(Summary description)Heat treatment furnaces are used to treat metals to change the properties and organization of metals so that they have the required physical and mechanical properties. One of the main equipments in the heat treatment workshop of the heat treatment furnace stone metallurgical factory. Due to the diversity of process requirements of the metal to be processed and the differences in thermal systems and temperature systems, there are many types of heat treatment furnaces. Due to the different process requirements of the heat treatment furnace, the temperature range of the furnace is large. Generally, the furnace temperature higher than 650℃ is called high temperature heat treatment furnace; the furnace temperature lower than 650℃ is called low temperature heat treatment furnace. The commonly used refractory materials for masonry heat treatment furnaces are refractory clay bricks and clay heat insulating refractory bricks. At present, fully lined refractory heat treatment furnaces are very common. Common heat treatment furnaces include chamber heat treatment furnaces, car bottom heat treatment furnaces, roller hearth heat treatment furnaces, bell heat treatment furnaces, tower continuous annealing furnaces, pit heat treatment furnaces, chain heat treatment furnaces, etc. 1. Chamber heat treatment furnace Various types of chamber heat treatment furnaces can be used for heat treatment of small and medium-sized parts. Figure 1-25 is a chamber heat treatment furnace with an area of ​​1.59m2, which is used for annealing and quenching of parts. The fuel is coke oven gas. There are two smoke-returning combustion chambers in the lower part of the furnace, each with a burner. The maximum heating temperature of the furnace is 950°C. The main masonry materials required for the furnace: clay drill 12.9t; diatomite brick 1.1t
