Effect of Refractories on Impurity of Molten Steel

Improve the quality of steel is an important indicator of lower inclusions in steel to improve the cleanliness of steel. With the improvement of cleanliness requirements of molten steel, people pay more attention to high temperature steelmaking refractory steel impurities in the impact. Steel in the various non-metallic inclusions mainly from refractory material, in the whole steelmaking alumina brick process, molten steel and refractory material firebrick refractory always keep in contact, therefore, between the two phases not only produce surface reaction can also produce erosion. Some of the inclusions in the steel in any state (in the grain boundary segregation, inclusions or precipitates, and invasive solid solution, etc.), although the trace, the organization of steel and material also has a great impact.
