Definitions

  • the invention relates to a rotary apparatus for refining molten metal having a cylindrical rotor fixed to a hollow shaft formed by two parallel disks connected to radial partitions, and having a central cavity open at the bottom and top with a feed bore in the shank is connected, starting from the cavity channels, which are separated by intermediate walls and wider in the radial direction.
  • Molten non-ferrous metals such as aluminum and its alloys, must be refined prior to casting, i. from gases and non-metallic waste.
  • Aluminum is especially hydrogen and calcium.
  • the hydrogen solubility in an aluminum melt increases with temperature, while it is very low in the solid phase.
  • the gas and solid shots scattered in the melt may result in pores in the casting, thereby causing a deterioration of their mechanical properties.
  • the refining of the fused metal is usually carried out by means of a rotary device which whirls in the melt and supplies to the melt dry inert gas such as argon, nitrogen or their mixture together with reactive salt mixtures.
  • the gas passes through the hollow shaft into the rotor, which dissipates the gas in the form of fine bubbles in the melt at the bottom of the melting vessel.
  • the bubbles pass through the melt, the hydrogen diffuses into the bubbles, rises with them to surface and escapes into the atmosphere. At the same time, the bubbles bind solid shoots and take them to the surface, where they are collected as slag.
  • the rotor is formed by two parallel discs, between which there are radial channels separated by dividing walls.
  • the rotor has a central downwardly open chamber connected to a bore in the shaft and to the radial channels of the rotor.
  • the degassing after the EP 2017560 differs from the latter essentially in that the same recesses are made in the upper and in the lower disc of the rotor.
  • One of the versions of the in the US 6,589,313 described rotor differs from the rotor after the EP0332292 in that the rotor is provided on the upper side with radial ribs, but which have no influence on the movement of the melt under the rotor.
  • the rotor after the US 6,056,803 has an upper cone-shaped part and a lower cylindrical part, in which there is a central cavity. From this excavation go out radial, open at the bottom side channels. The gas is fed through small holes directly into the channels.
  • a rotor head for refining the molten metal having a central cavity into which gas is fed.
  • a rotary device for refining metal melts comprising a cylinder-shaped rotor fixed to a hollow shaft formed by two parallel discs connected to radial partitions, and one open at the bottom and connected at the top to a feed bore in the shaft Central cavity has, starting from the central cavity channels, which are separated by the intermediate walls and wider in the radial direction.
  • the rotor according to the invention is provided on the lower side with radial blades.
  • the blades are advantageously arcuate, oriented with their convex side in the direction of rotation.
  • joints are formed, which connect the respective channel with the lower side of the rotor.
  • the joints are advantageously guided along the convex flanks of the blade.
  • the circumference of the rotor is provided with longitudinal ribs which connect to the partitions.
  • the length of the longitudinal ribs corresponds to the height of the partitions.
  • the length of the longitudinal ribs may correspond to the height of the rotor, wherein the ribs pass into the blade at the lower end.
  • the partitions are provided with projections which protrude into the cavity.
  • the inventive device for refining of molten metal after Fig. 1 is formed by a cylindrical rotor 1 , which is screwed to a provided with a specific gas supply hole 2 shaft.
  • the rotor 1 is formed by two parallel disks 3, 4 , which are connected by radial partitions 5 .
  • the rotor 1 has a central cavity 6, which is open at the bottom and connected at the top to the bore in the shaft 2 . Between the discs 3, 4 are through the partitions 5 separate channels 7, which emanate from the cavity 6 and are wider in the radial direction.
  • radial arcuate blades 8 are mounted, which are directed with their convex side in the direction of rotation, that are bent in the direction of rotation. The direction of rotation is marked with an arrow.
  • the number of blades 8 corresponds to the number of partitions 5.
  • the blades 8 are below the partitions fifth
  • the partitions 5 are provided with projections 11 which protrude into the cavity 6 .
  • the cavity 6 has here, in comparison with the above, a slightly larger diameter.
  • the inert gas containing the dispersed reactive salts is injected through the bore of the stem 2 into the cavity 6 of the molten rotor 1 .
  • the rotor 1 operates similar to the rotor of a radial pump, ie it sucks the melt from below into the cavity 6, and as a result of the centrifugal force it hurls it into the environment.
  • the melt is mixed in the cavity 6 with the gas, it form fine bubbles, which are scattered together with the melt in the entire profile of the melting vessel. This effect is reinforced by the ribs 9 .
  • the radial vanes 8 on the lower side of the rotor 1 cause a swirling of the melt under the rotor 1, and lead to a toroidal vortex, in whose distal part the melt sinks and in the proximal part it rises.
  • the impurities accumulating on the bottom of the crucible are swirled to the level of the bubbles and then carried to the surface by them.
  • the protrusions 11 projecting into the cavity 6 mix the gas fed into the cavity 6 with the melt and thereby assist the generation of the bubbles.
  • the rotors according to the invention also have a better distribution of the speeds in the horizontal planes at the same rotational speed.
  • the following table shows the maximum melt velocities at the exit from the channels of the rotor with V1 max and 10 mm below the rotor with V2 max .
  • the rotor according to the variant of the invention Fig. 3 with a diameter of 190 mm was tested at a speed of 500 1 / min in a foundry when refining aluminum melt during piston casting.
  • the refining is carried out here in a conventional manner, first with nitrogen, then with chlorine, and finally reactive salt mixtures are added.
  • the calcium content in the melt is determined.
  • the refining is terminated when the calcium content has approached zero.
  • the calcium level dropped to 3 ppm after 3 minutes and the refining had to be continued for another 1.5 minutes.
  • the calcium content dropped below 1 ppm after 3 minutes.
  • the use of the rotor according to the invention in this foundry further showed that this rotor has a more favorable effect on the composition and consistency of the slag.
  • a slurry of slag containing up to 50 kg of aluminum per batch was formed.
  • Fine dusty slag was formed containing only 20 kg of aluminum per batch. This fact is due to a better mixing and purification of the slag in the whole volume of the melting vessel.
