Definitions
- the aim of gas purging for example in a steel ladle, is in particular a quick temperature and concentration compensation of the steel bath and its cleaning.
- non-metallic inclusions should be conveyed faster into the slag floating on the molten bath with the help of the gas stream.
- the aforementioned DE 38 10 098 C1 also offers the possibility of guiding an alloy wire into the melt along a tubular passage channel in the gas purging stone.
- the alloy wire is supplied from the outside and runs through a gas distribution chamber, which is formed at the cold end of the gas purging plug and supplies the further purging channels with purging gas.
- At least one measuring device for determining physical and / or chemical data of the molten metal, which is adjacent to the hot side of the gas purging plug after the installation of the gas purging plug in the
- the gas distribution chamber can be divided into subchambers. Individual groups of channels can then be switched on or off. Different purge gases can also be supplied.
- the “measuring channel” should run in a straight line.
- “straight-line” is defined in such a way that the measuring head can detect at least 50% of the cross-sectional area of the channel on the hot side of the gas purging plug. In the ideal case, the value will be 100%.
- the gas distribution chamber 22 is delimited on the upper side by a lower end face 26 of the ceramic body 10.
- a metal jacket 24 extends on the U-side, which is shrunk onto the cold-side end 12 of the body 10 and projects downward beyond the end face 26.
- a bottom plate 28 closes the jacket 24 in parallel and at a distance from the end face 26. Two openings are provided in the base plate 28.
- a first opening 30 is used to connect a gas supply pipe 32, which is part of a gas supply device 34, which includes a gas reservoir (not shown).
- the measuring head 40 is designed such that it receives the electromagnetic waves emitted by a molten metal in the channel 16 and forwards them to an evaluation unit 44, which calculates the temperature of the molten metal based on the intensity of the received electromagnetic waves.
- the rinsing channel 18 has a smaller cross-sectional area than in the exemplary embodiment according to FIG. 1. For the rinsing channel 16, this only applies in relation to the section above the measuring head 40, so that the channel 16 is formed with a step 17 in the transition area.
- the upper section of the channel 16 is formed by a ceramic tube 60 which is embedded in the body 10.
- the measuring head 40 is sealed off from the interior of the gas distribution chamber 22 by an annular seal 23. Purge gas is only passed into the duct 16 behind the measuring head 40 (in FIG. 2: above the measuring head 40) via a further flushing channel 19, which has the function of a bypass.
