机架是轧钢机的主要部件，它在轧钢过程中承担金属变形给予的负荷。因此要求机架有足够的强度和刚度，520轧机哪家好，以保证设备安全和产品质量。型钢轧机的机架形式较多，常见的机架形式有开口式机架、闭口式机架和半闭口式机架3种。
The frame is the main component of the rolling mill， which bearsthe load given by the metal deformation during the rolling process.Therefore，520型号轧机， the frame is required to have sufficientstrength and stiffness to ensure the safety of the e andthe of the product. There are more frame forms of the steelmill. There are 3 kinds of common frame forms: open frame， closedframe and half closed frame.
在锻造和轧制生产中，钢坯一般在完全燃烧火焰的氧化气氛中加热。采用不完全燃烧的还原性火焰（即“自身保护气氛”）来直接加热金属，可以达到无氧化或少氧化的目的。这种加热方式称为明火式或敞焰式无氧化加热，成功地应用于转底式加热炉和室式加热炉。
In forging and rolling production， billets are usually heated inthe combustion atmosphere of complete combustion flame. The directcombustion of metal can be achieved by the incomplete combustion ofreduced flame (i.e.， the "self protective atmosphere")， which canachieve the of no oxidation or less oxidation. This heatingmethod is called open flame or open flame oxidation free heating，which has been successfully applied to rotary hearth furnace andchamber heating furnace.
保持工作辊的上辊和下辊相对于轧机中心线对称且在轴线方向上移动。这种的工作辊移动的设计，520轧机，是用来改变工作辊和支撑辊的偏移需要大的移动量。这种大移动量的采用需要大量的改装费用，并且需要解决很多问题.
The upper and lower rolls of the work roll are symmetrical andmove in the direction of the axis of the rolling mill. The movementof this work roll is designed to change the shift of work rolls andsupport rolls to require large amounts of movement. The use of thislarge shift of momentum requires a lot of modification costs， andmany problems need to be solved.
