Frequently Asked Questions
Q: How does the low nitrogen recarburiser improve steel quality?
By maintaining nitrogen levels below 300 PPM, it reduces nitrogen brittleness, which directly increases the toughness, plasticity, and overall structural durability of the steel product.
Q: What is the recommended dosage for this product in liquid steel?
Generally, the amount of low nitrogen recarburiser added should not exceed 1% of the liquid steel, depending on specific product requirements and carbon targets.
Q: At what temperature should the recarburiser be added?
To ensure complete melting and optimal carbon absorption, it should be added into the BOF at a temperature range between 1500°C and 1800°C.
Q: Can this product be used in both BOF and EAF?
Yes, it is specifically designed for addition during the tapping process of both Basic Oxygen Furnaces (BOF) and Electric Arc Furnaces (EAF).
Q: What packaging options are available for international shipping?
We offer 1-ton Jumbo Bags, as well as 10kg or 25kg small bags packed within Jumbo Bags for easier handling and transport.
Q: Why is uniform particle size important in iron alloy smelting?
Uniform particle size prevents clumping and ensures the material dissolves evenly in the melt, leading to a consistent carbon distribution and avoiding quality defects in the steel.
