More Information
Summary:The invention discloses a protective plate for a coal falling opening of a circulating fluidized bed boiler and a preparation device and method of the protective plate. The protective plate comprises a heat-resistant steel base plate and reinforcing filler, a plurality of linear groove arrays are sequentially formed in the upper surface of the heat-resistant steel base plate from left to right, and each linear groove array comprises a plurality of grooves which are sequentially arranged along a straight line. Each groove is cylindrical, the reinforcing filler is arranged in the grooves through laser cladding, the radius r of each groove is 3-6 mm, the depth of each groove is 3-4 mm, the reinforcing filler is 1-2 mm higher than an opening of each groove, and the depth of each groove is gradually reduced from left to right. The height difference between the top of the reinforcing filler and the opening of each groove is only 1-2 mm, so that although the reinforcing filler slightly higher than the opening of eac
