In order to solve the problems such as the low reliability of running

inaccurate monitoring of position and poor safety

the hydraulic beam piercing control device of a factory gate room is reformed.The modified piercing control device adopts a magnetostrictive displacement sensor and is equipped with a piercing position monitoring device to accurately display the piercing position on the control screen.At the same time

the 24 V DC double-valve redundant control electromagnetic valve is used instead of the 220 V AC single valve control electromagnetic valve.The actual situation shows that the improvement of the hydraulic beam piercing pin control device improves the reliability

control accuracy and safety of the equipment.
