Carburizer for Fine-tuning Process
The carburizer for fine-tuning process is mainly used to make up for the insufficient carbon equivalent when the molten iron is melted and enters the pouring process. At this time, the carbon equivalent of the molten iron measured by the carbon-sulfur analyzer does not exceed 0.1% from the technical requirement value. Use the fine-tuned carburizer particles It has the characteristics of low density and fast disintegration and absorption. It can quickly replenish the carbon element of the molten iron. Its particle size is generally controlled at 0.2-1mm, the sulfur content is less than 0.05%, and the absorption rate can reach 60% within 5 minutes.
Fine-tuning the particle size of the carburizer is the key to slightly adjusting the carbon equivalent of the molten iron in a short time (usually within 5 minutes). The smaller the particle, the faster the heating, the faster the disintegration and absorption, and the faster the carbon replenishment. However, it should be noted that the powdery material in the particles should not be too much, otherwise it will easily float on the surface of the molten iron, and will easily burn too much, which will affect the absorption. Practice has proved that the particle size of 0.2-1mm is the most appropriate fine-tuning process.
