5-8 Rare Earth Silicon Magnesium Spheroidizing Agent

Spheroidizing agent, also known as rare earth magnesium ferrosilicon alloy, is mainly used for ductile iron. After adding molten iron, it can be used for spheroidization, desulfurization and degassing, and can improve the purity of casting water. It can also react with low melting point impurities such as arsenic, zinc, lead, etc. to generate compounds with lower melting points that do not melt in iron, eliminating these impurities and preventing interference elements from damaging spheroidization. Characteristics of spheroidizing agent: Strong spheroidizing ability, smooth reaction, high absorption rate, no worries of degradation 1. Stable composition with minimal fluctuations; 2. High alloy purity and low magnesium oxide content; 3. The alloy structure is dense, and it is not easy to float during the spheroidization process; 4. The composition and particle size can be appropriately controlled according to requirements. How to choose the right spheroidizing agent The correct…
