Abstract

The invention discloses a monitoring device for an LF furnace. A furnace cover is arranged above a steel ladle of the LF furnace. A monitoring port is formed in the furnace cover. A camera assembly isfixed on the monitoring port. A lens of the camera assembly is downward or obliquely downward to monitor molten steel in the steel ladle. According to the monitoring device, the exposure situation ofthe molten steel level in the furnace and the situation of refining slag are monitored in real time, the LF refining technology is optimized, precise control over a bottom blowing mode and the refining slag in the LF refining process is achieved, the LF refining efficiency and effect are improved, and the quality of the molten steel is improved.

Description

technical field [0001] The invention relates to the technical field of steelmaking, in particular to a high-temperature-resistant splash-proof and interference-proof video monitoring device for an LF furnace. Background technique [0002] LF furnace is one of the most commonly used refining methods in steelmaking process. The main function of LF refining is to adjust the temperature and composition of molten steel on the one hand, and to realize deoxidation, desulfurization and removal of inclusions on the other hand. The ladle bottom blowing condition and refining slag condition in the LF refining process are directly related to the LF refining effect and molten steel quality. [0003] According to the function of LF refining, the bottom blowing system in the LF refining process can be divided into four bottom blowing modes: strong stirring mode, medium stirring mode, weak stirring mode and slight stirring mode. Different bottom blowing modes are used in different refining...
