Abstract
Abstract The invention relates to a continuous casting plant wherein a cooling means is provided which includes, apart from customary nozzles, flat ray nozzles which are arranged at a distance of the slab guided in a supporting and guiding structure between rollers so as to be parallel to the width of said slab, the longitudinal axes of said flat ray nozzles extending parallel to the axes of the rollers. By means of these flat ray nozzles it becomes possible to spray the underside of the bar and the rollers in a uniform and plane manner. A satisfactory cooling is acheived also when the bar owing to skrinkage lifts off the rollers.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
98 words
A continuous casting plant for slabs comprising a watercooled mould from which the slab is continuously drawn out, a supporting and guiding structure including rollers between which the slab is guided, and a cooling means comprising nozzles through which a coolant is sprayed onto the slab and the rollers, and further comprising flat ray nozzles which are arranged at a distance of the slab so as to be parallel to the width of the slab for cooling the slab and the rollers, the longitudinal axes of said flat ray nozzles extending parallel to the axes of the rollers.
Claim 2
Dependent Claim
98 words
A continuous casting plant for slabs comprising a watercooled mould from which the slab is continuously drawn out, a supporting and guiding structure including rollers between which the slab is guided, and a cooling means comprising nozzles through which a coolant is sprayed onto the slab and the rollers, and further comprising flat ray nozzles which are arranged at a distance of the slab so as to be parallel to the width of the slab for cooling the slab and the rollers, the longitudinal axes of said flat ray nozzles extending parallel to the axes of the rollers.
Claim 3
Dependent Claim
23 words
The continuous casting plant set forth in claim 1, wherein the flat ray nozzles are arranged in the area of the slab edge.
Claim 4
Dependent Claim
27 words
The continuous casting plant set forth in claim 2, wherein said flat ray nozzles are arranged at both slab edges in a staggered manner opposite each other.
Claim 5
Dependent Claim
69 words
The continuous casting plant set forth in claim 1, wherein said supporting and guiding structure is an arcuate structure for deflecting the slab from an essentially vertical direction into an essentially horizontal direction, and wherein said flat ray nozzles are arranged in the area of the deflection which is regarded to amount to from one to two thirds of the longitudinal extension of the arcuate supporting and guiding structure.
Claim 6
Dependent Claim
33 words
The continuous casting plant set forth in claim 1, wherein said supporting and guiding structure is a horizontal structure and said flat ray nozzles are arranged at the under side of the slab.
