Extending the service life of fused zirconium corundum bricks in glass electric melting furnaces
As we all know, the glass tank kiln melts horizontally, the material liquid level moves horizontally, and the erosion is serious at the three-phase interface except for the flow liquid hole, as shown in Figure 1. The glass electric melting furnace is vertical melting, most of which are cold top melting, the glass liquid surface is covered by a layer of raw material layer, and there are fewer three-phase interfaces. Because it is vertical melting, the erosion of pool wall brick is no longer concentrated in the three-phase interface, but the overall erosion, so the weak link of fused corundum brick is the breakthrough of erosion.
