Batch Heat Treatment Furnaces
Fixed
Hearth Furnaces
Many furnaces are of the fixed hearth style, whereby the hearths are constructed from castellated piers. This type of furnace is common when a number of furnaces are positioned side by side, thus enabling a single charging machine to load and unload any number of furnaces.
The furnace illustrated is for the Firth Rixson Group, who manufacture components for the automotive and aerospace industries.
Temperature uniformity is
absolutely critical and, to achieve the desired results, flues are usually taken
through the hearth and piered structure.
