| description | PURPOSE:To produce a covering material having excellent corrosion resistance and spalling resistance for desiliconizing runner in blast furnace casting floor by adding the specific ratio of small grain and fine powder of Al2O3 quality raw material and super fine powder of refractory to MgO quality raw material as main composition. CONSTITUTION:The covering material is composed of adding 10-30wt% total of Al2O3 quality raw material, which combines almost the same quantities for the small grain and the fine powder, 2-8wt% super fine powder of refractory, to the natural and/or artificial MgO quality raw materials as the main component. Further, as the MgO quality raw material, the natural magnesite clinker, electromelting magnesia, etc., containing about >=85wt% MgO is used, and Al2O3 quality raw material containing about 85wt% and as the super fine powder of refractory, SiO2, Al2O3, etc., having |
