Abstract
Abstract A continuously cast strand as it leaves the casting mold is cooled by cooling elements comprising cooling plates having surfaces spaced from the strand by guide elements, preferably adjustable, which protrude from the surfaces of the plates to engage the surface of the strand and establish and maintain a gap between the strand surface and the plate surfaces to permit flow of coolant introduced into the gap through said plates.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
86 words
Apparatus for cooling continuously cast steel strands with cooling elements comprising cooling plates having surfaces conforming to and facing opposed strand surfaces, said plates being provided with apertures through which coolants are applied directly to said opposed surfaces of the casting, and guide elements carried by said plates and protruding from said cooling plate surfaces and engaging said opposed surfaces of the casting to maintain a cooling gap between said cooling plate surfaces and said opposed surfaces of the casting through which said coolants may flow.
Claim 2
Dependent Claim
86 words
Apparatus for cooling continuously cast steel strands with cooling elements comprising cooling plates having surfaces conforming to and facing opposed strand surfaces, said plates being provided with apertures through which coolants are applied directly to said opposed surfaces of the casting, and guide elements carried by said plates and protruding from said cooling plate surfaces and engaging said opposed surfaces of the casting to maintain a cooling gap between said cooling plate surfaces and said opposed surfaces of the casting through which said coolants may flow.
Claim 3
Dependent Claim
30 words
Apparatus according to claim 1, in which the guide elements which are spaced consecutively in the direction of travel of the casting are offset transversely to each other without overlapping.
Claim 4
Dependent Claim
19 words
Apparatus according to claim 1, in which the guide elements are set screws extending through the said cooling plates.
Claim 5
Dependent Claim
21 words
Apparatus according to claim 3, in which said set screws are provided with passages for admitting coolant into the cooling gap.
Claim 6
Dependent Claim
25 words
Apparatus according to claim 4, in which the said coolant passages are located on the downstream side of the set screws in strand travel direction.
Claim 7
Dependent Claim
52 words
Apparatus according to claim 1, in which guide elements are in the form of strips having faces which extend parallel to the direction of travel of the strand, and in which said strips are separated by grooves having recessed faces set back from said strip faces by the desired cooling gap width.
Claim 8
Dependent Claim
27 words
Apparatus according to claim 6, in which the total area of the surfaces of said strips is approximately equal to the total area of said recessed faces.
Claim 9
Dependent Claim
17 words
Apparatus according to claim 1, in which said cooling elements comprise a plurality of component cooling plates.
Claim 10
Dependent Claim
15 words
Apparatus according to claim 8, in which the said component cooling plates are spaced laterally.
