What are the types and parameters of silicon steel sheet?
For example: Baosteel, B50A470, Wuhan steel, 50WW470 mean no change, 50 represents the thickness of silicon steel is 0.5MM, 470 represents the maximum iron loss of silicon steel sheet is 4.7, W represents no orientation.Silicon steel sheet is a kind of soft ferromagnetic alloy with low carbon content. The silicon content is generally 0.5 ~ 4.5%. The addition of silicon increases the resistivity and maximum permeability of the iron, reduces the coercivity, the core loss (iron loss) and the magnetic aging.
Hot rolled silicon steel sheet is melting Fe-Si alloy with open hearth furnace or electric furnace, repeatedly rolled into sheet, finally made at 800-850 DEG C after annealing. Hot rolled silicon steel sheet is mainly used in the manufacture of generator, so it is also called hot rolling motor and silicon steel sheet, but its utilization rate is low and energy consumption is great. In recent years, relevant departments have been forced to be eliminated.
Non oriented silicon steel is basically 0.5 thickness, followed by 0.35 and 0.65, two kinds of thickness. High grades and low grades. High grade is more than 470 brand (thickness is basically 0.35 and 0.5), the brand is 470 brand (thickness is basically 0.5). The low grade is 600-1300 brand (the thickness is basically 0.5 and 0.65). In addition, there were 1600 brands, which are rare now.
Oriented silicon steel sheet is basically 0.3 of the 120130 brand, more commonly used. A lower brand is the 145155 brand of the 0.35 series. High point is 0.27 of the thickness of 110100105., and then higher is 0.23 of the thickness of 085080 and so on. The performance is high, magnetic induction is low, and plain oriented steel.
