INTOCAST Sees Additional Market Potential with further External Growth

by

INTOCAST AG makes refractory products at a total of 23 sites, including eight in Germany. INTOCAST is one of the few manufacturers to cover its customers’ entire range of demand for shaped and unshaped refractories as well as casting auxiliaries and metallurgical slag additives. The user industries include, alongside the iron and steel industry, the producers of non-ferrous metals (especially aluminium), foundries, the cement and ceramics industry as well as the chemicals and petrochemicals industry. Moreover, INTOCAST products are used in power plants, thermal treatment furnaces and incineration plants.

Gunning Manipulators for the Hot Repair

by

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.

Refractories for Non-Ferrous Metals

by

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.

Thermal Management of Heating Processes – Measuring Heat Transfer Properties

by

The design of any heating process is based on a careful thermal management of heat transfer. A necessary prerequisite for this thermal management is the precise knowledge of thermal material properties. Need for improvements exist especially at high temperatures, where measurements of quantities like thermal conductivity or specific heat are difficult.

Morphology Evolution of the Hydration Products of Hydratable Aluminas at 40 °C

by

Hydratable Alumina (HA) is an important CaO-free hydration binder for no-cement castables. Different sources of hydratable alumina have varied phase compositions and physical properties (such as specific surface area and particle size), which could generate hydration products with different phases and structures during hydration.

Imerys Simplifies its Organization for Greater Customer Focus

by

Following an in-depth strategic review, Imerys announced that it will change its management organization to be more market-focused and to further leverage its successful repositioning as a specialty minerals company. The new organization, effective 1 December 2018, is organized around two segments, grouping five newly created business areas which have been built around core markets.
