为了测定各种轧辊辊身表面的磨损状态,一般用卡钳、外径千分尺、游标卡尺等直接测定轧辊辊身部分的外径,或者用卷尺等测定轧辊辊身部分的周长,再计算出外径。但是,不管用那种方法进行测定,都很费时间。因此,要确定轧辊形状,沿着轧辊全长进行测定是很困难的。一般只测定几个有 In order to measure the wear state of various roll barrel surfaces, it is common to measure the outer diameter of the roll barrel portion directly with a caliper, micrometer, vernier caliper or the like, measure the perimeter of the roll barrel portion with a tape measure, and then calculate the outer diameter. However, no matter which method is used, it takes time. Therefore, to determine the shape of the roll, it is difficult to measure along the entire length of the roll. Generally only a few have been measured
