Coarse Graphite Carburizer 3-8mm

Introduction There is a common assumption that finer carburizer dissolves faster and is therefore better. In a cupola or a deep ladle the opposite is often true: fine material is carried out with the blast or trapped in the slag before it ever reaches the metal. Coarse granules stay where they are put and keep releasing carbon through the whole treatment.   What it is Graphitized petroleum coke, crushed and screened to a 3-8 mm cut. The coarser fraction dissolves over a longer period, which suits furnaces with a tall bath and a long residence time, and survives the air blast in a cupola where a 1 mm particle would simply leave with the off-gas.   Key specifications - Fixed carbon: 98% min - Particle size: 3-8 mm standard; other cuts on request - Ash, volatile matter: low; per lot certificate - Sulphur and nitrogen: low-sulphur grade available - Packing: 25 kg bags, 1,000 kg bulk bags   Where it fits - Cupola melting, where fines are lost up the stack - Large ladles and deep baths with…
