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.

Featured Primary Aluminum Products

KALA: The premier 50% alumina brick is designed to extend service life of combustion flues in carbon anode baking furnaces. Made from high purity materials with ultra-low alkali content, this brick exhibits superior resistance to subsidence at elevated temperatures.

ULTRA-GREEN® 45SR: Ideal for anode baking furnace flue caps, our 45% ultra-low cement castable combines excellent strength and corrosion resistance. Designed to be crack free after many thermal cycles.

HPV®-ESX CASTABLE: Designed to be used for port blocks on carbon anode bake furnaces that are exposed to thermal cycling, HPV-ESX CASTABLE is a fused silica based castable possessing high strength and excellent abrasion resistance.

VERSA-TECH MW 55 AR PLUS: A unique 55% alumina, low cement castable for flue caps utilizing HarbisonWalker International’s proprietary Middleweight technology. Great strength at only 125 pcf density allows this alkali resistant product to offer thermal efficiency without sacrificing durability.

CRYLA®: A 46% Alumina brick designed from high purity raw materials low in alkali content. This brick can be used for anode baking furnace fluewalls and offers an economical solution to extended service life over superduty materials.
