Description

Field of application of the invention

The invention relates to a device for stripping rolling stock from the work roll during rolling of metallic materials on metallurgical rolling stands.

Characteristic of the known technical solutions According to the state of the art, a device for stripping the rolling stock from the work rolls is known, which in shape

a drive-in table is movably arranged in front of the Arbritswalzen. The actual scraper is mounted on the roller side facing the table. Such an entry table has only tension rollers, no valve rollers and represents the state of the art for cold rolling mills.

The disadvantage of the solution described lies in the fact that for assembly and disassembly of Walzgutabstreifers the

entire entrance table must be moved out of the rolling mill to achieve the necessary freedom of assembly. For

Hot rolling mills, this design is completely unsuitable. Furthermore, a solution for hot rolling stands is known, which is characterized in that a stripper plate to the Supported chocks of the roller and in which a roll bar between the chocks in the rolling stand in front of and behind the Work roll is mounted. On the rolling beam are as individual parts to the valve wheels with storage and a Abstreiferplatte to

assemble.

This solution has the disadvantages that only a single assembly of the components in the roll stand is possible, a Adjustment of the scraper plate when rolling wear or abrasion missing and difficult conditions for the Maintaining the functionality are given. Furthermore, an apparatus for the continuous descaling of rolling stock is known in which the rolling beams like a chamber

are formed, are arranged below and above the roll gap nozzles and Walzgutabstreifer on the rollers facing side mounted on the device (DE-OS 3624794).

The built-in spray nozzles serve the Walzgutentzunderung. The entire device is between the pillars of the columns Roller stand attached. Dib disadvantages of this solution are analogous to those already described in the rolling bars for hot rolling mills

were.

Finally, the state of the art of rolling stands, that the rolling beam with fitting roller and Walzgutabstreiferplatte

as ülno joint unit is executed, which is to be mounted or dismantled in the rolling stand.

The need for Montagearboiten in the rolling mill proves to be the biggest disadvantage. Object of the invention

The aim of the invention is to provide optimal conditions for the assembly and disassembly of the roll installation including the Walzgutabstreifers with secure rolling stock.

Explanation of the weather of the invention

The invention is based on the task to develop a device for stripping of rolling stock, walche.unter particular attention to the ease of maintenance a safe and adjustable height Spiel dos rolling mill allows, operates separately from the spray bar and allows the entire scraper system when changing rolls without loosening screws cutting and uncomplicated from the mill stand is removable.

According to the invention, the object is achieved in that symmetrically in front of and behind a roll a movably formed roll bar, consisting of a Abstreiferbalkenobertoil, a Abstreiferbalkenunterteil, a fitting roll, a Abstreiferplatte and a fitting, is arranged, wherein the fitting and a chock formed by means of a retaining screw lockable are.

The invention will be explained in more detail below using an exemplary embodiment. In the accompanying drawings shows

Fig. 1: a section of the device according to the invention Fig. 2: an arrangement of the rolling mill in plan view 3 shows a section B-B of Figure 4 and 4 shows a section A-A of Figure 2. The Ausfuhrlingsbeispiel extends to the inventive device for rolling aluminum and Aluminum alloy ingots to hot strip on a 8SO duo hot rolling stand and used for safe stripping of the Rolled material from the lower roller and its guide to the working roller table. As can be seen from the drawings, the

Device according to the invention arranged on a roller 1, that a Abstreiferbaikenoberteii 3 rests with the Abstreiferplatten 6 close to the rolling beam. A Armaturroüe 5 is arranged in the Abstreiferbaikenoberteii 3 so that it protrudes only slightly from the Abstreiferplatten β.

The Abstreiferbaikenoberteiiii 3 forms a spray bar 9 towards a smooth surface with sufficient distance to a

To ensure trouble-free removal and installation with the set of rollers. This part is on the

Abstreiferbalkenunterteil 4 attached, which finds its ends in the chocks 11 support. The fitting roller S and a stator roller 7 are arranged at the same height level. The spray nozzles 7 are in Spray bar 9 set up so that their KOhlmittelsti ahl both the rolling stock and the roller 1 before and behind or under the Armaturrolle 5 reached. The spray bar 9 is mounted in Walzenmständer and executed separately from the rolling beam. in the Rolled bars are incorporated openings for the passage of the coolant spray jets. The diameter or height deviation of the roll 1, which occurs as a result of roll grinding and other influences, passes through Fitted pieces 8, which are fastened with retaining screws 10 in the chocks 11. At the same time a maintenance-friendly a device according to the invention is achieved in a special way, without loosening of Screws the lateral retraction of Walzenoinbaues with the fitting rollers S and the Abstreiferplatten 6 allows.
