The invention relates to a wear indicator (display) in a compound system made of fireproof (refractory) ceramic bricks.

Wear indicator in a composite system of refractory ceramic stones

Gas purging element () for metallurgical applications, comprising the following features in its mounted state: a ceramic refractory body () with a lower end and an upper end, the upper end features an upper front surface, the lower end features a lower front surface (), a depression () extends from the lower front surface () into the lower end of the ceramic refractory body (), the depression () comprises a first part () of a detachable, form-fit connection to a gas connection element (), a fluidic connection for a treating gas through at least one gas permeable section () of the ceramic refractory body () is provided between the depression () and the upper front surface.

Gas purging element and associated gas connection element

The invention relates to a gas purging element at a metallurgical vessel as well as a corresponding gas supply pipe.

Gas purging element and associated gas feed line

A container for molten metal has at least one opening in which a refractory nozzle brick is mounted. A refractory purge plug or a refractory sleeve defining an outlet opening is inserted in the nozzle brick opening. A defined gap is formed between the nozzle brick opening and the purge plug or the sleeve and is filled with a refractory mass, this mass consisting of a material which can be easily bored or milled out of the mass for the purpose of replacing the purge plug or the sleeve. In this manner, laborious cleaning steps can be avoided and the nozzle brick no longer risks being damaged.

Method for exchangeably fastening a refractory purge plug or sleeve

The present invention relates to a tapping pipe for a metallurgical melting vessel, such as a converter or an arc furnace.
