Ultrasonic homogeneous mixing-proportioning device of multi-element metal powder

Abstract

The invention discloses an ultrasonic homogeneous mixing-proportioning device of multi-element metal powder. The mixing-proportioning device is composed of operating function components such as a mixing tank, a plate-type ultrasonic transducer, a vacuum air pump, a metal powder spraying feeder, a mixing disperser, a hydrogen injecting pump, an automatic control device. According to the mixing-proportioning device, the advanced power ultrasonic dispersion technology and the traditional mechanical atomization spraying stirring-mixing technology are combined. The mixing-proportioning device has a plurality of operating functions such as atomizing, spraying, vibrating, refining, dispersing, homogenizing, stirring and mixing. A plurality of elementary substance metal powder can be mixed and proportioned to be the multi-element metal alloy powder in one-time mode, and the multi-element metal alloy powder is accurate in component control, homogeneous and sufficient in dispersion, even in constituent element distributing, standard in particle size, and moderate in particle looseness. The mixing-proportioning device has the advantages of being advanced in technology, complete in functions, easy to operate, reliable in performance and the like. The mixing-proportioning device can be widely applied to powder metallurgy industry, and carries out dispersion and homogenous stirring and mixing on the various elementary substance metal powder.

Description

technical field [0001] The invention relates to a powder metallurgy equipment, in particular to a multi-element metal powder ultrasonic homogeneous mixer for preparing multi-element molybdenum-based alloy powder. Background technique [0002] Metal molybdenum is a rare and precious metal with high melting point, high strength and hardness under high temperature conditions, excellent electrical and thermal conductivity and good stability, etc. It has a wide range of applications and is widely used in many countries. Included in strategic resource management. However, metal molybdenum also has material defects such as low recrystallization temperature, poor mechanical and physical properties such as tensile strength, yield, and elongation, and difficulty in forming materials. With the development and progress of the level of science and technology, the research and test methods are also constantly improved. In the scientific production practice of powder metallurgy, people ha...

Problems solved by technology

However, since molybdenum-based alloy powder is different from metal powders such as iron, copper, aluminum, cobalt, nickel, and titanium commonly used in the field of powder metallurgy technology, not only the powder particle size of all ingredients is required to be finer, generally no more than 4 μm , and the pure molybdenum powder itself has the characteristics of large agglomeration bonding energy and poor fluidity, and most of the molybdenum-based alloy powders choose to use the compounding technology of multi-element metal powder mixing, using the existing Metal powder stirring and mixing mechanical equipment for solid / solid dispersion homogeneous mixing and mixing operations can meet the technical requirements of multi-component molybdenum-based alloy powders for mixing quality, and the prepared molybdenum-based multi-component alloy materials must also have uniformity and stability Poor material performance defects
