孔型设计者的任务不仅要能设计出新品种产品的轧辊孔型,尚应保证轧机有高的产量,产品质量好并生产成本低等,但往往由于经验不足及资料的缺乏(主要如辊轧压力,能量消耗等)不能很好的满足以上要求。例如辊轧压力值,目前虽然有很多公式来计算平均单位压力值,但在使用时都有其局限性,不能保证结果准确;苏联学者在这方面进行了很多实验工作, The task of the hole designer is not only to design the roll pass of the new product, but also to ensure the high output of the rolling mill, the good quality of the product and the low production cost. However, due to lack of experience and lack of data Rolling pressure, energy consumption, etc.) can not well meet the above requirements. For example, the roll pressure value, although there are many formulas to calculate the average unit pressure, but its use has its limitations, can not guarantee accurate results; Soviet scholars conducted a lot of experimental work in this regard,
