Choose high-quality sponge coke as the raw material, with porous particle morphology, fast decomposition rate, and high absorption rate of 90%.Negative electrode material accessory product, after high-temperature treatment, the sulfur and nitrogen content is relatively stable.The particle size is uniform and concentrated, and the carbonization rate is stable.
Product Parameters:
Model | Fixed carbon | Ash | volatile matter | Moisture | Su | N | Granularity |
JDZ-01-02 | ≥99% | ≤0.3% | ≤0.5% | ≤0.1% | ≤0.03% | ≤100ppm | 0.2-1.45mm |
The metallurgical characteristics and advantages of Jiuding instant carbon additive:
（1）The raw material is high-purity graphitized petroleum coke, with a stable nitrogen content controlled within 100ppm.
（2）It features uniform particle size, high particle concentration, low impurity content, rapid absorption rate, and high absorption efficiency.
（3）It can effectively compensate for carbon burnout in induction furnaces to reduce internal porosity defects and surface shrinkage defects in castings.
（4）It effectively increases the nucleation ability of the original molten iron, increases the amount of graphite particles, improves the graphite grade, and improves the mechanical properties of the castings.
（5）It should be added into the stream when the tapping reaches 1/4 to 3/4 of the total volume, or it can be added all at once into the tapping ladle when the tapping reaches 1/4 to 1/2. The recommended addition amount is 0.02% to 0.04%.
