摘要
研究了3830mm超宽X70的轧制工艺。结合实际生产经验,研究工艺参数对其力学性能和板型的影响。结果表明:当一次开轧温度为1100℃,二次开轧温度940℃,终轧温度800℃,返红温度540℃时,性能和板型均比较好。
The paper studies the rolling process of 3 830 mm extra - wide X70 pipeline steel plate. Based on the practical production experiences, the effect of process parameters on mechanical properties and plate shape is investigated. The result shows that better mechanical properties and plate shape can be maintained at start rolling temperature of 1 100 ℃, restart rolling temperature of 940 ℃, finish rolling temperature of 800 ℃ and re -reddening temperature of 540 ℃.
