Title:
METHOD AND DEVICE FOR COOLING CONTINUOUSLY RUNNING-THROUGH MATERIAL
Document Type and Number:
WIPO Patent Application WO/2013/020793
Kind Code:
A3
Abstract:
The invention relates to a method for cooling continuously running-through material (1), comprising at least the following steps: a) using a cover (4) to form a gap (2) over at least one part of a surface (3) of the running-through material (1), b) feeding cold-liquefied cooling gas (5) to the gap (2), the volume of the cold-liquefied cooling gas (5) in the gap (2) being increased as a consequence of at least one change in the state of aggregation to gaseous cooling gas (5), c) acceleration of a flow velocity of the gaseous cooling gas (5) as a result of the increase in volume of the cold-liquefied cooling gas (5) in the gap (2) to a multiple of a running-through velocity of the continuously running-through material (1), d) cooling of the at least one part of the surface (3) of the running-through material (1) by the cooling gas (5). This allows heat-treated running-through material (1) to be cooled down to approximately ambient temperature quickly, effectively and over a short length, of for example approximately 80 cm, and directly further processed.
