Abstract

The invention relates to the technical field of wear-resistant metal materials and discloses a manufacturing technique for a duplex metal compound crusher hammerhead. The manufacturing technique for the duplex metal compound crusher hammerhead comprises the steps of smelting, wearing layer casting, hammer handle casting, hammerhead evanescent mode casting, pouring, cooling, heat treatment and the like. According to the manufacturing technique for the duplex metal compound crusher hammerhead, a wearing layer is welded at the front end of the hammerhead, the abrasive resistance of the crusher hammerhead is improved, the service life of the hammerhead is prolonged, and the requirements of impact resistance on the hammerhead by a crusher are met. The manufacturing technique for the duplex metal compound crusher hammerhead is simple, a hammer handle is closely connected with the hammerhead, the hammerhead is not prone to falling off when used, and the hammerhead is good in hardness, high in intensity and good in toughness.

Description

technical field [0001] The invention relates to the technical field of wear-resistant metal materials, in particular to a production process of a double-metal composite crusher hammer. Background technique [0002] Hammer crusher is a production equipment widely used in industrial sectors such as building materials, metallurgy, and chemical fertilizers, and the hammer head is a wearable part that consumes a lot. The working surface of the hammer head is in contact with the material, resulting in high stress wear. Since the crushed materials are generally hard objects such as rocks and metal ores, the wear of the parts is relatively serious. Through the analysis of the microscopic morphology of the hammer head surface, the wear process of the hammer head is the result of the combined action of deformation and erosion wear. This is due to the high-speed operation of the surface of the hammer head, and the inertia of the hammer head strikes and crushes the material. In the p...
