Then insert the central shaft 5 into the center of the roll body 1, and make one end of the reinforcing rod 7 slide into the chute 19, then the hollow area inside the roll body 1 can be reinforced by the reinforcing component, increasing the anti-extrusion ability, thereby increasing the service life of this waterless furnace roll.
[0029] In some technical solutions, such as Figure 1 and Figure 4 As shown, a number of particle bumps 3 are equidistantly arranged on the outer wall of the roll body 1, and heat insulation cotton 18 is arranged on both sides inside the roll body 1. The particle bumps 3 and the roll body 1 are connected by casting, and the number of particle bumps 3 forms a particle pitted surface on the surface of the roll body 1.
