This invention discloses a method for controlling inclusions in titanium-containing ultra-low carbon steel. The steelmaking process is as follows: converter process – LF process – RH process – slab continuous casting process. After aluminum deoxidation and alloying in the RH process, low-reactive slag is added. As the vacuum molten steel circulates, this slag floats to the surface and remains at the steel-slag interface, hindering oxygen transfer from the ladle slag to the molten steel. Simultaneously, this substance has the ability to adsorb inclusions in the steel. By controlling the process parameters of the RH process, oxygen transfer from the ladle slag to the molten steel is effectively prevented, avoiding secondary oxidation of titanium and aluminum elements in the deoxidized steel and controlling the inclusion content in the steel. This invention's control method effectively prevents oxygen transfer from the ladle slag to the molten steel and avoids secondary oxidation of easily oxidized elements such as titanium and aluminum in the deoxidized steel, resulting in significant economic and social benefits.

This invention discloses a copper slag modification and granulation system with real-time adjustable atmosphere and composition, comprising: a smelting furnace with an adjustable fume hood on top; an insulated chute for conveying the modified slag to the granulation section; a granulation device for dry centrifugal granulation of the modified slag; the adjustable fume hood having: an oxidizing gas interface for introducing oxidizing gas into the furnace; a reducing gas interface for introducing reducing gas into the furnace; a backup gas interface for introducing either oxidizing or reducing gas; an openable / closable observation / feeding port for observing the furnace state and / or adding modified materials to the furnace; and a flue gas outlet for discharging the flue gas generated in the furnace. This system integrates multiple gas interfaces and a feeding port on the adjustable fume hood of the smelting furnace, enabling active control of the slag's oxidation-reduction state and chemical composition during the slag holding stage, thereby optimizing the slag's properties and creating conditions for subsequent granulation processes.
