How to choose good quality nodulating agent? Fengfan Silicon Industry Co., Ltd. to tell you what good spheroidizing agent?
1. Affinity of spheroidized elements with sulfur, oxygen and other elements in molten iron. It has a strong affinity, and forms compounds with it, as the foreign core in the solidification process of molten iron, such as rare earth, magnesium, calcium and other spheroidized elements;
2. The ability of spheroidizing elements to change the morphology of graphite from flaky to spherical;
3. The density and boiling point of the spheroidizer are lower than that of liquid iron. Low density can automatically float in molten iron, the boiling point is lower than the temperature of molten iron treatment, magnesium can be converted into a gaseous state at the temperature of treatment, there is a self-stirring effect, so as to improve the effect of spheroidization;
4. Spheridizer dense, no segregation, no shrinkage porosity, no powder;
5. The particle size distribution of spheroidizer is uniform, no powdery alloy, obtuse Angle multi-deformed particles is better.
The above is our company's description of the use of nodulating agent. If you need nodulating agent, please contact us.
