Melting & Furnace Raw Materials

CARBURIZERS – CARBON ADDITIVES

The best source of carbon for increasing & fine-tuning carbon pick-up in molten metal in case of SG iron, due to the low Sulphur content which is normally below 0.1%. Fixed Carbon 95 – 99%.

Helps increase carbon content in Molten metal & is primarily used in the production of Cast Iron. Sulfur content is between 0.8 to 1.5%. Fixed Carbon 92 – 98%.

Coconut shell charcoal is used as carbon additive in Steel manufacturing and SG Iron castings for its near zero sulphur content and fixed carbon of 78 % which gives more carbon recovery. This option is comparatively cheaper but availability is limited.
