By cleaning molten steel, controlling casting temperature and withdrawal speed, the compliance ration in ultrasonic inspection of plate was enhanced from 82.5% to 92%.
采取提高钢质纯净度、控制浇注温度和拉速等改进措施，检测合格率由82.5%提高到92%。
The most reason of cracking breakout is badness of arc and high temperature of molten steel and high withdrawal speed.
对弧不良、钢水温度高、拉速快是造成裂纹漏钢的主要原因；
