H-shaped steel rough rolling pinch guide device

Abstract

The invention discloses an H-shaped steel rough rolling pinch guide device, which comprises two left and right guide roller arms, and is characterized in that a guide roller is installed between the left and right guide roller arms, and the guide roller The left and right plate pinch guide plates are provided below the bottom of the guide roller, and the inner walls of the left and right guide roller arms are provided with a fixed plate. The fixed plate is provided with a plurality of strip holes. There are left and right plate pinch guide plates installed, and the angle between the two plate pinch guide plates can be adjusted by adjusting the position of the fastener. The side wall of the guide roller is provided with an H-shaped steel slot, and the clamp The bottom of the groove is provided with two semicircular magnetic rings which attract each other and fasten together. The semicircular magnetic rings are detachable. A rotating shaft is installed above the left and right guide roller arms. The side walls of the rotating shaft are provided with With descaling scraper. The invention overcomes the defect of low automation degree of guide roller cooling in the prior art, has good versatility, can adapt to the transportation of H-shaped steels of different sizes, and provides a temperature control system equipped with shape memory alloy parts, which has a high degree of automation , water saving and other characteristics.

Description

technical field [0001] The invention relates to the technical field of steel rolling, in particular to a pinch guide device for rough rolling of H-shaped steel. Background technique [0002] The guide rollers on the existing guides work for a long time due to contact and friction with the steel rolling, causing serious heating of the guide rollers. Continued contact friction will further accelerate the wear of the guide roller and reduce the service life of the guide roller. In the prior art, the method of spraying cold water on the guide roller is often used to cool it. This cooling method has a low degree of automation, cannot detect the real-time temperature of the guide roller, and is prone to waste water resources. [0003] In the prior art, different types of H-beams are prone to appear during the processing and conveying of H-beams. Due to different specifications and sizes, the conveying rollers of the H-beams need to be constantly replaced, which affects production...
