Furnace bottom refractories directly withstand high temperature heat load and slag erosion, the working conditions of the molten pool is extremely harsh, the quality and life of the furnace bottom refractories on the safe operation of the furnace and smelting effect is very important. Foreign companies such as Ao magnesium company now widely used MgO-CaO-Fe2O3 dry pounding material for the bottom of the furnace, they are high calcium and iron magnesite as raw materials, high temperature (2250 ℃) firing and crushing process and become, this material is resistant to high temperatures, resistance to erosion, erosion, resistance to scouring, has a rapid sintering, high toughness, not easy to float the advantages of the use of very good results. At present, we mainly use synthetic high iron and high calcium sand as raw material, no matter the performance and quality can not be compared with Ao magnesium company. Our company adopts wet high iron and high calcium magnesium sand synthesized by a domestic company as the main raw material, supplemented by self-developed high iron and high calcium magnesium sand, the dry pounding material produced by scientific proportioning, the main performance and Magnesium Au is close to the company, petrographic analysis shows that the organization is uniform, the distribution of the CF cement phase is uniform, at the grain boundaries, which significantly improves the product's resistance to erosion and hydration, by a factory in the country, the life of the 50tUHP experiment, the life of the company has reached the physical level of Magnesium Au. Ao magnesium company physical level.
