Existing method of runout table drive control on the hot strip mill ensures the required strip tension by setting a difference between speeds of the delivered strip and roller bodies. Such difference results in a higher wear rate of roller bodies and their more frequent replacement, entailing high expenses. Thus, a currently important objective is to increase efficiency of runout table ...
