1. Ductile iron carbonizer is generally selected graphitization carbonizer high-carbon low-sulfur products, the sulfur content requirements are more stringent, generally controlled in: S: ≤ 0.1%, S: ≤ 0.05%
2. The main technical index difference between gray iron carbonizer and ductile iron carbonizer lies in the control of sulfur, and the general index requirement is S: ≤0.5%.
3. cast steel (steelmaking) carbon enhancers are more complex, generally large steel mills in accordance with different steel will choose a variety of carbon enhancers, but the general material for the calcined coal and graphite particles or graphite balls, there are natural graphite crushed, the content of 75% -99% varies.
Fixed carbon and ash are the two opposing parameters in carbonizer, and they are also the two important parameters affecting the efficiency of carbonization. If the fixed carbon content in the carbonizer is high and the ash content is low, the carbonizing efficiency is high, and vice versa, the carbonizing efficiency is low.
