The invention relates to a heat treatment system, in particular a roller hearth furnace. The heat treatment system comprises a useful space having a first region with a width B1 and a second region with a width B2, wherein the rollers are arranged in the first region, and wherein width B2 is greater than width B1. In this context, "width" is understood to be the dimension that is transverse to the through-flow direction of the furnace. Width B1 is thereby measured such that the rollers have a length at which, even when there is a temperature in the furnace for the heat treatment of metal components, they still have such a mechanical stability, for example, that their bending remains within acceptable tolerances, even in the loaded state. The second region of the useful space extends above the first region of the useful space, with the greater width B2, such that components with a maximum width B2, greater than width B1, can also be heat treated. |
