Finished product gathering guide groove for multi-line slitting rolling

Abstract

The invention discloses a finished product gathering guide groove for multi-line slitting rolling, and relates to the field of steel rolling in the iron and steel industry. The finished product gathering guide groove for multi-line slitting rolling comprises bottom plates, wherein side plates and guide wedges are arranged on the outer surfaces of the upper ends of the bottom plates; the side plates are located on the two sides of the guide wedges; a cover plate is arranged on the outer surface of the upper end of each side plate; the outer surfaces of the upper ends of the bottom plates are connected with the outer surfaces of the lower ends of the side plates in a welded mode; and the two groups of bottom plates are arranged. According to the finished product gathering guide groove for multi-line slitting rolling provided by the invention, by adopting the guide groove, gathering of finished products in the multi-line slitting rolling process can be stably achieved, so that the abnormal phenomena of line crossing, winding and the like in the process that the finished products are gathered into a double-length shear are avoided, the production condition from the finished product pass to the double-length shear is further stabilized, meanwhile, the service life of related facilities is prolonged, production accidents caused by deviation of finished product gathering are effectively avoided, and the use effect is better compared with a traditional mode.

Description

Technical field [0001] The present invention relates to the field of steel rolling steel, and more particularly to a multi-line-cutly rolled finished product gathering guide. Background technique [0002] Separating rolling means that a rolled metal is cut into two (or more) rolled members along the longitudinal direction on the steel rolling mill, and then rolled two (or more) finished rolling. The rolling process of the material, the center of the finished product is generally 135mm, because the multiplier shear width is limited (usually only 120-160mm wide), such two (or more) finished products are cut in a double-tier cutting It is necessary to "close together", otherwise a certain root (or more) finished product cannot be cut, which causes the production failure of the lower process, so, in the divided rolling product, the second There will be a finished product "gathering guide". [0003] The traditional gathering guide generally has only one bottom plate, two side plates, ...

AI Technical Summary

Problems solved by technology

[0004] The guide trough is a frame structure, and there is no channel for a single finished product to travel alone inside. There is only one channel, and the finished products of each line are prone to "fighting" during operation;

[0005] The angle between the side plate and the rolling center line is too large, generally more than 10°, that is, the convergence angle is too large, which leads to the rapid closing of the guide groove. On the one hand, the finished steel bars on both sides are prone to crossing and "winding" during the process of travel. and other defects; on the other hand, it will also increase the wear of the steel plates on both sides;

[0006] The material of the guide groove steel plate is ordinary Q235 material, which has poor wear resistance, and the side plate itself is thin (only 10-16mm), which is prone to side plate wear-through events;

[0007] The upper cover plate of the guide trough and the two side plates are fixedly connected by welding, which is not convenient for opening the guide trough for inspection and troubleshooting
