Molten Metal Furnaces are most often lined with seamless cast, gunned or rammed refractory. This refractory is very dense and impermeable to resist metal penetration. This impermeability can cause damaging steam pressures to build up during the initial dryout when the residual moisture is driven off. The Hotwork convective heating process helps prevent premature refractory failure by eliminating localized overheating and thermal shock during initial dryout and preheating.

In addition to Refractory Dryout & Heatup, Hotwork also provides Temperature Holds to the Aluminum/Nonferrous Metals industries.
