High-Temperature Mechanical Characterisation of In-Situ Forming Spinel-Alumina Castables Using Magnesia or Magnesite as Raw Material

In this work, four alumina-magnesia, cement-bonded castables were tested at high temperature. Strength was determined by bending test at temperature ranging from room temperature to 1550 °C. As a reference, a high alumina castable was also investigated.

Post-Mortem Investigation of a Steel Ladle Repair Mix Containing Porous Calcium Magnesium Aluminate Aggregates

Monolithic ladle linings are cost efficient and environmentally friendly because a significant part of the used ladle lining can remain inside the ladle for a long time while only the effectively worn out part needs to be replaced by a repair mix.

Refratechnik and QMAG Follow a Common Path

In January 2020, Refratechnik Holding GmbH/DE entered a purchase agreement with SIBELCO Group to take over 100 % of QMAG Ltd.

Refractories for Non-Ferrous Metals

Principal non-ferrous metals

Although the combined needs of the global iron and steel industry still continue to dominate the market, the cement and glass industries refractories requirements are also increasing, and although the needs of the non-ferrous industries are relatively small in comparison, they can still provide a valuable niche market for refractories producers, looking for regular repeat business across a wide range of refrac tories materials and product types.

Gunning Manipulators for the Hot Repair

Mobile lance trolley for ladle gunning

For many years, the gunning procedure is used for the repair of refractory linings. In combination with a gunning manipulator furnaces, ladles or RH­degasser legs can be repaired in hot condition. The advan­tages of the hot repair are: higher gunning rates giving shorter repair times, higher quality of application, less physical strain on operators, and lower risk of accidents. Via integrated TV cameras, the gunning repair can be performed from the operator pulpit, and the gunning can be recorded for quality control.
