Description

(5). СПОСОБ ОЧИСТКИ ПОВЕРХНОСТИ полосы от ПЕЧНОЙ ОКАЛИНЫ(five). METHOD OF CLEANING OF THE SURFACE OF THE STRIP FROM THE HEATED SCALE

1one

Изобретенное относитс  к прокатному производству и может быть использовано дл  очистки поверхности гор чекатаной полосы от печной окалины в потоке стана.The invention relates to rolling production and can be used to clean the surface of a hot rolled strip from furnace scale in the mill stream.

Известен способ охлаждени  и очистки полосы от окалины, включающий пропускание полосы через встречно вра1щающиес  валки со щеточным покрытием и смыв окалины водой под давлением . в промежутках мехаду парами валков, причем струи воды подаютс  перпенди- . кул рно поверхности пр осы A known method of cooling and descaling the strip includes passing the strip through counter roll rolls with a brush coating and washing the scale with water under pressure. In the intervals of the mehada, there are pairs of rolls, with the water jets being perpendicular. cool surface of the wasp

Недостатком способа  вл етс  возможность неполного удалени  с гор чего проката печной окалины.The disadvantage of this method is the possibility of incomplete removal from hot rolled furnace scale.

Целью изобретени   вл етс  повышение эффективности удалени  окалины с поверхности полосы.The aim of the invention is to increase the efficiency of scale removal from the strip surface.

Поставленна  цель достигаетс  тем, что согласно способу очистки проката от окалины, включающему пропуск полосы через встречно вращающиес  по отношению к направлению движени  проката валки, установленные с раствором , равным толщине прокатами смыв окалины водой под давлением, струи воды подают перед ёходом проката в .валки в зону взрыхлени  окалины и направл ют их под углом 5-10 к поверхности проката в плоскости, перпендикул рной направлению движени  полосы.The goal is achieved by the fact that according to the method of cleaning the rolled metal from the scale, which includes passing the strip through rolls oppositely rotating with respect to the direction of movement of the rolled, mounted with a solution equal to the thickness of the rolled out washing of the scale with pressurized water, water jets are fed into the rolling mill the zone of loosening of the scale and direct them at an angle of 5-10 to the surface of the car in the plane perpendicular to the direction of movement of the strip.

Зазор между вал15 ками 3 двухвалковой клети устанавливают по номинальной толщине проката; При нагреве линейные размерь) -проката увеличиваютс  и в нагревательной печи на полосе образуетс  слой печ20 ной окалины. Вследствие этого зазор между валками оказываетс  меньи1е толщины нагретого проката, и валки, вращающиес  в сторону, противоположнуюLane 1, moving with acceleration across the roller table 2, accelerates and enters a two-roll stand with a spring-pressing mechanism. The gap between the rollers 15 kami 3 two-roll stand set at the nominal thickness of the car; When heated, the linear dimensions of the) -rolling increase and a kiln scale layer forms on the strip in the heating furnace. As a consequence, the gap between the rollers is less than the thickness of the heated rolled, and the rollers, rotating in the opposite direction
