More Information
Summary:The invention provides a preparation method of a non-reactive drainage agent, which belongs to the technical field of metallurgical refractory materials. The preparation method comprises the followingsteps of (1) uniformly mixing two or more than two kinds of powder of potassium feldspar, albite, perlite, periclase, corundum and spinel in proportion to serve as a coating main body material, adding an inorganic binder, a carbonaceous material, a dispersing agent and water, and mixing to prepare a coating material, and 2) selecting one or more than two of periclase, corundum and spinel as aggregate, spraying a coating material accounting for 3-20wt% of the weight of the aggregate on the surface of the aggregate, and drying to obtain the non-reactive drainage agent.The drainage agent of thekind does not contain chromium ore and other chromium containing materials, the problems of chromium increase of molten steel and environmental pollution caused by use of chromium-containing materialscan be avoided, the proble
