Description:
The rolling process with warm for cold-rolled non-oriented electrical steel in pickling and rolling and continuous annealing was studied. Research shows when feeding the hot plate for Pickling and rolling mill in 100~120°C, pickling steel is almost no temperature rise, with the temperature of hot rolled silicon steel pickling effect is good, the cleaning rate reaches 100%; the steel sheet is stable running in looper for the strip temperature softening effect and shape of rolled strip is good, deviation below 8μm. Cold rolled plate feeding in 60~80°C for continuous annealing unit, the plate is almost no heating in Alkaline wash. Alkaline wash effect is good for the cold rolled plate with temperature steel, plate surface defect can be significantly reduced and wash rate is up to 100%; steel plate with temperature is not deviation in continuous annealing looper for softening. In addition, organization, texture, the second particles and magnetic energy also were studied. It was foun...
