<p>This control device (30) for converter furnace blowing equipment uses the exhaust gas flow volume and the component concentration to set parameters in a decarburizing oxygen efficiency equation model. Furthermore, this control device (30) for converter furnace blowing equipment adds the stirring gas flow volume as a variable in the decarburizing oxygen efficiency model equation, thereby reflecting in the decarburizing oxygen efficiency model equation the influence of the stirring gas flow volume during the blowing process. Thus, the decarburizing oxygen efficiency is calculated precisely, thereby enabling the carbon concentration in molten steel at the completion of the blowing process to be controlled precisely to achieve a target carbon concentration.</p> |
