Micro-scale cold rolling roll system space precision control method

Abstract

The invention discloses a micro-scale cold rolling roll system space precision control method. The method includes the following steps: through the analysis of working conditions, a detection method and a tool are selected, a roller system with completely exposed roller surfaces is processed according to a step A, a roller system with completely blocked roller surfaces is processed according to astep B, and a roller system with partially exposed roller surfaces is processed according to a step C; according to levelness and verticality unit offsets and the reference distance, between the roller drive side and the roller operating side, of a bearing seat, adjustment amounts are calculated, and the position of the bearing seat is finely adjusted; and the roller is re-measured after fine adjustment, the roller system with the completely exposed roller surfaces is processed according to the step A repeatedly, the roller system with the completely blocked roller surfaces is processed according to the step B repeatedly, and the roller system with the partially exposed roller surfaces is processed according to the step C repeatedly until final detection results show that the space precisions of the measured roller systems conform to assembly requirements. The micro-scale cold rolling roll system space precision control method achieves the technical effects of rapidly and effectively detecting the space precisions of the roller systems, meeting requirements of online assembly precisions, and effectively alleviating the problems of striped steel deviation, winding machine tower shape forming and striped steel plate shape forming.

Description

technical field [0001] The invention relates to the field of on-line assembly precision control of metallurgical equipment, in particular to a method for controlling the space precision of a micron-level cold rolling roll system. Background technique [0002] There are many roll systems in the cold rolling production line, including thousands of rolls such as steering rolls, tensiometer rolls, looper rolls, furnace rolls, coilers, and uncoiler mandrels. With the rapid development of metallurgical manufacturing technology in my country, the requirements for on-line assembly accuracy of cold-rolled roll systems have reached a new height, and the on-line assembly accuracy requirements of some roll systems have even reached 50μm / m, the traditional detection methods cannot meet the efficiency and accuracy at all. [0003] However, in the process of implementing the technical solutions in the embodiments of the present invention, the inventors of the present application found that ...

Problems solved by technology

[0005] The embodiment of the present invention provides a method for controlling the space precision of a micron-level cold-rolled roll system, which solves the problem that in the prior art, due to the fact that some roll systems do not have good detection conditions within a limited maintenance time, they cannot be quickly and effectively detected, and cannot meet the requirements. On-line assembly accuracy requirements, which in turn lead to strip deviation, coiler tower shape and strip shape problems caused by poor spatial accuracy of the roll system
