High Quality Foundry Recarburizer for Metal Casting

This foundry recarburizer is a core cast iron auxiliary material and clay sand casting material, developed specifically for carbon element supplementation in the cast iron smelting process, which can effectively adjust the carbon content of molten iron and improve the mechanical properties of castings. The product uses high-quality graphitized petroleum coke as raw material, with fixed carbon content ≥98%, sulfur content ≤0.05%, nitrogen content ≤0.02%, and extremely low impurity content. When used with foundry compound sand and foundry sodium bentonite, it can reduce the adsorption of carbon elements in molten iron by the sand mold; when compounded with foundry coal powder, it can optimize the carburization efficiency; and when used with foundry starch, it can reduce dust during carburization. In cast iron production, adding 0.3%-0.8% by weight of molten iron can quickly increase the carbon content (increase by 0.1%-0.3%), with uniform carburization and no local carbon segregation, ef…
