Description

COOLING DEVICE FOR CONTINUOUS CASTING LINE}

The present invention relates to a cooling device for extending the life of a performance equipment to install a cooling device in the cutting device of the performance equipment to extend the life of the performance equipment.

In general, a continuous casting machine is a facility for producing slabs of a constant size by receiving a molten steel produced in a steelmaking furnace and transferred to a ladle in a tundish and then supplying it to a mold for continuous casting.

The continuous casting machine includes a ladle for storing molten steel, a continuous casting machine mold for cooling the tundish and the molten steel exiting from the tundish into a casting having a predetermined shape, and a casting formed in the mold connected to the mold. It includes a plurality of pinch rolls to move.

In other words, the molten steel tapping out of the ladle and the tundish is formed of a slab or a casting having a predetermined width and thickness in the mold and transferred through the pinch roll.

An object of the present invention is to provide a cooling device for extending the life of the performance equipment to extend the life by cooling the hydraulic motor of the performance equipment.

Life extension cooling device of the performance equipment according to the present invention for achieving the above object is installed on the outer side of the cutting device for cutting the workpiece discharged from the pinch roll spraying device for spraying the coolant; And a cooling water supply device connected to the injector and supplying cooling water.

In addition, the injection device, the injection pipe is connected to the cooling water supply device; And a plurality of injection nozzles formed in the injection pipe.

According to the cooling device for extending the life of the playing equipment according to the present invention configured as described above by reducing the temperature of the cutting device to the coolant to increase the hydraulic motor life of the cutting device to match the life of the cutting device and the hydraulic motor replacement. This has the advantage of reducing costs.

2 is a block diagram showing a cutting device and an injection device according to an embodiment of the present invention,
Figure 3 is an enlarged view showing the injection device according to an embodiment of the present invention,
4 is a plan view of a cutting device according to an embodiment of the present invention.

Hereinafter, with reference to the accompanying drawings, a cooling device for extending the life of a performance equipment according to a preferred embodiment of the present invention will be described in detail. In the present specification, different embodiments are given the same or similar reference numerals for the same or similar configurations, and the description is replaced with the first description.

Continuous casting is a casting method in which castings or steel ingots are continuously drawn while solidifying molten metal in a mold without a bottom. Continuous casting is used to manufacture simple products such as squares, rectangles, circles, and other simple cross-sections, and slab, bloom and billets, which are mainly for rolling.

The type of continuous casting machine is classified into vertical type, vertical bending type, vertical axis difference bending type, curved type and horizontal type. 1 illustrates a curved shape.

1 is an overall configuration diagram of a continuous casting plant according to the present invention, Figure 2 is a block diagram showing a cutting device and a spraying device.

1 and 2, the injection device 30 is installed on one side of the outer side of the cutting device 20 for cutting the workpiece discharged from the pinch roll 10 and spraying the coolant, and the injection device It is connected to 30 includes a cooling water supply device 40 for supplying cooling water.

The injection device 30, a plurality of injection nozzles 32 are formed in a row to inject water to the outer surface of the cutting device (20).

The injection device 30 may be provided along a plurality of the outer periphery of the cutting device (20).

That is, the present invention will be described in more detail as follows.

Referring to FIGS. 1 and 2, the cooling water is sprayed on the outer surface of the cutting device 20 for cutting the solidified shell processed in the pinch roll 10 for processing the solidified shell 3 formed by solidifying molten steel. It is composed of an injection device 30 and a cooling water supply device 40 for supplying cooling water to the injection device (30).

The pinch roll 10 is to process the solidified shell (3) in a shape that is set when the molten steel discharged from the mold (1) flows through the curved roller (2), a plurality of pinch rolls 10 are the same Installed in position, it will eject multiple workpieces at once.

The cutting device 20 is operated by a hydraulic motor, and the processed solidified shell discharged from the pinch roll 10 is cut into a predetermined length to be discharged.

Figure 3 is an enlarged view showing the injection device according to an embodiment of the present invention.

Referring to Figure 3, the injection device 30 is installed on the outside of the cutting device 20, the injection pipe 31 is connected to the cooling water supply device 40 and the injection pipe ( 31 is composed of injection nozzles 32 formed in large numbers.

The injection device 30 may be installed on the outside of the cutting device (20).

The cooling water supply device 40 is connected to the injection pipe 31 of the injection device 30 to supply the cooling water.

The method of extending the life of the performance equipment through the above configuration is to install the injection device 30 on the outer periphery of the cutting device 20, it is to connect the cooling water supply device 40 to the injection device (30).

Next, when the cooling water is injected into the injection pipe 31 of the injection device 30 through the cooling water supply device 40, the cooling water is injected through the injection nozzle 32 formed in the injection pipe 31, thereby cutting the cutting device ( 20) to cool the hydraulic motor.

This lowers the temperature of the hydraulic motor and extends the life of the hydraulic motor.

As such, by lowering the temperature of the cutting device 20 of the performance equipment with cooling water, the hydraulic motor life of the cutting device 20 is increased to match the life of the cutting device 20 with the life of the hydraulic motor, thereby reducing the replacement cost. There is this.

The present invention has been described with reference to the preferred embodiments, and those skilled in the art to which the present invention pertains to the detailed description of the present invention and other forms of embodiments within the essential technical scope of the present invention. Could be. Here, the essential technical scope of the present invention is shown in the claims, and all differences within the equivalent range will be construed as being included in the present invention.
