Calculation of fabrication coefficients in plate production

Together with this, specifications for plate production provide for some variation in the tolerance for side crop, depending on the dimensions of the slab and plate, amount of reduction in edging passes, mode of rolling, wear roll in the roughing and finishing stands, etc. For example, on the 2250 and 2800 mills at the Kommunarsk Metallurgical Plant, depending on the above-named parameters the tolerance for lateral crop is set at values ranging from 80 to 210 mm (with increments of 10-20 mm). In this connection, it has been proposed [K. N. Savranskii, K. N. Tkalich, Yu. V. Furman, et al., Plate production, Handbook [in Russian], Vol. 3, Metallurgiya, Moscow (1975), pp. 19-23] that the fabrication coefficient C be determined from the following equation:
