Description

The invention relates to powder metallurgy, in particular to devices for floor 74c-i-l steam-goats, melt melts and can be used for the manufacture of powder products by the accelerating casting method and powder coating. The purpose of the invention is to improve the safety of work and the expansion of technological capabilities. On . shows a diagram of the device .., a section along the axis; Fig 2, a crucible with radial taps during spraying; FIG. 3 is the same at the time of the end of the work; FIG. 4 is one of the embodiment of the device; On . 5 is a diagram of the mechanism of rotation: The device contains crucible 1 with melt; rotated from drive 2, headers 3 and 4, and form 5, provided with axial displacement drive 6., ma per, ifd-tgl i i holes are made for melt flow through, with cavities, radial h1e1x outlet, 7, installation sharggi .rmo, on the crucible: and equipped with an 8-turn and PLANE mechanism, G-rpendyknnositally on the tipg axis, while the radial 7 has a replaceable mc) with nozzles 9, and the bottom, lays down-: receiving hopper 10. V one of the var1; antov device is equipped with a form 3 with the possibility of scrapping around its axis with the help an additional actuator 11 and gear 125 a. The rotation mechanism 8 is made in the form of a spring 1.3, one end of which is fixed on the crucible,, j at the other end are loaded 14 which, under the action of centrifugal forces, can move along the canal, pu from the outside of the radial taps / ,,, The device works as follows-; way-. A material is placed in crucible 1, which is heated to the melting temperature with the help of 50 heater 3. At the same time, heaters 4 heat radial taps, 7, after which NK press drive 2 turns. When this is between, and; more than 30 ° “In this position, the ball valves are closed-gy and mat (rial from crucibles 1 not With an increase in the number of revolutions of rotation —i; l 1 chg-ol nak of the pit-1c, 1b, nd un The valve 972 is opened and the melt flows out through the feeder 7, conical nozzles 9, which allow you to adjust the particle size distribution of the resulting powder, the relationship between the flow rates of the melt from the conical and cylindrical nozzles being determined by the formula radius of the cylindrical nozzle; - the maximum radius of the conical nozzle; Gd minimum p the cone of the cone nasa.tski falls out to the cool, a: to, given form, 5, is cooled and in the form of a tape or powder falls into 10, while the angle between the axes of the radial taps 7 and the crucible, g; must be no more 120 ° as otherwise, ball valves shut off the melt supply channel to the 7t bends. This angle is controlled by tensioning the spring of the turning mechanism 9 or by weights 14. Besides, the device can be used for powder coating. In this case the crucible and the shape, made with the possibility of relative axial displacement and oschi drive. Powder is poured into crucible 1 or the material is heated to the melting temperature, and mold 5 is heated to 600-900 ° C. The actuator 2 turns on. When the crucible reaches a speed of i000-1300 rpm, k, papan opens and the powder is applied to the inner the surface of the mold, 5 ,, while the crucible 1 is moved along its ICE; which allows for an increase in the deposition rate of the coating. To obtain a more uniform coating layer, the form 5 can be made rotatable around its axis using an additional drive II and gear 12. When using the proposed object, the work safety is higher than the known one, since the heating of the meltile melts: m-gig, ras n 1p scope; as the proposed device can

It was used not only to obtain a material composition, as radio powder, but also for powder coatings are provided with replaceable conical coatings, the process is simplified with real nozzles, and the volume and grain size of the mechanization is increased.
