For metals such as annealing, tempering, normalizing, and hardening, heat treatment is carried out under different atmospheric conditions at horizontal or vertical angle.
Metal heat treatment furnaces are designed to perform heat treatment (hardening, tempering, etc.) of various metals on a laboratory scale. For the specimen suspended in the middle part of the furnace by means of a wire, hardening can be done under protective atmosphere conditions.
The sample, which is automatically dropped into the liquid placed under the oven, can be cooled suddenly. Heat treatment can be continued without dropping the desired conditions.
