主　　题：iron ore sintering assimilation characteristic resistance method interface 

摘      要：Resistance in iron ore undergoes a sharp change of up to several orders of magnitude when the sintered solid phase changes to liquid *** view of the insufficiency of existing assimilation detection methods,a timing-of-assimilation reaction is proposed,which was judged by continuously detecting the changes in resistance at the reaction *** of pole position and additional amounts of iron ore on assimilation reaction timing were *** results showed that the suitable depth of pole groove was about 2 mm,and there was no obvious impact when the distance of the poles changed from 4 to 6 mm,or the amount of iron ore changed from 0.4 to 0.6 *** temperature of sudden change of resistance in the temperature-resistant image was considered to be the lowest assimilation temperature of iron *** accuracy of this resistance method was clarified by X-ray diffraction,optical microscope,and scanning electron microscope/energy dispersive spectrometer(SEM/EDS)analyses.
