Crystallizer liquid level stopper rod servo hydraulic control system

Abstract

The invention aims to provide a crystallizer liquid level stopper rod servo hydraulic control system. One end of a stopper rod mechanism is in rigid connection with a servo cylinder, the other end ofthe stopper rod mechanism is provided with a stopper rod, a displacement sensor is mounted on the servo cylinder, the servo cylinder is connected with a servo control device, the servo control deviceis connected with a pressure regulating device and a computer, the pressure regulating device is connected to a servo power station, the stopper rod extends into a water gap of a tundish and can closeor open the water gap to adjust flow of molten steel, the water gap is connected to a crystallizer, and the crystallizer is provided with a liquid level detecting device. The crystallizer liquid level stopper rod servo hydraulic control system has the beneficial effects that the servo cylinder is adopted for controlling, and therefore high specific precision, fast response and wide adaptability are achieved through the servo cylinder peculiarly.

Description

technical field [0001] The invention belongs to the technical field of metallurgy and relates to a novel crystallizer liquid level stopper rod servo hydraulic control system. Background technique [0002] At present, in the metallurgical industry, the crystallizer liquid level control of general plate, square and round billet continuous casting machines is to control the up and down movement of the stopper rod and then control the amount of molten steel flowing out through the tundish nozzle to ensure that the fluctuation of the molten steel liquid level in the mold is within a certain range. , the control process has gone from manual to automatic. The standard configuration of the stopper mechanism of the continuous casting machine has always been the electric cylinder control. However, with the development of the market, the customer's demand for high-speed casting machines has increased, and the electric cylinder control can no longer be well satisfied. In terms of applic...

The standard configuration of the stopper mechanism of the continuous casting machine has always been the electric cylinder control. However, with the development of the market, the customer's demand for high-speed casting machines has increased, and the electric cylinder control can no longer be well satisfied. Use requirements, servo cylinder control is more recognized for its unique advantages of high precision, fast response, and wide adaptability (servo cylinders that can be achieved by electric cylinders can also achieve it), and can better meet market demand.
