Rare earth magnesium silicon 5-8ReMgFeSi spheroidizing agent

Introduction to spheroidizing agent: Spheroidizing agent, also known as rare earth magnesium ferrosilicon alloy, is an additive that can promote the crystallization of graphite into spherical shapes in ball milled cast iron. It is generally used in the field of cast iron casting. In the process of casting iron, the additive added to the molten iron to precipitate graphite into spherical shapes is called spheroidizing agent, and the spheroidizing agent containing rare earth elements is called rare earth spheroidizing agent. Spheroidizing agent model: 3-8 spheroidizing agent 5-8 spheroidizing agent 7-8 spheroidizing agent   The elements in the spheroidizing agent that affect the spheroidization effect Almost all cast iron factories now produce ductile iron, and different spheroidizing agents should be selected for different production conditions. Spheroidizing elements refer to the elements that can promote the spheroidization of graphite, causing the formation or increase of gra…
