Silicon-Carbon AlloyCasting and steelmaking

Silicon carbon alloys (SiC series) are silicon carbon composite alloys synthesized through special processes, specifically designed to optimize deoxidation and alloying processes in converter/electric arc furnace steelmaking. Its core advantage lies in the "silicon carbon equivalent integration":Multi effect substitution function: a single material can simultaneously replace ferrosilicon (FeSi), silicon carbide (SiC), and carbon additives (such as metallurgical coke), significantly reducing the complexity of auxiliary material procurement categories and inventory.The cost reduction mechanism is clear: taking SiC50 (typical composition: Si 50%, C 15%) as an example, adding 20kg of steel per ton can provide 10kg of silicon equivalent and 3kg of carbon equivalent. Compared with the traditional solution (silicon iron 75 #+98% C carbon additive), the alloy cost is reduced by 7-12% (based on the average raw material price in Q2 2024), and the auxiliary material burning rate is reduced by 1.5…
