Method, device and equipment for controlling tapping of converter
During the steel discharge process of the converter, pulsed gas spraying is performed according to the detection liquid level control bottom blowing device, which solves the problem of excessive iron content of the slag, and effectively separates the slag and iron beads in the molten steel, which improves the yield rate and saves energy consumption.

Abstract
The invention discloses a tapping control method, device and equipment of a converter, and the method comprises the following steps: in the tapping process of the converter, the detection liquid level of molten steel of the converter is obtained, and the capacity of the converter is 100t-300t; if the detected liquid level is larger than the preset liquid level, a bottom blowing device is controlled to conduct pulse type gas injection into the converter, so that slag and iron beads of the molten steel are separated; and if the detected liquid level is smaller than or equal to the preset liquid level, the bottom blowing device is controlled to stop pulse type gas injection into the converter. The technical problem that the iron content of the slag is too high is solved.
