Foundry Perlite Ore Slag Coagulant for Cast Iron (Model R3)
High Purity: The active ingredient reaches more than 96% with very few impurities.
Low Dust Content: The strict production process controls the particle size range of the product, achieves uniform product particle size, avoids dust during use, and maintains a clean production environment.
Low Water Content: After proper temperature processing, the product has a low water content, which prevents splash caused by crystal water flowing down from high, and makes the reaction more rapidly.
Low Softening Point: After the product is sprinkled on the surface of the molten metal, the part of the product in contact with the molten metal fuses rapidly to form a “skin film” with a “higher viscosity” that can glue or wrap the scum, achieving a fast dregs removing effect.
Cast Iron: The molten iron scum has a low viscosity and is in the form of loose sand. This product absorbs and sticks loose scum by forming a viscous puff, and the loose scum gradually forms a large piece of or a spherical shape in this way, which can be quickly removed finally.
Cast Steel: The molten steel itself has a large viscosity, but is relatively thin. The fluidity of the scum layer is stronger than that of the molten iron slag. The formation of viscous puffs at high temperatures can effectively increase the thickness of molten steel scum, reduce the fluidity of molten steel scum, and accumulate into large pieces, which facilitate the removal of the scum while preventing the scum from entering the cavity with the pouring.
Spread an appropriate amount of this product after feeding and before the molten metal is discharged (the amount of addition depends on the actual amount of scum and the viscosity of the molten metal). After the molten metal is poured into the ladle, another layer of this product can be evenly added to cover the molten metal to prevent heat radiation, reduce heat loss, and block the scum and prevent the scum inside the molten metal from entering into the cavity. When the scum is moved away, the product will expand rapidly due to contact with the liquid metal and form an insulation layer, making the temperature of the upper layer of scum remover lower, and the reaction is not sufficient, so please use a right tool to slightly mix the scum, so that the product will sufficiently contact with the scum layer and reach the best scum gathering effect.
