中厚板爪裂与氧化铁皮压入相关性试验研究

EXPERIMENTAL STUDY ON CORRELATION BETWEEN CLAW CRACK AND INDENTATION OF IRON OXIDE OF PLATE

通过试验对比氧化铁皮压入与爪裂的出现位置，修磨前后形貌，得出氧化铁皮压入不是导致爪裂的原因。

Through the experimental comparison of the appearance of the oxidized iron sheet and the claw crack, and the morphology before and after grinding, it is concluded that the oxidized iron sheet pressure penetration is not the cause of the claw crack.
