| Abstract: | The relationship between the foam height and time is measured for foaming processes originated from reducing TiO 2 in the synthetic blast furnace slag under different condition. The foam behavior parameter is determined by means of the experimental results and the modified computer program. In this way, this foaming process can be described quantitatively and the influence of TiC content in original slag and the TiC in the reducing TiO 2 on the foaming processes can be analyzed. The reason is determined why more times foaming phenomenon can take place in slag containing high TiO 2. |
