[0002] Heat treatment furnace refers to an electric furnace or fuel furnace used for heat treatment of furnace charge. Commonly used heat treatment furnaces include box-type resistance furnaces, pit-type resistance furnaces, gas carburizing furnaces and salt bath furnaces. Continuous furnaces are usually used, and workpieces are continuously loaded from the charging door, passed through the furnace, and continuously unloaded from the discharge door. The commonly used method of conveying in the furnace is to place the workpiece on a heat-resistant steel guide rail and transfer it with a step-by-step moving beam or push rod. In recent years, the method of conveying materials with heat-resistant steel conveyor belts has gradually been adopted. In this way, the heat treatment operation is more rational, which greatly increases the possibility of automation and unmanned management of the heat treatment process.
