Abstract
Abstract An apparatus for cooling a stress sensitive continuous casting emerging from a mold. The apparatus is particularly applicable to aluminum base alloys when cast in the horizontal mode. The apparatus includes means for applying a first cooling medium to an outer surface of the mold and the emergent portion of the casting; means for removing the first cooling medium from the casting; means spaced from the removing means for applying a second cooling medium to the casting; and means for removing the second cooling medium.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
155 words
An apparatus for cooling a stress sensitive continuous casting emerging in a substantially horizontal direction, from a mold, comprising: A. a first coolant applying means for applying a first cooling medium in a continuous circumferential sheet to an outer surface of the mold and the emerging portion of the casting; B. a first coolant removing means, spaced from said first coolant applying means in the direction of the casting movement, for removing substantially all of said first cooling medium from said casting; C. means to expose the casting to the ambient atmosphere; D. a second coolant applying means spaced from said first coolant removing means in the direction of the movement, for applying a second cooling medium to said casting after exposure to said ambient atmosphere; and E. a second coolant removing means spaced from said second coolant applying means in the direction of the casting movement for removing said cooling medium from said casting.
Claim 2
Independent Claim
155 words
An apparatus for cooling a stress sensitive continuous casting emerging in a substantially horizontal direction, from a mold, comprising: A. a first coolant applying means for applying a first cooling medium in a continuous circumferential sheet to an outer surface of the mold and the emerging portion of the casting; B. a first coolant removing means, spaced from said first coolant applying means in the direction of the casting movement, for removing substantially all of said first cooling medium from said casting; C. means to expose the casting to the ambient atmosphere; D. a second coolant applying means spaced from said first coolant removing means in the direction of the movement, for applying a second cooling medium to said casting after exposure to said ambient atmosphere; and E. a second coolant removing means spaced from said second coolant applying means in the direction of the casting movement for removing said cooling medium from said casting.
Claim 3
Dependent Claim
33 words
An apparatus as in claim 1 in which the means for applying said first cooling medium comprises a spray box having a circumferential baffle, said circumferential baffle having a plurality of openings therein.
Claim 4
Dependent Claim
37 words
An apparatus as in claim 2 in which said spray box is provided with a plate affixed to said spray box, said plate being so shaped as to regulate the direction and pressure of applied cooling medium.
Claim 5
Dependent Claim
22 words
An apparatus as in claim 3 in which said plate has a portion of reduced thickness which regulates said first cooling medium.
Claim 6
Dependent Claim
20 words
An apparatus as in claim 4 in which said spray box contains a circumferential header in addition to said baffle.
Claim 7
Dependent Claim
56 words
An apparatus as in claim 5 wherein said means for removing said first cooling medium comprises: at least one rubber wiper adapted to contact the periphery of the casting, said wiper being held in position by at least one holder, means for supporting said holder so that said wiper can engage the periphery of said casting.
Claim 8
Dependent Claim
14 words
An apparatus as in claim 6 in which a plurality of wipers are provided.
Claim 9
Dependent Claim
45 words
An apparatus as in claim 7 further including a concentric tube having a plurality of orifices and means for introducing a gas under pressure into said tube whereby said gas exits from said orifices to remove said first cooling medium not removed by said wiper.
Claim 10
Dependent Claim
28 words
An apparatus as in claim 8 in which the orifices are at an angle of 30* to 60* with respect to a plane passing through said concentric tube.
Claim 11
Dependent Claim
27 words
An apparatus as in claim 9 in which said wipers, said concentric tube, and said means for applying said second cooling means are positioned within a chamber.
Claim 12
Dependent Claim
47 words
An apparatus as in claim 10 wherein said means for applying said second cooling medium to said casting comprises: a header; means for introducing a cooling medium into said header; said header having a plurality of openings therein for applying said second cooling medium to said casting.
Claim 13
Dependent Claim
25 words
An apparatus as in claim 11 wherein said openings are at an angle of 15* to 45* with respect to the surface of the casting.
Claim 14
Dependent Claim
55 words
An apparatus as in claim 12 wherein said means for removing said second cooling medium comprises at least one rubber wiper contacting the periphery of said casting, said wiper being held in position by at least one holder; and means for supporting said holder so that said wiper can engage the periphery of said casting.
