CVC系统功能说明在研究满足要求的调节机理之后,开发了CVC系统,如图13所示。CVC是“Continuou-sly Variable Crown”(连续改变凸度)的缩写。上下工作辊磨成S型。上下轧辊的磨削相同,但呈180°交错布置,从而使上下轧辊构成的辊缝形状呈对称形。当两个轧辊在相反方向作轴向移动时,辊缝形状就产生变化,呈现类似负或正轧辊凸度的效果。由于移动是无级的,故有连续改变轧辊凸度的效果。这项新技术的特点是:由于磨成S型,直径差别小,工作辊和支承辊之间的弹性变形就能使其接触完
CVC System Functional Description After studying the regulatory mechanism to meet the requirements, CVC system was developed, as shown in Figure 13. CVC is an abbreviation for “Continuously Variable Crown.” Up and down work roll mill into S-type. The upper and lower rolls were ground identically but 180 ° staggered so that the shape of the nip formed by the upper and lower rolls was symmetrical. As the two rolls are moved axially in the opposite direction, the shape of the roll gap changes, exhibiting effects similar to the negative or positive roll crown. As the move is infinite, it has the effect of continuous changes in roll crown. The new technology is characterized by: due to ground into S-type, the diameter difference is small, the work roll and roll between the elastic deformation can make contact
