Monitoring device for tapping of converter/electric furnace and control method

Abstract

The invention relates to the technical field of metallurgical steelmaking, and aims to provide a monitoring device of the tapping of a converter / an electric furnace, and a control method. The monitoring device of the tapping of the converter / electric furnace comprises an infrared detector A, an infrared detector B, a camera, a central server and a monitoring terminal, wherein the infrared detector A is mounted on the tapping side of the furnace; the infrared detector B is mounted on the deslagging side of the furnace; the camera is mounted above a bale tapping position; and the infrared detector A, the infrared detector B and the camera are respectively connected with the central server. The monitoring device disclosed by the invention can comprehensively monitor the tapping of the converter / electric furnace, to be specific, monitor whether a slag ladle is in the position, monitor whether the bale is in the position, monitor the deslagging destination before tapping, monitor whether steel slag is discharged after tapping, monitor whether the bale is emptied , and the like, the potential safety hazard of the tapping caused by the fact that the slag ladle and the bale are not in the position can be avoided, the tapping efficiency is improved, the quantity of the steel slag flowing into the bale is reduced, and the molten steel quality is improved.

Description

technical field [0001] The invention relates to the technical field of metallurgy and steelmaking, in particular to a converter / electric furnace tapping monitoring device and a control method. Background technique [0002] In the field of metallurgical steelmaking, after the converter / electric furnace completes the molten steel smelting through complex oxidation-reduction reactions, the molten steel is transferred to the ladle for use in the next process. This process is called tapping. In order to reduce the flow of steel slag into the ladle, monitor the quality of molten steel, and save post-processing costs, the following two methods are usually adopted: 1) Perform slag dumping operation before tapping to reduce the total content of steel slag in the converter / electric furnace; 2) Control the output The amount of steel slag flowing into the ladle during the steel process. [0003] The steel slag flowing into the ladle during the tapping process is usually divided into th...

Problems solved by technology

[0006] Although the infrared detection method has achieved good application results in the detection technology of BOF / EAF tapping slag, it still cannot meet the requirements of modern steelmaking for steelmaking efficiency and production safety. For example, the current infrared detection method only detects In the process of steel flow, the slag situation cannot detect the change of the slag dumping process and the headroom height of the ladle. In addition, the monitoring of the ladle in place is helpful for timely tapping, reducing the residence time of molten steel, and improving the turnover efficiency of the ladle. great significance
