Technical Field
[0001] The utility model relates to the technical field of steel casting processing, in particular to a steel casting annealing device. Background Art
[0002] Steel castings refer to parts made of cast steel, which have similar properties to cast iron, but better strength than cast iron. In order to reduce the hardness of steel castings and improve their machinability, they need to be heat treated using annealing equipment. Annealing is a heat treatment process that is mainly used to improve or eliminate the structural defects and residual stress generated by materials during casting, forging, rolling and welding, and to prevent deformation and cracking of workpieces. This process changes the microstructure and properties of the material by slowly heating the material to a certain temperature, keeping it for a sufficient time, and then cooling it at an appropriate speed.
[0003] When the annealing device is in use, most heat treatment furnaces are not equipped with a cover plate, which causes the heat in the heat treatment furnace to gradually dissipate during the heating process, resulting in high energy consumption. After the annealing operation is completed, the operator is required to manually pull out the placement rack with the steel castings to remove the steel castings, which brings certain risks to the operator.
