Abstract
Abstract In a method of cooling continuously cast billets of polygonal cross section the surfaces of the casting are sprayed with coolant from atomizing nozzles as it leaves the mold. The sides adjacent the edges are sprayed by nozzles having a relatively high-average delivery per unit area in an approximately rectangular pattern; the central portions of the sides are sprayed with nozzles of relatively low-average delivery and a spray delivery that decreases toward the edge regions.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
96 words
A method of cooling a continuous casting of polygonal cross section issuing from a continuous casting mold, which comprises spraying the surface of the casting directly after it leaves the mold with a coolant liquid sprayed through atomizing nozzles, wherein the regions on each side of the casting adjacent the edges are sprayed by nozzles having a relatively high-average delivery per unit area and an approximately rectangular spray pattern, and the surface between the edge regions is sprayed by nozzles of relatively lower average delivery and a spray delivery characteristic that decreases towards the edge regions.
Claim 2
Independent Claim
96 words
A method of cooling a continuous casting of polygonal cross section issuing from a continuous casting mold, which comprises spraying the surface of the casting directly after it leaves the mold with a coolant liquid sprayed through atomizing nozzles, wherein the regions on each side of the casting adjacent the edges are sprayed by nozzles having a relatively high-average delivery per unit area and an approximately rectangular spray pattern, and the surface between the edge regions is sprayed by nozzles of relatively lower average delivery and a spray delivery characteristic that decreases towards the edge regions.
Claim 3
Dependent Claim
30 words
A method according to claim 1, wherein the nozzles spraying the edge regions spray strips extending from the edge a distance of about 10 to 25 mm. across the side.
Claim 4
Dependent Claim
17 words
A method according to claim 1, wherein the rectangular spray pattern is generated by flat-type spray nozzles.
Claim 5
Dependent Claim
46 words
A method according to claim 1, wherein the rectangular spray pattern in two edge regions with a common edge is generated by two narrow sprays issuing from one body of a flat-type nozzle and that the nozzle is located on a line bisecting the corner angle.
Claim 6
Dependent Claim
20 words
A method according to claim 1, wherein the nozzles cooling the surface between the edge regions spray approximately square areas.
