Abstract: A flame cutting machine for subdividing a steel strand or the like is constructed to be movable on rails on both sides of a roller table supporting the strand with a measuring roller for determining the linear measurement of the strand; the measuring roller is tilted on a lever affixed to the machine carriage and is unilaterally open with its axis being in a vertical disposition.

Abstract: A flame cutting machine for subdividing continuously prepared poured casting strands or the like includes an essentially closed suction head in the cutting zone which is mounted movable together with the flame cutting machine for removal of smoke gases, slag and the like produced during the cutting process.

Abstract: A flame-cutting machine for cutting a continuously cast rod includes a cutting torch attached to the machine for cutting the rod, a pair of clamping levers pivoted on the machine for clamping the rod, and a height-adjusting device which has a variable spacing from the rod; the cutting torch and the clamping levers are coupled to the height-adjusting device.

Abstract: In a continuous ingot casting installation, a table of ingot support rollers is arranged in the horizontal cutting zone. This table is arranged between an upstream and a downstream set of ingot support rollers and is reciprocably displaceable therebetween in the direction of the path of movement of the continuously cast ingot and parallel to that of the displacement of a cutting machine. The table is displaced automatically in a direction opposite to that of the cutting machine each time the oxygen torch of the machine approaches one of the rollers of the table and returned to its initial position. In this way, billets are cut from the cast ingot.

Abstract: A torch cutoff table and arrangement is provided for the cutting of steel product and the like. The cutoff table arrangement is employed with a torch which is movable in a first direction parallel to the direction of movement of the product across the table and in a second direction to effect a cutting of the product perpendicular to the direction of movement of the product across the cutoff table. The cutoff table arrangement provides for the support of the product as it is moved across the table without interference with the torch as the latter is moved in the two directions simultaneously.

Abstract: A cut-off device for a horizontally moving continuous casting includes a carriage assembly carrying a cut-off torch mechanism and a clamping mechanism. The assembly is mounted for reciprocable movement on a rod-like track which is open-ended to permit fast removal of the assembly for repairs. When the assembly is clamped to the moving casting, it is carried along therewith while the torch cuts through the casting to form billets of desired length. The track is floatingly mounted to permit deviation from the vertical by the casting without adversely affecting the cutting operation. The carriage assembly is tiltable on the track to permit horizontal deviation of the clamped casting. The torch is operated by a cam having a drop-off portion which quickly returns the torch to starting position. Upon release of the clamping mechanism, a damped counter-weight automatically returns the carriage assembly to its initial position on the track.

Abstract: The specification describes a thermal cutting machine for cutting up a continuously cast ingot during operation of a continuous casting plant, comprising a clamping means for entrainment of the thermal cutting machine with movement of the continuously cast ingot. A drive moves the thermal cutting machine along the continuously cast ingot and a cutting burner can be adjusted transversely with respect to the continuously cast ingot and can be driven. The thermal cutting machine is substantially enclosed by a cooling shroud, which only has a few passages for shafts, more particulary of support wheels and furthermore for a drive shaft of the cutting burner holder and for an actuating linkage of the clamping means.

Abstract: An apparatus for cutting a steel strand located in a support apron or support guide arrangement of a continuous casting installation by means of a cutting torch device. The cutting torch device, displaceable transversely with respect to the direction of travel of the strand, is arranged upon a support member of a change mechanism for elements of the support guide arrangement and can be displaced by means of this support member to desired locations of the support guide arrangement.

Abstract: Methods and apparatus are provided for protecting the supporting rolls of continuously moving freshly cast heavy metal strands (e.g., continuously cast billets and slabs), so that the rolls are not damaged by cutting torches while the strands being supported are being worked upon by those torches. This is achieved by sequentially pivoting individual ones of the supporting rolls out of the support path only momentarily as the cutting torch passes in the vicinity thereof, while continuously rotating the retracted support roll, and returning the roll to normal position after the torch has passed. Pivoting movement of a support roll, either in the retracting or return direction is caused to take place during the moments of highest exposure of the roll to flying slag from the torch in order to minimize the time of such exposure. This pivoting sequence of individual rolls takes place while still maintaining proper support of the strand by means of adjacent, operative support rolls.

Abstract: A method and apparatus for cutting short-length segments from a continuously-formed casting as it travels from the casting apparatus. The apparatus embodies conventional torches and carriages which are coupled together to perform two or more cutting operations simultaneously. The invention has particular utility for cutting segments which are too short to permit a single carriage to cut the casting and return to its starting position in time for the next cut.

Abstract: Extending downwardly from a guide rod above the rear end of a cutting table that supports a continuously cast metal strand as it travels forward over the table are a torch arm and a feeler arm, the upper ends of which are slidably and rotatably mounted on the rod to permit their lower ends to be swung transversely of the table independently of each other. A cutting torch secured to the torch arm is directed downwardly from it, and the feeler arm extends below the torch for engaging one side of a metal strand on the table. The feeler arm carries means for engaging the torch arm to position the lower end of the torch over the upper edge of the same side of a strand that the feeler arm is engaging. Located forward of the guide rod is a stop for engagement by the leading end of the strand for movement forward with it.
