Product Properties 1High purity - Control the consistency of raw material from the mine resource. - Introduce automatic whole-process equipment to ensure product consistency. 2 Good performance - Increase globular graphite amount in the nodular cast iron significantly to promote the graphitization; - Increase the graphite crystal nucleus of molten iron, refine graphite in the matrix for more uniform distribution; 3Fine classification - Various product category, to provide customized carbon raising scheme 4Cost-saving - Reduce the usage amount of iron, increase scrap consumption, and save raw material cost. How to use 1For 1-5 T furnace: - while a small amount molten iron in the furnace, - or with some molten iron remained, add the carbon additive one-time, - then add the other material. which can make carbon additive fully absorbed. 2For greater than 5 T furnace: - mix proper carbon additive with charging material as suggested first,
