What is the role of spheroidizing agents in steel
1. Refining grain size: In the process of steel production, liquid steel will gradually solidify through cooling, and grain size will form. The use of spheroidizing agents can improve the morphology and distribution of grains, refine them, and enhance the physical properties of castings;
2. Improving the casting performance of steel: In addition to refining grain size, spheroidizing agents can also act on the liquid state of steel, thereby reducing its liquid composition and improving its flowability and castability. This can make the surface of the casting smoother and more uniform, with no defects such as pores inside;
3. Improving the mechanical properties of steel: The use of spheroidizing agents can increase the hardness, strength, and toughness of steel, making it more wear-resistant and durable during use, thereby meeting higher usage requirements.
