Our advantages: 1, High 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; 3, Fine classification - Various product category, to provide customized carbon raising scheme 4, Cost-saving - Reduce the usage amount of iron, increase scrap consumption, and save raw material cost. Usage: For 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. For greater than 5 T furnace: - mix proper carbon additive with charging material as suggested first, - and then along with the increase of charging material gradually, - that is, before the molten metal rising up to about 2/3 height of furnace, - all carbon additive shall be added. It guarantees sufficient melting & absorbing time before molten metal out, and improves the absorption of carbon.
