Description
(54) СГЮСОБ РЕГУЛИРОВАНИЯ ТЕМПЕРАТУРЫ КОНЦА ПРОКАТКИ ПО ДЛИНЕ РАСКАТА(54) REGULATION REGULATION TREATMENT AGAINST ROLLING FOR ROLL-TERM LENGTH
II
Изобретение огноситс к прокатному щюизводсгву, конкретно к регулированию температуры конца прокатки в чистовой группе широкополосного стана. The invention is fire-rolling, specifically for controlling the temperature of the end of rolling in the finishing group of a wide-strip mill.
Изеестен способ регулировани температуры конца гор чей прокатки путем измеаеа теплоойулена между нагретым прокатом и рабочими валками Ll-3Недостатками данного способа вл етс низка эффективность, ин ционность, привод щие к н авномерному распределению температуры по длине проката, вследствие чего по вл етс анизотропи физикомеханических свойств.The method of adjusting the temperature of the end of hot rolling is measured by changing the heat-coil between the heated rolling stock and the work rolls Ll-3. The disadvantages of this method are low efficiency and ingenuity leading to a uniform temperature distribution along the rolling length, resulting in anisotropy of physical properties.
Наиболее близким к предлагаемому по технической сущности вл етс способ регулщювани температуры конца гор чей прокатки, в котором последовательно по ходу прокатки в чистовой группе широкополосного стана на поверхности рабочих валков нанос т теплоизол ционное покрытие с изменением его толщины от первой клети к последней 23.The closest to the proposed technical essence is a method for controlling the temperature of the end of hot rolling, in which a heat insulating coating is applied successively along the rolling surface of the broadband mill to the surface of the work rolls with a change in its thickness from the first stand to the last 23.
Недостаток известного способа зактпочаетс в том, что из-за малого диапазона воаможеюсти регулировани толщины покрыти грур о обеспечить равномерное распределение темп атуры по ее длине.The disadvantage of this method is that in the fact that, due to the small range of the ability to adjust the thickness of the coating of the group, it is possible to ensure uniform distribution of the atura rate along its length.
Целью изофетени вл етс повыше кие эффективности регулировани температуры по длине раската.The goal of izofeteniya is to increase the efficiency of temperature control along the length of the roll.
Поста1вл ша цель достигаетс тем, что согласно способу рогулированн температуры конца прокатки с эмеа&вивм теплообмена между нагретым раскатом и рабочими валками, заключающемс в последовательной по ходу прокатки подаче на поверхность рабочих валков теллоиэол шгонного покрыти , указанную операцию в каждой последующей клети осуществл -. ют с регламент1фуемым временным интервалом , определ емым по следующей зависимостиThe purpose of this goal is achieved by the fact that according to the method of roving the temperature of the end of rolling with emea & vivm of heat exchange between the heated bar and working rolls, which is consistently rolling along the surface of the work rolls, tellurium ethanol chamfer coating is carried out. with the regulation 1 time interval defined by the following dependence
Т T
где Т - продолжительность интервалаwhere T is the duration of the interval
