摘要/Abstract

摘要： 按照1:10相似比利用铅试样在实验室轧机上对热轧U型钢板桩的轧制过程进行模拟,通过改变4种轧制润滑条件、0.6～1.0的5种辊转速差等轧制条件,得出轧制条件与U型钢板桩头部翘曲之间的关系。试验结果表明,对于孔型轧制产生的翘曲程度初步由辊速差引起,但孔型轧制的翘曲程度也随轧制润滑条件不同而变化。为了改善孔型轧制引起的翘曲缺陷,在其他参数不变下可选用0.65的辊速比与未经润滑的轧辊表面参数相配合。

Abstract: According to similarity ratio 1 ： 10, a simulation on rolling process of hot-rolled U-section steel sheet piling is carried out by using laboratory mill with test stock of lead and the relationship between rolling conditions and end bending of hot-rolled U-section steel sheet piling is obtained by change 4 kinds of rolling lubrication conditions and 5 kinds of velocity difference in 0. 6 ~ 1.0. Test results show that the bending degree produced in pass rolling is preliminarily caused by roll velocity difference, but the bending degree also changes with different rolling lubrication condition. In order to improve the bending defect caused by pass rolling process, as other rolling parameters keep constant, it is available to select 0. 65 roll velocity ratio combined with roller surface parameter in no-lubrication condition.
