Definitions
- the invention relates to a control and closure device for a metallurgical Vessel in which a rotor is arranged in a stator arranged in a vessel wall is rotatably supported, the stator and the rotor by rotating to cover have bringable flow openings and in the rotor a flow channel for Melt exists.
- melt in the area of this facility is not provided.
- the melt can have a temperature that is too low for undisturbed operation accept.
- the melt can freeze between sealing surfaces exist in the vicinity of the flow openings.
- DE 44 05 082 A1 describes an electromagnetic flow control device (EMC) with a nozzle in combination with an on / off valve, namely one Slide closure. Since the nozzle is made of electrically non-conductive material, couples the melt in it, but the nozzle itself to the electromagnetic one Field of the coil does not appear. The electromagnetic field should be in the slide lock for melting, couple to the melt which may have solidified there. There the slide is far outside the field of the coil, this is hardly, at best to be reached very delayed.
- EMC electromagnetic flow control device
- the coupling of the melt for the purpose of flow regulation is always included a temperature increase in the melt. A throttling of the However, the melt flow is not independent of the heating of the Melt possible.
- the object of the invention is a control and closure device of the beginning to propose the type mentioned, in which the throttling or regulating and Sealing a melt flow from a vessel with a heating option the melt is integrated.
- the heating should preferably be independent of the Control or closure function take place.
- the above object is the control and closure device type mentioned in that the rotor is surrounded by an inductor is at the field of the melt in the flow channel or the rotor can be coupled electromagnetically.
- the melt flow can be throttled by turning the rotor and interruptible and the melt can be heated so that it does not freeze or after a possible freeze can be melted or reheated if necessary.
- the melt heated by heat transfer from the rotor If the rotor couples to the electromagnetic field, then the melt heated by heat transfer from the rotor.
- the throttling and closing takes place independently of the heating by turning the rotor.
- melt flow can also be controlled by turning the rotor.
- a stator (1) made of refractory, ceramic material is in a vessel bottom (2) of a metallurgical vessel.
- the stator (1) has at least one side a flow opening (3) which opens into the interior of the vessel.
- a hollow cylindrical rotor (4) rotatable about a vertical axis (A).
- the rotor (4) has at least one corresponding to the flow opening (3)
- Flow opening (5) in the existing in the rotor (4), coaxial Flow channel (6) opens.
- the rotor (4) is enclosed by an inductor (11) which is cooled by a electromagnetic coil is formed.
- the Inductor (11) built into the vessel bottom (2) which is a special one for this Perforated stone can have.
- the stator (1) consists of both embodiments an electrically non-conductive, refractory, ceramic material.
- the rotor (4) is made of an electric conductive, refractory, ceramic material, such as a resin-bound, high alumina material.
- the rotor (4) not, however, or only insignificantly, the one flowing through the flow channel (6) Melt, thereby coupling to the electromagnetic field of the inductor (11).
- the mode of operation of the exemplary embodiment according to FIG. 1 is as follows:
- the rotor (4) is in itself for throttling and shutting off the melt flow rotated in a known manner around the axis (A). Regardless, can on the Melt temperature are affected.
- the inductor (11) switched on, whereby the rotor (4) is heated.
- the heat of the rotor (4) is transferred to the melt in the by heat conduction and / or heat radiation Flow channel (6) and in the flow opening (5).
- the melt temperature leaves thereby increasing in a desired manner, which among other things also it is avoided that melt freezes between the sealing surfaces (7). Is in the Closed position of the rotor (4) approximately melt between the sealing surfaces (7) solidifies, then it can be melted by switching on the inductor (11).
- the rotor (4) is in contrast to Embodiment according to Figure 1 from an electrically non-conductive, refractory, ceramic material, such as zirconium oxide.
- the rotor (4) does not couple to it electromagnetic field of the inductor (11).
- the mode of operation of the exemplary embodiment according to FIG. 2 is as follows:
- the melt flow can be throttled and shut off by turning the rotor (4).
- the inductor (11) If the inductor (11) is switched on, its electromagnetic field acts directly on the melt in the flow channel (6) and in the flow openings (5, 3). This on the one hand has a narrowing of the melt flow cross section and thus Throttling the melt flow and on the other hand heating the Melt.
- the throttling effect is due to the displacement body (12) reinforced.
- the regulation of the melt flow can be here through the electromagnetic field of the inductor (11) alone and in addition, if necessary Turning the rotor (4) can be reached.
- the displacement body (12) is for this not absolutely necessary.
- Heating the melt ensures that it does not freeze can.
