Japanese Patent JP2002543274
Kind Code:
A
Abstract:
Method for producing non-grain-oriented electric sheet comprising:introducing steel input stock as a heated and prerolled slab into finishing rolls at a temperature of <=1100° C. wherein the reheating temperature (TBR) corresponds to a reheating target temperature (TZBR) determined by the formula:whereinTZBR(° C.)=target temperature of the reheated slabGSi=Si content in weight %GAl=Al content in weight %hot rolling to a thickness<3.5 mm at a final rolling temperature (TET)>=770° C.coiling at a temperature (THT) whereinwhereind0=reference thickness of the strip=3 mmd=actual thickness of the strip in mmt=time in seconds between the end of hot rolling and coilingalpha=0.7/sec. to 1.3/sec. cooling factorpickling and cold rolling to a thickness of 0.2-1 mm.
