Deslagging agent (covering agent) is made by certain particle size perlite ore after special processing, to sprinkle in the fresh-baked steel (iron) water surface. Then the perlite volume is rapidly expanded of 4-30 times with slag-off, insulation work, etc. So we call it cleaner agent. It replaces straw ash or asbestos plaster as molten iron cover, cleaner insulation material in the foundry industry and opened new areas of perlite application. Product advantage: Insulation performance is good, in general, can reduce 20% -30% of molten iron cooling rate. Good residue collection performance, easy slag-off, good for hot metal purification. Better to globule stable, weaken magnesium light£¬improve the globule effect. Reduce environmental pollution, improve working conditions. Good economic results, can reduce 30% cost. Easy to use, it is better for promotion of products. Weight
