Metal powder flame spheroidizing equipment and process thereof

Abstract

The invention provides metal powder flame spheroidizing equipment and a process thereof. The metal powder flame spheroidizing equipment comprises a powder feeding system, a powder spheroidizing systemand a collecting system; the powder spheroidizing system is connected with the collecting system through a conveying pipeline; the powder feeding system comprises a quantitative feeder and a materialuniform distributor; the quantitative feeder is connected with the material uniform distributor through a powder feeding pipe; and the material uniform distributor is connected with the powder spheroidizing system through a branch pipeline. According to the technical scheme of the invention, the uniformity of powder particles after being spheroidized can be effectively improved, and meanwhile, the processing efficiency and quality of the powder are conveniently improved; in addition, the problem of low flame spheroidizing temperature is effectively solved, the powder can be sufficiently heated in a high-temperature area; and meanwhile, the spheroidized powder can be well cooled by adopting an airflow, and the processing temperature of a heat field is not influenced while cooling, so thatcontinuous production and batch processing of materials are facilitated, the production efficiency and the processing quality are effectively improved, and the overhaul cost and the energy loss are effectively reduced.

Description

technical field [0001] The invention relates to plasma metal powder processing equipment, in particular to metal powder flame spheroidization equipment and its processing technology. Background technique [0002] 3D printing is becoming more and more common. However, in the production process, the temperature of the molten metal is several thousand degrees when it is atomized by plasma. It needs to be cooled, and then the metal powder is collected. The metal powder particles are required to be uniform. The traditional spheroidizing equipment can only spheroidize powder with low melting point at low temperature. The original spheroidizing equipment has complex structure, difficult maintenance, heavy equipment, large floor area and high production cost. A large amount of grinding powder has irregular shapes, and a large number of customers need powder with good sphericity, so a spheroidizing equipment that can spheroidize heterogeneous powder is needed.

Problems solved by technology

[0002] 3D printing is becoming more and more common. However, in the production process, the temperature of the molten metal is several thousand degrees when it is atomized by plasma. It needs to be cooled, and then the metal powder is collected. The metal powder particles are required to be uniform. The traditional spheroidizing equipment can only spheroidize powder with low melting point at low temperature. The original spheroidizing equipment has complex structure, difficult maintenance, heavy equipment, large floor area and high production cost.

However, this equipment still has the following disadvantages: the powder feeding system cannot provide quantitative and uniform feeding, and at the same time, the flame spheroidization temperature is low, the heat preservation effect is poor, and the high temperature spheroidization temperature cannot be reached, which increases energy consumption and makes the processed balls Inhomogeneous granulation, unstable production, and easy damage to equipment
