Abstract: |
The formcoke was prepared by using Shen Fu char as the raw material and pitch as the binder. The influence of particle size proportion of char、air treatment time and air treatment temperature on the compressive strength of formcoke was studied and also,the effect of the heating rate of carbonization, the final temperature of carbonization and the residence time of final temperature on the compressive strength of formcoke was investigated. The results indicated that at a certain particle size proportion,not only when the treatment temperature was 280℃ and the time was 1.5h,but when the heating rate of carbonization was 1℃/min ,the final temperature was 850℃ and the residence time was 1h,the max compressive strength of formcoke could be reached.
