Roll guide checking platform and checking method for finishing mill and pre-finishing mill

Abstract

The invention relates to the field of rolling mill roll-guide checking equipment and specifically relates to a roll guide checking platform for a finishing mill and a pre-finishing mill. The platform comprises a platform base and a lining bar ruler, wherein the lining bar ruler is disposed on the platform base; a ruler hole is formed in the lining bar ruler; and a lining bar can pass through the ruler hole. The invention provides the roll guide checking platform for the finishing mill and the pre-finishing mill as well as a checking method which applies the device to check a roll guide, wherein a variation amount based on bearing clearance generated after one revolution of a nut as well as a simulated condition, positioning of a hole pattern rolling center line of a guide wheel and adjustment of a clamping amount can be implemented accurately. In this way, roll guide assembly accuracy is guaranteed; a service life of the roll guide is prolonged; replacement frequency of the roll guide is reduced; production efficiency is increased; and technological stability in installation is also enhanced.

Description

technical field [0001] The invention relates to the field of rolling mill guide calibration equipment, in particular to a guide calibration platform for a finishing mill and a pre-finishing mill. Background technique [0002] The guide is an indispensable and important part of the section steel rolling equipment. It is generally installed on the rolling mill frame, before and after the roll pass. During the profile rolling process, the guide is mainly to guide and support the rolled piece to enter and exit the roll pass accurately and stably according to the established direction and state, reduce rolling failures, and ensure the safety of people and equipment. As one of the key equipment for profile rolling, whether the structure design, installation and use of guides are reasonable will directly affect the quality of rolled products and the production capacity of rolling mills. If the design or use of the guide device is improper, qualified products cannot be rolled out, ...
