Full-automatic casting method for continuous casting machine

Abstract

The invention discloses a full-automatic casting method for a continuous casting machine. According to the method, firstly system secondary cooling water is started, a system makes a medium ladle sliding plate fully opened through a liquid control valve so that molten steel can rapidly flow into a crystallizer from the medium ladle, when the molten steel reaches a crescent face, a withdrawal and strengthening machine is automatically started, and meanwhile different withdrawal and strengthening machine raising speeds are selected according to different steel grades, different casting blank fracture surfaces and different molten steel temperatures; and when the molten steel flows out of the crystallizer and after the molten steel forms a blank shell on the surface of the crystallizer, the casting blank position is calculated according to the casting machine pulling speed, a driving roller position tracking system is used for performing lifting control on a driving roller, and the system guarantees the quality in the casting blank casting process through soft clamping, dynamic light pressure and the like. According to the method, by means of match and linkage of continuous casting complete process parameters, full-automatic casting for continuous casting is achieved, and the problems that the manual casting fault rate is high, and the casting blank quality is not stable are solved; and in the control system, the molten steel liquid face can be stably controlled through real-time contrast adjustment of the casting machine pulling speed and the opening degree of the sliding plate

Description

technical field [0001] The invention relates to a pouring method for a continuous casting machine, in particular to a fully automatic casting method for a continuous casting machine. Background technique [0002] At present, there is no automatic pouring method for continuous casting machines at home and abroad, and manual casting is all used. In the process of manual pouring, it is difficult to grasp the matching between the casting speed of the continuous casting machine and the opening of the slide plate. If the casting speed is too fast and the steel flow does not keep up, it will cause steel leakage and interruption of the casting machine; if the casting speed is lower than the steel flow, Will cause the molten steel of the crystallizer to overflow, cause the shutdown of the casting machine, and there is a potential safety hazard of molten steel splashing. In addition, if the casting speed does not rise steadily, it will easily lead to fluctuations in the liquid level,...
