摘要
为了解决高精度 (J级 )合金冷带在生产中常出现厚度偏差异常波动现象 ,对其产生原因进行了分析 ,并根据产生原因采取了相应的改进措施 ,如过共析钢开坯时压下率应大于 1 0 %、冷轧开坯带卷一般不并卷退火 ,退火时带卷底部垫高 3 0 0mm等等。
For eliminating the thickness deviation abnormal fluctuating of high precision alloyed cold rolled strip(J grade),the causes were analyzed,and the relative preventive measures were put forward,such as the draught of blooming increasing more than 10% for hypereutectoid steel,coil uncombined annealing and the bottom enhancing 300mm during annealing,etc
