Abstract：Pointing to a series of problems, such as poor deoxidation effect, poor slag fluidity, low slag basicity and difficult slagging in refining for deoxidated by used of silicon and manganese to molten steel applied to profiled billet continuous casting machine in Laiwu Steel, and through using aluminum deoxidizer which have the features of fast deoxidation and high efficiency, the deoxidation efficiency of molten steel was raised and the quality of molten steel was improved; through optimizing the function of refining slag system and adopting whole process controlling for inclusions the purity of molten steel was improved;through optimizing the treating effect of refining calcium and strengthening modification treatment for inclusions the castability of molten steel was raised and through strengthening the no-oxidation casting technology for molten steel deoxidated by aluminum in continuous casting machine the clogged on nozzle was avoided. The implementation of above measures can ensure the smooth operation of aluminum deoxidation process of profiled billet continuous casting machine, raise the quality of billet and reduce the production cost.
