Galvanized steel sheets are classified into ordinary electrolytic plates and fingerprint resistant electrolytic plates. The fingerprint resistant plates apply the fingerprint resistant treatment process based on ordinary electrolytic plates. Fingerprint resistant plates can resist sweat. Usually fingerprint resistant plates are applied to parts without any treatment. The grade is SECC-N. Ordinary electrolytic plates are classified into phosphating plates and passivating plates. Phosphating plates are commonly used. Its grade is SECC-P. It is commonly known as p material. Passivating plates are classified into coated passivating plates and non-coated passivating plates.

Overview of oriented electrical steel
Oriented electrical steel also called grain oriented flat-rolled electrical steel, which refers to cold-rolled electrical steel that contains 2.9%-3.5% Si and possesses the crystal structure of certain regularity and direction. Oriented electrical steel as an essential magnetically soft material of the power industry is mainly applied to the transformer industry, rectifier industry, reactor industry and large motor industry. According to the release of the Ministry of Commerce, dumping occurs to oriented electrical steel products imported from Japan, South Korea and the EU, which diminishes the oriented electrical steel industry of China. It is decided that anti-dumping duty will be levied for these oriented electrical steel products imported from these countries and regions as of July 23. The tax rate is 37.3%-46.3%. The enforcement period will be five years.
Purpose of oriented electrical steelOriented electrical steel is an essential magnetically soft material of the power industry. It is mainly applied to rectifier industry, transformer industry, reactor industry and large motor industry and used for fabrication of the iron core of various transformers.Production process of oriented electrical steelOriented electrical steel: Ore---Iron-making---Steel-making---Hot rolling---Pickling---Cold rolling---Annealing---Grain oriented flat-rolled electrical steel (oriented electrical steel)Cold-rolled coils: Ore---Iron-making---Steel-making---Hot rolling---Pickling---Cold rolling---Annealing---Cold-rolled coilsThe key to production of silicon steel of the Goss texture by using oriented electrical steel is the utilization of secondary recrystallization. To realize secondary recrystallization, it is usually required that normal grain growth inhibitor should be added into alloy, such as MnS, etc. The grain growth inhibitor must be able to be distributed inside the alloy matrix dispersedly in the mixed form. When secondary recrystallization occurs, normal growth of matrix crystal will be inhibited effectively. It is also required that it can be eliminated conveniently in the last high temperature annealing to prevent deterioration of the magnetic property of the product. In secondary recrystallization, the oriented nuclei of secondary grain growth are mainly generated through the proper cold rolling process and recrystallization annealing. Since the phase change can damage grain orientation, it is critically important to maintain the single phase during heat treatment.Grain oriented flat-rolled electrical steel sheets can be classified into oriented silicon steel sheets, non-grain oriented flat-rolled electrical steel sheets and dw material. Non-grain oriented flat-rolled electrical steel sheets for motors are usually 0.35 mm and 0.50 mm thick and are mainly supplied in coils. Their silicon content is usually low; the thickness of grain oriented flat-rolled electrical steel sheets for transformers is usually 0.20 mm, 0.30 mm, 0.35 mm and 0.50 mm. Their silicon content is usually high.Application fields of oriented electrical steel
