Roll gap control method and device

Abstract

The invention discloses a roll gap control method and device which are applied to roll gap control of a continuous casting machine, and the method comprises the steps that a measured roll gap value and an online roll gap value of a roll pair of the continuous casting machine are obtained, the measured roll gap value is obtained through measurement of a sensor of the continuous casting machine, and the online roll gap value is obtained through measurement of measurement equipment except the sensor of the continuous casting machine; a comprehensive roll gap value is obtained according to the measured roll gap value and the online roll gap value; a first roll gap difference value is obtained according to the comprehensive roll gap value and a target roll gap value required by a process; and according to the first roll gap difference value, the roll gap of the double rolls of the continuous casting machine is adjusted. According to the control method, the roll gap of the double rolls of the continuous casting machine is accurately adjusted, the control accuracy and stability can be improved, the defects of center segregation, looseness, corner cracks and the like of the plate blank are reduced, and then the rolling quality of the plate blank is improved.

Description

technical field [0001] The invention relates to the technical field of continuous casting machine control, in particular to a roll gap control method and device. Background technique [0002] With the continuous upgrading of the manufacturing industry, the inspection, calibration, and maintenance of high-end equipment have become major issues that have to be resolved in the industry. An excellent and high-level casting machine roll gap measurement device can not only improve the detection accuracy of the continuous casting machine roll position, but also indirectly represent the level of manufacturing measurement equipment. Therefore, current research institutions, enterprises and institutions all use casting The research and application of machine roll gap measurement device is taken as a major scientific research topic. In the current steel market, state-owned steel enterprises should take advantage of their own advantages in talents, resources, and equipment to impact hi...

Problems solved by technology

Due to the influence of the production environment, the stability of the roll gap data measured and fed back by the sensor during this control process is poor, resulting in unreasonable roll gap control and affecting the rolling quality of the slab
