随着高炉大喷煤操作的不断改进，铁水中的含Si量有逐渐增加的趋势。这一现象已无法用传统的预测模型来解释，因为它不能区分焦炭及煤粉对铁水中含Si量的不同影响。关于煤粉中SiO的气化反应，则在还原气流条件下，对压实装在坩埚中生成Si... 详细信息

随着高炉大喷煤操作的不断改进，铁水中的含Si量有逐渐增加的趋势。这一现象已无法用传统的预测模型来解释，因为它不能区分焦炭及煤粉对铁水中含Si量的不同影响。关于煤粉中SiO的气化反应，则在还原气流条件下，对压实装在坩埚中生成SiO（气），的过程进行了基础试验。此外，对高炉中发生的Si转移，测定了大喷煤条件下煤粉中SiO（气），的生成速率，并研究了煤粉对铁水中[Si]的影响。进而可以在实际炉子操作中测出与煤种变化有关的铁水中[Si]的变化量。

A three-dimensional fixed offshore platform in deep water modeled by the finite element method is studied in this paper. Analysis of the dynamic response of the MDOF structure is realized taking the non-linearity of the wave drag force and the wave-structure interaction into account. The structural response statistics, which have Gaussian distributions, are used to evaluate the vibration effect of the structure without TMD and with TMD. And an optimal method to design TMD controlling the first mode of the multi-mode structure is proposed. Moreover, the probabilities of occurrence of sea states at the platform site are considered for prediction of the long-term effect of a TMD. Simulation results demonstrate that the long-term effect of a well-designed TMD is good and the practical use is possible due to the good stability of its optimal parameters under different sea states.
