Method of fabricating very thin cold-rolling steel sheet for inner shield excellent in magnetic shield

1998 
PURPOSE: A method of fabricating a cold-rolling steel sheet is provided to economize in cost by making a cold-rolling steel sheet for an inner shield excellent in magnetism through two cold-rolling processes without annealing. CONSTITUTION: A steel slab consists of less than 0.0025wt% of carbon, 0.05-0.25wt% of manganese, 0.05-0.15wt% of silicon, less than 0.015wt% of aluminium and the rest such as iron and other impurities. After hot-rolling the steel slab at a temperature over 910°C, the steel slab is primarily cold-rolled. A cold-rolling steel sheet is fabricated by cold-rolling the steel slab secondarily after being annealed.
