Variety of Furnaces Can Be Used for Heat Treatment of

Varying the gas/air ratio, or using a different "feed" stock (natural gas or propane for example) will cause the chemistry of the gas to change. Vacuum Furnaces Vacuum furnaces (Figure 5) can be classified, according to the mode of loading into horizontal and vertical and can be further subdivided into batch or continuous (multi-chamber) designs.

Electric arc furnace

In some twin-shell furnaces, the scrap is charged into the second shell while the first is being melted down, and pre-heated with off-gas from the active shell. Other operations are continuous charging—pre-heating scrap on a conveyor belt, which then discharges the scrap into the furnace proper, or charging the scrap from a shaft set above the furnace, with off-gases directed through the shaft.

Heat Treatment Furnace Atmospheres: Inert Gas and

Class 300: endothermic base formed by the reaction of a fuel gas and air mixture in a heated chamber filled with an appropriate catalyst Class 600: ammonia-based There are other classes, but they do not fall within the scope of inert or hydrogen-rich atmospheres.
