Abstract
Abstract In a continuous-casting machine the dummy bar storage apparatus comprises a frame movable into the path of a dummy bar and a rocker storage section pivoted at the rear, downstream end of said frame and adapted to receive thereon a dummy bar which has passed through a withdrawal roll unit for the cast strand. Hoisting means for lifting the frame is adapted to lift the rear end twice as much as the front end and includes means for independently lifting the front end. The hoisting means is thus operable for adjusting the angular position of the frame to the angular position of the dummy bar emerging from the withdrawal roll unit and also for lifting the front end of the frame for disconnecting the dummy bar from the cast strand.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
194 words
Dummy bar storage apparatus for a continuous casting machine wherein at the beginning of a casting run a dummy bar connected to the head end of the cast strand is withdrawn from the mold followed by the casting, and a frame is movable into the path of a dummy bar withdrawn from the mold, said frame being adapted to receive and support a dummy bar therein, said apparatus comprising a rocker support section carried on the frame and being pivoted near one end for tilting the other end into and out of the path of a dummy bar from the mold in one position of the frame for receiving a dummy bar thereon, and hoisting means for raising and lowering the frame including means for moving the rear, downstream end of the frame in the same direction but by a greater amount than the front, upstream end, said hoisting means also including independently operable means for additionally raising and lowering said front end for adjusting the angular position of the frame relative to a dummy bar and for raising said front end for disconnecting a dummy bar in the frame from a cast strand.
Claim 2
Dependent Claim
194 words
Dummy bar storage apparatus for a continuous casting machine wherein at the beginning of a casting run a dummy bar connected to the head end of the cast strand is withdrawn from the mold followed by the casting, and a frame is movable into the path of a dummy bar withdrawn from the mold, said frame being adapted to receive and support a dummy bar therein, said apparatus comprising a rocker support section carried on the frame and being pivoted near one end for tilting the other end into and out of the path of a dummy bar from the mold in one position of the frame for receiving a dummy bar thereon, and hoisting means for raising and lowering the frame including means for moving the rear, downstream end of the frame in the same direction but by a greater amount than the front, upstream end, said hoisting means also including independently operable means for additionally raising and lowering said front end for adjusting the angular position of the frame relative to a dummy bar and for raising said front end for disconnecting a dummy bar in the frame from a cast strand.
Claim 3
Dependent Claim
142 words
The storage apparatus of claim 1 in which said hoisting means includes a first cable connected for lifting the rear of the frame and a second cable connected for lifting the front of the frame, one end of each cable being connected to first means for moving both cables longitudinally to alternatively lift and lower the frame, said second cable passing around a pulley arranged in a manner such that the pulling of the cables by said first cable moving means causes the front end of the frame to be lifted less than the rear end, And the other end of the second cable being connected to second cable moving means for moving the second cable to alternatively lift and lower the front end of the frame independently of the lifting and lowering of the frame by the first cable moving means.
Claim 4
Dependent Claim
115 words
The apparatus of claim 2 in which said first cable has one end attached to said first cable moving means and passes over a pulley and then down with its other end attached to the frame, and in which said second cable has one end attached to said first cable moving means and passes successively over a pulley, down and around another pulley that is mounted on the frame, and then up and over still another pulley with its other end attached to said second cable moving means, whereby operation only of the first cable moving means causes the rear end of the frame to rise and lower twice as far as the front end.
Claim 5
Dependent Claim
48 words
The apparatus of claim 1 which includes power means carried on the frame and connected for lowering and raising said other end of the rocker support section respectively into and out of the path of a dummy bar from the mold in said one position of the frame.
Claim 6
Dependent Claim
92 words
The apparatus of claim 1 which includes a stop at the rear end thereof in position to be engaged by one end of a dummy bar received on the frame, and a roller at the front end of the frame in position for supporting the other end of said dummy bar when said one end of the dummy bar engages the stop, said support roller and said stop being mounted on the frame for the movement longitudinally thereof and being connected together for movement in the same direction at the same time.
Claim 7
Dependent Claim
40 words
The apparatus of claim 1 in which said frame is adapted to receive and support thereon in stacked relation a plurality of sections of a sectioned dummy bar of which the sections are adapted to be separated from each other.
