An attempt has been made to quantify the effects of the variables on strength in sintering of iron ore/blue dust received from Bailadila, NMDC. For this, the method of design 2n factorial experiment is used to obtain a response surface equation. Results indicate if the coke breeze increases in the range of variation of the variable in sintering, the strength increases but strength decreases when moisture increases from lower level to higher level. Blue dust does no effect the strength. The optimum levi (-4: variables for the maximon strength of the sinter produ(A is determined by the method of hexagonal design of experjnent. The results indicate that for a basicity of 1.9 an acceptable quality of sinter can be produced. Blue dust amounting to 40.0% of all the iron ore fines taken together can be incorporated in the raw mixture without imparting the strength of the finished sinter.
