What are the advantages of silicon carbon alloys

Advantages of silicon carbon alloys:

Treating the original molten iron with silicon carbon alloy can significantly change the crystallization characteristics of molten iron, reduce the tendency of white mouth, and eliminate anti-white mouth. The production of white mouth tendency anti-white mouth is related to the formation of nuclear power of graphite, and it can be considered that silicon carbon alloy has played a role in the treatment of raw molten iron. The weakening of the usefulness of the silicon carbon alloy after the post-incubation treatment may be due to the overlap of the use of the post-gestation graphitization and the silicon carbon alloy. Nevertheless, it is foreseeable that the silicon-carbon alloy treatment will weaken the dependence of the solidified tissue and the post-incubation treatment, and will improve the stability of the microstructure properties. Silicon carbon alloy is different from silicon iron, silicon carbon alloy has a high melting point, and then the molten iron is not melted but slowly melted, in the melting process does not provide silicon atoms to the surrounding liquid phase also provide carbon atoms. When the silicon-carbon alloy is melted in molten iron, it forms a full range of fine graphite particles around it, which, although re-melted, form full-scale carbon atom groups that are the basis for the later formation of graphite-shaped nuclei.

Silicon carbon alloy can refine the grain, improve strength, enhance toughness, anti-leakage, so the garbage rate is reduced, the resoldering rate is reduced, and the silicon carbon alloy is easy to use, bag packaging, easy to keep. It is easy to grasp the amount of application so that more scrap steel can be added to get the ideal casting, and the silicon carbon alloy can also replace the 75-gauge ferrosilicon, reducing the amount of carburizing agent and reducing the casting cost.

The above are some suggestions, I hope to help you!
