Abstract

PURPOSE:To provide a titled device which enables inline treatment of a short- sized crop and lessens manpower by the constitution in which the cut billet and short-sized crop are quickly moved by utilizing a self-traveling transfer type table and are transferred to a conveying table. CONSTITUTION:A travel table 7 provided with a lifting table 5 which is risen by a lifting cylinder 6 and supports a billet 3 under cutting is moved by means of a driving device 13 and a driving wheel 9 between front and rear tables 4 and 11 of a cutting machine in synchronization with the billet 3 with a treating device for billet which cuts the continuous casting billet 3 with a cutting torch 1. The table 7 is quickly moved upon ending of cutting to move the billet 3 or crop to the table 11 then a driving device 16 for rollers is actuated to eject the billet or crop. The short-sized crop is further pushed out in the direction perpendicular to the advancing direction of the billet 3 by a pusher 14 and is transferred onto the skid table 15 alongside the line. On the other hand the table 7 is reset to the home position by lowering the table 5 by means of the cylinder 6.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a slab processing device attached to a cutting torch that continuously cuts slabs in-line.

Conventionally, the roller provided on the rear surface of the cutting torch is
In order to prevent molten slag from adhering to the roller when the torch 1 approaches, a darting roller a (Fig. 1) that lowers the rollers one after another or a travel roller b (second Figure) was common.

However, the shortest length of a slab that can be transferred using these conventional methods is limited to about 2 m, but with the latest equipment, the cropping at the tip and rear end of the slab, and the cut off part at the joint in continuous casting, is less than 1 m. Therefore, in the conventional method, this crop could not be processed in-line, so it was taken out of the machine uncut and cut off-line.

This requires an extra work to cut the slabs and crops, and this has to be done manually, which has the disadvantage of increasing operating costs. In addition, in the case of a travel roller, if the burr attached to the cut end surface of the slab becomes large, it becomes difficult to return to the original position.

The present invention was proposed in order to solve the above-mentioned conventional drawbacks, and is a slab processing device that can carry out a crop of about 1 m or a joint part of continuous casting even if it is cut from a slab of a specified length. When cutting slabs of specified length and when cutting crops of about 1 m,
By using the movable table installed at the rear of the cutting machine, and by making the table itself and rollers self-propelled, it is possible to transfer slabs or short crops onto the transfer table, and the crops can be transferred immediately to the cross conveyor. It is an object of the present invention to provide a slab processing device which is characterized by having a mechanism that allows the slab to be carried out from the table to the outside of the production line by using the above-mentioned tools, etc., and which is characterized by saving labor.

Embodiments of the present invention will be described below with reference to the drawings. FIGS. 3 and 4 show embodiments of the present invention, and in the case of the drawings, the drawings show the steps immediately before cutting for conveying a slab of a predetermined length during casting. It shows the condition. In the figure, 1 is a cutting torch, 2 is a torch 1
3 is a slab, 4 is a cutting machine front table, 5 is a lifting table, 6 is a lifting cylinder, 7 is a travel table, 8 is a guide rail for the travel table, 9 is a drive wheel, 10 is a clamp, 11 is a rear table of the cutting machine, 12 is a cutting command transmitter, 13 is a travel table drive device, 14 is a pusher, 15 is a skid table, and 16 is a roller drive device.

Now, in order for the cutting torch 1 to cut the slab being cast, a travel table 7 is provided between the front table 4 and the rear table 11 of the cutting machine, and moves in synchronization with the slab.
It is designed to be able to move forward and backward via a drive device 13 and drive wheels 9. Further, the elevating table 5 is installed on a travel table, and is moved up and down by an elevating cylinder 6.

The rollers of the lifting table are provided with a drive device 16 so that the slab can be transported. Also, there is a 1 on the entrance side of the rear table.
A pusher 14 and a skin tip 15 are provided for removing clocks as short as m from the line.

Next, to explain the operation, when the tip of the slab 3 reaches the cutting command transmitter 12 from the state shown in FIGS. 3 and 4, the torch 1
starts cutting while moving in synchronization with the slab 3. The travel table 7 is moved in synchronization with the slab by a clamp of 1°. When cutting is completed, the travel table 7 carries the slab with the cast slab placed thereon to the rear table by the driving device 13, and drives the rollers to carry out the slab.

When the slab is carried out, the transfer table 7 reverses the driving device 13 and returns to its original position. At this time, the lifting table 5 lowers the lifting cylinder 6 to provide a gap between the lifting cylinder 6 and the slab, so that even if there is debris such as cutting slag on the cut surface of the slab, there is no problem with the return.

Next, when processing a short crop, when a cutting command is issued from the state shown in FIG. 5, the lifting table 5 is raised,
At the same time that the slab and the lifting table are moved in synchronism by the clamp 10, the driving device 13 is also driven to apply a tensile force between the slab and the clamp 10 to the extent that no slipping occurs. When the crop is cut off, the crop is transferred with 1° placed on this table, and when it reaches the stroke end (Fig. 6), the roller table is driven, the crop is transferred to the rear table of the cutting machine, and the pusher 14 moves the crop to the side of the line. Transfer to the skin to the top 15.

Since the present invention is configured as explained in detail above,
It is possible to separate short crops of about 1 m or joints between continuous castings from slabs, and transport and store the slabs and crops separately. In addition, after cutting off a short crop, it has a drive device that moves the transfer cart back and forth and a drive device that drives the rollers when transporting it to the rear table and sending out the crop further from the stroke end. , cutting, and transport operations can be carried out smoothly.

Since the transfer cart is equipped with a lifting table, it is possible to prevent interference even if there is a burr on the cut end surface when returning the slab or crop to its original position after being sent out.
