High-temperature reduction deoxidation process of copper powder raw material

Abstract

The invention discloses a high-temperature reduction deoxidation process of a copper powder raw material. Copper powder is placed in a high-temperature reaction furnace, and then the temperature of the high-temperature reaction furnace is controlled to range from 200 DEG C to 400 DEG C; and hydrogen is injected into the high-temperature reaction furnace to react with the copper powder, and oxygen in the copper powder can be replaced. Through the arrangement of an inclined plate, an air cylinder, a mounting plate, a placement groove, a T-shaped groove, a connecting block, a storage groove, a positioning device, an extrusion hole and an extrusion block, the T-shaped block and the positioning groove are matched for use, the air cylinder is pushed to drive the T-shaped block to be inserted into the T-shaped groove and drive the extrusion block to be inserted into the extrusion hole, and then the push rod is pulled down to drive the pressing block to return to the original position; springs elastically deform to drive a movable plate to return to the original position, the movable plate moves the positioning plate to be inserted into the positioning groove, the installation of the air cylinder is completed, and the high-temperature reduction deoxidation process for the copper powder raw materials has the advantage of preventing the discharging plate from being blocked and is worthy of popularization.

Description

technical field [0001] The invention belongs to the technical field of copper powder high-temperature reduction deoxidation, and in particular relates to a high-temperature reduction deoxidation process of copper powder raw materials. Background technique [0002] After the copper powder and hydrogen are mixed, the oxygen in it can be removed through high-temperature reaction and become oxygen-free copper. The copper powder after removing harmful oxygen elements will greatly increase the strength of the metal, and will also increase the corrosion resistance and load-bearing of copper. In summary, after the copper powder is broken into pieces after processing, it will accumulate on the discharge plate because of its excessive weight. If there is no staff to take care of the discharge plate for a period of time, the copper powder block will be blocked. , Once the accumulation height is too high, it will fall to the ground, and the post-processing of the dust-contaminated coppe...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the problems existing in the prior art, the present invention provides a high-temperature reduction deoxidation process for copper powder raw materials, which has the advantage of preventing the blockage of the discharge plate, and solves the problem that the copper powder after the existing processing is broken into pieces due to excessive The weight will accumulate on the discharge board. If there is no staff to take care of the discharge board for a period of time, the copper powder block will be blocked. Once the accumulation height is too high, it will fall to the ground. The post-processing of the dust-contaminated copper powder block will be more difficult troublesome question
