Its arrangement is more flexible, and the protection effect is better than that of anti-wear beam. However, the anti-wear metal plate must be connected to the fin of water-cooling wall by welding during installation. Since the anti-wear plate not only bears the scouring of material flow, but also bears high-temperature oxidation and high-temperature corrosion, it contains a large amount of alloy elements, which makes its weldability very poor. During the installation of anti-wear plate, it is difficult to weld, and problems such as cracking of weld and even falling off of anti-wear plate often occur.
