coaching approach Of stainless steel Powder For 3D Printing

After the metal three-D printer is on fire, the metal 3D printing powder material can also be on the hearth, and the three-D printing steel powder marketplace will maintain a high growth trend. At gift, the domestic and overseas 3-D printing metal powder production method-the the latest development of aerosolization, Luoyang Tongrun analyzed the status of 3D printing metal powder guidance technology and put forward some reviews.

The 3-D printing era is a brand new type of printing generation. Its super benefits are that it could immediately generate any shape parts from computer graphics facts without machining or any molds, thereby substantially shortening the product development cycle, increasing productivity, and lowering production. 3-d revealed steel powder is the critical raw material for 3D Printing of steel elements, and its training method has attracted an awful lot of interest. Because of the essential part of the three-D printing industry chain of steel components, 3-D printed steel powder is also the maximum good sized cost.

The preparation technique of  Stainless Steel Powder For 3D Printing

At present, the powder preparation approach may be particularly divided into the discount technique, electrolytic method, carbonyl decomposition approach, grinding method, atomization method, and so forth, according to the coaching method.

Amongst them, it's miles greater not unusual to use powder produced by reduction, electrolysis, and atomization as raw substances inside the powder metallurgy industry. But, the electrolytic approach and reduction approaches are restricted to the manufacturing of elemental steel powder, and these methods do no longer practice to alloy powder. The atomization technique can produce alloy powder. At the identical time, the present-day atomization process can manipulate the form of the dirt.metal 3D printing powder

The continuously growing atomization hollow space structure has dramatically advanced the atomization efficiency, which makes the atomization technique gradually develop into the main powder — manufacturing technique. The atomization technique meets the man or woman necessities of 3D printing consumable metal powder. The atomization approach refers to a system of pulverizing a molten metallic into debris having a size of much less than about 150 μm by way of a mechanical technique.

In step with the technique of crushing the molten metal, it could be divided into atomization strategies together with two-circulate atomization technique, centrifugal atomization, ultrasonic atomization, vacuum atomization, and the like. Those atomization techniques have their characteristics and have been efficaciously carried out to business manufacturing. Among them, the water vapor atomization method has the blessings of the simple production system and era, low power intake, big batches, and so on.. It has come to be the number one industrialized production approach of metallic powder.

In the manufacturing of atomized powder, the water atomization technique is one of the reasonably-priced manufacturing methods. Due to the fact, the atomizing medium water is not simplest reasonably-priced and clean to achieve，, however additionally extremely good. At gift, the home water atomization technique is particularly used to supply metal powder, carcass powder for diamond gear, pre-alloy powder for oil-containing bearings, powder for tough surface technology, and iron-based totally and nickel-based totally magnetic powder. Because the capability of the particular heat of water is an awful lot larger than that of gas, at some stage in the atomization manner, the damaged metallic droplets end up irregular because of solidification too rapid, which affects the sphericity of the powder.metal 3D printing powder

Different metals or alloys with high hobby will react with water. At the same time, because of the touch with water all through the atomization manner, the oxygen content of the powder could be accelerated. These issues restrict the software of water atomization within the training of metal powders with high sphericity and occasional oxygen content. But, Luoyang Tongrun has invented a way for preparing spherical metal powder via water atomization, which makes use of a secondary bloodless water atomization nozzle beneath the water atomization nozzle to carry out secondary atomization. The sphericity of the powder acquired by means of the invention isn't simplest close to the effect of aerosolization, however, additionally, the particle length of the powder is greater stunning than that of unmarried water atomization.

Aerosolization

The fuel atomization is one of the number one techniques for generating metallic and alloy powders. The fundamental precept of gasoline atomization is the manner of breaking a liquid steel flow into small droplets, the usage of a high-velocity gas movement, and solidifying it into a powder. Due to the advantages of excessive purity, low oxygen content material, controllable powder particle length, low manufacturing value, and excessive sphericity, the powder organized has to turn out to be the main development course of excessive-overall performance and precise alloy powder training technology. But, the fuel atomization method also has shortcomings. The energy of the excessive-pressure gas circulation is far much less than the energy of the excessive-strain water movement. Consequently, the atomization efficiency of the steel soften is lower than that of the water atomization, which makes the atomization efficiency of the gas atomization powder smaller. Consequently, the manufacturing cost of the atomized powder is increased.
