Modelling study of the elastic deformation for 4-h mill;

四辊轧机弹性变形解析模型的研究

This paper was to discuss the elastic deformation of rollers and interaction between work rollers and the strip during the roller milling process of a 4-h mill,by analyzing stress and deformation of rollers,put forwards a concise and practicable mathematic model of roller gap's shape,which resulted from some relevant factors,such as rolling pressure,bending force and so on.

针对轧制过程中轧辊的弹性变形和轧辊与轧件间的相互作用,通过对四辊轧机辊系变形和受力状况的分析,从理论上详细推导了直观的有载辊缝形状函数,明确了有载辊缝形状函数与相关因素的对应关系。

The axial overload is the main factor which causes work roll bearings and back up thrust bearings of four high mill invalid.

四辊轧机工作辊轴承及支承辊止推轴承失效的主要原因是轴向力过大。

The finite element method is used to solve the deflection of rolls for 4-high mill.

采用有限元方法求解四辊轧机辊系变形问题，由于在工作辊及支承辊之间存在着未知接触压力和位移因而该问题无法用简单方法求解；根据辊系变形与受力的特殊性对方程进行变换可解出辊系各点位移，从而实现对辊系变形及辊缝形状进行较为准确的预报及控制。

Influence of axial function at rolls in four-high mill upon the service life of roll bearing;

四辊轧机辊系间的轴向摩擦力对辊系轴承寿命的影响

For 2800mm 4-high mill, PMR (Plate Mill Backup Rolls with Variable Contact-Length), PWR (Plate Mill Work Rolls used for "deadflat" plate rolling) and a series of work roll contours configured for PMR are developed.

本文提出并建立了中厚板精轧机的工作辊与支持辊辊形解耦同步设计的理论和方法,依此创制出2800mm四辊轧机使用的变接触支持辊辊形(PMR)及配套的系列工作辊辊形和轧制超平材用的工作辊辊形(PWR),建立了相应的磨辊工艺制度。
