Embodiment Construction
[0015] The present invention will be further described below in conjunction with the accompanying drawings.
[0016] As shown in Figure 1, choose cast steel or cast iron guide plate substrate 1, and use inorganic glue 3 to bond tungsten carbide block 2 on the worn position. Its main components are WC70%, Co30%, and the thickness of tungsten carbide block 2 is 4mm. The fit gap of the tungsten carbide block is 0.2mm, the machined groove at the wear position of the guide plate base is 4mm, the roughness of the joint between the guide plate base and the tungsten carbide block is below 3, and the base 1 is a cast steel, cast iron guide plate or a worn guide plate. When the area of tungsten carbide block is large, bolts can be used to increase the strength. For the repair of the guide plate of the rolling mill bonded with the tungsten carbide block, if the glue needs to be removed, the guide plate can be soaked in ammonia water, and the glue layer can be destroyed by knocking and ...
