Definitions
- the invention relates to a method for producing a metal powder consisting of surface-fissured, so-called squishy particles by applying a liquid medium to a pouring stream of a molten metal.
- Metal powders are predominantly produced by breaking a liquid melt into particles and then solidifying it.
- essentially gas or liquid jets are known as means for disintegrating the liquid metal into small droplets, which jets are allowed to act on a melt stream with high kinetic energy.
- gas-atomized metal powder with largely round, superficially essentially smooth particles is ideally suited for the production of dense bodies or materials, for example by hot isostatic pressing.
- a surface-fissured, so-called spattery powder grain is created by dividing the melt stream with liquids, especially with water.
- the so-called water-atomized metal powder usually has a lower bulk density after drying, the pouring properties also deteriorating due to the surface formation.
- a so-called green compact can be created, which is continuously porous due to the jagged surface structure of the grains.
- the green compact or pressing prior to sintering often has the desired stability, which promotes non-destructive manipulation.
- the spattery powder grain shape is advantageously suitable for producing objects from such water-atomized powders by sintering which have a high, but possibly inhomogeneous have distributed and coherent internal porosity.
- a particular area of application for objects or machine parts with high internal porosity are maintenance-free plain bearings in which the cavities containing the connections are filled with lubricant.
- the powder grains should have a lively surface structure with as many irregular, possibly sharp-edged projections and essentially the same and low grain weight.
- a molten metal is broken up with liquid or a so-called water atomization from metal to powder by applying water to an essentially vertical pouring jet directed sideways downwards (Metal Powder Production and Characterization, ASM Handbook, Volume 7, Powder Metal Technologies and Applications, pages 35 to 52).
- the high-pressure or high-speed water jet can have an annular V-shape or cone shape, an open V-shape, a closed V-shape, a pyramid shape or a special shape.
- the angle at which the water jet strikes the metal stream or the vertical speed component hits the metal stream is important for the formation of powder particles. As the angle of the water jet increases, the average particle size of the powder decreases.
- the aim of the invention is to overcome the disadvantages of the prior art and to provide a method of the type mentioned at the outset with which metal powder with low grain weights or a high proportion of small powder grains and improved sharp-edged or spattered parts is available within narrow limits Surface form can be produced, which powder provides more favorable processing properties and higher quality of the parts sintered therefrom.
- the liquid metal particles have a high kinetic energy when they come into contact with the high-speed current, which is at least partially formed with liquid medium, and are shot into it, so to speak, which also suppresses the "welled up water” phenomenon.
- the following step can a large angle of application of the liquid high-speed stream can be applied without the so-called "welled up-water” phenomenon occurring.
- these conditions bring about an effective disintegration of the liquid metal particles into small, largely equilibrium particles, and on the other hand an advantageous surface shape of the powder grains solidified from the particles.
- the method can be carried out particularly effectively, in particular if the metal is overheated by the pouring jet, if the pouring jet is deflected and its surface area is enlarged in the first step and / or the surface-enlarged pouring jet is deflected and comminuted and the liquid metal particles formed are accelerated in the second step with (a) streams (stream) formed at least partially with liquid medium.
- a deflection from the flow direction and an increase in the surface area of the pouring jet take place in the first process step with a gas stream, a comparatively less dissipation of thermal energy from the liquid metal is achieved or a reduction in the overheating is reduced, as a result of which a breakdown into liquid metal particles with less Viscosity can be promoted.
- the surface-enlarged pouring jet is deflected and broken up and the liquid metal particles formed thereby are accelerated in a gas flow in the second process step.
- This measure brings about a lower lowering of the temperature in the region of the metal particles near the surface, in particular when accelerating the same, and intensifies in the third process step, when it hits and / or is immersed in the high-speed stream formed with liquid medium, that the surface of the powder grains becomes fissured or becomes brittle. It is believed that this beneficial effect is brought about by an improved surface contact between the metal with a high degree of liquid or with increased overheating and the liquid medium.
- liquid metal particle stream is acted upon and divided into at least partially liquid medium by a high-speed flat stream.
- the invention further aims at an embodiment of the above Process by which the quality of the spattery powder from some metals and alloys is improved.
- This goal is achieved in that a deflection of the pouring jet in its direction of flow and an increase in its surface area in the first process step and / or a deflection of the surface-enlarged pouring jet and its comminution, and an acceleration of the liquid metal particles formed in the second process step with (a) from heated gas ( en) formed current (currents) take place.
- the gas stream for the first and / or for the second process step is heated to a temperature of above room temperature, preferably of above 200 ° C., in particular of above 400 ° C., optionally by means of a heat exchanger.
- a precise setting of the elevated temperature of the gas flow can be done, for example, with a heating coil in a flow channel. In this way, the surface of small metal particles in particular Heat dissipation and a thickening of the near-surface zone are reduced or delayed.
- a gas or gas mixture with a low cooling effect on the surface of the pouring jet or the liquid metal particles is used for the first and / or for the second method step.
- the advantages achieved here are essentially due to the fact that the gas stream (s) for pretreatment or preparation of the pouring stream for fine division thereof are created in a particularly simple and inexpensive manner by means of the high-speed stream.
- heating of the treatment gas stream can be achieved on the one hand and, on the other hand, a resulting increase in volume can result in a favorable increase in the flow intensity.
- the combustion can also reduce the oxygen content in the treatment stream.
- the gas stream is heated and shaped in a means containing a burner, in particular high-speed burner.
- a burner in particular high-speed burner.
- the pouring jet emerging from the distributor and / or the surface-enlarged pouring jet can be acted upon with hot gas in the second process step and processed in such a way that the prerequisites for dividing it into desired high-quality metal powder can be achieved in the third process step.
- a device 3 which is advantageously designed as a flat jet nozzle device, acts in a first method step on the vertical pouring jet 2 at an acute angle ⁇ with a deflection medium 31, e.g. Water, water-gas mixture or gas, the pouring stream 2 flowing in the area 32 such that it is spread to enlarge the surface.
- a deflection medium 31 e.g. Water, water-gas mixture or gas
- a medium jet 41 advantageously formed with a wide shape and having an acute angle? incident flow.
- the widened pouring jet 21 is deflected again and divided into liquid metal particles 22.
- the liquid metal particles 22 become, as shown by the symbol V, by means of the medium jet 41 , accelerated.
- the accelerated liquid metal particles 22 are subsequently introduced or enclosed in the region 52 in a flat high-speed stream 51, which is directed at an angle für to the trajectory of the metal particles 22.
- the media jets 31 and 41 of the first and second process steps can also be formed advantageously with gas, preferably nitrogen, with an application of gas in the preparation of the metal stream for powder particle size, a lower superficial dissipation of overheating heat from the metal particles and an increased Can produce crispness of the grain surface of the powder with increased economy.
- gas preferably nitrogen
- FIG. 1a The embodiment of the invention is explained on the basis of a schematic illustration in FIG. 1a.
- a metal casting stream 2 which may be only slightly overheated, emerges from a metallurgical vessel through a nozzle block 11.
- a gas stream 6 enclosing it can be provided, which is brought to a temperature above room temperature.
- a means preferably designed as a flat jet device 3, for acting on and deflecting the pouring jet 2 generates a hot gas stream 31, for example at a temperature of over 600 ° C., which softens the pouring jet 2 without increasing the cooling effect.
- Another charging system 4 can also create a warm or hot gas flow 41, which, if necessary, also divides the surface-enlarged pouring jet 21 without disadvantageous cooling and accelerates the liquid metal particles.
- the loading systems 3 and 4 can also be at least partially designed as a burner device.
