Abstract

Изобретение относитс к прокатному производству и может быть использовано при производстве полосового проката на широкополосных станах гор чей прокатки. Цель изобретени - снижение простоев стана при его работе в режиме контролируемой прокатки за счет использовани бокового рольганга дл охлаждени подката, а также устранение провисани подката при перемещении с бокового рольганга на промежуточный. Подкат дл его охлаждени сбрасывателем 3 перемещаетс на боковой рольганг 2 и транспортируетс в зону сбрасывател 4, где происходит его естественное охлаждение. Следующий подкат сбрасывателем 3 смещаетс на боковой рольганг, а после выхода третьего подката первый из поступивших на боковой рольганг возвращаетс на промежуточный рольганг 1. При перемещении подката штанги сбрасывател совместно с тележками 7 выдвигаютс в сторону бокового рольганга, подъемные балки, поднима сь по копирам, поднимают тележки и роликовые дорожки, которые осуществл ют съем подката с роликов бокового рольганга и подъем выше роликов промежуточного рольганга. Штанги сбрасывател , возвраща сь в исходное положение, посредством т г перемещают тележки и возвращают подкат на промежуточный рольганг. Это позвол ет сократить паузы при прокатке с подстуживанием. 2 з.п. ф-лы, 3 ил.The invention relates to rolling production and can be used in the production of strip rolled on wide strip mills for hot rolling. The purpose of the invention is to reduce mill downtime during its operation in controlled rolling mode by using a side roll table to cool the rolled stock, and also to eliminate the roll back sag when moving from the side roll table to the intermediate one. The tackle for cooling with the ejector 3 is moved to the side roller table 2 and transported to the zone of the ejector 4, where its natural cooling takes place. The next tackle by the ejector 3 is shifted to the side roller conveyor, and after the third tackle has come out, the first one arriving at the side roller table returns to the intermediate roller table 1. When moving the rolled bar, the dumper together with the trolleys 7 move towards the side roller table, the lifting beams lift the copiers and lift trolleys and roller tracks that remove the rolled stock from the rollers of the side roller table and rise above the rollers of the intermediate roller table. The rods of the resetter, returning to the initial position, move the carts by means of t g and return the tackle to the intermediate roller table. This makes it possible to shorten the pauses when rolling with pushing. 2 hp f-ly, 3 ill.

Claims

Claim

1. A device for the lateral movement of the rolling stock in the flow of the rolling mill, including an intermediate and side roller tables located parallel to each other and at different levels, a rolling stripper with pushing rods and a drive for moving them, gas cutting units located along the side rolling table, characterized in that that, in order to reduce the downtime of the mill during its operation in a controlled rolling mode through the use of a side roller table to cool the tackle, each bar is equipped with a trolley hydrochloric beam on and kinematically connected to the rod by a lateral roller conveyor and the drive of lifting-lowering of the beam while the carts 5 are mounted between the rollers and the side of the intermediate roller table.

2. The device according to π. 1, characterized in that, in order to eliminate sagging of the liner 10 when moving from the side roller table to the intermediate one, it is equipped with additional supports in the form of roller tracks mounted on their own beams connected to the mechanism for raising and lowering them, while roller tracks with ¹⁵ beams are installed in the gaps between the trolleys and the rollers of the side roller table.

3. The device according to π. 1, characterized in that each of the lifting-lowering mechanism of the beams is made in the form of a copier and a hydraulic cylinder connected to the beam.
