PROCESS OPTIMIZATION BY RESPONSE SURFACE METHOD FOR SINTERING OF CHROMITE FINES BY MICROWAVE

摘要

Response surface method (RSM) based on mono-factor experiment was applied for the process optimization of sintering of chromite fines by microwave. In RSM analysis, effects of binder addition amount, sintering temperature and holding time on the compression strength and shatter strength of the sinter were examined. Results showed that the optimal values of the above parameters were determined as follows: binder addition amount of 1.90% (in mass), sintering temperature of 1153 □ and holding time of 16 min. Under the optimized conditions, the compression strength was 11155.8N and shatter strength was 95.6849%. The results show that the process was optimized by response surface methodology is stable and feasible, and provide a new way for sintering of chromite fines.
