Taphole clays

Since 2001, Lungmuß Feuerfest has been developing and supplying taphole mixes for the non-ferrous and ferro-alloy industry. The increased production requirements, in combination with new machine technology, have led to a growing demand for innovative taphole clays in several plants.

Our aim is to be able to offer clays for a wide range of tapping settings in electric arc furnaces and shaft furnaces. In close cooperation with the customer, we are able to optimize our product formulations as well as the tapping process in order to guarantee an optimal taphole performance as well as a long service life of the refractory lining. Variations in the machinery, the tapping temperatures and the tapping techniques lead to a need for customized taphole mixes to suit each application and furnace.

All taphole mixes used for these applications are very user-friendly. Due to the very low harmful substance content, especially regarding polycyclic aromatic hydrocarbons (PAH), these taphole clays can be safely used at all times. Moreover, the eco-friendly friendly binding system of these compounds makes both storage in the factory and the documentation of the use of the product significantly more convenient. The mixes of this new product range are also distinguished by their long shelf life and their stable product properties.

Currently, Lungmuß Feuerfest offers taphole clays for the following applications:

  • FerroNickel (FeNi)
  • FerroManganese (FeMn)
  • Ferrosilicon (FeSi)
  • Silicon metal (Si)
  • Silicomanganese (SiMn)
  • Ferrochrome (FeCr)
  • Ferrotitanium (FeTi)
  • Titanium oxide slag (TiO2)
  • Copper (Cu)
  • Lead (Pb)
  • Calcium carbide (CaC2)
