Details:
Aluminum-calcium balls are deep deoxidation steelmaking charge products developed by LSFerroalloy after many years of scientific research to reduce steelmaking costs. This product is a new composite material that integrates two super-deoxidizing elements, aluminum and calcium into one.
Both calcium and aluminum have a strong affinity with oxygen. Calcium, in particular, is a very active metal and a powerful reducing agent. It has a strong affinity not only with oxygen but also with sulfur and nitrogen. Aluminum is a traditional deoxidizer used in steelmaking, due to its strong affinity with O and the complete mutual solubility between Al and Fe. This also determines that the status of Al as an essential component in steelmaking deoxidation will be difficult to change for a long time. However, Al added to steel can easily form high melting point deoxidation products, which can worsen the molten steel’s fluidity and seriously affect the castability of the molten steel, thus posing a threat to the smooth operation of continuous casting production. Therefore, the amount of Al added during steelmaking deoxidation is limited.
Studies have shown that introducing strong deoxidizing element Ca into Al-containing deoxidizers can effectively denature the high melting point inclusions produced by deoxidation, thereby significantly improving the fluidity of aluminum-deoxidized molten steel. Therefore, aluminum calcium is an ideal product. Aluminum-calcium ball not only has a strong deoxidation ability, make the deoxidized products easy to float and discharge, but also improve steel performance and enhance steel’s plasticity and toughness.
In addition, the price of aluminum calcium balls is cheaper than pure calcium and pure aluminum. Aluminum calcium balls are easy to store, free of dust pollution, and they meet environmental protection requirements. Reducing costs is also a common demand of major steel companies.
