Frequently Asked Questions
Q: How does a low nitrogen recarburiser improve steel quality?
It reduces the overall nitrogen levels in the liquid steel, which prevents nitrogen brittleness, thereby significantly enhancing the toughness and plasticity of the finished steel products.
Q: What is the recommended addition temperature for BOF?
To ensure the recarburiser melts completely and functions effectively, it should be added to the Basic Oxygen Furnace (BOF) at temperatures between 1500°C and 1800°C.
Q: What is the typical dosage for this product in steel production?
While specific amounts depend on the required steel grade, generally the amount of low nitrogen recarburiser added should not exceed 1% of the total liquid steel volume.
Q: Is the production of graphitized petroleum coke environmentally friendly?
Yes, it is a green material. The production process is designed to avoid the generation of harmful gases, wastewater, and waste residues, reducing the overall environmental footprint.
Q: How do I ensure uniform carbon distribution in the melt?
Our product features highly uniform particle sizes. By adding it during the tapping process of BOF or EAF and utilizing the natural washing and stirring action of the liquid steel, you achieve a homogeneous carbon mix.
Q: Which ports are used for shipping these materials from China?
We primarily utilize Xingang Port and Qingdao Port in China to ensure efficient maritime logistics and timely delivery to our international clients.
