采用摆式轧制法的原因用一般轧机轧制时,带材是逐渐由厚轧薄的。要使难变形金属达到很大的压下量,则采用直径尽可能小的工作辊,但是,其结果会使工作辊的咬入条件变坏,并使工作辊的机械强度降低。人们曾用四辊轧机和行星轧机大部分地克服了这些缺点。用这类轧机轧制时压下率可达70～90％。但是,冷轧表面质量要求高的金属带材时,这类结构形式的轧机的使用范围也有一定的限制。例如,在行星轧机上,装在相对位置的工作辊必须
The reasons for the use of pendulum rolling method rolling with the average mill, the strip is gradually thicker and thinner. In order to achieve a great reduction of the amount of the hard-to-be-deformable metal, the work roll with the smallest possible diameter is used. However, as a result, the work roll is deteriorated in biting-in conditions and the mechanical strength of the work roll is lowered. Most of these shortcomings have been overcome with the use of four-roll mills and planetary mills. When rolling with these types of rolling reduction of up to 70 to 90%. However, when cold-rolling a metal strip having a high surface quality is required, the use range of such a structure type rolling mill is also limited. For example, in a planetary mill, a work roll mounted in a relative position must be used
