Изобретение относитс к области металлургии непрерывного лить и предназначено дл применени в устройствах системы вторичного охлаждени машины непрерывного лить .The invention relates to the field of metallurgy continuous casting and is intended for use in devices of the secondary cooling system of a continuous casting machine.
Известно иоддерживающее устройство системы вторнчиого охлаждени машины непрерывного лить , содержаш,ее верхние и нижние рамы с роликовыми секци ми, расположенными по разные стороны технологической оси устройства. При этом ролики снабжены регулируемыми амортизаторами и установлены с возможностью скольжени в направл юш,их, перпендикул рных технологической оси устройства 1.It is known that the supporting device of the system of the second cooling of the machine for continuous casting, containing its upper and lower frames with roller sections located on opposite sides of the technological axis of the device. In this case, the rollers are provided with adjustable shock absorbers and are installed with the possibility of sliding in the direction of their, perpendicular to the technological axis of the device 1.
Недостатком известного устройства вл етс то, что при прорыве металла под кристаллизатором заливины охватывают ролики и подвижности их в перпендикул рном относительно технологической оси направлении уже недостаточно, и ролики выход т из стро изза нагрузок, направленных вдоль технологической оси и превосход щих расчетные нагрузки . Выход роликов из стро происходит еш,е и потому, что при остановке слитка (в случае прорыва) он заклиниваетс и, охлажда сь , дает усадку.A disadvantage of the known device is that when a metal bursts under the mold, the castings cover the rollers and their mobility in a direction perpendicular to the technological axis is not enough, and the rollers fail because of the loads directed along the technological axis and exceeding the design loads. The exit of the rollers from the system is eh, e and because when the ingot is stopped (in case of a breakthrough), it gets stuck and, cooling, shrinks.
Целью изобретени вл етс повышение надежности поддерживаюи его устройства системы вторичного охлаждени .The aim of the invention is to increase the reliability of the support of its device of the secondary cooling system.
Это достигаетс тем, что в поддерживаюш ,ем устройстве системы вторичного охлаждени , содержащем верхние и нижние рамы с роликовыми секци ми, расположенными поThis is achieved by the fact that in supporting the device of the secondary cooling system, comprising upper and lower frames with roller sections located along
разные стороны технологической оси устройства , верхние рамы установлены на нижних посредством упругих элементов и снабжены направл ющими, обеспечивающими удержание их по технологической оси устройства.different sides of the technological axis of the device, the upper frames are mounted on the lower ones by means of elastic elements and provided with guides ensuring their retention along the technological axis of the device.
Па чертеже изображено предлагаемое устройство , общий вид.Pa drawing shows the proposed device, the overall appearance.
Устройство включает верхние 1 и нижние 2 рамы с роликовыми секци ми 3. Верхние рамы 1 установлены на нижних рамах 2 посредством упругих элементов 4 (например, амортизаторов ) и снабжены направл ющими 5. Роликовые секции 3 имеют ролики 6 с амортизаторами 7.The device includes the upper 1 and lower 2 frames with roller sections 3. The upper frames 1 are installed on the lower frames 2 by means of elastic elements 4 (for example, shock absorbers) and are equipped with guides 5. The roller sections 3 have rollers 6 with shock absorbers 7.
Работа устройства осуществл етс следующим образом.The operation of the device is as follows.
При помощи т нущих клетей (на чертеже не показаны) слиток 8 выт гивают из зоны вторичного охлаждени . При разрыве коркиWith the help of drawing stands (not shown in the drawing), the ingot 8 is pulled out from the secondary cooling zone. When breaking the peel
слитка и заливе жидким металлом роликов 6 секций 3 верхн рама 1 смещаетс в процессе усадки слитка к нижней раме 2 за счет иодвижных упругих элементов 4 и направл ющей 5, исключа , тем самым, поломку роликов 6.the ingot and the casting of the metal rolls 6 sections 3, the upper frame 1 is displaced in the process of shrinking the ingot to the lower frame 2 due to iodine elastic elements 4 and the guide 5, eliminating thereby the breakage of the rollers 6.
Величина хода упругих элементов 4 должна быть не менее величины усадки слитка при его остывании в период остановки машины .The stroke of the elastic elements 4 must not be less than the size of the shrinkage of the ingot when it cools down during the period when the machine stops.
