Definitions
- the invention relates to a device for introducing of a particularly gaseous treatment medium in one container filled with liquid metal, consisting of a metallic inner tube with a metal reinforcement for securing one penetrated by at least one outlet channel, fireproof casing.
- Such a device also referred to as a diving lance is known from EP-PS 0 261 365.
- treatment media such as gases, in particular inert gases and / or carrier gases with solids, for example slag-forming substances and carbon, in the liquid metal initiated.
- the Reinforced metal inner tube made of at least one helically wound ribbed band, which has a rectangular cross-section and upright to the longitudinal axis of the inner tube is arranged.
- the invention is therefore based on the object Device for introducing an especially gaseous treatment medium into a container filled with liquid metal create, in which the notch effect is significantly reduced and thus the service life is increased.
- the connection between the reinforcement and the refractory casing is to be improved so that a greater heat transfer from the reinforcement to the refractory Sheathing is achieved.
- the reinforcement consists of at least two corrugated and outside bars attached to each other offset on the inner tube which is at least a rounded outer cross section exhibit.
- the notch effect, that apply the reinforcement to the refractory casing can, significantly reduced, leading to an increase in tool life contributes to the device. Due to the inevitably larger Cross-section of the reinforcement is the heat transfer from the reinforcement improved on the refractory casing. But this carries also to increase the bending stiffness and reduce it the risk of torsion of the device.
- the lower area is one Device, also referred to as a diving lance, shown those for introducing a particularly gaseous treatment medium in a container filled with liquid metal.
- This device initially consists of a metallic tube, hereinafter referred to as the inner tube 1, with a relatively large Cross section, which in its lower or immersion area is closed by a plate 2.
- a plate 2 In this plate 2 is a Outlet pipe 3 used.
- the lower area of the inner tube 1 is of a fire-resistant casing 4 made of ceramic material enclosed in which there is an outlet duct 3a. To secure this casing 4 on the inner tube 1, the same is the same provided with a metallic reinforcement 5.
- the reinforcement 5 is in the illustrated embodiment from two rods 6 with a circular cross section, which as Helix shaped and attached to the inner tube 1. In the Drawing, however, only one rod 6 is shown. In advantageous The rods 6 are even over the circumference of the inner tube 1 distributed. Due to the helical design the rods 6 are the same only in individual places firmly connected to the inner tube 1. This means that the refractory Sheathing 4 made of ceramic material, the rods 6 partially fully encloses what a good connection of the casing 4 with the reinforcement 5 and thus with the inner tube 1 brings itself. Due to the circular cross section of the rods 6 Reinforcement 5 does not have any notch effect on the sheathing 4 exercised, which increases the life of the device or diving lance increased.
- the distance between the individual coils or turns the rods 6 of the reinforcement 5 is dependent on the diameter of the inner tube 1 about 50 to 200 mm.
- the diameter of the Bars 6 of the reinforcement 5 can be between 3 and 20 mm, wherein the outer diameter of the coils is about 15 to 40 mm.
- the Reinforcement 5 formed from at least two corrugated bars 6 is arranged entangled on the inner tube 1.
- the entanglement extends through an angle of approximately in the drawing 45 °; however, this entanglement can also be larger, for example Be 360 ° and more.
- the rods are 6 the reinforcement 5 is not crossed, but run exactly parallel to the axis of the inner tube 1.
- the rods 6, which form the reinforcement 5, than in one Form corrugated level can then either entangled according to Figure 1 or accordingly of Figure 2 extending axially to the axis of the inner tube 1 on the Inner tube 1 may be attached. The waves of the rods 6 then take off a radial position to the inner tube 1.
