Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
89 words
A method of cooling a slab casting mold having opposed graphite side blocks, and a plurality of inner blocks engaged between said side blocks to define a casting cavity therebetween for the reception of molten metal, a plurality of substantially vertical bores through each side block, and means for spraying liquid coolant within said bores, said process comprising filling said casting cavity with molten metal in the absence of liquid coolant spraying and thereafter applying said liquid coolant spray until said side blocks have reached a desired lower temperature.
Claim 2
Independent Claim
89 words
A method of cooling a slab casting mold having opposed graphite side blocks, and a plurality of inner blocks engaged between said side blocks to define a casting cavity therebetween for the reception of molten metal, a plurality of substantially vertical bores through each side block, and means for spraying liquid coolant within said bores, said process comprising filling said casting cavity with molten metal in the absence of liquid coolant spraying and thereafter applying said liquid coolant spray until said side blocks have reached a desired lower temperature.
Claim 3
Dependent Claim
181 words
Apparatus for cooling a graphite block used in a mold assembly including a pair of opposed side blocks, and a top, bottom and end graphite blocks engaged between the side blocks to define therewith a casting cavity, said top block to define therewith a casting cavity, said top block being movable up and down upon separation of said side blocks to define a casting cavity of variable heights, said apparatus comprising a plurality of vertical bores extending through each side block and open at their upper and lower ends, a liquid coolant supply line extending downward from the top of at least one of said bores to a point intermediate the height thereof, means external of said side blocks for supplying liquid coolant to each of said lines, a spray nozzle connected to the end of each of said lines within said bore, said nozzle being so positioned and constructed as to cause a spray of liquid coolant to be directed toward and impinge said bore in an area below a line corresponding to the lowermost position of said top block.
Claim 4
Dependent Claim
181 words
Apparatus for cooling a graphite block used in a mold assembly including a pair of opposed side blocks, and a top, bottom and end graphite blocks engaged between the side blocks to define therewith a casting cavity, said top block to define therewith a casting cavity, said top block being movable up and down upon separation of said side blocks to define a casting cavity of variable heights, said apparatus comprising a plurality of vertical bores extending through each side block and open at their upper and lower ends, a liquid coolant supply line extending downward from the top of at least one of said bores to a point intermediate the height thereof, means external of said side blocks for supplying liquid coolant to each of said lines, a spray nozzle connected to the end of each of said lines within said bore, said nozzle being so positioned and constructed as to cause a spray of liquid coolant to be directed toward and impinge said bore in an area below a line corresponding to the lowermost position of said top block.
Claim 5
Dependent Claim
76 words
Apparatus for cooling a mold having a graphite block comprising a plurality of bores in said block extending from the top to the bottom thereof, a pipe extending within and along at least a portion of the length of a plurality of said bores, a plurality of transverse slits along the length of each pipe, said slits extending around less than half the circumference of the pipe, aNd means for supplying liquid coolant to said pipes.
Claim 6
Dependent Claim
76 words
Apparatus for cooling a mold having a graphite block comprising a plurality of bores in said block extending from the top to the bottom thereof, a pipe extending within and along at least a portion of the length of a plurality of said bores, a plurality of transverse slits along the length of each pipe, said slits extending around less than half the circumference of the pipe, aNd means for supplying liquid coolant to said pipes.
Claim 7
Independent Claim
31 words
A method for cooling a mold having a graphite block, which comprises providing a plurality of substantially vertical bores in the block and spraying coolant along spaced intervals within each bore.
Claim 8
Independent Claim
31 words
A method for cooling a mold having a graphite block, which comprises providing a plurality of substantially vertical bores in the block and spraying coolant along spaced intervals within each bore.
Claim 9
Dependent Claim
17 words
The method of claim 1 wherein the bores are provided along the longitudinal centerline of said block.
