INSURAL ATL insulating ladle linings are suitable for aluminium and zinc foundries. They are supplied ready for use, to transport molten aluminium and zinc alloys. A variety of shapes and sizes are available up to a maximum of 2 tonnes for both standard and non-standard steel ladle shells. INSURAL ladle linings are made from a strong, lightweight and non-wetting refractory material with excellent insulation properties. INSURAL 140 refractory is used for the walls and the more wear resistant silicon carbide for the base. Supplied as ready for use units, they require only a brief pre-heating following installation to remove any possible moisture pick-up. After this, further pre-heat before use is only necessary if the ladle has remained empty and cold over fairly prolonged periods.
