Roller wear self-healing device and control method thereof

Abstract

The invention relates to a roller wear self-healing device and a control method thereof. The roller wear self-healing device comprises a working roller, heat-conducting silicone grease, a TEC electronic temperature control chip, a water cooler, a temperature sensor wire, a direct-current power source wire and temperature sensors. The temperature sensors are arranged at the cold end and the hot end of the TEC electronic temperature control chip; the hot end of the TEC electronic temperature control chip is in contact with the working roller through heat-conducting silicone grease; the cold end of the TEC electronic temperature control chip is contacted and fixed with the water cooler through heat-conducting silicone grease; the water cooler is directly connected with a water pump and a circulating water tank; and the TEC electronic temperature control chip is connected with a direct-current power supply. The working roller is partitioned, and each section is independently adjusted and controlled; and the roll shape is monitored in real time according to an existing roll shape abrasion forecasting technology, the temperature of the TEC electronic temperature control chip is regulated and controlled online through a signal acquisition system, a temperature control system and the like, and then dynamic online compensation is conducted on the abraded roll shape. The method is high in plate shape regulation and control capacity, flexible, changeable and easy to control, and can be used for compensating the roller shape of the abraded roller so as to prolong the life cycle of roller replacement.

Description

technical field [0001] The invention relates to the technical field of roll shape curve regulation and control, in particular to a roll wear self-healing device and a control method thereof. Background technique [0002] The roll is the main executive element of the rolling process and undertakes the main task of metal plastic forming. During the metal rolling process, the roll can resist the deformation of the rolled piece with its own deformation, and then realize the forming of the rolled piece. However, in this process, the roll needs to bear the effects of rolling pressure, roll bending force, lateral friction force and non-uniform contact pressure between the rolls, which will further cause the material reduction of the roll itself, that is, wear and tear. When the wear reaches a certain level, the roll gap of the rolling mill is affected by the change of the roll shape and is difficult to control, which eventually leads to the problem of the shape and thickness of th...
