Steel rolling conveying tension rebuilding device

Abstract

The invention discloses a rolled steel conveying tension rebuilding device. The rolled steel conveying tension rebuilding device comprises a rolling machine body, a roller conveyor, a steel detector, a controller, an electric telescopic rod and strong electromagnets, wherein a feeding pressing device is arranged at one side of the rolling machine body, a conveying positioning device is arranged at the side, away from the rolling machine body, of the feeding pressing device, and a tail end magnetic tractor is arranged at the side, close to the feeding pressing device, above the conveying positioning device. According to the steel rolling conveying tension rebuilding device, the tail end of a steel belt raw material is attracted and fixed through the strong electromagnets, and under the action of friction force generated by the clamping force of pressurizing discs on unreeling machines, the pay-off speed of the unreeling machines is kept constant; and steel cables are guided through guide pulleys, so that tension is generated on the tail end of the steel belt raw material through the steel cables and the strong electromagnets, tension is rebuilt on the tail end of a steel belt, and the stress balance of the tail end of the steel belt is ensured.

Description

Technical field [0001] The present invention relates to the technical field of rolling mills, and is specifically a rolling conveying tension reconstruction device. Background technique [0002] The rolling is a plastic deformation process that is reduced by means of a roll, which is reduced, the shape change, and the thickness is increased, and the length increases, in addition to obtaining the ideal external shape and size, the tissue and performance can be obtained. Improvement. Among them, the rolling steel is typically a pressure processing process that changes the shape of the steel ingot, the steel blank or the steel sheet between the rotating rolls. [0003] Among them, for the rolling process of the steel, during the first rolling process, the first second end is completed, the steel rolling end is detached from the open machine. At this time, the inlet tension of the mill is zero, so that The first secondary tail will not be controlled by the tail of the steel, which wi...
