Electrical steel, also known as silicon steel sheet, is an indispensable and important soft magnetic alloy for the electrical, electronic and military industries, and is also the metal functional material with the largest output, mainly used as a variety of motors, Cores for generators and transformers. Its production process is complex, the manufacturing technology is strict, and the foreign production technology is protected in the form of patents, which is regarded as the life of the enterprise. electrician The manufacturing technology and product quality of steel plate is one of the important indicators to measure the level of special steel production and scientific and technological development of a country.
Converter steelmaking → continuous casting → hot rolling → normalizing → pickling → cold rolling → continuous annealing → coating → rewinding → packaging
Control the composition of various elements in molten steel, reduce harmful elements such as P, S, O and N, and accurately control the amount of core elements such as Si and Al.
At the same time, reduce the final rolling temperature and increase the coiling temperature, coarsening the grain, MnS and AlN, improving the texture and magnetism of the hot rolled plate.
The normalizing treatment makes the grain structure more perfect, uniform and coarser after hot rolling, and improves the texture and magnetism. After normalization, shot blasting and pickling are carried out to remove the surface of the steel strip.
Rolling below the recrystallization temperature makes the steel plate reach the target thickness through continuous cold deformation. Good shape and thickness tolerances can be obtained by controlling the tension.
Continuous annealing eliminates strain from cold rolling by recrystallization and promotes grain growth. Decarbonization to ensure that magnetism, hardness and magnetic aging meet requirements.
