Erosion-resistant zirconium oxide slag line

The invention discloses an erosion-resistant zirconium oxide slag line. The erosion-resistant zirconium oxide slag line comprises a slag line body, wherein a first anti-erosion layer is arranged on the top of the slag line body; the first anti-erosion layer comprises a magnesium oxide layer; the top of the magnesium oxide layer is fixedly connected with a silicon nitride layer; the top of the silicon nitride layer is fixedly connected with a boron carbide layer; the top of the first anti-erosion layer is equipped with a second anti-erosion layer; and the second anti-erosion layer comprises analuminum oxide layer. According to the erosion-resistant zirconium oxide slag line disclosed by the invention, the first anti-erosion layer, the magnesium oxide layer, the silicon nitride layer, the boron carbide layer, the second anti-erosion layer, the aluminum oxide layer, a chromium oxide layer, the silicon carbide layer and a chromium oxide layer are matched for use, so that the problem thata slag line brick is relatively poor in erosion resistance as an existing slag line brick is corroded and oxidized in use is solved. The erosion-resistant zirconium oxide slag line has the advantage of a good erosion resistance effect, so that the service life of the slag line is prolonged, and practicability of the slag line is improved.
