Abstract
Abstract The disclosure relates to a method and to an apparatus for cooling continuously cast webs of metal. Several coolant jets are produced continuously and at least two jets are projected to a hotter, slowly cooling zone of the surface of the webs.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
28 words
A method according to claim 1, further characterized in that a. three fan jet streams are merged approximately at a point of intersection adjacent to the web surface.
Claim 2
Dependent Claim
25 words
A method according to claim 2, further characterized in that a. the fan jet sprays extend transversely of the direction of movement of the web.
Claim 3
Dependent Claim
26 words
A method according to claim 3, further characterized in that a. the jet fans produce cross-sectional projection patterns ranging from generally stripe-shaped to oblong oval shaped.
Claim 4
Dependent Claim
27 words
A method according to claim 4, further characterized in that a. sprays of different fans are directed upon the surface of the web from different elevations thereabove.
Claim 5
Dependent Claim
50 words
A method according to claim 5, further characterized in that a. the angles of the jet fans are adjusted in predetermined relation to each other and/or to the surface of the web to distribute coolant in suitably weighted quantities commensurate with the corresponding required cooling intensity increments across the web.
Claim 6
Dependent Claim
30 words
A method according to claim 6, further characterized in that a. the quantitative output of the jets in individual fans is readily adjustable to compensate for variations of cooling requirements.
