Rare Earth Composite Refining Agent

The reaction time in the furnace space is limited, and residual hydrogen, oxygen, and sulfur can easily cause porosity, slag inclusion, and shrinkage porosity. Steel is prone to cold and hot brittleness. Cast iron & steel grain refining agents can deoxidize, dehydrogenate, and remove sulfur, purify molten steel, improve the density of steel, enhance the mechanical properties of steel, and increase impact toughness by 20% -30%.   Molten iron may have coarse graphite, multiple flakes, and uneven spheroidization, which can lead to poor strength of castings. Our molten iron performance improvement agents  can refine the structure, increase the amount and spheroidization rate of graphite, and improve the fluidity of molten iron. Effectively improve the quality of steel.   Ordinary steel is not corrosion-resistant and its performance decreases in high or low temperature environments. Our steel purification treatment agents has corrosion resistance, wear resistance, high temperature resis…
