我厂60优质钢钢锭模由于加工工艺的要求,初期设计为上大下小开底式带保温帽圆形钢锭模。锭模主要尺寸为:本体高2米;平均直径426毫米;高宽比(H/D)4.7;锥度2.5%,帽部浇高350毫米,钢锭单重2.32吨。后根据生产实践锭型更改为封底式带保温帽圆形钢锭模,锭模主要尺寸未变。从锭型看,其特点为:圆型、高宽比大、锥度小,由于圆型锭周边长度比同一面积方形锭小1.3倍,比波纹形钢锭小1.6倍,故冷却效应差;兼之高宽比大,因而钢锭
I plant 60 high-quality steel ingot mold due to the requirements of the processing technology, the initial design for the next big small open-end with a round ingot mold insulation. The main dimensions of the ingot mold are as follows: the body is 2 meters high; the average diameter is 426mm; the aspect ratio (H / D) is 4.7; the taper is 2.5%; the cap is 350mm high; According to the production practice after the ingot change to back cover with a round ingot mold insulation, ingot mold main dimensions unchanged. From the spindle type, its characteristics are: circular, high aspect ratio, taper is small, because the round ingot circumference than the same area square ingot 1.3 times smaller than the corrugated ingot 1.6 times smaller, so the cooling effect is poor; Aspect ratio, thus ingot
