The skin of a ferronickel rotary kiln at high temperature was analyzed by X-ray,fluorescence spectrochemi-cal analysis(XRF),field emission scanning electron microscopy(FESEM),energy dispersive spectrometry(EDS)and X-ray diffraction(XRD).The results show that the kiln skin in the high temperature zone of the ferronickel rotary kiln is divided into 4 layers,and each layer has its own unique morphology characteristics.The main phase composi-tion is magnesium ferric silicate and MgSiO3,and the component proportion varies due to the influence of high tempe-rature,reducing atmosphere and liquid phase.The liquid phase particles containing Fe3O4,FeO and NiO are widely distributed in the silicate liquid phase.The tendency of crystallization of the contact layer between the kiln skin and the lining is weak,which creates the conditions for the silicate liquid phase to adhere to the lining.
