Method for refining molten steel |
| abstract |
[PROBLEMS] To improve the component control accuracy with respect to a target carbon concentration and reduce the processing time while suppressing probe and gas costs in vacuum decarburization refining of ultra-low carbon steel using real-time monitoring technology. Thus, an object of the present invention is to provide a highly accurate and highly efficient melting method for ultra-low carbon steel. In a method of decarburizing molten steel to a very low carbon region of 100 ppm or less while continuously monitoring the carbon concentration in molten steel by vacuum decarburization treatment, a step of determining a continuous monitoring start time of the carbon concentration in molten steel; A method for refining molten steel, comprising a step of continuously monitoring a carbon concentration in molten steel from the start time and determining an end time of decarburization treatment.
