After many years’ research and development, with customers’ experience, Duratight Carbon additives get the features of high carbon, low sulfur, low nitrogen and less impurities. Duratight carbon additive can be used in foundry scope to promote the techniques, also to promote the steel quality in steel-melting. N ow this product is widely used by many big auto manufacturers and spare parts in vessel making factories, to improve the carbon content in cylinder body, cylinder cover, etc. Duratight carbon additive can improve the machinery performance of the products.Specification as follows:ItemNo. Fixed Carbon (min)Sulfur(max)Ash(max)V.MMoistureGrain size(90%)Nitrogen(max)DT-CA-0298.50%0.50%0.80%0.80%0.50%1-5MMN/ADT-CA-0699.00%0.30%0.50%0.50%0.50%1-5MM1000divdivMDT-CA-0998.50%0.05%0.80%0.70%0.50%0.3-5MM300divdivMDT-CA-1095.00%0.30%3.50%1.50%0.50%1-4MM700divdivMDT-CA-1199.00%0.03%0.50%0.50%0.50%0.3-5MM300divdivMDT-CA-1280.00%0.10%16.50%3.50%2.00%1-5mmN/ABy using the carbon additive from Duratight in producing casting, it can increase the quantity of scrap steel and reduce the quantity of scrap iron, or use no scrap iron at all. Duratight carbon additive has following features: high absorptivity, no residue and cost-saving.1. Usage: used to improve the carbon content in steel-melting and ductile iron foundry.2. Characteristics: high carbon, low sulfur, few harmful ingredients, high absorptivity of carbon, with stable effect on improving the carbon content.3.
