General Description

The continuous multiple strands of steel wire pass horizontally through a bed of fluidized aluminum oxide particles. Air and gas are introduced in the bottom of the bed through a double distribution network. Combustion occurs within the bed providing rapid heat-transfer to the sand particles and wires. The bed is contained between corrugated retort walls of high nickel alloy steel that are suitably designed to withstand the stresses of thermal cycling. The walls are insulated with layers of ceramic fiber to provide a low skin temperature and efficient operation. The furnace frame is constructed of welded structural steel sections and heavy gauge panels. Most furnaces are custom built in length and width to suit the customer’s production requirement.
