Abstract

The invention discloses automatic plate blank continuous casting machine tundish pouring method and an automatic pouring system. The pouring method comprises the following steps of: a) opening a water gap of a tundish, and pouring molten steel in the tundish into a crystallizer; b) after the water gap of the tundish is opened for certain time, leading a vortex flow transducer to automatically move to a work station from a waiting station so as to detect height of the molten steel level in the crystallizer by utilizing an automatic escape device; and c) when the vortex flow transducer detects that the molten steel level in the crystallizer reaches a set height, starting a withdrawl and straightening machine and promoting the casting speed to a target set value according to the process requirement. The automatic plate blank continuous casting machine tundish pouring method and the automatic pouring system can solve the problem that the plate blank continuous casting machine of the existing vortex flow molten steel level detector can not realize automatic pouring, reduce the risk on pouring breakout, improve the pouring success rate, and saving the cost.

Description

technical field [0001] The invention relates to the field of steelmaking and continuous casting, in particular to an automatic pouring method and an automatic pouring system for a tundish of a slab continuous casting machine. Background technique [0002] When the tundish of the continuous casting machine is poured, the nozzle of the tundish is opened, and the molten steel in the tundish is injected into the crystallizer equipped with dummy ingots through the nozzle. splash. As the molten steel fills the gap between the dummy ingot and the mold and reaches a certain height in the mold, the splash of molten steel decreases, and the tension leveler starts to slowly pull the dummy ingot and the billet solidified with the dummy head out, and then slowly increase the pulling speed until the set target pulling speed. [0003] The above-mentioned pouring process is completed by the operator controlling the opening of the tundish nozzle and the casting speed, which is called manua...
