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
Technical index requirements for calcined coal recarburizer：
1. Fixed carbon content requirements: generally required to be above 75%. The higher the fixed carbon content, the better the carbon increase effect and the stronger the adsorption capacity of the product.
2. Volatile matter content requirements: generally required to be below 15%. The lower the volatile matter, the better the calorific value and combustion ability of the product.
3.Ash content requirements: Generally required to be below 8%. Too high ash content will reduce the purity and carbon addition effect of the product.
4. Particle size requirements: Generally required to be 1-5 mm. The more uniform the particle size, the better the adsorption capacity of the product.
5. Stability requirements: The product must be stable and cannot change too much during transportation or storage, otherwise it will affect the carbon addition effect of the product.
