High Strength Heating Insulation Covering Agent¹

Product Description Product features: Riser covering agent is a special functional material used in the casting process to cover the riser of molten steel/iron. It forms an insulation layer to delay the solidification of the metal liquid, improve the shrinkage effect, reduce defects such as shrinkage and porosity, and significantly improve the yield and mechanical properties of castings.1. Super insulation: low thermal conductivity (≤ 0.1W/m · K), delaying riser solidification time by 30% -50%2. Efficient slag collection: adsorb surface impurities of molten steel, purify molten metal3. Low burn rate: Good chemical stability, reducing metal oxidation loss4. Environmentally friendly and harmless: no toxic substances volatilize, safe to use5. Adaptive coverage: automatically spreads and forms a uniform insulation layer when encountering molten steelReduce heat lossReduce the heat loss of the riser, decrease the temperature of the molten metal, and increase the density of the castingImprove shrinkage efficiencyUsing a covering agent without using a riser sleeve can form a relatively complete plane or U-shaped depression on the surface of the riser, with no shrinkage holes on the casting, improving the efficiency of filling shrinkageReduce impurities in molten steelCan reduce impurities in steel water and clean steel
