热轧角钢在型钢产量中占有较大的比重,然而轧制中仍存在许多缺陷,如:腿长、腿短、折叠、偏角等,特别是轧制不等边角钢,更加困难。为了适应对产品质量愈来愈高的要求,研究和改进角钢蝶式孔型设计方法对优质、高产、低耗和改善工人操作等具有重大的意义。一、目前采用的设计方法的分析多年来角钢蝶式孔型设计几乎都是采用米列金的设计方法。这个设计方
Hot-rolled angle steel accounts for a large proportion of the output of the section steel. However, there are still many defects in the rolling such as leg length, short legs, folding, declination, etc., especially for rolling unequal angle angles. In order to meet the requirement of getting higher and higher product quality, it is of great significance to research and improve the design method of angle steel butterfly hole to high quality, high yield, low consumption and improve the operation of workers. First, the analysis of the design method currently used Almost all corners of the butterfly hole design over the years is the design method using Mi Leijin. This design side
