The difference of ferrochrome powder with different carbon content

First, the carbon content of high-carbon ferrochrome powder is 4-10%, the content of medium-carbon ferrochrome powder is 0.5-4%, the content of low-carbon ferrochrome powder is 0.15-0.5%, and the content of micro-carbon ferrochrome powder is 0.15%.

Second, the smelting methods of micro-carbon ferrochrome powder include electric silicon thermal method, thermal blending method and so on. The key is to improve the oxidation resistance and corrosion resistance of the steel, so that the surface of the steel produces a layer of air oxidation plastic film with strong adhesion in the air oxidation atmosphere, and then the air oxidation terminates or the air oxidation rate decreases. Micro - carbon ferrochrome powder is used in the manufacture of stainless steel plates, wear - resistant and heat - resistant steels.

Third, the scope of application of high carbon ferrochrome powder is:

1, used for high carbon content of commodity circulation bead steel, alloy steel and spring steel aluminum alloy agent, improve the cutting performance of steel, improve the wear resistance and strength of steel.

2, used as a preservative for pig iron, improve the wear resistance and hardness of pig iron, in addition, make pig iron has excellent temperature resistance.

3. It is used for the production and manufacture of Si-Ni alloy and vertical, low and micro carbon ferrochrome powder and raw materials containing magnesium.

4, used for electrolytic salt water production of metal chromium containing magnesium raw materials.

5, used for oxygen blowing smelter stainless steel plate raw materials. Smelting process of high carbon ferrochrome powder: smelting method of high carbon ferrochrome powder has iron smelting blast furnace method, heating furnace method, low temperature plasma method, melting reduction method, etc.
