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

Some netizens left a message asking how to improve the strength of cast iron smelted in an intermediate frequency furnace.

It is often said that the composition determines the organization, and the organization determines the performance.

This sentence is basically correct, but it is not comprehensive.

In addition to the composition factor, the cast iron smelting should focus on the following four aspects:

1. The chemical composition of the molten iron should be accurate and stable.

2. Eliminate non-metallic impurities and gases in molten iron.

3. Control the generation of harmful trace elements.

4. Accurately control the graphite core in the furnace.

follow me! I am the youngest girl in the factory.
