Due to the low production capacity of the nonferrous metallurgy industry, the consumption rate of refractories is not as high as it is in the iron & steel sector. However, the refractory materials used have unique characteristics for each processing unit.

Aluminium: Haznedar Durer’s products achieve very high performance levels in the aluminium industry. The non-wetting high alumina low cement castables for the bath area of both melting and holding furnaces have long operational lives. Additionally, the low cement castables & regular castables used for all parts above the metal level that requires relatively higher thermal shock resistance yield very satisfactory results. Beside the working lining of aluminum furnaces, Haznedar Durer also provides insulating castables that have a servicing temperature around 1100-1300°C as back up lining. These insulating castables are made of light chamotte, perlite & vermiculite and may be applied by casting and gunning alike. Usage of bauxite based high alumina bricks are also preferred in aluminium production.

Copper: Haznedar Durer products such as low cement super alumina castable and low cement castables, containing SiC& ZrO2 and are based on bauxite and andalusite, have been giving highly successful results in the coreless induction furnaces above the inductor level. Usage of high quality chrome magnesite bricks are also preferred in the copper industry.
Lead: Usage of high quality chrome magnesite refractories are preferred for lead processors.
