CRGO CRNGO Silicon Steel Slitting Machine For Transformer Electrical Steel
Silicon steel is low carbon special steel ≤C(0.08%), Si(1.0~4.5%), its producing process is complicated and making cost is higher. It has characters of high magnetoconductivity, low coercive force and high resistivity and thus little loss of hysteresis and eddy current, the purity of silicon steel sheet must be high, sheet surface must be very flat and clean, silicon steel sheet covers 1% of whole steel production, whose main application is motors, transformers, electric appliances, meters, etc. In this condition, the processing equipment for silicon steel sheet must be very precise.
