| Abstract: | The technology for controlling the content of total oxygen in wire rod for cord steel is studied with regard to smelting by converter, refining by LF and continuous casting process and then the integrated control technology with such characteristics as tapping with high carbon from the converter, carrying out plasticization of inclusions in steel, treating molten steel by performing weak argon blowing, raising the weight of molten steel in tundish during tundish-changing in con- tinous casting and protective casting is developed. As a result, the content of total oxygen in wire rod for cord steel produced by Angang is controlled in the range from 0.001 5% to 0.002 0%. |
