以弹塑性变形理论为基础,基于DEFORM-3D有限元软件,验证孔型设计的可行性、实用性达到优化孔型设计的目的。250×18号角钢为等边角钢即两腿的宽度或腿长相等均为250mm、腿厚为18mm的大型角钢。孔型轧制是角钢生产的主流方法,因此,设计出合理的孔型是轧制合格角钢的第一步也是最关键的一步,由于国内目前生产此类大型角钢的经验缺乏,所以设计出一套合理的孔型是有难度的,本文主要是通过理论计算方法设计出孔型尺寸,在将孔型生成三维立体图形导入有限元软件DEFORM-3D中模拟轧制,分析模拟结果优化孔型参数,设计出合理的25﹟钢的孔型。
Based on the theory of elastic-plastic deformation, based on DEFORM-3D finite element software, the feasibility of hole design was verified and the practicability was achieved to optimize the hole design. Angle of 250 × 18 for the equilateral angle that is the width of both legs or legs are equal to the length of the legs are 18mm 18mm large angle. Pass rolling is the mainstream method of angle steel production. Therefore, to design a reasonable pass is the first step of rolling the qualified angle and the most crucial step. Due to the lack of experience in the current domestic production of such large angle steels, In this paper, the hole size is designed by theoretical calculation method. After introducing the hole shape into the finite element software DEFORM-3D to simulate rolling, the simulation results are optimized. , Designed a reasonable 25 # steel hole.
