当轧制其它型材时,可以用水平机架更换***机架。水平机架的轧辊有很深的孔型,而***机架没有。
较大直径的水平轧辊确定型钢的的形状,而较小直径的一对立辊用于轧制边部。当坯料穿过传统机架和***机架精轧轧辊时,可以获得很好的表面光洁度和尺寸公差。
When rolling other profiles,圣霖国际吊车轨, the universal rack can be replaced with a horizontal rack. The roll of the horizontal frame has a very deep pass, but the universal rack does not.
Horizontal rolls with larger diameters determine the shape of the section steel, and a pair of rolls with ***aller diameters are used for rolling edges. Good surface finish and dimensional tolerance can be obtained when the blank passes through the conventional stand and universal stand finish rolls.
通常对粗轧辊以强度、抗热裂为主要要求;小型20辊轧机的工作轧辊重仅 100克左右,而宽厚板轧机的支承辊重量已超过200吨。选用轧辊时首先根据轧机对轧辊的基本强度要求,选定安全承载的主体材料(各种级别的铸铁、铸钢或锻钢等)。
Usually, the main requirements for rough rolling roll are strength and thermal cracking. The working roll weight of ***all 20 high mill is only 100 grams, while the weight of backup roll of wide plate mill has exceeded 200 t***. When selecting the roll,圣霖国际吊车轨生产商, first, according to the requirements of the mill's basic strength for the roller, we select the main material for safety loading (various grades of cast iron, cast steel or forged steel, etc.).
这些应力沿辊身的散布是不均匀的、不断改变的,其原因不只有规划要素,圣霖国际吊车轨厂家,还有轧辊在运用中磨损、温度和辊形的不断改变。
The dispersion of these stresses along the roll is uneven and c***tantly changing, and the reas*** are not only the planning elements, but also the c***tant change of wear, temperature and roll shape in the use of the rolls.
