IPC: C22C38/00
Filed: 1981-09-11
Abstract: PURPOSE:To obtain a steel plate for shielding of the inside surface of color cathode-ray tubes having a desired specific magnetic permeability by subjecting extra low C steel of specified Al/N to controlled cooling after hot rolling then to pressing and a blackening heat treatment after cold rolling via decarburization annealing. CONSTITUTION:The steel consisting of 0.03-0.12% C, <=0.10% Si, 0.10-0.30% Mn, 0.01-0.06% solAl, 0.002-0.010% N, >=7 Al/N, and the balance Fe and unavoidable impurities is hot-rolled. The rolled steel is coiled at <=600 deg.C and Al and N are solubilized. This steel is subjected to cold rolling at >=50% then to decarburization annealing above the recrystallization temp. to decrease C down to <=0.01% and to allow AlN to deposit. Further the steel is cold rolled to 40-90%. The rolled steel plate is formed by pressing and is applied with a blackening heat treatment for 10-30min at 550-650 deg.C, whereby the steel plate for shielding of the inside surface of color cathode-ray tubes having >=600 specific magnetic permeability at 0.35 oersted magnetic field is obtained.
