Abstract

PURPOSE:To produce a titled blank material by hot rolling a low-carbon aluminum killed steel material, taking it up in coil, annealing the same for a short time after cold rolling then cold rolling the same again. CONSTITUTION:A low-carbon aluminum killed steel contg. 0.005-0.10% C, 0.10- 0.50% Mn, 0.002-0.025% Si, 0.02-0.08% Sol Al,0.004-0.01 Ni by wt% and consisting of the balance Fe and unavoidable impurities is hot-rolled by an ordinary production process. It is next taken up in coil at below 600 deg.C. Such steel plate is cold-rolled at >=50% draft, and is subjected to annealing for a short time under the conditions of within 5min at steel plate temp. between 500 deg.C-Ac1 point. Thereafter, it is again cold-rolled at >=50% draft to make plate thickness <=0.2mm.. In this way, the blank material for shadow masks of superior high-temp. strength is produced.
