Workpieces are heated to an appropriate temperature, insulation is performed for a period of time according to the material and size of workpieces, and then workpieces are cooled down slowly (the lowest cooling speed) to make the internal structure of metal reach or approach to a balanced state, so as to achieve good process performance and service performance or make preparation for further quenching.

A smelting furnace is the equipment where metal ingot and some scrap metal are melted, necessary alloy compositions are added, and then slagging-off and refining are performed to generate the targeted alloy through smelting.
