万能轧钢机的界说和组成
     一.界说
     狭义界说: 万能轧制钢材的机械设备。它使轧件在旋转的轧辊间发生塑性变形，轧出所需断面形状和尺度的钢材。即首要设备一一主机列。  (厚板、中板、薄板、轨梁、槽钢、角钢、螺纹钢筋、线材等)
     广义界说: 用于轧制钢材生产工艺悉数所需的首要设备和辅佐设备的成套机组。包含轧制，  运送、翻钢、冷却、剪切、矫直等设备。
     二.组成:  首要设备和辅佐设备
     1。首要设备: 主机列。包含作业机座(机架、轴承、调整设备、导卫)、传动设备(齿轮、减速机、连轴节) 和主电机。
     2。辅佐设备: 主机列之外的其它设备。车间的自动化程度越高，分量所占的份额越大。(是首要设备分量的3~4倍)(如鞍钢中型的半截美).

The definition and composition of universal steel rolling mills

一. Definition

Narrowly defined: Universal mechanical equipment for rolling steel. It causes the rolled piece to undergo plastic deformation between the rotating rolls, rolling out steel with the required 

cross-sectional shape and size. That is, the primary equipment - the host column. (Thick plates, medium plates, thin plates, rail beams, channel steel, Angle steel, threaded reinforcing bars, 

wire rods, etc.)

Broadly defined: A complete set of equipment and auxiliary equipment required for all the main and auxiliary equipment in the steel rolling production process. It includes equipment for rolling, 

transportation, steel flipping, cooling, shearing, straightening, etc.

二. Composition: Primary equipment and auxiliary equipment

1. Primary equipment: Mainframe column. It includes the working base (frame, bearings, adjustment equipment, guide guards), transmission equipment (gears, reducers, couplings) and main motor.

2.Auxiliary equipment: Other devices outside the main train. The higher the degree of automation in the workshop, the greater the share of weight it occupies. It is 3 to 4 times the weight of the 

primary equipment (such as half a piece of the medium-sized Ansteel).
