Description
Summary:In order to improve the service life of the hammer head of the crusher, the high chromium cast iron-medium carbon low alloy steel double liquid composite hammer head is used to replace the single material high manganese steel hammer head; the production process uses lost foam casting instead of sand casting. This article mainly studies the production technology of composite hammers from the aspects of hammer material selection, model making, pouring system design, pouring process and heat treatment process, and uses a metallurgical microscope to observe the bonding interface, and uses a scanning electron microscope to observe both sides of the interface. For element diffusion, the universal testing machine tests the interface combination. The results show that the composite hammer has a firm bonding surface and good bonding quality.
