Description

Изобретение относитс  к прокатно .му производству и может быть использовано дл  охлаждени  в линии, стана полосового проката, преи.мущественно движущегос  по рольгангу со скоростью до 3 м/с. Известно устройство дл  охлаждени  проката, включак дее полые оси с щелевыми отверсти гл, служащие водона-:порными баками, и вращанвдиес  на них цилиндрические корпусы ш.еток, вэаимодействукщие с охлаждаемой полосой. В процессе охлаждени  полосы через отверсти  в междур дь х щеток она взаимодействует одновременно со щеткгьми разбивающими образующуюс  на полосе при соприкосновении с охладителем паровую рубашку f . Недостатком известного устройства  вл етс  то, что в промежутках между meTKaivM, равных по меньшей мере диаметру щеток, отсутствует возкюжность взаимодействи  щеток с полосой и соответственно на этих участках полосы происходит восстановление паровой рубашки, что увеличивает непроизводительный расход охладител  и уменьшает интенсивность охлаждени . С целью повыиени  интенсивности охлаждени , снижени  расхода охладител  и упрощени  устройства щеточные устройства выполнены в виде разь«щенных .между водонапорный баками секций , которые набраны из щеток, образующих плоскую рабочую поверхность, причем ширина секций равна ширине полосы, а длина превышает их ширину в 1,2-2,0 раза. Плоские щеточные секции размещены с минимальны.и проме сутками между ними,необходимыми и достаточными дл  прохождени  плоской стенки ламинарных струй охладител  на- полосу. Это практически исключает участки, на которых отсутствует воздействие щеток и может иметь место образование паровой рубашки на полосе. Благодар  этому уменьшаетс  расход охладител , увеличиваетс  интенсивность охлаждени  полосы и упрощаетс  конструкци  устройства. На чертеже представлено предлагаемое устройство. Водонапорные баки 1 со щелевыми соплами 2 устанавливаютс  вдоЛь рольганга с движущейс  охлаждаемой полосой 3. В промежутках между расположены секции 4 с набранными в них проволочными щетками 5. Щеточные секции регулируютс  по высотеThe invention relates to rolling production and can be used for cooling in a line, a strip mill, mainly moving along the roller table at a speed of up to 3 m / s. A device for cooling rolled products is known, including hollow axles with slit holes of the head, serving as water tanks: porous tanks, and cylindrical shear-type housings, which are self-acting with a cooled strip, rotate on them. In the process of cooling the strip through the openings between the brushes, it interacts simultaneously with the splitting brushes that form on the strip, in contact with the cooler, the steam jacket f. A disadvantage of the known device is that in the intervals between meTKaivM equal to at least the diameter of the brushes, there is no interaction between the brushes and the strip, and accordingly the steam jacket is restored in these sections of the strip, which increases the cooling overhead and reduces the cooling intensity. In order to increase the cooling intensity, reduce the flow rate of the cooler and simplify the device, the brush devices are made in the form of sections between brushes forming a flat work surface, the width of the sections being equal to the width of the strip and the length exceeding their width 1 , 2-2.0 times. The flat brush sections are placed with minimal and spaced days between them, necessary and sufficient for the flat wall of the laminar jets of the cooler to pass to the strip. This virtually eliminates areas where there is no brush exposure and the formation of a steam jacket on the strip may occur. This reduces the flow rate of the cooler, increases the intensity of the cooling strip and simplifies the design of the device. The drawing shows the proposed device. Water tanks 1 with slit nozzles 2 are installed at the end of the roller table with a moving cooled strip 3. In the intervals between sections 4 are located with wire brushes 5 assembled in them. Brush sections are height adjustable
