The requirements of EAF refractories


It can be seen that the refractory materials selected for each part of the steel-making electric furnace have the following requirements for performance:
1.Good chemical stability and volume stability;
2.The material composition is not easy to react with molten steel and SiO2, and it is not easy to produce nodules;
3.Not easy penetrated by molten steel;
4.It has good resistance to rapid cold and heat, and is not easy to break and peel; 5.High density, low porosity, uniform pore distribution, molten steel is not easy to penetrate;
6.High strength, can resist mechanical external impact and erosion.
