A process for making powder by using stainless steel scraps and scraps

Abstract

The invention provides a process for making powder through a stainless steel waste corner sheet metal. The powder is prepared by using an atomization method. The process comprises the following stepsthat S1, raw materials are sorted and graded; S2, cleaning and dewatering are conducted; S3, the technology ratio is formulated, smelting is conducted, and ingredients are added; S4, atomization for powder making is conducted; S5, dewatering and drying are conducted; and S6, screening and detection are conducted. The process has the beneficial effects that stainless steel edge corner waste materials are recycled, waste of the materials is reduced, the using ratio of stainless steel edge corner waste materials is increased, the metal powder is prepared by using the stainless steel waste cornersheet metal, so that the processing cost is low, and the raw materials are sufficient; and the metal powder is prepared by using the atomization method, so that the production efficiency is high, mostmetal and metal alloy powder thereof can be prepared, the metal powder quality is controllable, and using requirements of 3D printing and additive manufacturing are met.

Description

technical field [0001] The invention belongs to the technical field of metal powder preparation, and in particular relates to a process for making powder by using waste stainless steel sheet materials. Background technique [0002] For manufacturers of complete sets of stainless steel equipment, a large amount of stainless steel scraps will be produced every year in the process of producing equipment, resulting in a large amount of waste of materials. With the widespread application of 3D printing technology and additive manufacturing, metal powder, as one of the most important printing materials, has continuously expanded its application fields and the market demand has increased dramatically. At present, metal powder, the most important material for 3D printing and additive manufacturing, is mainly imported. Only by rapid localization can we completely get rid of the constraints of foreign companies. And 3D printing materials are the most important part of the 3D printing...

AI Technical Summary

Problems solved by technology

However, the realization of this method is to use double-layer water atomization nozzles for two atomizations, which requires modification of the equipment, which increases labor costs and production costs, and the quality of the prepared metal powder is not good enough to meet the requirements of 3D printing.
