ANH Refractories Group manufactures and supplies a full line of refractories to support the most demanding copper industry applications. We specially engineer products to meet the specific lining demands of primary smelting, anode, and secondary copper furnaces as well as copper converters.
Refractory solutions are available from our US operation in a variety of leading brick and castable formulations that combat high temperatures and the erosive and corrosive effects of slag. In primary smelting vessels, the use of direct-bonded chrome-magnesite refractories like NARMAG HNF 27 and NARMAG HNF 31 are used. Anode furnaces require the use of low porosity, low silica refractories also. TBRC''s require the use of high purity, high strength, fused grain refractories like NARMAG FG. Areas that are difficult to brick in these furnaces often use alumina-chrome monolithic refractories like phosphate bonded JADEPAK 88P or other castables which are available from the UK (see below).
In the UK we manufacture a range of Silicon Carbide & Vitrified Silica monolithics of which some have been successfully used in the Copper Industry. (Highlighted in orange)
Silicon Carbide Materials
ANH have a variety of monolithic products suitable for the production of Ferro Alloys.
Our most successful application has been with the supply of precast/prefired blocks with life times of 12 months plus.
These blocks were manufactured in a FIBRE REINFORCED CERAMIC COMPOSITE (FRCC).
