w(Al_2O_3)/w(SiO_2)对烧结液相生成的影响研究

Study on influences of w(Al_2O_3) /w(SiO_2) on sintering liquid phase generation

通过研究w（Al_2O_3）/w（SiO_2）对烧结液相生成的影响及分析实际烧结生产中烧结矿w（Al_2O_3）/w（SiO_2）不同范围对转鼓强度的影响,得出烧结配料w（Al_2O_3）/w（SiO_2）控制在0.300~0.355有利于烧结矿质量的提高。在此基础上,进一步探讨了马钢烧结配料w（Al_2O_3）/w（SiO_2）应该控制的水平及3个炼铁总厂烧结矿现w（Al_2O_3）下w（SiO_2）适宜的控制范围,并提出了针对性的调整建议。

The influence of w（Al_2O_3）/w（SiO_2） on the generation of sintering liquid phase was studied and the influence of the range of w（Al_2O_3）/w（SiO_2） on the drum strength of sinter in actual sintering production was analyzed. The results showed that controlling the range of w（Al_2O_3）/w（SiO_2） in sintering ore burdening between 0. 300 and 0. 355 was of benefit to improving the sinter quality. Based on the result,the sinter-burdening-control level of w（Al_2O_3）/w（SiO_2） and the appropriate range of w（ Si O2） to be controlled under the available w（ Al_2O_3） in three general ironmaking plants of Masteel were further discussed,and then pertinence adjustment recommendation was also put forward.
