鞍钢第二初轧厂和中板厂最近几天初步进行了余热淬火试验,取得了比较满意的结果。第二初轧厂用三号甲类沸腾钢,厚18毫米的钢板进行了试验。在轧完温度830℃时,立即喷水冷却,一边喷水一边平正矫直,板形合格,共抗拉强度和屈服点此标准规定提高25%左右,延伸率稍有下降,而冷弯仍合格。中板厂用三号甲类镇静钢,厚6、8、10、12毫米的钢板进行试验。在轧完温度800～920℃
Anshan Iron and Steel Company, the first two early mill and plate mill in the last few days of heat quenching test, and achieved satisfactory results. The second initial mill with a Class A boiling steel, 18 mm thick steel plate was tested. In the rolling temperature of 830 ℃, immediately spray cooling, water while flat side straightening, plate-shaped pass, a total of tensile strength and yield point of this standard increased by about 25%, a slight decrease in elongation, and cold bending is still qualified. Plate factory with a Class A calm steel, 6,8,10,12 mm thick steel plate for testing. Rolling temperature at 800 ~ 920 ℃
