Embodiment Construction
[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0017] As shown in the figure, a Y-shaped wear-resistant spectacle plate includes a spectacle plate body 1 and a hard alloy wear-resistant layer on its working surface, and a cemented carbide block 2 is tailor-welded on the hard alloy wear-resistant layer. The matching gap between the hard alloy blocks 2 is a Y-shaped gap 3, and the Y-shaped gap 3 is filled with flux. The quantity of said cemented carbide block 2 is 4 pieces. The thickness of the hard alloy wear-resistant layer is 6mm. The welding method of the cemented carbide block 2 is brazing. The gap D between the Y-shaped slit 3 and the end of the feed hole is 1 mm. The included angle between the edge lines of the Y-shaped slit 3 is 30 degrees. The Y-shaped slit 3 is a parallel straight section with a length L of 2 mm near the feeding hole.
[0018] The gap between the cemented carbide blocks 2 for...
