一、前言传统的中小型线材轧机,由于采用开口或闭口机架,传力路线长,结构刚性不好,轧材质量不高。遵照伟大领袖毛主席“自力更生”、“我们必须打破常规,尽量采用先进技术”的教导,陕西重型机器厂着手设计和研制新型轧钢机。新机架的结构形式与传统的形式不同,尚无成熟的计算方法可循。因此,我们用光测和电测方法,对新型轧机机架模型进行应力测定。新轧机采用两辊交替悬挂式的结构。其主要参数如下: 轧辊直径ф300毫米(可在ф290～320毫米范围内变动)
First, the preface The traditional small and medium sized wire rod mill, due to the use of open or closed rack, transmission line length, structural rigidity is not good, the quality of rolled material is not high. Following the teachings of the great leader Chairman Mao, “Self-reliance,” “We must break the routine and try to adopt advanced technologies,” the Shaanxi Heavy Machinery Works started to design and develop a new type of rolling mill. The new rack structure and the traditional form of different forms, there is no mature method of calculation to follow. Therefore, we use light and electrical measurements to measure the stress of the new mill stand model. The new mill uses two rollers alternately suspended structure. The main parameters are as follows: roll diameter ф300 mm (can be ф290 ~ 320 mm range)
