  • About author:Huang Ao is a professor of the State Key Laboratory of Refractories and Metallurgy, and School of Materials and Metallurgy at Wuhan University of Science and Technology. He earned his doctoral degree in materials science at Wuhan University of Science and Technology in 2010. After this he did post-doctoral research at the Chair of Ceramics at the University of Leoben. His research interests cover interaction between refractories and melts with or without external fields, mathematical and physical simulation of the application and wear of refractories especially for lightweight refractory materials. He won Hans Theis bacher-prize for outstanding research at Montanuniversität Leoben in Austria. He got excellent paper award in the youth academic annual meeting of the Chinese Society for Metals, and the first prize of Provincial Science and Technology Award for 4 times.


As the essential materials for high temperature industrial production and technological development such as metallurgy, refractories have 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 has 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 of slag corrosion of refractories.
