Abstract
A roller hearth furnace (1) is subdivided into detachably assembled sections (2). In order to clean the rollers, one of the sections (2) of the assembly is removed and replaced by a replacement section (7) previously heated to the furnace operating temperature. The section (2) removed can therefore cool before being cleaned. The sections (2, 7) are transported along a stretch of rails (3) parallel to the roller hearth furnace (1).
