摘要： A gas purging plug for blowing gas into a metallurgical vessel, having the form of an elongated body made of a first refractory material, contains a final visual wear indicator in the form of an elongated core extending from an inlet end to a distance, along a central longitudinal axis, less than the length of the elongated body. The final visual wear indicator is made of a second refractory material that differs in visual appearance from the first refractory material between 800 and 1500 degrees C. The plug also contains an intermediate visual wear indicator extending from the inlet end to a point between the end of the final visual wear indicator and the opposite end of the elongated body. The intermediate visual wear indicator is made of a third refractory material that differs in visual appearance from the first and second refractory materials between 800 and 1500 degrees C.

摘要： A metallurgical vessel having support brackets mounted on a vessel wall. The support brackets are mounted by a mounting system on a support body that does not completely surround the circumference of the vessel. The mounting system includes clamps that act on the support brackets. A coupling device is provided, which has, a first coupling component designed as a male part mounted on the support body and a second coupling component designed as a female part mounted on the vessel wall. The first and second coupling components are configured and arranged so as to automatically engage when the clamps are in the engaged position and to automatically disengage when the clamps are not in the engaged position. The coupling device has sealing elements and a coupling mechanism of the first coupling component relative to the second coupling component.

摘要： A gas purge device for a metallurgical melting vessel includes a conically shaped ceramic body (2) in contact at its top side with heat contained in the melting vessel. The ceramic body has a static external element and an internal element axially movable therein. A pneumatic drive axially moves the internal element to and fro relative to the external element between a closed position and an open position. The spring force of a spring retains the internal element in the closed position. The device furthermore includes a gas-tight enclosed volume arranged at the bottom side of the ceramic body the volume being connected to a gas supply duct for introduction of purge gas. A deformable membrane is connected to the internal element with the pressure difference between the purge gas pressure prevailing in the gas-tight enclosed volume and the ambient pressure acting upon the membrane.
