This graphitized columnar carbon additive is a high-performance carbon additive material designed for high-quality ductile iron and gray iron casting. The graphitization treatment process gives the product an excellent crystal structure, with high carbon content and extremely low impurities such as sulfur and nitrogen, which helps to increase the carbon content of molten iron while avoiding adverse effects on material properties.Key indicators and specificationsCarbon content>95%, sulfur content<0.05%, nitrogen content<300ppmParticle size range of 1-5mm, columnar shape for easy feeding and dissolution controlPackaged in 25kg mother and child bags, supporting batch supplyApplicable scenarios and metallurgical advantagesThis product is particularly suitable for the production of ductile iron with strict sulfur content control, and can also be used for adjusting the carbon composition of gray cast iron. Its high fixed carbon content and good graphite morphology make it particular…
