Reheating furnace

CEA Group designs, builds and installs furnaces with upper and lower heating, to be inserted in the rolling lines for heating slabs, blooms at the appropriate temperature (1,100 / 1,250 C°) for the subsequent rolling process.

The continuous passage furnace with active pit consists of: walls, vault, pit, fixed beams (cooled and lined with refractory) and “skids”, regenerative burners (placed both above and below the load).

The unloading system can be front or side, depending on the layout of the plant. Compared to the pusher furnace with unilateral heating, this type of system allows shorter furnace lengths.
