| Abstract: | The present paper describes how to properly control the chemical compositions of the liquid metal and reduce the content of inclusions in steel in the process of refining Q195L steel in the converter. It's concluded that quality billets for drawing wire purpose can be produced by controlling the chemical compositions of the steel; appropriately selecting deoxidizer and feeding amount of the deoxidizer per ton steel; controlling the bottom argon bubbling time and killing time;properly controlling the residual oxygen in steel and over heat of steel in the tundish and adopting protective casting in the whole process. |
