Calcium aluminate (Desulfurizer) is a completely pre-melted material designed to meet the special requirements of steel makers. Secondary metallurgy has become a critical quality control step in the production of steel. A key feature for successful ladle metallurgy is slag control. Desulfurizer is specially designed for this purpose with the required chemical composition and physical properties. Synthetic calcium aluminate slags are already used with success in many steel co***nies.
Desulfurizer is not a by-product, but is a pure calcium aluminate of controlled composition. It is manufactured by complete fusion of bauxite and limestone in high capacity furnaces. This method ensures a homogenous product of constant composition.
Desulfurizer melts readily at liquid steel temperature. It forms an excellent cover slag, which protects the steel from atmosphere and limits the risks of reoxidation and nitrogen pick-up.
Desulfurizer allows the rapid constitution of an effective desulphurising slag with high capacity of absorption of no metallic inclusions.
This kind of calcium aluminate contains no fluorine: reduces attack on refractories, avoids environmental pollution.
Desulferizer is hard, stable and non dusty. It is easily stored and handled.
