Abstract
A device for preheating rod-like, metal workpieces, in particular aluminium rods, by means of a fluid flow heated by residual heat or waste heat of a combustion process occurring in a heating device for heating the workpieces. The device has a preheating chamber for receiving at least one workpiece, wherein, in order to transfer the heat from the fluid flow to a heat transfer medium flow in a fluid flow line between a fluid flow connection and the preheating chamber, a heat-exchanger unit is provided in such a way that the workpiece is preheated indirectly via the heat transfer medium flow heated in the heat-exchanger unit by the fluid flow.
Claims19
A device for preheating rod-shaped, metallic workpieces (24) by means of a fluid flow heated by residual or waste heat of a combustion process taking place in a heating device for heating the workpieces (24), the device having a preheating chamber (12) for receiving at least one workpiece (24), wherein,
- in order to transfer the heat from the fluid flow to a heat transfer medium flow, a heat exchanger device (11) beings provided between a fluid flow connection (14) and the preheating chamber (12) in a fluid flow line (15) in such a manner that the workpiece (24) is preheated indirectly via the heat transfer medium flow heated by the fluid flow in the heat exchanger device (11) and the liquid discharge device (25) extending parallel to the longitudinal axis (L) of the workpiece (24) disposed in the reception area (23) of the preheating chamber (12)
- characterized in that
- the liquid discharge device (25) has a row of discharge openings (28) for realizing a substantially continuous wetting on the upper side (26) of the workpiece (24), the row of discharge openings (28) extending in the longitudinal direction of the preheating chamber (12).
