Taphole clays

Lungmuß Feuerfest has been developing and supplying taphole compounds for the non-ferrous and ferro-alloy industry since 2001. The increased production requirements, in conjunction 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 optimise 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 customised taphole mixes to suit each application and furnace.

All taphole clays used for these applications are extremely 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 binding system of these compounds makes both storage in the plant and the documentation of the use of the product significantly more convenient.

The compounds 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)

Concrete for ladles and runners

Lungmuß Feuerfest has developed a multitude of high-quality concretes for the numerous special applications of its customers. These have proven to offer long lifetimes, resulting in low specific costs.

In addition, Lungmuß Feuerfest offers:

  • Individual insulation and lining concepts for optimised energy balance and casting quality
  • Complete lining and drying monitoring on-site by deploying its own service technicians
  • Complete lining and drying service of our customers’ ladles and runners is also performed in our prefabricated parts department.

Prefabricated parts

In order to ensure the ultimate use of prefabricated parts at the customer’s site, Lungmuß Feuerfest uses decades of experience and know-how. The engineering department generates technical concepts and develops optimised solutions for specific refractory applications. The main focus is the reduction of lining and drying times as well as the improvement of the refractory life.
