperatures up to 2150°F (1175°C). Whether 400 series or carbon
