Problems solved by technology

[0012] (1) Since the shaking furnace is operated by workers, the operating strength and angle are completely controlled manually. Therefore, the situation that the shaking furnace is too strong may cause slag overflow at the furnace mouth, or the shaking furnace is too slow to cause the slag layer to pass through the tap hole. Long, the amount of slag is large; and for the angle of the shaking furnace, due to the artificial control of the angle, ther

Embodiment Construction

[0073] In the following, the method and system for controlling the tapping flow rate of the converter fully automatic tapping described in the present invention will be further explained and illustrated in conjunction with the accompanying drawings and specific embodiments of the specification. However, such explanations and illustrations do not constitute inappropriate technical solutions of the present invention. limited.

[0074] figure 1 It is a schematic flow chart of the method for controlling the tapping flow rate of the converter fully automatic tapping described in the present invention in one embodiment.

[0075] Such as figure 1 As shown, in this embodiment, the tapping flow control method includes the following steps:

[0076] (1) Obtain the weight G of molten steel smelted in the converter by calculation 1 ;

[0077] (2) Set the initial angle θ of the converter at the beginning of tapping based on the weight of molten steel in the converter 0 ; and set the ta...

Abstract

The invention discloses a tapping flow control method for full-automatic converter tapping. The method comprises the following steps that (1) the weight G 1 of molten steel in a converter is obtainedthrough calculation; (2) the initial angle Theta 0 of the converter when tapping starts is set based on the weight of the molten steel in the converter, and target tapping flow Q<aim> (t) is set; (3)when the tapping starts, actual tapping flow Q<real> (t) is compared with the target tapping flow the Q<aim> (t) in real time, if the Q<real> (t) is larger than or equal to the Q<aim> (t), the inclination of the converter is reduced, and if the Q<real> (t) is smaller than the Q<aim> (t), the inclination angle of the converter is increased; and in the tapping process, the walking displacement amount xt of a ladle trolley is controlled at the same time, so that the ladle trolley is always located at an impact point of tapping steel flow; and (4) when the condition that the tapping is finished isdetected, the is stopped and the converter is lifted. In addition, the invention further discloses a tapping flow control system for full-automatic converter tapping.

Description

technical field [0001] The invention relates to a method and system for automatic steelmaking in a converter, in particular to a method and system for fully automatic steel tapping in a converter. Background technique [0002] At present, major steel mills around the world basically have automatic converter smelting, which can effectively improve the success rate of steelmaking, shorten the smelting cycle, improve output and quality, reduce raw material consumption and cost, and greatly reduce the labor intensity of workers. However, although the automatic steelmaking of the converter has been relatively popular in the prior art, the tapping of the converter is generally carried out manually. [0003] Usually converter tapping includes the following steps: [0004] 1) Determine that the composition and temperature of the molten steel end point meet the tapping requirements; [0005] 2) After driving the ladle car to the position of accepting molten steel; [0006] 3) The ...
