As the essential material for high temperature industrial production and technological development such as metallurgy,refractory has an important influence on the safety and efficiency of production for high-quality steels.Slag corrosion is one of the main reasons causing the wear of refractories.The slag resistance of refractories can be enhanced by regulation and control of the composition and structure,while applying the external electromagnetic field can achieve the good performance.Electromagnetic field can not only change the thermo physical properties of slags,but also have a significant effect on the slag resistance of refractories.Suitable electric field can slow down the slag corrosion while the influence of conductivity of refractories is obvious;The magnetic field with millitesla level have a significant impact on the high temperature properties of the slags,and the alternating magnetic field can accelerate the slag corrosion of the refractories,while the static magnetic field has a promising potential to improve the slag resistance of the refractories.Furthermore,the interaction mechanism between refractories and slags under magnetic field needs to be clarified in order to develop the magnetic resistance against slag corrosion of refractories.
