Benefits of technology
The present invention provides an improved hood assembly for controllably cooling extruded section members of aluminum and other metal materials. The hood assembly is designed to cool down the hot extruded aluminum section members more efficiently. This results in faster production times and better quality products.
Problems solved by technology
The above prior hood assemblies have the drawback of a poor operation efficiency and a comparatively large length thereby requiring high air flow rates to provide a satisfactory cooling.
This, in turn, involves a very high power drain, and a use of a large length hood assembly, of a correspondingly large size.

Embodiment Construction
[0012]With reference to the number references of the mentioned figures, the improved hood assembly 1 for controllably cooling extruded section members 2 of aluminium and other metal materials coming from an extruding line according to the present invention is characterized in that it comprises a plurality of air delivery mouth or outlet portions 5, inclined at angles varying from 20° to 60° with respect to the longitudinal sliding direction on the section members 2 on corresponding sliding rollers 3 along a cooling line 4.
[0013]More specifically, the inventive hood assembly 1 comprises cooling air ducts 5, said cooling air being sucked or drawn from an outside environment and being conveyed to the hood assembly.
[0014]Said cooling air mouth portions 5 according to the present invention are not arranged perpendicular to the section member to be cooled sliding direction, but are inclined at an angle from 20° to 60°.
[0015]Preferably, the slanting of the air conveying mouth portions 5, f...

Abstract
An improved hood assembly for controllably cooling extruded section members of aluminium and other metal materials at an output of an extruding line therefor, characterized in that said hood assembly comprises a plurality of air delivery spouts inclined according to angles varying from 20° to 60° with respect to a sliding longitudinal direction of said section member through said cooling line.
Description
BACKGROUND OF THE INVENTION[0001]The present invention relates to an improved hood assembly for controllably cooling extruded section members of aluminium and other metal materials at an output of an extruding line therefor.[0002]As is known, hood assemblies for cooling by air flows aluminium extruded section members exiting extrusion lines at a very high temperature are already known.[0003]However, prior hood assemblies comprise a plurality of ducts which are arranged perpendicular to the extruded aluminium section member feeding direction.[0004]The above prior hood assemblies have the drawback of a poor operation efficiency and a comparatively large length thereby requiring high air flow rates to provide a satisfactory cooling.[0005]This, in turn, involves a very high power drain, and a use of a large length hood assembly, of a correspondingly large size.SUMMARY OF THE INVENTION[0006]Accordingly, the main object of the present invention is to provide such an improved hood assembly...
