| 摘 要： | Hot metal silicon content in blast furnace is a main parameter by which product quality is measured and energy utilization ratio of blast furnace is reflected.The precise predicted results of hot metal silicon content can be used to direct batch operation and smelting operation of blast furnace.And the purpose of reducing hot metal silicon content is realized.The equations of thermodynamics and dynamics were deduced based on the reduction mechanism of silicon. And the predicting model of hot metal silicon content was obtained.With this model and the calculation methods of blast furnace's materiel and energy balance,the predicting system of hot metal silicon content was programmed.Real materiel conditions and operation parameters wre inputted into the system.And predicted values of hot metal silicon content were gained.Compared with measured values the deviations of predicted values were small.So it is testified that this predicting system has credibility in practice.

| Abstract: | Hot metal silicon content in blast furnace is a main parameter by which product quality is measured and energy utilization ratio of blast furnace is reflected.The precise predicted results of hot metal silicon content can be used to direct batch operation and smelting operation of blast furnace.And the purpose of reducing hot metal silicon content is realized.The equations of thermodynamics and dynamics were deduced based on the reduction mechanism of silicon. And the predicting model of hot metal silicon content was obtained.With this model and the calculation methods of blast furnace's materiel and energy balance,the predicting system of hot metal silicon content was programmed.Real materiel conditions and operation parameters wre inputted into the system.And predicted values of hot metal silicon content were gained.Compared with measured values the deviations of predicted values were small.So it is testified that this predicting system has credibility in practice. |
