System and method for controlling continuous casting rotary table water gap

Abstract

The invention discloses a system and method for controlling a continuous casting rotary table water gap. The system comprises a main hydraulic module, an emergency hydraulic module and an execution module; the main hydraulic module and the emergency hydraulic module are connected in parallel and then connected with the execution module; the main hydraulic module inputs first driving pressure to the emergency hydraulic module, and the emergency hydraulic module inputs second driving pressure to the execution module; the execution module is used for opening or closing the continuous casting rotary table water gap; the emergency hydraulic module comprises an uninterruptible power supply, a hydraulic station and an operation switch box; a pipeline of the hydraulic station is in butt joint witha pipeline of the main hydraulic module, and the operation switch box is used for controlling the on-off of the hydraulic station; and the uninterruptible power supply uninterruptedly provides powerfor the hydraulic station. The system overcomes the problems that in the prior art, when special conditions, such as power failure of a continuous casting machine, oil leakage and pump trip of the hydraulic station, occur, the bale water gap cannot be effectively closed, and is out of control, and molten steel in a tundish is full and overflows so that serious consequences can be caused.

Description

technical field [0001] The invention relates to the technical field of continuous casting rotary table control, in particular to a continuous casting rotary table nozzle control system and method. Background technique [0002] At present, the ladle nozzles used on the continuous casting ladle turret all adopt the sliding plate method, and the opening and closing are realized by the action of the hydraulic cylinder. In the design of the system, the main hydraulic station of the continuous casting controls many hydraulic equipment such as ladle lifting, ladle cover lifting and rotating, ladle nozzle, tundish lifting and lateral movement, tension straightening machine, etc.; In special cases such as oil leakage in the hydraulic station and pump jumping, the pressure of the main hydraulic system will be unloaded in a short period of time. When the personnel on the post find the problem, because the system pressure has been unloaded, the large bag water outlet cannot be effective...

AI Technical Summary

Problems solved by technology

[0004] In view of the above technical problems, the purpose of the present invention is to overcome the problems in the prior art that the ladle nozzle cannot be effectively closed, the ladle nozzle is out of control, and the ladle nozzle is out of control when there are special circumstances such as continuous casting machine power failure, hydraulic station oil leakage and pump jumping. The overflow will cause serious consequences, thus providing a continuous casting rotary table nozzle control system and method that can ensure effective and reliable closure of the nozzle in the event of an emergency during use, thereby ensuring production safety
