Detail

Description:

Carburant/Recarburizer is additive used to increase carbon content in liquid steel/molten iron.

Classification:

Based on carbon form, Carburant/Recarburizer can be classified into graphitised and non-graphitised type: graphitised Carburant/Recarburizer include graphite electrode breaks/scraps/powder, graphitised petro coke, natural graphite, SiC and have absorption rate ≥ 90%, while, non-graphitised Carburant/Recarburizer include pitch coke, calcined petro coke, calcined anthracite, usual absorption rate about 75%.

Features of Graphitised Carburant/Recarburizer

High fixed carbon, Low S, P and N;
high temperature resistant, good thermal conductivity;
Quick absorption, high absorption rate, usually ≥ 90%;
Though it cost higher, overall utilization cost is lower;
Suitable for ductile iron and EAF steel making.
