AI Technical Summary
Existing chute liners suffer from insufficient wear resistance and impact fracture due to large ore particle size and high throughput, resulting in short service life and affecting production continuity.
The cast-infiltrated composite chute liner consists of a chute liner body and a cast-infiltrated alloy layer. The cast-infiltrated alloy layer is composed of high-carbon ferrochrome powder and ferrovanadium powder, combined with PVB resin binder. The metallurgical bond is formed through lost foam casting and heat treatment processes, which improves wear resistance and toughness.
This improved the wear resistance and service life of the chute liner, reduced the frequency of downtime for replacement, and extended the service life of the equipment.
