Name Slag Remover Place of Origin Xinyang, Henan, China Expanded or not Unexpanded HS Code 3824999990 Brand Name Daye Model R-2, R-3, R-4, R-5 Appearance Short grained, light yellow or grey white Grain Size(mm) 2.36-0.85 (8-18 mesh) Chemical SiO2 72.30% Composition A12O3 12.35% MgO 0.60% Fe2O3 1.10% Expansion Coefficient â?¥16 Expansion Temperature(°C) 880-1050 Mohs scale of hardness(g/ml) 5.5 Loss of Ignition 4.1 Bulk density(g/ml) 0.95-1.15 PH 7 Moisture â?¤0.5% Application Steel & Iron casting, stainless steel casting, grey iron, ductile iron, molten metal purification Our advantages: 1. High purity - Control the consistency of raw material from the mine resource. - Introduce automatic whole-process equipment to ensure product consistency. - Not allowed any harmful impurities during raw material & production process. 2.Fine classification - Choose different raw materials according to their characteristics. - Various product category, to provide customized slag treatment scheme 3. Environment friendly & health - The reaction process is only a change of physical state, not chemical reaction, so no solution to the molten metal. - The physical reaction is stable and non-toxic and tasteless. It does not produce soot & not affect human health. 4).Mechanism of slag removing - Low softening point, high viscosity. After being scattered into the metal surface, the product will expand and - Spread out to cover the entire surface, melt rapidly, form a high-viscosity "film" finally, which sticks to the scum in the metal, to make slag collected and removed.
