Wedge bending-roller straightening deformation method for circularly solidifying waste titanium chips

Abstract

The invention provides a wedge bending-roller straightening deformation method for circularly solidifying waste titanium chips. The method comprises the following steps: (1) recovering and pretreating Ti chips, namely, cleaning the titanium chips to remove oil stains and impurities; (2) drying and deairing the Ti chips, namely, drying and deairing the pre-treated Ti chips; (3) sleeving and sealing Ti chips, namely, filling the dried Ti chips obtained in step (2) into a copper barrel cavity, and then primarily compacting the chips through a manual press; (4) performing cold rolling on the sleeved Ti chips under room temperature, namely, performing cold rolling on the sleeved and sealed Ti chips obtained in step (3) among rollers so as to obtain a cold-rolled pure Ti board; (5) performing wedge bending-roller straightening deformation high-temperature solidifying processing; and (6) quenching, namely, quenching to cool the Ti material subjected to high-temperature solidifying processing in step (5) to reach the room temperature in a water cooling manner.

Description

technical field [0001] The invention belongs to the field of metal material processing, and relates to solid-phase recycling and reuse of waste metal resources, especially for titanium resources with high smelting costs, and develops a new technology for efficient and clean titanium chip remanufacturing. In particular, it relates to a wedge bending-roll straight deformation method for cyclic solidification of titanium waste chips. Background technique [0002] Titanium is a metal resource with high smelting costs. It has excellent biocompatibility, good corrosion resistance, and suitable mechanical properties. It is an important material for manufacturing medical devices, artificial joints, and large energy and chemical containers. However, in order to manufacture high-precision Ti structures, a large machining allowance needs to be designed, and a large amount of raw materials will be converted into waste chips. The traditional high-temperature melting and casting process ...
