The carbon and graphite materials are non-metallic solid materials dominated by carbon, wherein the carbon are substantially composed of non-graphitic carbon, and the graphite materials are substantially composed of graphitic carbon. Sometimes carbon and graphite materials are collectively referred to as carbon materials.
With the rapid development of China's economy, the demand for special steels has become more and more widespread in all walks of life, therefore steel making technology in electric arc furnace turn to rapid development. Large-capacity ultra-high-power electric arc furnaces and large-scale furnace refining technologies have become the mark of modern steel industry.
