ferrochromium

 

 

Ferrochromium is an alloy made by mixing chromium and iron. FeCr can be divided into 4-8% high-carbon ferrochromium, 0.5-4% medium-carbon ferrochromium, 0.15-0.50% low-carbon FeCr, 0.06% micro-carbon ferrochromium, ultra-micro-carbon FeCr (C < 0.03%), silicon chromium alloy, FeCr nitride and so on according to its carbon content.

The less carbon content in chromite, the more difficult smelting, the greater the energy consumption, the higher the cost. Chromium cast iron with 4% or more carbon content is usually used to cast ball bearing steel and automobile parts. FeCr containing about 5% chromium can be used as an alloy transfer agent.

Uses of Ferrochromium
(1) In the metallurgical industry, FeCr alloy is an important raw material for the production of chromium-iron alloy and chromium system. Chromium-iron alloy is a special kind of steel which is characterized by high strength, corrosion resistance, wear resistance, high temperature resistance and oxidation resistance. Chromium metal is used to melt special alloys including cobalt, nickel and tungsten. These special steels and their alloys are essential raw materials for manufacturing weapons, missiles, rockets, and ships.
(2) In refractories, FeCr is mainly used in the production of chrome bricks, chrome-magnesium bricks and other special refractories.
(3) In the chemical industry,FeCr is mainly used in the production of sodium dichromate, which is utilized in the production of other chromium, such as pigments, textiles, electroplating, leather tanning and other industries, and also as a catalyst and catalyst. Chrome ore is mainly sold through three routes: the metallurgical industry, the refractory industry and the chemical industry.

Advantages of Ferrochromium

1. FeCr in the steelmaking process has the advantage of increasing the antioxidant property of steel.

Add ferrochrome to steel, can effectively improve the antioxidant performance of steel, where the chromium element can play a good protective role, slow down the oxidation rate of steel, improve the antioxidant property of steel, improve the service life of steel.

2. The proportion of FeCr in steel has the advantage of effectively enhancing the corrosion resistance of steel.
In the production process, according to the elemental content of steel in the appropriate amount of ferrochrome, can effectively improve the corrosion resistance of steel, chromium in the chromium can form a layer of insulation on the surface of steel, has good corrosion resistance.

3. FeCr has the advantage of effectively enhancing the hardness and wear resistance of steel.
Today's steel production process, generally add fecr, this is because FeCr can improve the hardness and wear resistance of steel, FeCr in the chromium is difficult to combine with oxygen, so it can improve the antioxidant properties of steel, but also purify the impurities in the steel, improve the hardness of steel.
