Abstract

Proposed in the present invention are a refinement apparatus and a refinement method, the refinement apparatus comprising: a container unit having an open upper portion and a space for refining melt formed therein; a nozzle unit which is formed so as to blow gas and is installed in the container unit; a camera unit, provided above the container unit, for photographing a molten metal surface of the melt; and a control unit for calculating the size of naked molten metal on the molten metal surface by using the molten metal surface image obtained from the camera unit, installation information of the camera unit, and performance information of the camera unit, in which a gas flow rate may be controlled so that the size of the naked molten metal that is formed in the molten metal surface during an LF refining process falls within a preset reference size.

Description

technical field [0001] The present disclosure relates to refining equipment and refining methods, and more particularly, to refining equipment and refining methods capable of accurately calculating the size of exposed molten metal during an LF refining process and appropriately adjusting gas flow based on the calculated size. Background technique [0002] The molten steel produced by the converter refining process is transferred to the ladle furnace (LF) refining process for composition adjustment, temperature control and inclusion removal. After that, the composition of the molten steel is adjusted by inputting ferroalloy or carbon material into the molten steel, and the temperature is adjusted by performing strong bubbling or generating an electric arc in the LF refining process. These steps are performed at the initial and intermediate times of the process. [0003] At the end of the LF refining process, the molten steel is subjected to weak bubbling (or "clean bubbling"...
