[0002] A casting is a metal-shaped object obtained by various casting methods, that is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other pouring methods, and then cooled and polished to obtain an object with a certain shape, size and performance. For die-castings, die-castings are a type of pressure-cast parts. A pressure-casting mechanical die-casting machine with a casting mold is used to pour liquid copper, zinc, aluminum or aluminum alloy metals into the feed port of the die-casting machine. The die-casting machine is die-cast to cast copper, zinc, aluminum or aluminum alloy parts of the shape and size restricted by the mold. Such parts are usually called die-castings. When processing die-castings, a heat treatment furnace for producing die-castings is required. 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.
