When a unit is refractory lined, Hotwork can fire to the manufacturer's recommended schedule, to thoroughly dry refractories without spalling or cracking.

Hotwork is the pioneer of the convective heating process, which simplifies refractory dryouts and heatups. The one-sided drying of monolithic refractories is an extremely complex transient heat and mass transfer phenomenon which includes chemical reactions throughout the dryout. Moisture trapped in a refractory lining after a furnace or vessel rebuild is especially detrimental to optimum refractory performance.

Hotwork's convective heating method utilizes rapid heat transfer at all temperature levels. Our burners produce high velocity combustion, which is accurately controlled from ambient to temperatures in excess of 2500°F (1370°C). This high discharge rate circulates the products of combustion evenly throughout the vessel, regardless of size and configuration, producing overall temperature uniformity.
