Problems solved by technology

The traditional online repair method is to use soil equipment to disassemble the rolling mill to expose the bottom plate, drag the machine tool into place with the help of roller bars and manual drag chains, and move it to the processing part. The diameter of the cutter head is small, the cutting efficiency is low, and the installation is in place. The time is long, and the precision of multiple alignment is low

Abstract

The invention relates to an efficient method for repairing rolling mill arches on-line. The installation method of the method is advanced, simple and easy to implement, and the machine tool can be adjusted in advance without stopping the machine, thereby saving the time of online adjustment. The machine tool has a unique positioning method, and the installation reference is the roller changing track, with high precision. It can be directly fed into the predetermined position by the roller changing trolley, without the need for the traditional roller bar and reverse chain to be imported many times. High safety, high degree of mechanization, low labor intensity. The on-site dismantling quantity is small, the installation quantity is small, saving time and reducing the labor intensity of the project. Aligning and processing two planes at one time, high processing accuracy, parallelism not more than 0.03mm, and 360-degree indexable cutting, flexible and convenient.

Description

technical field [0001] The invention relates to an online repair method for a rolling mill archway, in particular to a movable boring and milling machine for an efficient method for online repairing a rolling mill archway. Background technique [0002] The rolling mill arch, also known as the rolling mill frame, is an important bearing part in the rolling equipment, and the working environment is very harsh. During the rolling process of the slab, the rolling cooling water encounters the red-hot, high-temperature steel slab and rapidly atomizes, entraining high-temperature oxidized powder and splashing around. The rollers bring bearing housings to cause greater impact on the window surface of the frame. The gap between the rolling mill stand and the sliding surface of the bearing seat exceeds the management limit. Because of the particularity of the rolling mill archway, only online repair can be realized. The traditional online repair method is to use soil equipment to d...
