The ones delivered in sheets are called steel plates, also called box plates or flat plates; the ones delivered in long coils are called steel strips, also called coils; annealing is a metal heat treatment process, which refers to slowly heating the metal to a certain temperature, keeping it for a sufficient time, and then cooling it at an appropriate rate. The purpose is to reduce hardness, improve machinability, eliminate residual stress, stabilize size, reduce deformation and crack tendency, refine grains, adjust organization, and eliminate organizational defects. To be precise, annealing is a heat treatment process for materials, including metal materials and non-metallic materials. The annealing purpose of new materials is also different from that of traditional metal annealing. The commonly used equipment for annealing in the heat treatment process is the annealing furnace.
