The production process of silicon steel includes:
Pickling
Through the descaling machine and the hydrochloric acid tank, the oxides of the hot-rolled steel strip are removed to prevent the surface defects of the cold-rolled finished product.
cold stamping
In order to ensure the thickness and material for different purposes, the deceleration ratio is set at 40%-90%, and advanced control equipment such as automatic thickness control and automatic shape control are realized.
annealing
It is a process of softening the steel strip material hardened in the cold stamping process. Through metal heating and rapid cooling, steel for deep processing and high-tensile steel are produced, and boxing (cover retreat) annealing and continuous annealing are used.
insulating coating
When processing silicon steel sheets into iron cores, in order to improve the processing performance and prevent the loss of eddy current equivalent to the thickness of the steel sheet, continuous coating equipment is used to spray insulating coating liquid on the top and bottom of the steel sheet.
