Product category: Refractory ramming mixtures


Throughout Europe Lungmuß‘ taphole clays stand for high quality and the latest technology. After the start with basic tar-bonded clays in the beginning of the 70’s Lungmuß Feuerfest produces since 1982 exclusively resin-bonded taphole clays. All taphole clays are low in PAH content. Since 2015 the company is also offering a superior binding system almost free of PAH. In the field of taphole clays, Lungmuß Feuerfest is truly the European market leader.

Lungmuß‘ taphole clays can be used for soaking bar and for drilling technique. The development using different resin qualities leads to variable setting times of the clay. Thus Lungmuß’ taphole clays can also be used with uncooled mud guns. Currently these clays are used for blast furnaces with a hearth diameter between 6.0 m to 15.1 m. At a single taphole operation with tap-to-tap time between 20 and 60 minutes, the daily production per taphole is between 2,000 to 13,500 t HM. For maintenance purposes the company offers different types of repair material for the taphole area.
