AI Technical Summary

Technical Problem

Existing methods for manufacturing copper alloy crystallizing wheels have long processes, result in significant waste of raw materials, and produce inconsistent properties between the core and the surface, failing to meet the performance requirements of the core when in contact with high-temperature liquids.

Method used

The manufacturing method employs vacuum centrifugal casting and near-net-shape forming, including vacuum centrifugal casting of a crystallizing wheel ring billet, followed by machining, hot ring rolling, solution heat treatment, cold ring rolling, and aging heat treatment. This reduces the amount of machining and ensures the consistency of properties between the core and the surface layer.

Benefits of technology

This improved the yield and production efficiency of copper alloy crystallizing wheels, reduced production costs, ensured that the core structure was fine and consistent with the surface properties, and met the requirements for high-temperature liquid contact.
