<p>PURPOSE:To control carbon component in steel into a narrow range and improve the measuring precision in the controlling/measuring precision of the carbon component. CONSTITUTION:In the controlling/guaranteeing method of carbon component in steel, the carbon component at the time of ladle refining is regulated on the basis of the analyzed value by combustion-infrared absorbing method of a pin sample in the process for casting a melted steel through ladle refining and, then, the carbon component value under ladle is also guaranteed by the analyzed value by the combustion-infrared absorptive method of the pin sample.</p> |
