HWI supports customers in the primary and secondary copper and heavy non-ferrous industries across the globe. HWI was the first to introduce chrome alumina refractories to the industry. We also pioneered technology to help optimize the life of our customers’ units through specific application of products that provide extreme protection in select high-wear areas. This innovative design has extended the campaign life of many of our customers’ units.

We provide world-class products, in-depth consultation, and problem solving that enhance our customers’ overall operations. Our dedicated application specialists have deep experience recognizing and addressing process reactions that can take a toll on refractory performance.

Refractory solutions are available in a variety of leading brick and castable formulations that combat high temperatures as well as the erosive and corrosive effects of slag. We specially engineer products to meet the specific lining demands of primary smelting, anode, and secondary copper furnaces, as well as copper converters. We also have products tailored to the needs of secondary lead and brass processes.

Customers Find Financial Success with AUREX® 30 SR.

In 2015, a US secondary copper recycling plant installed AUREX® 30 SR instead of conventional magnesia-chrome products. The plant was able to triple the life of the furnace lining in the high-wear slagline. This led to significant production efficiencies and annual revenue increases.
