摘要
In order to improve the efficiency of slag and iron separationa new idea of "rapid reduction and carburization in lower temperature and adjustment of slag structure to realize the separation of slag ( solid) and iron ( molten) " is put forward.And the behavior of reduction and separation of iron and slag in carbon composite iron ore pellets has been investigated experimentally by the high temperature electric resistance furnace in simulated rotary hearth furnace process.And the influencing factors on the formation of iron nugget are discussed.Results show that the reduction of iron ore,carburization of reduced iron at lower temperature and the composition and quantity of slag are very important for producing iron nugget.Through optimization of process parameters,iron nugget can formed below 1 300 cC.This study can provide theoretical and technical basis on iron nugget production.
