Hello everyone, I am the youngest girl in the factory.

It's time for the popular science class again today!

Today we will talk about some measures to prevent spheroidization and recession:
1. The time from incubation to pouring must be short, the longer the time, the more serious the incubation decline;
2. The molten iron should maintain a proper amount of spheroidizing element content
3. Reduce the sulfur content of the original molten iron and prevent the molten iron from oxidizing
4. After the molten iron is spheroidized and slag removed, the surface of the molten iron needs to be covered with a covering agent to isolate the air to reduce the escape of Mg and Re elements.

Follow me, the youngest girl in the factory.
