Specifications Carbon Additive, Fixed Carbon 90-95%, Size 0-5mm, 0.5-5mm, 1-3mm, 1-4mm, 1-5mm 90% Min Introduction Carbon Additive is a silver-grey or black grain screening from anthracite or artificial graphite raw material. It's essential for production of high quality steel materials and also the raw materials for production of electrode paste. Application Carbon additive is mainly used in the foundry industry which can be a substantial increase in scrap consumption to reduce the amount of pig iron or no using iron It may substitute massively refinery coke or the stone grinds. Meanwhile its cost is much less than the refinery coke and the stone grinds. Carbon Additive may also use as the fuel for its calorific value. It may substitute burnt carbon massively.
