Study on Transformation of CaO-Al2O3-SiO2-MgO System Inclusions in ZGO6C113Ni4Mo Stainless Steel

This paper aims at generally studying on the inclusions of ZGG06Crl3Ni4Mo ultra-low carbon stainless steel used for large scale hydraulic turbine sets. On the basis of analysis the industrial test samples, thermodynamic software FactSage is used to study inclusions transformation process in CaOSiO2-Al2C<3-MgO system while stainless steel is been smelting. The results illustrate the inclusions melting points and plasticity variation law. The reasonable inclusions plasticity controlling area is found out in low melting point. The melting point is up to 1280°C While MgO weight concentration is 10% in CaOSiO2-Al2O3-MgO system, SiO2, A12O3 and CaO in inclusions are in weight concentration range of 50-70%, 10-20% and 10-40%, respectively. For purpose of gaining low melting point inclusions, silicon alumina radio in deoxidant should be controlled between 2-5 for ultra-low carbon stainless steel refining in industry.
