Abstract：Effect of acid-soluble aluminum on the property of the inclusions during the production process of LD－RH－LF－CC of tyre cord steel was investigated. It is found that Acid-soluble aluminum has a slight decrease trend during the refining process but drops rapidly during the continuous casting process. With the increase of Acid-soluble aluminum content, the Al2O3 content in the inclusions increases while the SiO2 content decrease, meanwhile the melting of inclusions increases. Using top slag with low basicity and low Al2O3 content in the refining process, strictly controlling the Acid-soluble aluminum within a range of 0.0005%-0.001%, as well as promoting floating upward of inclusions, will be benefit for low number and little size and plastification of the inclusions in steel.
