Problems solved by technology

[0003] At present, most steel mills adopt the method of manual control of converter tapping, and there are the following problems in manual control of tapping: the converter is tilted too fast, and the molten steel slag is easy to flow out of the large furnace mouth; ; The tilting angle of the converter is poorly matched with the position of the ladle trolley, resulting in molten steel not flowing into the ladle or insufficient stirring; the alloy rotating launder swing is incorrectly coordinated with the tilting angle of the converter and the moving

Abstract

The invention relates to metallurgical steelmaking technologies, and aims to provide a converter intelligent tapping device and a control method. The device comprises a converter steelmaking secondarycontrol system, a converter deslag detection system, a taphole slag blocking system, a converter opening monitoring module, a tapping monitoring module, a communication control module and a deep learning host, wherein the converter opening monitoring module is provided with a converter opening monitoring probe and a converter opening monitoring and processing unit; the tapping monitoring module is composed of a tapping monitoring probe and a tapping monitoring and processing unit; and the communication control module is connected with the deep learning host, the converter opening monitoring module, the tapping monitoring module, the converter steelmaking secondary control system, the converter deslag detection system and the taphole slag blocking system, so that two-way intercommunicationof data information and control signals is achieved. Intelligent prediction and control of converter tapping can be achieved, the tapping time is shortened, and the tapping efficiency is improved; the tapping process is reproducible, traceable and high in safety; and the molten steel quality is improved while the yield of molten steel is increased.

Description

technical field [0001] The invention belongs to the technical field of metallurgy and steelmaking, and in particular relates to a converter intelligent tapping device and a control method. Background technique [0002] During the converter steelmaking process, when the composition and temperature of the molten steel meet the requirements of the current steel grade, the steel is prepared for tapping. When tapping, the converter body is tilted to a predetermined angle, and molten steel is injected into the ladle through the tapping hole. During the tapping process, the tapping worker observes the steel flow, liquid level in the furnace, ladle clearance and other comprehensive conditions at the observation window behind the furnace, continuously increases the tilting angle of the converter, and adjusts the positions of the ladle trolley and slag tank car at the same time. Avoid the liquid steel surface in the converter being too close to the tap hole, causing the molten steel ...
