The S entering into pellet with concentrate is pyrite, with coal powder are iron sulfide, sulphate and organic sulphur, when reducing, S existing in pyrite, iron sulfide and organic sulfur come into gas phase, then been absorbed by fresh Fe and liberate out of pellet, combined with CaO existing in outside of the pellet to form CaS finally, sulphate will remain in DRI.

当还原温度高于在铁碳相图中的最低液相线温度1147~1153℃时，渗碳作用导致DRI外壳熔化，这层致密的熔融外壳起到热态直接还原铁的防氧化作用。低于这个温度将有助于还原和脱硫。
