Secondary Holding Furnace
The secondary holding furnace is used for continuous and batch-type pyro-metallurgical processes in non-ferrous metals, such as aluminum, production lines.











From a full range of castable refractories to industry-leading experts, Calderys accompanies you to select the best refractory solutions for your secondary aluminum holding furnace. Our goal is to provide peace of mind to the production team with proven quality refractory linings and high thermal insulation performance. Corrosion at the metal line from aluminum alloys and salts, mechanical erosion of the bottom hearth, metal contamination and degradation of door jambs and lintel are typical concerns Calderys will solve together with you. From fast repairs to full furnace refractory relining, contact our teams (and feel free to ask for our specific brochure on the secondary holding furnace).
