How to quickly identify the quality of petroleum coke recarburizer? Shengchi Ferroalloy will give you a brief description:
1. Ordinary calcined petroleum coke recarburizer, because it has not been calcined at a high temperature, the calcining temperature may be low and the time is short. The nitrogen content is generally around 9000 ppm, and the sulfur content is also high. No clear marks can be drawn on white paper.
2. The high-temperature calcined petroleum coke recarburizer is called semi-graphitized recarburizer. The nitrogen content is 300-500ppm, and the sulfur is much lower than the former. Clear marks can be left on white paper.
