Abstract
Abstract An apparatus for feeding a short dummy bar from the path of travel of a casting into the region of the casting mold for introducing the dummy bar through the casting mold into a successive at least partially curved roller apron or strand guide. The apparatus of this development comprises a cartridge or cassette which can be located in a position for introduction of the dummy bar into the path of travel of the casting and a transport mechanism for the dummy bar. The cartridge provided with stop means and co-operating with the transport mechanism is mounted to be pivotal, the pivot axis of the cartridge being arranged at the path of travel of the casting or at the direct neighborhood thereof. In the pivoted position of the cartridge, the stop means exhibits a spacing from the path of travel of the casting which is greater than one half of the thickness of the cast casting.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
228 words
An apparatus for feeding a dummy bar from the path of travel of a casting of a continuous casting installation to the region of a continuous casting mold for introducing the dummy bar through the casting mold into a successively arranged at least partially curved roller apron, comprising the combination of: a transport mechanism for receiving and supporting the dummy bar for movement to the continuous casting mold, a cartridge located at the region of the casting path of travel for receiving the dummy bar, said cartridge having stop means, said cartridge cooperating with said transport mechanism, means for pivotably mounting said cartridge about a pivot axis for pivoting the cartridge and the therein received dummy bar the pivot axis of said cartridge being arranged at least at the direct neighborhood of the casting path of travel, said stop means in the pivoted position of said cartridge possessing a spacing from the casting path of travel which is greater than one-half of the thickness of the cast casting, a casting platform at which there is arranged a continuous casting mold, guide track means for said transport mechanism arranged essentially beneath said casting platform and extending from the location of pivotal movement of the cartridge to the region of the continuous casting mold for transport of the transport mechanism and dummy bar carried thereby to the continuous casting mold.
Claim 2
Independent Claim
228 words
An apparatus for feeding a dummy bar from the path of travel of a casting of a continuous casting installation to the region of a continuous casting mold for introducing the dummy bar through the casting mold into a successively arranged at least partially curved roller apron, comprising the combination of: a transport mechanism for receiving and supporting the dummy bar for movement to the continuous casting mold, a cartridge located at the region of the casting path of travel for receiving the dummy bar, said cartridge having stop means, said cartridge cooperating with said transport mechanism, means for pivotably mounting said cartridge about a pivot axis for pivoting the cartridge and the therein received dummy bar the pivot axis of said cartridge being arranged at least at the direct neighborhood of the casting path of travel, said stop means in the pivoted position of said cartridge possessing a spacing from the casting path of travel which is greater than one-half of the thickness of the cast casting, a casting platform at which there is arranged a continuous casting mold, guide track means for said transport mechanism arranged essentially beneath said casting platform and extending from the location of pivotal movement of the cartridge to the region of the continuous casting mold for transport of the transport mechanism and dummy bar carried thereby to the continuous casting mold.
Claim 3
Dependent Claim
48 words
The apparatus as defined in claim 1, further including support rolls for the casting, and wherein the pivot axis of the cartridge is located at the casting path of travel in a plane extending through a central axis of the casting and essentially parallel to the support rolls.
Claim 4
Dependent Claim
51 words
The apparatus as defined in claim 1, further including support rolls for the casting, and wherein the pivot axis of the cartridge is located near the casting path of travel to one side of a plane extending through a central axis of the casting and essentially parallel to the support rolls.
Claim 5
Dependent Claim
31 words
The apparatus as defined in claim 1, wherein said pivotal mounting means for the cartridge comprises a support and pivot shaft means, said pivot shaft means being detachable from the support.
Claim 6
Dependent Claim
20 words
The apparatus as defined in claim 1, further including drive means provided for said cartridge for conveying the dummy bar.
Claim 7
Dependent Claim
21 words
The apparatus as defined in claim 1, further including drive means provided for said transport mechanism for conveying the dummy bar.
Claim 8
Dependent Claim
30 words
The apparatus as defined in claim 1, wherein the transport mechanism serves to selectively receive either only the dummy bar in its pivoted position or in conjunction with the cartridge.
Claim 9
Independent Claim
178 words
An apparatus for feeding a dummy bar from the path of travel of a casting of a continuous casting installation to the region of a continuous casting mold for introducing the dummy bar through the casting mold into a successively arranged at least partially curved roller apron, comprising the combination of: a transport mechanism for physically receiving and supporting the dummy bar, a cartridge located at the region of the casting path of travel for receiving the dummy bar, said cartridge having stop means, said cartridge cooperating with said transport mechanism, means for pivotably mounting said cartridge about a pivot axis, for pivoting the cartridge and the dummy bar oUt of the path of travel of the strand while simultaneously disconnecting the dummy bar from the casting, the pivot axis of said cartridge being arranged at least at the direct neighborhood of the casting path of travel, said stop means in the pivoted position of said cartridge possessing a spacing from the casting path of travel which is greater than one-half of the thickness of the cast casting.
Claim 10
Independent Claim
178 words
