摘　　要：用电子显微镜和电子探针分析研究了某些低合金钢热轧板分层的现象，找出了产生分层的原因，通过改进热轧板卷曲后的冷却速度控制钢中夹杂物向晶界扩散，达到控制热轧板分层的目的。he lamination appearing in some low alloy steel during hot rolling has been analysed by use of electro microscope and electron probe.The cause of lamination has also been search out and an approach is advanced by improving the cooling velocity for warped plate thus controlling interior impurities from diffusing into the grain boundary, so as to achieve ones aim of weakening lamination. The measures for avoiding lamination are presented.
