Abstract
The invention provides a husking wheel which comprises a hollow cylindrical substrate core with two open ends, wherein a hard alloy high-temperature-resistant and wear-resistant layer is arranged on the periphery of the substrate core; the middle part of the outer surface of the hard alloy high-temperature resistant wear-resistant layer is provided with an arc-shaped groove along the circumference. The invention adopts a cladding process, so that the new hard alloy material is combined with the substrate core material more firmly and cannot fall off. Meanwhile, the novel hard alloy material contains a large amount of Mo element, and when the peeling wheel works, Mo oxidation products can be formed by friction of a working surface, and the Mo oxidation products have a certain lubricating effect on a contact surface, so that the friction loss of the material is reduced.
