Automatic balancing control system and method for plurality of hydraulic cylinders of continuous beam blank casting tundish

Abstract

The invention discloses an automatic balancing control system and method for a plurality of hydraulic cylinders of a continuous beam blank casting tundish, and belongs to the technical field of industrial automatic control. The system is used for lifting four independent hydraulic cylinders of the tundish on a tundish car. The automatic balancing control system comprises a controller, a plurality of position sensors and a plurality of servo valves, wherein one position sensor and one servo valve are mounted on each hydraulic cylinder; the servo valves can drive the hydraulic cylinders; the position sensors are connected to the controller and used for sending the data of detected actual positions of the hydraulic cylinders to the controller. The system can solve the problem that the tundish inclines after being lifted and put into use, and has the advantages of being simple in structure, and reasonable in theory. The system and the method can perform automatic balancing control for the tundish in the lifting process, and the design precision requirement can be met, so that the normal production can be ensured.

Description

technical field [0001] The invention belongs to the technical field of industrial automation control, and relates to the lifting position direction of a hydraulic cylinder, in particular to an automatic balance control system and method for a hydraulic cylinder in the continuous casting of special-shaped blanks. Background technique [0002] The 4# special-shaped billet continuous casting machine of the No. 3 Steel Rolling Plant of Masteel was built in 2005. The casting machine was contracted by SMS-Concast as a general contract. The upper and lower tundishes of the two tundish trucks are controlled by hydraulic pressure. There are four independent lifting control hydraulic cylinders on each tundish car. Due to the defect of the foreign control program, the synchronous function of the four hydraulic cylinders for tundish car lifting cannot be used, so that the tundish bag will tilt after a period of use. Even stuck, difficult maintenance, has seriously affected the productio...

There are four independent lifting control hydraulic cylinders on each tundish car. Due to the defect of the foreign control program, the synchronous function of the four hydraulic cylinders for tundish car lifting cannot be used, so that the tundish bag will tilt after a period of use. Even stuck, difficult maintenance, seriously affecting the production efficiency, also has a certain safety hazard
