Detailed Description
A replaceable stud lining board, and figure 1-1 is a structural schematic diagram of the replaceable stud lining board in the utility model. Fig. 1-2 are schematic front views of replaceable stud backing plates of the present invention. The replaceable stud liner plate comprises a liner plate body 1, wherein bolt holes 2 are formed in the liner plate body, and the liner plate body is a whole formed by fusion of hard alloy studs 3 and metal. A notch is formed in the position, close to the spherical crown, of the end part of the hard alloy stud; a group of hard alloy studs with notches are arranged on the reinforcing surface of the lining plate body.
Fig. 3 is a schematic view of the structure of the middle stud of the present invention. The spherical crown of the hard alloy stud is arc-shaped, and the body of the hard alloy stud is cylindrical or regular hexagonal. The body corners of the hard alloy stud are in chamfer transition. And the bottom of the notch of the hard alloy stud is provided with an arc. A group of hard alloy studs with notches are uniformly distributed along the axial direction and the radial direction of the lining plate body. The specification of the hard alloy stud is 10 to 25 in phi and 10 to 50 in height.
