AI Technical Summary

Technical Problem

Existing cold isostatic pressing technology has problems such as uneven powder loading, easy tearing of the casing and failure of the seal when processing ultrafine beryllium powder, which makes it impossible to prepare beryllium powder billets that meet the smelting requirements.

Method used

A composite end plug, consisting of an end plug body made of elastic material and a rigid core embedded therein, combined with a silicone sheath and a vibration platform, is used to prepare a high-density, defect-free beryllium powder blank through vacuuming and cold isostatic pressing.

Benefits of technology

It has achieved the preparation of high-density, defect-free beryllium powder blanks, solved the problems of uneven powder loading and shell tearing, improved material utilization, and reduced material waste.

Abstract

This invention proposes a molding device and a billet consolidation method for ultrafine beryllium powder, belonging to the field of beryllium powder billet consolidation technology. This invention employs composite silicone end plugs and cold isostatic pressing (COP) technology to prepare beryllium billets suitable for beryllium copper master alloys. It overcomes the technical problems of uneven powder loading, easy tearing of the casing, and sealing failure in existing COP technology when processing ultrafine beryllium powder. It provides a dedicated molding device and consolidation method capable of stably preparing high-density, defect-free ultrafine beryllium powder billets.
