METHOD OF STRIPS HOT ROLLING Russian patent published in 1995 - IPC

FIELD: hot rolling. SUBSTANCE: method of strips hot rolling provides for strips rolling by rolling mill with simultaneous adjustment of their flatness, strips cooling by water from above and from below on removing roller conveyer and continuous measurement and record of temperature of strip winding, presented as diagram. In the case strips flatness deviations control is exercised after their cooling by presence in recorded diagram of high frequency component of winding temperature differences. Value of deviations is determined by amplitude of the deviations. In the case, to decrease amplitude of high frequency component of winding temperature differences ratio of consumption of fed cooling water from below over water consumption from above is increased. EFFECT: method provides high degree of flatness of strips in process of their hot rolling by rolling mill. 4 dwg, 1 tbl
