Plant and device for the transport of billets from a continuous casting plant or rolling mill by cross rake

The invention relates to a device for transporting billets from a continuous multi-strand caster or rolling mill, namely a device that receives the billets in an orderly and parallel manner from the roller table and takes off and places it on a collapsible platform, from where the billets are transported from a latch tug to the Exit to be towed.

The system according to the invention is equipped with rakes, the complete independence of each of the veins and accurate

Alignment of each billet with the neighboring billets allows and falling of billets onto the transfer device in addition to the resulting risk of the continuous conveyor system coming to a standstill. Lift up the billet and placing the billet on the transfer platform is controlled by an automatic pneumatic or hydraulic system causes. When a stick is lifted from the roller table level into the cross tractor platform, he lifts a foldable component, which then falls down again and closes the platform again; the stick is filed in precise order and ready for onward transport to the outlet.

It is well known that in modern, continuous, multi-core continuous casting plants, the funds for the billets are The cause of difficulties due to the interdependence of the veins. Such difficulties can lead to The system will come to a standstill if the arrival of the billet of the cores is not or cannot be synchronized. In Systems with non-dependent veins, in which the billets on the transfer platform are not raised, but rather lowered Since the platform is located there on the ground, it can happen that the sticks are poorly aligned are, so that the casting must be interrupted or the system must be shut down.

According to the invention, the device for transporting billets is from a continuous caster or rolling train provided by cross rake that each of the several rows of incoming billets is independent and the billets of any kind produced, even of different lengths, can reach the transverse transport area without opening Meeting obstacles or creating difficulties.

The drawing shows a schematic partial view of a device for implementing the new billet conveying system according to the invention. This device has as features a transfer platform B, which works transversely to the axis of the billets 1 and 2, which arrive from two independent roller tables I and II, each of which has a set of parallel arms 3 and 4. has, which are pivotally mounted at 3 'and 4' and can be pivoted by pneumatic or hydraulic servomotors, not shown, within an angle of almost 90 about the pivot pin. The swivel arms 3 and k are L-shaped at their free end in order to be able to accommodate the billets 1 and 2, and lift such billets onto the platform B with each swivel movement has put down, back unloaded and lies down horizontally to pick up the next stick.

As shown, this platform B has at least one foldable component 5 'which is articulated at 6 and can be pivoted between the horizontal position 5 and a raised position 5 '. This movable one Component will fall down again after passing through a billet due to its own weight is to restore the handover platform. The tractor working on the transfer platform contains a plurality of parallel pawls 8, which are moved back and forth in guides 9 and the stick from the arrival side Drag (on the right in the drawing) to the outlet side (on the left in the drawing) towards outlet 7. Every

Movement happens in a well-ordered and planned manner. From the outlet 7 the billets can then be transferred to a collecting platform or a cooling bed can be dragged, unloaded in troughs and transported further by crane or elevator.

Claims (1)

Expectations 1. Plant for the transport of billets from a continuous caster or rolling mill to the outlet, characterized in that it has at least one transfer platform (b), which is arranged laterally at the end of the roller table, and a plurality of parallel rake swivel arms ( 3 »^)» which are arranged at an angle or radially between the end of the roller table (i, II) and the beginning of the transfer platform (B) to lift the billets (i, 2) one by one and place them on the To raise the transfer platform and to deliver it there, as well as a rod tractor which is arranged above the transfer platform (B) and can be moved back and forth transversely and by means of a pawl (8 ) drags the stick (i, Z) to the outlet (7). 2. Plant according to claim 1, characterized in that the free end of the billet (1, 2) receiving or lifting swivel arms (3 »^) L-shape and thus a Has wing that the stick on the entire swing arc from lifting to placing on the transfer platform wearing. 3. Plant according to claim 1 and 2, characterized in that the rake swivel arm (3 »^) by a hydraulic or pneumatic regulation is controlled. k. Plant according to claim 1, characterized in that each of the continuous casting strands is completely independent with regard to the organs for billet conveyance. 309845/1004 5. Plant according to claim 1, characterized by an open transfer platform (b), which is used to promote the stick is used from bottom to top and then restored by the fall of the movable component (5) will. 6. Plant according to claim 1, characterized in that billets of any cross-sectional shape and length are transferred can be changed without the built-in system or its device needing to be changed. 3098 AB / 1 00Λ
