One Of High Level Alloys Ferro Silicon Powder

Silicon is added on the surface of ordinary silicon steel plate by composite electroplating of iron and silicon powder and iron and ferrosilicon powder. The effects of composite plating process and powder particles on the amount of silicon added to the composite layer were studied. The results show that with the increase of current density, the plating speed accelerates, but the silicon content in the composite coating decreases gradually. At the same time, the refinement of the composite particles and the increase of the particle content in the plating solution have a significant effect on improving the silicon content in the composite coating.

1.A ferrosilicon powder remelting process, which is characterized by: selecting one set of normal production silica hot furnace; Prepare the molten iron refining bag for bottom blowing oxygen, evenly introduce air into the bottom blowing bag before tapping, and blow oxygen and compressed air into the bottom of the bag according to the ratio of oxygen to air 2.0~12M3/h:1.0~6M3/h when the molten iron flows into the bottom blowing ladle, and add a special flux to the bag, the composition of the special flux is quartz sand, quicklime, oxide scale, fluorite, each component is 40~44:28~35:1~5:13~20 by weight, and the amount of flux is 3wt% of the amount of molten iron ～5wt%; Then add ferrosilicon powder to the boiling melt in the bag, and the amount of ferrosilicon powder is 5wt%~10wt% of the molten iron. It effectively saves energy, prevents pollution, improves the product production rate, reduces costs, and improves the enterprise economy.
