Abstract

The invention relates to a tapping tube for a metallurgical fusion pot. The aim of the invention is to provide a tapping tube which minimises possible downtime and enables essentially identical tapping durations during the use of the tapping tube. To this end, the tapping tube functionally divides into two parts, namely a first part embodied according to prior art, and a second part that can be connected to the first part in an easily exchangeable (replaceable) manner, thus forming a complete tapping tube. According to the invention, the section of the tapping tube relating to the flow is the outlet end. The cross-section of the outlet end determines the outflow quantity and thus the outflow duration (tapping duration) of the metal melt.

Claims (15)

1. A tapping tube (10) for a metallurgical melting vessel (12) with a through-flow channel D for a metal melt, which channel connects an inflow end E with an outflow end A, in which, starting from outflow end A, an associated cylindrical end section of the tapping tube (10) adjacent the through-flow channel D is designed as a separate, cylindrical part B, the first end of which part, comprising the outflow end A of the tapping tube (10) is designed to create a fixed but detachable seating for part B in a retaining mechanism (22; 34), and the second end of which has a front surface (24) facing towards inflow end E, which surface being tightly arranged against an axially adjacent section (26) of the tapping tube (10) when part B is in a retained position.
2. The tapping tube according to claim 1, wherein the cylindrical part B has an internal cross section corresponding to a target cross section of through-flow channel D.
3. The tapping tube according to claim 1, wherein the internal cross section of part B is constant over the entire height.
4. The tapping tube according to claim 1, wherein part B is fitted in an outer, cylindrical end section of the tapping tube (10).
5. The tapping tube according to claim 1, wherein part B has an external thread extending adjacent outflow end A.
6. The tapping tube according to claim 1, wherein part B has buffers (32) at its outer surface or at outflow end A for a compression means (34, 36), which biases component B towards inflow end E.
7. The tapping tube according to claim 1, in which the front surface (24) at the second end of part B has a surface contour (24r).
8. The tapping tube according to claim 7, in which the surface contour (24r) is made up of raised ridges extending concentrically with each other or in spiral formation.
9. The tapping tube according to claim 1, in which the frontal surface (24) at the second end of component B describes an annular section of an imaginary ball.
10. The tapping tube according to claim 1, having a seal (28) between the front surface (24) at the second end of part B and the axially adjacent section (26) of the tapping tube (10).
11. The tapping tube according to claim 10, in which the seal is made from a sealing compound.
12. The tapping tube according to claim 10, in which the seal is made of an annular sealing foil with a surface that is structured on one or both sides.
13. The tapping tube according to claim 1, in which the section (26) of the tapping tube (10) that is adjacent the frontal surface (24) on the second end of the component is flat in design.
14. The tapping tube according to claim 1, having a blocking element (40) that temporarily fills the internal cross section of part B.
15. The tapping tube according to claim 1, in which part B has a length that is equivalent to 1.5 to 3 times the smallest internal diameter of the tapping tube (10).
