Abstract
Abstract A continuous casting method which includes solidifying a molten metal in a casting wheel and injecting a heat-conducting medium into the gap formed between the metal and the casting wheel as a result of the solidification of the metal. Casting apparatus is also disclosed and includes a casting wheel having a peripheral groove with a portion closed by an endless band to form a mold and injecting means for injecting a heat-conducting medium into the mold to fill the gap formed between the metal in the mold and the casting wheel when the metal shrinks during its solidification.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
76 words
In a process of casting molten metal the steps of feeding a molten metal into a mold formed by a peripheral groove in a rotating casting wheel and a continuous band closing a portion of the groove, cooling the mold until the said molten metal is partially solidified and shrunken due to the partial solidification, and placing a heat-conducting medium between the partially solidified metal and the mold, and continuing the cooling of the said mold.
Claim 2
Dependent Claim
76 words
In a process of casting molten metal the steps of feeding a molten metal into a mold formed by a peripheral groove in a rotating casting wheel and a continuous band closing a portion of the groove, cooling the mold until the said molten metal is partially solidified and shrunken due to the partial solidification, and placing a heat-conducting medium between the partially solidified metal and the mold, and continuing the cooling of the said mold.
Claim 3
Dependent Claim
31 words
The process according to claim 1 in which the placing of a heat-conducting medium is begun where a gap first begins to form between the partially solidified metal and the mold.
Claim 4
Dependent Claim
28 words
The process according to claim 2 in which the gap is completely filled by the heat-conducting medium, and is maintained full while the metal is within the mold.
Claim 5
Dependent Claim
31 words
The process according to claim 1 in which the step of placing a heat-conducting medium includes passing the said heat-conducting medium between the said continuous band and the said casting wheel.
Claim 6
Dependent Claim
71 words
Apparatus for casting a molten metal including a casting wheel having a peripheral groove, a continuous band to close a portion of the groove to form a closed mold, means to introduce molten metal into the closed mold, and means for cooling said mold to solidify the molten metal, and injecting means to fill the closed mold with a heat-conducting medium where the molten metal cools and shrinks from the mold.
Claim 7
Dependent Claim
71 words
Apparatus for casting a molten metal including a casting wheel having a peripheral groove, a continuous band to close a portion of the groove to form a closed mold, means to introduce molten metal into the closed mold, and means for cooling said mold to solidify the molten metal, and injecting means to fill the closed mold with a heat-conducting medium where the molten metal cools and shrinks from the mold.
Claim 8
Dependent Claim
22 words
Apparatus according to claim 5 in which said injecting means includes means to separate the said band from the said casting wheel.
Claim 9
Dependent Claim
18 words
Apparatus according to claim 6 in which said injecting means is selectively positionable along the said closed mold.
