Abstract
PURPOSE: To prevent the generation of chattering, to improve the product quality, and to save the cost, by limiting the work roll diameter and the unit tension of the steel plate on the exit side of the high reduction cold rolling mill, to a special range, in case of cold rolling of the steel strip.
CONSTITUTION: The thick steel plate 11 of unusually large size is rolled into the product by the conventional method, through the storage 3, the high reduction rolling mill 4 (the work roll diameter is limited to 100W300mm for saving the power consumption), the tension adjuster 5, the pickling apparatus 7, etc. In above stated tension adjuster 5, the tension of the strip 13 on the exit side of the rolling mill 4 is required to be under 30 kg/mm2 and above the value calculated from the experimentally resulted formula σmin = (-0.025D + 0.25R + 8.75), in which σmin is the lower limit of the unit tension (kg/mm2), R is the draft percentage (%) of the mill 4, and D is the work roll diameter (mm), for preventing the generation of chattering. According to this method, the generation of chattering is prevented and the product quality is improved without increasing the power consumption.
