Description

Spheroidizing agent smelting equipment Technical Field The utility model relates to the technical field of nodulizer smelting, in particular to nodulizer smelting equipment. Background The nodulizer smelting is a key link in the casting process and is mainly used for producing spheroidal graphite cast iron. The nodulizer is generally composed of magnesium, rare earth elements and the like, and graphite is promoted to be precipitated in a spherical shape by adding the nodulizer into molten iron, so that the mechanical property of cast iron is remarkably improved. The smelting process of the nodulizer requires strict control of temperature, reaction time and stirring conditions to ensure that the nodulizer is uniformly dispersed and fully reacts with the molten iron. The traditional spheroidizing agent smelting process mostly adopts an induction furnace or a resistance furnace, but the smelting process is easily influenced by external factors due to the high reactivity of the spheroidizing agent, so that the spheroidizing effect is unstable. The existing nodulizer smelting equipment generally has the problems of insufficient stirring and uneven reaction. Conventional equipment lacks efficient stirring mechanism, causes the nodulizer to be unevenly distributed in molten iron, and influences the nodulizing effect. Chinese patent CN222000632U proposes a smelting device for coating a nodulizer, which is additionally provided with a stirring structure to improve the mixing effect, but has the obvious defects that firstly, the stirring device is easy to wear in a high-temperature melt environment and has shorter service life, secondly, the stirring device is only arranged at the bottom, the stirring effect is limited, the nodulizer cannot be fully and uniformly distributed, and in addition, the device is not optimized for the sedimentation and segregation problems of the nodulizer, so that the reaction efficiency is reduced, and the nodulizing quality is difficult to ensure.
