Abstract

The invention relates to a tundish nozzle quick-change hydraulic control system of a continuous casting machine, which comprises a plurality of drive oil cylinders, wherein piston rods of the drive oil cylinders are respectively connected with nozzle gates; push working cavities of all the drive oil cylinders are respectively communicated with an oil opening A of a double throttle check valve by hydraulic pipelines; return working cavities of all the drive oil cylinders are respectively communicated with an oil opening B of the double throttle check valve by hydraulic pipelines; oil supply openings P of all the double throttle check valves are respectively communicated with an oil opening A of a three-position four-way electromagnetic valve by hydraulic pipelines; and oil discharge openings T of all the double throttle check valves are respectively communicated with oil openings B of the three-position four-way electromagnetic valves by hydraulic pipelines. The invention aims to provide the tundish nozzle quick-change hydraulic control system of the continuous casting machine, which can greatly improve the running reliability of equipment, reduce or prevent serious damage of equipment and product scraping caused by that the nozzle gates can not move to the position accurately, lead the yield of the production line of the continuous casting machine to keep stable and enable the quality of products to have higher guarantee.

Description

technical field [0001] The invention relates to a hydraulic control system. Background technique [0002] The nozzle of the existing tundish of the continuous casting machine is usually opened or closed by an oil cylinder. In the actual production process, the hydraulic system of the nozzle gate of the tundish of the continuous casting machine will inevitably break down, resulting in failure during the production process. If the sliding gate cannot be moved in place accurately, once such a problem occurs, it may cause serious damage to the equipment and scrap the product, which will not only cause huge economic losses, but even endanger the safety of on-site personnel. Contents of the invention [0003] The purpose of the present invention is to provide a device that can greatly improve the reliability of equipment operation, reduce or avoid serious equipment damage and product scrapping caused by the inability of the gate gate to move accurately, so that the output of the...
