| Abstract: | The effects of different coal ratios and reaction temperatures on silicon content in hot metal were studied under the condition of high powder coal injection (PCI) ratio in laboratory. The samples of coke taken from tuyere were analyzed by chemical methods. According to the remnant silicon dioxide in different samples, the effect of PCI ratio on silicon content in hot metal was studied in tuyere area. The results can not only certify the traditional theory, but also explain the relation between high PCI ratio and low silicon. |
