轧钢车间轧制费用的相当大的一部分用于购买和加工轧辊上。根据工厂资料,在大型轧钢机上轧制一吨钢材,轧辊的消耗(以卢布计算)占轧制费用的14%。由于轧材钢号和断面的不同,轧辊消耗在轧制总费用中所占的比重可能更大。但是,直到现在,还没有制定出足够可靠的方法来比较不同材料轧辊的使用寿命和计算它们的耐久性。这就使各厂采用型号繁多的钢和铸铁来制造轧钢 A significant portion of the rolling costs of the rolling shop is spent on the purchase and processing of rolls. According to the factory data, a ton of steel is rolled on a large rolling mill, which consumes 14% of the rolling cost (in rubles). Due to the different rolled steel grades and sections, roll consumption may account for a larger share of total rolling costs. However, until now, no reliable enough method has been developed to compare the service life of different material rolls and to calculate their durability. This allowed the mill to manufacture rolled steel using a large variety of steel and cast iron
