Abstract Due to the insufficient understanding of the influencing factors of calcium treatment, the effect of calcium treatment in different enterprises is different. In order to improve the precision of calcium treatment,influencing factors and influencing rules of the effect of calcium treatment of Al-killed steels are briefly described in the current work from the composition of molten steel and slag, the types and carriers of calcium alloys, the operation of calcium treatment process and the timing of calcium treatment. Many factors are affecting the effect of calcium treatment, and the main factors different enterprises facing are also different. The results can help steel enterprises to understand the main influencing factors of their calcium treatment operation, and then realize the precise control of calcium treatment, which improves the product quality and reduces the production costs.
