文档介绍：2050四棍轧机(F5)设计
摘要
目前,随着国民经济高速的发展,钢铁企业也迅猛发展。带钢的应用变得更加广泛,例如:厂房设备、机械设备、桥梁、高速公路等。为了适应新形式的发展需要,我国自行设计制造了2050热带钢连轧机,产品质量达到。它是2050四棍热连轧机的第五架轧机,本文通过对F5精轧机的设计计算,了解了机械设计的一般设计方法,通过对局部结构进行改造,使结构更合理。本设计的设计内容是根据轧件要求,确定轧制力,轧制力矩,并对电机、主传动装置等进行了合理的选择和校核。选取主要部件如轧辊,机架,齿轮座等结构尺寸并校核,另外还对轧机系统的环保和经济技术进行了合理的分析。

The Design of the 2050 Four Roller Mill (F5)
Abstract
At present,along with national economy high speed development, iron and steel enterprise also swift and violent development. The belt-shaped steel es more widespread, for example: Workshop equipment ,mechanical device ,bridge highway and so on . For the new situation development need .quality of the products of the 2050 hot strip tandem mill .Which is designed and manufactured by our own country,The F5 finishing mill is the fifth frame of the four-high hot tandem , by designing and calculating to the F5 finishing mill, I find out the general design procedures of mechanism designs .By improving on the part structure and carrying the optimize design .The contents of my design are to ascertain the rolling force and rolling torque ,And to the electrical machinery ,the main drive and so on has carried on the reasonable select and the examination ,The next step is to select the structure dimensions of the critical pieced which contain the mill rolls ,Moreover also has carried on the reasonable analysis to the rolling mill system environmental protection and the economical technology .
Key words: framework ,rolling force ,mill rolls ,environmental protection ,check
