A kind of roll wear self-healing device and control method thereof

Abstract

The invention relates to a roll wear self-healing device and a control method thereof. The device comprises a work roll, a thermal conductive silicone grease, a TEC electronic temperature control sheet, a water cooler, a temperature sensor wire, a DC power supply wire and a temperature sensor; the temperature sensor Set at the cold end and the hot end of the TEC electronic temperature control sheet; the hot end of the TEC electronic temperature control sheet and the work roll are in contact with the thermal grease; the cold end of the TEC electronic temperature control sheet is fixed by contact with the water cooler through the thermal grease; water cooling The water pump and circulating water tank are directly connected to the device; the TEC electronic temperature control chip is connected to the DC power supply. The work rolls are divided into different sections, and each section is independently adjusted and controlled; according to the existing roll shape wear prediction technology, the roll shape is monitored in real time, and the temperature of the TEC electronic temperature control sheet is regulated online through the signal acquisition system, temperature control system, etc. , and then perform dynamic online compensation for the wear roller shape. The invention has strong plate shape regulation capability, is flexible and easy to control, and can be used for compensating the worn roll shape of the roll to prolong the life cycle of the roll change.

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 it undertakes the main task of metal plastic forming. In the process of metal rolling, the roll can resist the deformation of the rolling piece by its own deformation, and then realize the forming of the rolling piece. However, in this process, the rolls need to withstand the effects of rolling pressure, bending force, lateral friction and non-uniform contact pressure between the rolls, which further reduces the material of the roll itself, that is, wears. When the wear reaches a certain level, the roll gap of the rolling mill is difficult to control due to the influence of the roll shape change, and finally induces the problem of flatness and thickness. In order to ensure the stable produc...
