What are the factors that affect the absorption effect of anthracite recarburizer
- The quality of the recarburizer.
- The carbon content of the molten iron. Generally speaking, the lower the carbon content of the molten iron, the higher the absorption rate of the recarburizer. When the wC of the molten iron is above 3.6%, the carbon is difficult to increase again.
- The silicon content in the molten iron, the higher the silicon in the original molten iron, the greater the influence on the absorption of the recarburizer. Because silicon has a carbon emission effect, it reduces the solubility of carbon in molten iron.
- The plutonium content in the molten iron, the high content of plutonium in the original molten iron, is conducive to the absorption of the recarburizer.
- Charging and molten iron quality (whether it is severely oxidized).
- Blast furnace operation.
- The time and method of adding recarburizer.
- Furnace temperature adjustment Under normal production conditions, if the temperature of the molten iron is high, the carbon can be well dissolved in the molten iron to improve the carbon efficiency.
