Calcined coal recarburizer is made of finely washed anthracite after being calcined at 1200 degrees and then crushed, screened and packaged. It has the characteristics of high carbon content, low ash content and high absorption rate. Calcined coal is a very good recarburizer and is widely used in steel production. Calcined coal recarburizer is an indispensable part of steel production. Understanding its indicators and its impact on steel production will help improve production and quality.
Products Describe
Calcined coal is a very good carburizer and is widely used in steel production. It has many indicators, the most common ones are as follows
1. Fixed carbon: refers to the content of carbon that is not volatilized in calcined coal in the absence of oxygen. The higher the fixed carbon, the better the carburization effect.
2. Volatile matter: refers to impurities that are easily volatilized during heating, such as moisture, asphalt, etc. The lower the volatile matter, the more complete the carbonization process and the better the carburization effect.
3. Ash content: refers to the content of inorganic substances that cannot be volatilized in calcined coal. The lower the ash content, the better the carburization effect.
4. Oxygen content: refers to the content of oxygen in calcined coal. The lower the oxygen content, the better the carburization effect.
