Abstract

The invention provides a method, system and device for controlling automatic slag feeding of a continuous-casting crystallizer. The method, system and device are based on a slag feeding robot with six motion shafts. A novel automatic slag feeding control system structure is formed by taking the slag feeding robot as the core, cooperating with a quantified slag feeding device having stability and adaptability, combing air-pressure detection, temperature detection, slag-thickness detection, and material bin detection and other detection methods, and finally being supported by safety protection measures for area protection. Therefore, stability and uniformity of the slag feeding process are improved, and production quality of casting blanks is improved. In addition, the invention belongs to automatic closed-loop control, existing information of a casting machine and detection information of the slag feeding robot are combined, so that parameters and operation states can be corrected and adjusted in real time, the stability and uniformity of the slag feeding process in the production process can be guaranteed without manual interference.

Description

technical field [0001] The invention relates to the technical field of automatic control of metallurgical continuous casting, and more specifically relates to a method, system and device for automatic slag addition control of a continuous casting crystallizer. Background technique [0002] When a continuous casting machine casts a billet, adding mold slag to the surface of molten steel in the mold is the most important process in continuous casting production. Mold slag plays an extremely important role in continuous casting production, such as preventing secondary oxidation, lubricating and Adsorb impurities, etc. The continuous casting process requires mold slag to form a three-layer structure of molten layer, sintered layer and powder slag layer during the casting process in order to play a better role. [0003] At present, the main slag adding methods are divided into manual slag adding and mechanical slag adding, which mainly rely on manual settings to adjust the speed...
