High Carbon Silicon Carbon Alloy Si55C15

We produce Si55C15 at our plant in Anyang, Henan. It's a composite deoxidizer and carburizer - one material that delivers both silicon and carbon to the melt. Instead of stocking ferrosilicon and a separate carbon raiser, the furnace crew adds one alloy and gets both effects. We make it from high-purity carbon powder, silicon carbide powder, and metallic silicon powder, processed into lumps, briquettes, or powder to match the customer's feeding setup. The material has high density and consistent chemistry from batch to batch, and it runs without issues in converters and electric arc furnaces alike.

The big advantage of Si55C15 is that it simplifies the furnace operation. One alloy handles two jobs - deoxidation and carburization. Recovery on both silicon and carbon sits above 95%, so there's not much material lost to slag. Customers who switched from buying ferrosilicon and carburizer separately tell us they save around 5% to 10% on their alloy cost per ton of steel. The chemistry stays consistent lot to lot, and the material feeds through hopper systems without bridging or jamming. For a steel mill running tight margins, that kind of reliability matters a lot.

Standard packing is 1 MT jumbo bags with material sized 10-50mm. If your feeding system needs something different, we also supply 0-5mm powder, 1-10mm granules, and briquettes. Each bag carries a label with the heat number, grade, and net weight so the receiving crew can check it at a glance. We've customized packing for plenty of buyers - different bag sizes, palletized loading, whatever works with your handling equipment.

We've been producing silicon alloys in Anyang, Henan since 2010. Our factory sits in the Longan District - right where most of China's ferroalloy capacity is concentrated, so raw materials are close and costs stay reasonable. We run about 8,000 MT per month across all grades. Every order goes through SGS inspection before it leaves, and the COA ships with the material. We load from Tianjin and Qingdao ports, typically within 7 to 10 days after the order is confirmed. Our main markets are Turkey, Egypt, Saudi Arabia, and across Southeast Asia and East Asia. If you'd like to visit the plant, just send us a note - we'll arrange the whole thing.

Q: Can Si55C15 really replace ferrosilicon and a carburizer together?
A: Yes, that's exactly how it's designed to work. One addition gives you both deoxidation and carburization in a single step. No need to stock two separate materials.

Q: What kind of recovery rate should I expect?
A: Both silicon and carbon recover above 95% under normal furnace conditions. You get most of what you pay for into the bath, not into the slag layer.

Q: Can you adjust the sizing?
A: Of course. Standard is 10-50mm, but we regularly produce 0-5mm, 1-10mm, and other ranges. Tell us what your feeding system needs and we'll match it.

Q: Which markets do you serve?
A: Turkey, Egypt, Saudi Arabia, and Southeast Asia are our largest markets. We can arrange freight to most ports worldwide from Tianjin or Qingdao.
