Abstract

The invention relates to the technical field of rolling, and provides light rail profile steel rolling equipment and process based on the pre-bending cooling technology. The light rail profile steel rolling equipment comprises a guide device and a rough rolling device which are arranged on a rack in the conveying direction of a conveying device, wherein the guide device comprises third telescopic pieces, guide plates and guide rolling shafts, and the third telescopic pieces are arranged on the rack and positioned on the two sides of the conveying device; the guide plates are arranged at the telescopic ends of the third telescopic pieces, and the guide rolling shafts are rotationally arranged on the guide plates;the rough rolling mechanism comprises a first rough rolling device and a second rough rolling device; the first rough rolling device is arranged on the rack in a sliding mode and positioned on the rack in the conveying direction of the conveying device, and the second rough rolling device is arranged on the rack in a sliding mode and positioned at the bottom of the first rough rolling device; and the sliding direction of the first rough rolling device and the sliding direction of the second rough rolling device are perpendicular to the conveying direction of the conveying device. By means of the technical scheme, the problems that in the prior art, rough rolling is large in occupied area, and a guide structure is abraded are solved.

Description

technical field [0001] The invention relates to the technical field of rolling, in particular to a light rail section steel rolling equipment and process based on pre-bending cooling technology. Background technique [0002] The metal billet passes through the gap between a pair of rotating rolls (various shapes), and the cross-section of the material is reduced due to the compression of the rolls, and the pressure processing method increases the length. This is the most commonly used production method for steel production. It is mainly used to produce profiles, Plates, pipes. There are two types of hot rolling and cold rolling. The rolled piece is pulled into the rotating roll by friction, and is compressed and plastically deformed. Through rolling, the metal has a certain size, shape and performance. Rail steel is a professional section steel used to manufacture locomotives, cranes and other tracks. Light rail section steel belongs to rail steel. Light rail section steel ...
