Abstract
The present invention pertains to a gas purging plug for metallurgical vessels with a gas connection pipe at the gas inlet-side, lower end.
Claims11
Gas purging plug of a refractory matrix material for metallurgical vessels, the plug comprising
- a bottom portion,
- an upper end face,
- a circumferential wall extending between said bottom portion and said upper end face, and
- a gas connection pipe, having an upper end portion and a lower end portion, wherein
- the gas connection pipe extends from below said bottom portion of the gas purging plug in a longitudinal direction of the plug and the gas connection pipe has an upper end portion inserted into the plug and is connected to a gas permeable section within said refractory matrix material, which section runs up to the upper end face of the gas purging plug, the upper end portion of the gas connection pipe being completely surrounded by the refractory matrix material inside and out, and being gas permeable throughout the upper end portion, the gas connection pipe including at the lower end portion means for making a gas-tight connection to a gas distribution chamber or a gas feed line at the lower-end portion thereof, outside the refractory matrix material of the plug.
Gas purging plug of a refractory matrix material, for metallurgical vessels including a lower bottom, and upper end face and a circumferential wall between said bottom and said end face, with a gas connection pipe which has an upper end and which projects from below said bottom of the gas purging plug and extends in the direction of said end face and the upper end of said gas connection pipe being connected to a gas permeable section within said refractory matrix material which runs up to the end face of the gas purging plug, wherein the upper end of said gas connection pipe is located completely within the gas permeable section of said refractory matrix material and including means for a gas-tight connection to a gas distribution chamber or a gas feed line at a lower end of the gas connection pipe outside the refractory matrix material of the gas purging plug.
