2. Manganese-silicon alloy can not only deoxidize, but also increase the manganese content in steel and improve the strength of steel, so the proportion of manganese-silicon alloy used as deoxidizer is gradually higher than that of ferrosilicon.

3. The connection between ferrosilicon and manganese silicon lies in the same function.

4. Ferroalloy is an alloy formed by iron and other elements, which can be divided into silicon, manganese, chromium and other alloys according to the elements contained.

5. Manganese silicon and ferrosilicon are mainly used for two purposes, one is as deoxidizer, and the other is as alloying agent to eliminate excessive oxygen and sulfur in molten steel and improve the quality and performance of steel.

6. Ferroalloy: In a broad sense, ferroalloy refers to a product that is added to molten iron as a deoxidizer and an element additive in the steelmaking process to make steel have certain characteristics or meet certain requirements.

7. An intermediate alloy of iron and one or more elements, mainly used in iron and steel smelting.

8. In the iron and steel industry, all master alloys used for steelmaking, whether containing iron or not, are generally called ferroalloys.

9. It usually includes some pure metal additives and oxide additives.

10. It usually includes some pure metal additives and oxide additives.

1 1. Ferroalloy is used as deoxidizer to remove oxygen from molten steel during steelmaking. Some ferroalloys can also remove other impurities such as sulfur and nitrogen from steel.

12. alloying additives: according to the composition requirements of steel, alloying elements are added to steel to improve its properties.

13. Inoculant: It is added to molten iron before cast iron casting to improve the crystal structure of the casting.
