improve the casting quality and reduce the cost. And, it has stable carbon-silica ratio, with low content of Al, P, and inert gas.
Usage
1-5mm silicon carbide is added in the early stage of electric furnace smelting. When 1/4-1/3 of molten iron appears in the furnace, it is added, and then the scrap is covered and smelted.
In this way, the scrap steel can press the silicon carbide into the molten iron, so that the silicon carbide is not easy to float, dissolves and diffuses in the molten iron for a long time, and the absorption rate is high.
