What is ferrochromium?

Ferrochrome is mainly composed of chromium and iron elements. The production methods of ferrochrome are divided into oxygen blowing method and solid decarburization method in vacuum state. Ferrochrome is mainly used in the steelmaking industry. This is mainly because of the Chromium can effectively improve the properties of steel. Ferrochrome can be divided into multiple types based on carbon content;

Among them, high carbon ferrochrome has an internal carbon element of up to 4%~10%, medium carbon ferrochrome has a carbon content of 0.5%~4%, low carbon ferrochrome has a carbon content of >0.15%~0.5%, and the higher content of high carbon Ferrochromium is called carbon ferrochromium, while ferrochromium with low carbon content is called refined ferrochromium. Refined ferrochromium is an iron alloy product with high chromium content;

What are the advantages of ferrochrome?

Ferrochrome products have long been purchased by manufacturers in large quantities simply because of the unique advantages of ferrochrome. So what are the advantages of ferrochrome?

1. Ferrochromium has the advantage of increasing the oxidation resistance of steel during the steelmaking process.

Adding ferrochromium during the steelmaking process can effectively increase the oxidation resistance of the steel. The chromium element in ferrochrome can effectively protect the steel and slow down its oxidation rate, thereby increasing the oxidation resistance of the steel and extending the service life of the steel. advantage;

2. Putting a proportion of ferrochromium into the molten steel has the advantage of effectively improving the corrosion resistance of the steel.

During the steelmaking process, adding a certain amount of ferrochromium in proportion to the element content in the molten steel can effectively improve the corrosion resistance of the steel. The chromium element in ferrochrome can effectively adhere to the surface of the steel to provide an insulating layer. Advantages of corrosion resistance.

3. Ferrochrome has the advantage of effectively improving the hardness and wear resistance of steel.

Ferrochromium is generally used in today's steelmaking process. The main reason is that ferrochrome can effectively improve the hardness and wear resistance of steel. The chromium element in ferrochrome is not easy to combine with oxygen, so it can effectively improve the oxidation resistance of steel. In addition, ferrochromium can also purify steel impurities and improve the hardness of steel.
