基于Deform对型钢矫直压下量的研究

Straightening reduction analysis of section steel based on Deform

运用Deform软件对型钢矫直机的压下量进行分析,模拟了1800 mm大型型钢矫直机在矫直过程中其压下量对矫直质量的影响,大压下量矫直时型钢头部变形弯曲幅度较大;小压下量的矫直不能对型钢进行有效矫直。因此,对压下量进行了优化:入口矫直辊的压下量按大压下量方案中的数值来确定,出口矫直辊的压下量按小压下量方案的数值来确定,达到较好的矫直效果。

This paper analyzes bending of section steel straightening machine using Deform software, simulatesthe reduction impact of the 1 800 mm large steel straightening machine on the straightening quality duringstraightening. The steel head is heavier deformed and bent when straightening with a large reduction, but thereisn＇ t effectively straightening with a small reduction. Therefore, the reduction is optimized in the straighteningprogram, the reduction of the entrance straightening rollers is determined by the large reduction, the reductionof the exit straightening rollers is determined by the small reduction. The optimization result has favorablestraightening effect.
