Advantages: 1. High-density, high-strength, anti-erosion ability; 2. High melting loss resistance, strong permeability of molten steel resistance; 3. High-volume and stability of the resistance; 4. Good sintering performance, to form a whole solid layer sintered at a high temperature, long service life; 5. Easing to construct and repair Technics: It is made of high-purity raw material that originated from a synthetic process of granulating under high temperature calcinations. By way of rapid sintering between magnetite particles and basic fine powder, an integrated solid sintering layer has been formed. With easy method of application, it has good hot repairing properties. Its service life has reached or surpassed that of imported materials.
