Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for applying an identification mark to a cast slab that is continuously fed out by a continuous casting machine and gas-cut into a predetermined length, and a method used to carry out this identification mark application method. This invention relates to an identification symbol applying device.

The slabs delivered from the continuous casting machine (hereinafter referred to as continuous slabs) are cut into various lengths by a gas cutting machine that runs in synchronization with the continuous slabs during the delivery, and then each continuous slab is cut into various lengths. An identification symbol is applied to the strip and sent to the subsequent process, but in the conventional method of applying an identification symbol, the continuous slab after cutting is stopped once and the symbol is applied, and in this case, the application device is also connected to the gas cutting machine. The equipment is fixedly located at a considerable distance, the total length of the equipment including the gas cutter and application device is long, and the overall processing time is long, making it inefficient. 1st
To explain the conventional continuous slab cutting and symbol marking process with reference to the figure, a synchronous traveling type gas cutting machine 1 is installed near the downstream side of the final drawing roll of a continuous casting machine, and this gas cutting machine cuts and separates the cast slabs. The continuously cast piece 2 is conveyed as it is for a certain distance A and stops at the position of the identification mark applying device 3. After an identification symbol corresponding to each continuously cast piece is applied by the application device 3, the piece is transported to the next step again. In the example in Figure 1,
After the identification symbol has been applied, the continuously cast pieces 2' are lifted up by the overhead crane 4, loaded onto a freight car, etc., and transported, or loaded from the overhead crane into a heating furnace, or placed on a cooling floor. In this way, in the conventional process, the cut continuous slab must be stopped once before the identification symbol is applied, and the process of decelerating, stopping,
It takes time to run again, and the subsequent continuous slabs are continuously pulled out even while the identification symbol is being applied.
In Fig. 1, in addition to the section C for applying the identification symbol, a distance A between the continuous slab and the subsequent continuous slab is required, which caused the problem that the total length B from the final drawing roll of the continuous casting machine to the end of the conveying section becomes long. .

The present invention solves the above-mentioned conventional problems, reduces the overall length of continuous casting equipment, reduces equipment costs, and improves overall efficiency. The purpose is to provide

The method for applying an identification symbol according to the present invention is such that an identification symbol applying device provided on the downstream side of a synchronous traveling type continuous slab gas cutting machine is run in synchronization with the continuous slab, and before the gas cutting of the continuous slab is completed. An identification symbol is applied to the image.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is a schematic side view of a portion downstream from the final drawing roll of continuous casting equipment using the identification symbol applying device according to the present invention. A synchronized gas cutting machine 1 is disposed downstream of the final drawing roll, and a continuous slab identification symbol applying device 3' that runs in synchronization with the continuous slab 2 is disposed downstream of the gas cutting machine. It is located. The synchronized gas cutting machine 1 includes:
As shown in the front view of FIG. 3, a traveling bogie 5 runs on a running rail 7 via wheels 8, and a blowpipe bogie 6 equipped with a gas cutting head is attached to the traveling bogie 5 to carry out continuous slab casting. It is mounted so as to move in a direction perpendicular to the conveyance direction of No. 2. 9 is a traveling drive device for the trolley 5. Although not shown, this gas cutting machine 1 is equipped with a continuous cast piece gripping device for synchronized movement with the continuous cast piece, a continuous cast piece detection device, a valve stand for fluid control, and the like.

A synchronous running type continuous slab identification symbol applying device 3' according to an embodiment of the present invention runs the traveling rail 5 of the gas cutting machine in synchronization with the continuous slab 2, similarly to the gas cutting machine 1. It has a truck and an identification mark application head (both not shown) mounted on the truck, and is also equipped with a traveling drive device for synchronized running, a continuous slab gripping device, etc. In this case, the synchronous running continuous slab identification symbol applying device 3'
It is not necessary to place the gas cutter at a large distance from the gas cutter as in the conventional case, but it is placed as close as possible to the continuous cast piece 2 during gas cutting as shown in FIG. Second
In the figure, a synchronous traveling type gas cutting machine 1 is connected to a continuous slab 2.
During cutting, the synchronously running continuous slab identification symbol applying device 3'
While traveling in synchronization with the continuous cast piece 2, an identification symbol corresponding to the continuous cast piece 2 is applied. Note that this application work is completed before gas cutting is completed. After the application of the identification symbol and the gas cutting are completed and before the continuously cast slab 2 is conveyed downstream at high speed, the synchronized running of the gas cutting machine 1 and the identification symbol application device 3' is stopped, and the gas cutting machine is first moved upstream. Make it move to the standby position on the side. Subsequently, the identification symbol application device is also moved to a standby position on the upstream side. The continuous cast piece that has been applied and cut is lifted up by the overhead crane 4 at a predetermined position.

In the above embodiment, since the application and cutting are performed almost simultaneously, there is no need to take sections A and C in the conventional method shown in FIG. It suffices to have a length D that is significantly shorter than that. In addition, since the continuous cast slabs are decelerated, stopped, and transported at high speed, it is possible to omit operations and time such as acceleration, etc., which prevents the temperature of the high-temperature continuous cast slabs from decreasing. can also save fuel. Furthermore, by using the rails for running the gas cutting machine for running the identification symbol application device, the configuration around the running path can be simplified and equipment costs can be reduced.

In the above embodiment, a case has been described in which the traveling carts of the gas cutting machine and the identification symbol applying device are installed separately on a shared rail, but in another embodiment of the present invention, the traveling carts are shared, and the gas cutting machine 1 and the It is also possible to mechanically connect the identification mark applying device 3' so that both move simultaneously in the conveying direction of the continuous cast piece in synchronization with the continuous cast piece. In this case, the continuous slab gripping device, traveling drive device, etc. can also be shared.
It is possible to further reduce equipment costs, shorten the overall length of equipment, and eliminate the risk of collision between both parties.
