ABSTRACT
Modern at rolling process tends to produce hot-rolled steel strips 0.8-1.5 mm thick, which had been previously attributed to the range of cold-rolling mills.
Most operating wide-strip, hot-rolling mills were designed to produce strips as thin as 1.8-2.0 mm, and their energyforce parameters (the roll force and the main drive engine power) are not intended for the rolling of thinner strips, which is characterized by higher reductions and contact stresses acting on rolls, complicated thermal conditions for the rolls because of an increase in the machine time in a rolling cycle, and (as a consequence) more intense roll wear.
