By using the carbon additive from Duratight in producing casting, it can increase the used quantity of Scrap steel and reduce the quantity of Scrap iron, or use no Scrap iron at all, Duratight carbon additive has follows properties: high absorptive character,   no residue will be left, save production cost.

1,Usage used to improve the Carbon content in steel-melting and Ductile iron foundry

2,Characteristicahigh carbon, low sulfur, with stable effect for improving the carbon content, high absorptivity of carbon.

3,apply Used in electric furnace steel smelting and cast-iron for improving the carbon content

4,Grain size  normal size0.3-3mm 1-4mm1-3mm3-5mm,3-8mm,5-10mm or per as customers special requirement.
