Outside the annealing furnace
Heat treatment furnace is a general term for industrial furnaces for various process heat treatment of metal workpieces. The temperature is generally lower than that of the heating furnace. The heat treatment furnace can use various furnace types, but requires stricter control of furnace temperature and furnace atmosphere. Most of the heat treatment furnaces are heated by gas fuel. In order to accurately control the furnace temperature, some heat treatment furnaces are heated by electricity. Modern heat treatment (especially chemical heat treatment) processes are becoming more and more complex, and there are many forms of heat treatment furnaces. For the continuous heat treatment process, a suitable continuous heat treatment furnace must be equipped; for the heat treatment process of periodic work, a controlled atmosphere of forced circulation and the operation of the furnace should be mechanized and automated.
