Primary aluminum producers need anode baking furnace refractory solutions that improve production processes, increase overall output and reduce the cost of making high-quality primary aluminum for use in transportation, construction and packaging industries worldwide.
Primary Aluminum Refractory Solutions
As a primary supplier to some of the world’s largest aluminum producers, HarbisonWalker International has the process knowledge, proven refractory products, and solutions that deliver energy savings, increased campaign life, and efficiency within a primary aluminum plant.
Primary aluminum production takes place in smelting facilities where an electrolytic process reduces aluminum oxide found in bauxite ore to aluminum. Our customized refractory linings are used in all key primary aluminum production process areas: carbon anode baking furnaces, pot linings, casthouse furnaces and metal transportation. Our proven refractory product line of brick and monolithics provide the highest performance in the most severe environments.
Today’s primary aluminum melting and holding furnaces are continuously being pushed harder to produce more metal in shorter times — requiring primary aluminum refractories to withstand more intense demands. HWI refractory solutions address all of the factors that can contribute to degradation of refractories and refractory linings.
