[0002] A heat treatment furnace refers to an electric furnace or fuel furnace used for heat treatment of furnace charges. 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 loading door, passed through the furnace chamber, 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, heat-resistant steel conveyor belts have gradually been used to transport materials.

[0003] Heat treatment furnace is an important equipment in the metal processing industry. The furnace core is its core component, and its thermal insulation performance directly affects the heat treatment effect and equipment energy consumption. The existing furnace core has only one layer of thermal insulation material inside, which makes the thermal insulation effect of the furnace core insufficient. The external cold air directly contacts the surface of the furnace core, which will cause heat loss and lead to low heat treatment efficiency. Utility Model Content
