Si-ba-ca is a new steelmaking deoxidizer and casting inoculant. It also has good desulfurization and dephosphorization ability, can change the performance of non-metallic inclusions in steel, and can spheroidize and refine steel. Inclusions reduce the harmful effects of non-metallic inclusions. Accurate determination of calcium strontium content in silicon germanium alloy inoculants and spheroidizing agents is important for both production process and product quality. Reference materials for the determination of calcium strontium content, mostly by complexometric titration method for the determination of calcium, barium sulfate gravimetric method for the determination of strontium, the determination of a variety of reagents used, and the analysis cycle is long, the operation is cumbersome, can not meet the needs of production testing. After many experiments, this paper proposes: nitric acid, hydrofluoric acid dissolved samples, ammonia-copper reagent to separate matrix iron and impurities such as aluminum, manganese, titanium and other interference elements. The filtrate was combined to determine the calcium and strontium content under appropriate acidity and indicator conditions. The method has achieved good results after repeated tests and production inspection applications, and has improved the speed of analysis and inspection and the accuracy of analysis results.
