SU1378960A1 - Method of rolling strips - Google Patents

Abstract

The invention relates to the processing of metals by pressure and can be used in the rolling of strips. The purpose of the invention is to simplify the setting, regulation and control of the rolling process. According to the invention, the strip is rolled in several deformation zones, which are formed by a fixed central deforming element and drive rollers located around it. In this case, the tape rolls over the center element and is not in contact with it between the deformation zones. The simplification of the adjustment, control and adjustment process is that it can be carried out sequentially in each deformation zone. In this case, the tuning effect in a given deformation zone affects the adjacent one only through the tension of the strip. 1 il. (L

The invention relates to the processing of metals by pressure and can be used in the rolling of belts.

The purpose of the invention is to simplify the adjustment, regulation and control of the rolling process.

The drawing shows a diagram of the rolling process.

Before rolling, the required initial gaps between the drive rolls 1 and the deforming surfaces 2 of the central deforming element 3 are set. The tape is tucked in

4 into the crate so that it covers the fixed element. The tape is rolled in several foci of deformation, while the strip between them does not come into contact with element 3. Rollers 5 and 6 serve to direct the PO / 1OSY into and out of the cage.

The simplification of the adjustment, control and adjustment process in comparison with the known method consists in the fact that it can be carried out sequentially in each deformation zone when the front end of the strip enters it. In this case, the tuning effect in a given deformation zone affects the

It has a smaller thickness and a better shape. Folding the tape in stable speed conditions becomes less likely.

Primer p. A tape of 08kp steel with a thickness of 0.5 mm and a width of 100 mm was rolled into a cage with six deformation points. The diameter of the work rolls is 100 mm gDiameter of the deforming surface of the fixed element 40 mm. The total compression was 80%. Crimp on deformation areas 18.00; 19.51; 24.24; 28.00; 27.78 and 23.07%. The speed of the metal from the last deformation zone is 1 m / s. Tensions were maintained at 0.1-0.15 in terms of yield strength.

The use of the proposed method allows to significantly stabilize the rolling process, which contributes to improving the quality of the produced tape.

Invention Formula The method of rolling tapes, including the simultaneous deformation of the strip in the previous one is only through tension in several foci of deformation between common central deforming element and drive rollers arranged around it, covering the central deforming element, characterized in that, in order to simplify adjustment, regulation and control of the rolling process, rolling is carried out at a fixed central element in the absence of contact of the strip with this the element between the foci of deformation. loses The established rolling process according to the proposed method is distinguished by stability, greater efficiency of possible regulatory influences, since there is no harmful interaction of the parameters of all deformation foci through the central deforming element characteristic of the known method. As a result, the quality of the rolled metal produced is higher - of a few heaps of deformation between a common central deforming element and drive rollers arranged around it, covering the central deforming element, characterized in that, in order to simplify adjustment, adjustment and control of the rolling process, rolling is carried out with a fixed central element in the absence of contact of the strip with this element between the deformation sites .
