A rolling steel conveying tension rebuilding device

Abstract

The invention discloses a tension reconstruction device for rolling steel conveying, which comprises a rolling machine body, a roller transmission, a steel detector, a controller, an electric telescopic rod and a strong electromagnet. device, the side of the feeding and pressing device far away from the body of the rolling mill is provided with a conveying positioning device, and the side above the conveying and positioning device close to the feeding and pressing device is provided with a tail-end magnetic tractor. This kind of steel rolling conveying tension rebuilding device, The end of the raw material of the steel strip is attracted and fixed by a strong electromagnet, and the unwinding speed of the uncoiler is kept constant under the action of the friction force generated by the clamping force of the pressure plate on the unwinder, and the steel cable is controlled by the guide pulley. Conduct guidance, so that the steel cable and strong electromagnet will generate tension on the tail end of the steel strip material, thereby re-establishing a tension on the steel strip tail end to ensure the force balance at the steel strip tail end.

Description

technical field [0001] The invention relates to the technical field of steel rolling mills, in particular to a rolling steel conveying tension rebuilding device. Background technique [0002] Rolling is a plastic deformation process in which the cross-section is reduced, the shape is changed, the thickness is thinned and the length is increased by means of the pressure exerted by the roll. In addition to obtaining the ideal external shape and size, it can also make the structure and properties certain. improvement. Steel rolling is usually a press process that changes the shape of a steel ingot, billet or steel plate between rotating rolls. [0003] Among them, for the rolling process of strip steel, in the first rolling process, when the strip tail of the first pass is about to be rolled, the tail of the steel coil will be separated from the uncoiler. At this time, the entrance tension of the rolling mill is zero, so that The tail of the first pass loses tension, and the ...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a steel rolling conveying tension reconstruction device, which has the advantages of uniform stress on the tail of the steel strip, preventing drumming at the tail of the strip, and preventing deviation during the rolling process of the steel strip, and solves the problem of strip tension. The problem of tail drumming and waste of materials
