Abstract The main purpose of this paper is to discover the optimal roasting technology of hematite pellets burdened with semicoke by response surface methodology （RSM） to effectively solve the problem of high energy consumption of the hematite pellet roasting. The main influence factors and levels were confirmed by single factor test， the Box-Behnken design was used in systemically researching the effects of main process parameters on the compressive strength of semicoke-burdened hematite pellets. The multiple regression equation for predicting compressive strength was established. The parameters such as roasting temperature， roasting time， airflow volume， semicoke additive amount and their interaction were researched and optimized as well. The optimal values of the roasting process parameters were found at roasting temperature 1 292 ℃， roasting time 18.5 min， airflow volume 3.2 L/min and semicoke additive amount 1.5%. Under the condition of optimized process conditions， the compressive strength of semicoke-burdened hematite pellets was 2 578.3 N， very close to the response target value of 2 500 N. Experimental verification shows that the relative error between experimental and predicted values is simply 3.13%. The results show that the mathematical model is quite accurate and creditable.
