机架是轧钢机最重要的零件之一,机架应结构合理,具有足够富裕的强度和刚度,以保证其工作可靠。 过去的机架设计,是按照结构分析能量法来确定机架中的应力和变形。按静力强度计算时,基于要求工作可靠和一些难于估计的因素,安全系数一般不小于8～12。尽管如此,有时仍然出现破坏。其原因除了材料、制造存在的缺陷外,计算方法不精确亦是原因之一。实
Rack is one of the most important parts of rolling mill, the rack should be reasonable structure, with sufficient strength and rigidity to ensure its reliable operation. In the past rack designs, the stress and deformation in the rack were determined according to the Structural Analysis Energy Method. According to the static strength calculation, based on the requirements of reliable work and some difficult to estimate the factors, the safety factor is generally not less than 8 ~ 12. In spite of this, destruction sometimes still occurs. The reason for this is not only the lack of materials and manufacturing, but also the inaccurate calculation method. real
