Environment-friendly dust-free smokeless metal additive production process

Abstract

The invention relates to the technical field of aluminum alloy additive production, in particular to an environment-friendly dust-free smokeless metal additive production process. According to the process, the floating phenomenon of metal powder in the pressing process can be reduced, and the pollution to the production operation environment can be reduced; and moreover, the black smoke generatedin the casting process can be reduced, and the pollution to the casting production environment can be reduced. The process comprises the following steps of (1), raw material screening; (2), raw material mixing; (3), release agent spraying; (4), preheating; (5), pressing; (6), demoulding; and (7), packaging and storing.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy additive production, in particular to an environment-friendly, dust-free and smoke-free metal additive production process. Background technique [0002] As we all know, with the continuous development of aluminum processing and aluminum alloy industry, the development of aluminum alloy is listed as a key development technology. During the smelting process of aluminum and aluminum alloy, it is necessary to add titanium, copper, manganese, iron and other metals to adjust the aluminum alloy The composition of the composition is generally adjusted by adding metal additives for aluminum alloys to aluminum and aluminum alloys during casting. Existing metal additives for aluminum alloys use a mixture of metal powder raw materials with a particle size of -100 mesh and flux to be pressed into a round cake through an assembly die of a hydraulic press, and the metal powder will generate certain dust f...

AI Technical Summary

Problems solved by technology

Existing metal additives for aluminum alloys use a mixture of metal powder raw materials with a particle size of -100 mesh and flux to be pressed into a round cake through an assembly die of a hydraulic press, and the metal powder will generate certain dust floating in the air during the process of pressing and flowing. During the process of metal additive pressing, in order to meet the normal production of the demoulding and pressing of the mold sleeve, a relatively large amount of release agent is generally added to the additive ingredients, generally adding 0.6%-0.8% hard Fatty acid, the user will produce a large amount of black smoke from the combustion of organic matter during melting and casting, polluting the casting production environment
