Thermal spray atomization method of making alloy powder equipment(二)
Drying device, the main far-infrared heating furnace, vacuum drying furnace, baking powder plate, powder rake, spoon, funnel, car, flour bucket and so on.
Packaging equipment: The main screening machine, pounds, balers, blenders, bottled nitrogen, (for the easy oxidation of metal powder protection, usually placed in easily oxidized metal powder barrel, filled with nitrogen Sealed, so that in a certain period of time to prevent the barrel of metal oxidation.) Trolley and so on.
Testing equipment: a set of standard sieve, for the detection of powder particle size; magnification thirty times the microscope; metallographic microscope; hardness; balance; powder chemical composition of the detection is generally sent to the local Shangju Bureau detection, Allowed, the second is the authority, high credibility.
In aerosolization, the pressure of bottled nitrogen is limited, and atomization pressures of usually eight to ten atmospheres can be used. When using water atomization, commonly used atomization pressure has one hundred atmospheres to three hundred atmospheres. In order to produce more than 300 meshes, there is an atomization pressure of 500 atmospheres. Recently, in order to produce ultra-fine alloy powder with a fineness of more than one thousand mesh, some domestic manufacturers have built ultra-high pressure water atomization devices with atomization pressure of one thousand atmospheres.
