Abstract
Abstract Continuously cast metal, such as steel, ingots are supported and cooled while being displaced along a path on a panel comprised of alternating support bars and cooling fluid spray banks extending parallel to each other transversely to the path of displacement. The spray banks are mounted individually and removably on the panel.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
155 words
An apparatus for supporting and cooling a continuously cast product having a surface while the product is displaced along a path, comprising 1. a series of substantially identical support bars extending substantially parallel to each other in a direction transverse to the path of displacement, a. the support bars being dismountably assembled to form a panel, and b. each bar including a portion of rectangular cross section having a large face and a small face, the large face extending perpendicularly to the surface of the cast product and the small face being arranged in contact with the surface of the cast product to support the product, the width of the small faces of the bar portions being substantially less than the spacing therebetween; and 2. elongated means for spraying a cooling fluid disposed substantially parallel to each other on the panel and between the support bars, the elongated spraying means being supported by the panel.
Claim 2
Independent Claim
155 words
An apparatus for supporting and cooling a continuously cast product having a surface while the product is displaced along a path, comprising 1. a series of substantially identical support bars extending substantially parallel to each other in a direction transverse to the path of displacement, a. the support bars being dismountably assembled to form a panel, and b. each bar including a portion of rectangular cross section having a large face and a small face, the large face extending perpendicularly to the surface of the cast product and the small face being arranged in contact with the surface of the cast product to support the product, the width of the small faces of the bar portions being substantially less than the spacing therebetween; and 2. elongated means for spraying a cooling fluid disposed substantially parallel to each other on the panel and between the support bars, the elongated spraying means being supported by the panel.
Claim 3
Dependent Claim
31 words
The apparatus of claim 1, further comprising ribs extending from the support bars in the direction of the path, the cooling fluid spraying means being carried by the support bar ribs.
Claim 4
Dependent Claim
20 words
The apparatus of claim 2, wherein the support bar ribs define aligned recessed forming lingitudinal seats for the spraying means.
Claim 5
Dependent Claim
51 words
The apparatus of claim 1, further comprising two divergent deflectors, the deflectors being disposed on respective sides of the spraying means and dividing the space between two support bars into a central zone wherein the cooling fluid enters and two lateral zones wherethrough vapors from the spent cooling fluid are evacuated.
Claim 6
Dependent Claim
14 words
The apparatus of claim 4, wherein the deflectors are affixed to the support bars.
Claim 7
Dependent Claim
12 words
The apparatus of claim 1, wherein the support bars are inverted T-bars.
Claim 8
Dependent Claim
23 words
The apparatus of claim 1, wherein the support bars have base portions defining port means facilitating evacuation of vapors from spent cooling fluid.
Claim 9
Dependent Claim
19 words
The apparatus of claim 1, wherein the small support faces of the support bar portions have grooves formed therein.
Claim 10
Dependent Claim
31 words
The apparatus of claim 1, wherein the support bars and spraying means are V-shaped, the point of the V being directed upstream in the path of displacement of the cast product.
Claim 11
Dependent Claim
50 words
The apparatus of claim 1, further comprising small diameter tubes directed towards the leading edge of the small support faces of the support bar portions, in the direction of displacement of the cast product, and means for delivering compressed air to the tubes to remove liquid from the leading edges.
Claim 12
Dependent Claim
43 words
The apparatus of claim 10, wherein the means for delivering compressed air comprises a chamber extending the length of the spraying means and supplied with compressed air, and the small diameter tubes are mounted on the spraying means in communication with the chamber.
Claim 13
Dependent Claim
27 words
The apparatus of claim 1, wherein the small faces of the support bars extend in a direction transverse to the path of displacement of the cast product.
Claim 14
Dependent Claim
41 words
The apparatus of claim 1, wherein the small faces of the support bars extend in the direction of displacement of the cast product and a plurality of said small support faces are spaced along the length of each of said bars.
Claim 15
Dependent Claim
31 words
The apparatus of claim 13, wherein the spacing between the small support faces of each support bar is of the same order of magnitude as the spacing between the support bars.
Claim 16
Dependent Claim
16 words
The apparatus of claim 13, wherein the small support faces of the support bars are aligned.
Claim 17
Dependent Claim
29 words
The apparatus of claim 13, wherein the small support faces of the support bars are offset from each other in the direction of the displacement of the cast product.
Claim 18
Dependent Claim
59 words
The apparatus of claim 13, wherein each support bar has a portion extending in a direction transverse to the path of displacement of the cast product and a series of ribs extending transversely to said support bar portion, the height of the ribs exceeding the height of the support bar portion and the ribs having said small support faces.
Claim 19
Dependent Claim
50 words
The apparatus of claim 13, wherein each support bar is comprised of two elongate webs spaced from each other and interconnected by a series of ribs extending transversely to the webs, the height of the ribs exceeding the height of the webs and the ribs having said small support faces.
Claim 20
Dependent Claim
17 words
The apparatus of claim 18, wherein the webs converge towards a median plane of the support bar.
Claim 21
Dependent Claim
12 words
The apparatus of claim 1, wherein the small support faces are plane.
Claim 22
Dependent Claim
12 words
The apparatus of claim 1, wherein the small support faces are convex.
Claim 23
Dependent Claim
39 words
The apparatus of claim 21, arranged in a curved portion of the path of displacement of the cast product, the radius of curvature of the convex support faces being less than the radius of curvature of the curved path.
Claim 24
Dependent Claim
24 words
The apparatus of claim 1, wherein each support bar is formed by two identical halves disposed symmetrically in respect of a plane of symmetry.
Claim 25
Dependent Claim
31 words
The apparatus of claim 1, wherein the support bars are assembled in series and further comprising tie rod means passing through the ends of the assembled bars for forming the panel.
