Study on Key Technology of 38CrMoAl Steel Produced by BOF-LF-RH-CC Process

ZHAO Ke-wen1,2,HE Sheng-ping3,ZENG Jian-hua2,WANG Qian3,WANG Xin-hua1(1.School of Metallurgical and Ecological Engineering,University of Science and Technology Beijing,Beijing 100083,China;2.Iron and Steel Research Institute,Panzhihua Iron and Steel Group Co.,Panzhihua 617000,Sichuan,China;3.College of Materials Science and Engineering,Chongqing University,Chongqing 400044,China)  
High in 38CrMoAl(w) of 0.7%-1.1%) is liable to cause the nozzle blockage in continuous casting process.The composition of molten steel as well as the properties of molten slag changed obviously because of the slag-steel reaction,which will worsen cleanliness of steel.Based on the analysis of slag-steel reaction characteristics by thermodynamics calculation,reasonable component and control range were analyzed for the component optimization of LF refining slag and tundish powder.In order to maintain stability of mold fluxes after absorbing Al2O3,high basic and high glass phase mold fluxes were used.The industrial experiment shows that the goal of w(T[O])0.0012%,w([S])0.003%,good surface and subsurface quality of blooms can be achieved.
