Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of powder metallurgy, in particular to a guide chute protection device for a thick plate rolling mill. Background Art
[0002] In the production process of the wide and thick plate mill, the guide is a very important component. The function of the guide is to guide the billet through the rolling mill to ensure its position and direction during the rolling process. Therefore, the accuracy and reliability of the guide also have an important impact on product quality and production efficiency.
[0003] During rolling mill production, the steel plate is subjected to scraping and impact from the head of the steel plate during the process of importing and exporting, so as not to be separated from the working roll guard plate. The guide will move up and down frequently. The mechanism of this up and down movement is composed of components such as slide plates and slide grooves. Due to the harsh production environment of the rolling mill and poor working conditions, for example, when the high-pressure water dephosphorization equipment of the fuselage is working, the iron oxide scale on the steel plate will splash everywhere. If foreign objects such as iron oxide scale enter the slide groove of the slide plate, it will cause jamming and increased wear, thereby reducing the accuracy of the equipment. Therefore, it is necessary to manage and maintain the equipment in a refined manner, and take corresponding measures to prevent jamming and reduce the occurrence of problems such as slide wear to ensure its normal operation.
