Abstract
Abstract A twin-belt continuous metal casting machine is described having a pair of removable core assemblies each comprising coolant applicators and back-up rollers for supporting and cooling the respective casting belts. These removable core assemblies are fitted into large open channels in the respective upper and lower belt carriages adjacent to the region in which the molten metal is solidified. The core assemblies are conveniently removable for inspection and maintenance, and they are pre-assembled separately from the machine to facilitate accurate assembly and alignment of the segmented finned back-up roller assemblies and coolant applicators which include rigid rectangular conduits serving as transverse stiffening beams in the core assemblies.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
170 words
In a twin-belt continuous metal casting machine having casting belts revolving around two belt supporting carriages for defining a casting region between the belts, and wherein each of the carriages has a frame with main rolls located at opposite ends of the carriage for revolving the casting belt around the carriage, the invention comprising: a removable core assembly for insertion into each belt carriage including a plurality of coolant applicators having coolant conduits extending transversely across the core assembly for applying liquid coolant to a casting belt and a plurality of finned back-up rollers extending transversely for supporting and guiding the casting belt adjacent to the casting region, the frames of each of the carriages defining a large channel opening on the side of the carriage facing toward the casting region for receiving the core assembly inserted therein, means for removably connecting each of said coolant conduits to a supply of liquid coolant in the casting machine, and means for removably securing the core assembly in the large channel opening.
Claim 2
Dependent Claim
170 words
In a twin-belt continuous metal casting machine having casting belts revolving around two belt supporting carriages for defining a casting region between the belts, and wherein each of the carriages has a frame with main rolls located at opposite ends of the carriage for revolving the casting belt around the carriage, the invention comprising: a removable core assembly for insertion into each belt carriage including a plurality of coolant applicators having coolant conduits extending transversely across the core assembly for applying liquid coolant to a casting belt and a plurality of finned back-up rollers extending transversely for supporting and guiding the casting belt adjacent to the casting region, the frames of each of the carriages defining a large channel opening on the side of the carriage facing toward the casting region for receiving the core assembly inserted therein, means for removably connecting each of said coolant conduits to a supply of liquid coolant in the casting machine, and means for removably securing the core assembly in the large channel opening.
Claim 3
Dependent Claim
30 words
In a twin-belt continuous casting machine, the invention as claimed in claim 1, in which: said coolant conduits are rigid and form transverse stiffening beams in the removable core assembly.
Claim 4
Dependent Claim
79 words
In a twin-belt continuous metal casting machine, the invention as claimed in claim 2, in which: longitudinal stringers and side rails are included in the removable core assembly secured to said coolant conduits, and said finned back-up rollers are divided into segments mounted in end to end relationship in the removable core assembly to sPan the width of the core assembly, the respective ends of the segments of the backup rollers being mounted on said stringers and side rails.
Claim 5
Dependent Claim
63 words
In a twin-belt continous metal casting machine, the invention as claimed in claim 1, in which: each of the removable core assemblies includes a base plate, and said means for removably securing the core assembly in the large channel opening includes a pair of clamp members extending longitudinally of the belt carriage, said clamp members engaging the edge portions of said base plate.
Claim 6
Dependent Claim
52 words
In a twin-belt continuous metal casting machine, the invention as claimed in claim 1, in which: the large channel opening defined by the frame of the belt carriage extends the major part of the length of the respective belt carriage between the main rolls, and the removable core assembly fills this opening.
Claim 7
Dependent Claim
36 words
In a twin-belt continuous metal casting machine, the invention as claimed in claim 5, in which: each of the removable core assemblies is modular and can fit into the large channel opening of either belt carriage.
