In order to meet the strict requirements of inclusion and cleanliness for high quality cord steel,top slag composition and refining process had been studied through predication and industrial practice.The results show that the inclusions can meet the requirements of plasticity at lower melting temperature when the tap slag basicity (CaO/SiO2) and Al2O3 content are controlled at about 1.0 and in the range of 6%~8%,respectively. Compared with the process of DeS-LD-LF-Ar-CC,the process of DeS-LD-LFRH-CC can lead to inclusion meeting requirements of plasticity and further reducing content of T[O] and [N],and thus improve the cleanliness. The average wire broken ratio of cord steel products is 0.47 time per ton and the fatigue lifetimes reached over 20,000 cycles.
