THE METHOD OF DIFFERENTIAL ACCOUNTING OF SPECIFIC CONSUMPTION OF ROLLS OF THIN-SHEET MILL DEPENDING ON THE LEVEL OF LOADING, AND THE DURATION OF THE OPERATION
The article considers the factors that determine the level of consumption of the active layer rolls of rolling mills. The analysis of the different methods of evaluation of speciﬁc consumption of rolls. The necessity of accounting the level of loading, and the duration of operation of the rolls in the assessment of their speciﬁc consumption. It is shown that the change in the level of loading of the roll is connected with the consistent of its exploitation in the various stands of continuous groups of the camp. The analysis of the level of loading of rolls with their exploitation in the stands of continuous hot strip mill, the estimated effect of the level of loading on the consumption values of the active layer, a method of accounting for speciﬁ c consumption of roll with the differentiation of working layers and the stands. The method of differential accounting of speciﬁc consumption of roll is suitable for various types of hot and cold rolling mills, to interchangeable rolls several of the camps.
