(54) СПОСОБ ПОДАЧИ ОХЛАДИТЕЛЯ НА ПОВЕРХНОСТИ ПРОКАТНЫХ ВАЛКОВ ЛИСТОВЫХ СТАНОВ(54) METHOD FOR SUPPLYING A COOLER ON THE SURFACE OF ROLLED ROLLS OF SHEET MILLS
1one
Изобретение относитс к прокатному производству .This invention relates to rolling production.
Известен способ подачи охлаждающей жидкости на поверхности валков листовых прокатных станов плоскими стру ми, оси которых расположены в плоскост х, параллельных оси валка, а направлени движени струй перпендикул рны оси валка.A known method of supplying coolant on the surface of the rolls of sheet rolling mills with flat streams, the axes of which are located in planes parallel to the axis of the roll, and the directions of movement of the jets are perpendicular to the axis of the roll.
Однако известный способ характеризуетс неравномерностью охлаждени поверхности валка, т. к. отдельные струи создают местное охлаждение валка. Неравномерность охлаждени вызывает по вление температурных напр жений в поверхностном слое валка. Иодача охлаждающей жидкости на валок сплощной плоской струей ведет к перерасходу охладител .However, the known method is characterized by uneven cooling of the roll surface, since individual jets create local cooling of the roll. Irregular cooling causes thermal stresses in the surface layer of the roll. Iodacha coolant on the roll flat flat jet leads to excessive cooling.
Цель изобретени - повышение равномерности раснределени охлаждени но поверхности бочки валка и снижение расхода охладител .The purpose of the invention is to increase the uniformity of the cooling distribution over the surface of the roll barrel and reduce the coolant flow rate.
Дл этого охладитель нодают на валок с направлением движени струй под острым углом , например 30° к оси валка.For this, a cooler is installed on a roller with a direction of movement of the jets at an acute angle, for example 30 ° to the axis of the roller.
На фиг. 1 показана часть развернутой поверхности валка со схематичным изображением струй; на фиг. 2 - вид сбоку на валки с устройством дл их охлаждени .FIG. 1 shows a portion of the unfolded surface of a roll with a schematic representation of the jets; in fig. 2 shows a side view of the rolls with a device for cooling them.
На поверхности валка 1 струи 2 растекаютс под острым углом ос к оси валка, что обеспечивает перекрытие ими всей поверхности валка и отсутствие кольцевых участков, имеющих перепад температур. ОхлаждениеOn the surface of the roll 1, the jet 2 spreads at an acute angle of the axis of the roll axis, which ensures the overlapping of the entire surface of the roll and the absence of annular sections having temperature differences. Cooling
предлагаемым-способом может быть реализовано посредством форсунок 3 со щелевыми отверсти ми, направл ющими плоские струи 4 охладител на валки 5.the proposed method can be implemented by means of nozzles 3 with slotted openings directing the flat jets 4 of the cooler to the rolls 5.
