Atoor Refractories Co. offers a complete line of metallic and ceramic anchors to secure monolithic installation. The proper selection and spacing of these anchors is an essential criteria to obtain the stability of lining.
Metallic anchors are the most common anchoring devices used due to their low cost and easy installation. Metallic anchors are used when service temperature do not exceed 1100°C, at higher temperatures ceramic anchors are recommended. The thickness and dimension of metallic anchors depends on the type of refractory material, lining thickness and process conditions such as temperature and chemical environment.

Choosing the right anchor alloy is critical. Considering the working condition is cement industry, Atoor Refractories recommends using
AISI 304,
310 and
253 MA alloys for anchoring. For selecting the right anchor material according to your specific requirements please contact us for professional advice.
Ceramic Anchors
Whenever there is a very high temperature in the furnace lining or a severe corrosive attack is to be expected, ceramic anchors are recommended. Ceramic anchors are placed in walls, roofs, arches and noses to provide support for the refractory mass. Atoor Refractoris Co. makes various lengths of ceramic anchors based on andalusite which has an excellent thermal shock resistance. The brick shape, with its grooves and rises, provides excellent retention power over the monolithic lining.
