Abstract Compared with the normal non-crusted slag,phenomenon of ladle slag encrustation in the production process of electrical steel was analyzed from three aspects of composition, phase and viscosity of the material. The results shown that with the decrease of temperature, a large a mount of high-melting phase such as MgO, MgO·Al₂O₃and 2CaO·SiO₂ and so on were precipitated from the slag, which not only acts as a "pinning" reinforcement in the slag, but also can lead to an increase in the viscosity of the slag, so it was very easy adhesion to agglomerate into a shell. In addition, relevant measures have been proposed to prevent ladle slag encrustation.

Key words： electrical steel ladle slag crust high melting point phase viscosity
