Abstract

PURPOSE:To have a less unevenness of hole shape and not to change the hole shape by press processing, by making Al killed cold rolled steel sheet having a specific constitution, limited the value of sol. Al/N by carrying out hot and cold rolling -annealing- skin-pass rolling of slab at the time of manufacturing color TV shadow mask. CONSTITUTION:Al killed cold rolled steel sheet composed of C<=0.01%, Mn; 0.1-1%, S<=0.025%, Sol.Al; 0.01-0.12%, N<=100ppm, Fe and inevitable impurities; balance and made (Sol.Al/N)X14/27>=1.5 and also fixed a greater part of N as AlN, is obtained by carrying out hot.cold rolling -annealing- skin-pass rolling of slab. Next, the above cold rolled sheet is cold rolled (draft 40%) again and thickness of the sheet is made 0.2mm or less. Then, the last annealing is carried out at 600-800 deg.C for 1-10 minutes after perforating by photo etching in usual shadow mask manufacturing process.
