Under controlled temperature a high degree of reduction was achieved but at the expense of some 11 pellet degradation due to abrasion in the kiln Some of the product went to the British Iron and Steel Research Association BISRA at Sheffield for steel making in its electric arc furnaceThe hot gases generated during combustion raise the temperature of the kiln refractory lining bricks and as the kiln rotates at one revolution every two minutes the bed of iron sand char and limestone slides over hot refractory This elevates the product temperature still further to around 900 176 C at the exit
