It is manufactured of highly cleaned natural graphite. ACTION KARBURIT NL is dissolved in melt and thus the carbon content in alloy with iron is increased. INSTRUCTIONS FOR USE KARBURIT NL is applied for carburization of melt in crucible induction furnaces or in ladles. It enables to manufacture quality nodular graphite cast iron, where a very low content of phosphorus and nitrogen is produced. Before melting the needed amount of KARBURIT NL is charged into the induction furnace together with the burden. In calculating the burden a 90 % yield of KARBURIT NL is taken. Since the dissolution rate of carbon in iron depends on contents of silicon and phosphorus, those two elements are alloyed only after the completed melting. Dissolution rate is proportional to the melt temperature. PACKING KARBURIT NL is packed in big bags at cca 1000 kg each, on wooden pallets, or in natron bags at 25 kg wrapped with foil on the pallet. STORING AND TRANSPORT KARBURIT NL must be protected against atmospheric precipitation’s in transport and storing. According to the European regulations for international road transport of dangerous goods, KARBURIT NL is not a dangerous substance.
