process of iron reduction in tunel kin and rotary kiln

In the standardSL/RN process,iron ore,coal, and dolomite or limestone as desulfurizing agent are charged into arotary kilnand heated up by a countercurrent gas flow. Heat is generated by the controlled combustion of volatiles from the coal and surplus CO from the charge.
