Low Carbon Ferro Silicon

Ferro silicon Description

Ferro silicon is an essential deoxidizer in the steelmaking industry. In torch steel, ferro silicon is used for precipitation deoxidation and diffusion deoxidation. Brick iron is also used as an alloying agent in steel making. Adding a certain amount of silicon to the steel can significantly improve the strength, hardness and elasticity of the steel, increase the magnetic permeability of the steel, and reduce the hysteresis loss of the transformer steel.

The Production Process of Low Carbon Ferro Silicon

With the development of purity steel production, the steel industry requires high purity of ferro silicon. The impurities in ferro silicon such as Ti, P, C, Al, Ca, etc.) need to be controlled strictly.

In the current production of high-purity ferrosilicon (including low-carbon ferrosilicon), carbides in ferrosilicon mainly exist in the form of SiC, and it is inevitable that some carbides enter the alloy during the smelting process, which will cause silicon There is too much carbon content in iron, which affects the quality of ferrosilicon and the selling price of ferrosilicon.

Therefore, it is very necessary to solve the defect of high carbon content in existing ferrosilicon.

The article shares a low-carbon ferrosilicon smelting method to solve the problem of high carbon content in existing ferrosilicon.

In order to achieve the above object, the technical solution adopted by the present invention is: a low-carbon ferrosilicon smelting method, which is specifically implemented according to the following steps:

Select quartz stone, reducing agent and silicon steel sheets as the concentrate raw materials, add them to the molten iron ladle, and heat and melt them

When the molten iron in the molten iron ladle accounts for one-third of its volume, weigh the slag-forming agent and add it to the molten iron ladle. The mass ratio of the slag-forming agent to the concentrate raw material is (1-3): 100;

Blow oxygen and compressed air from the bottom of the ladle

Remove slag from the surface of molten iron

Use a sampling rod to sample the molten iron until the color is bright and the processing is completed.
