Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

The present invention relates to an apparatus for charging charged water and a melting furnace including the same, and more particularly, to an invention for preventing discharge of internal heat or toxic substances by adjusting the charging of charged matters by an electromagnet unit.

In the scouring process, scrap is used as a raw material in the melting furnace to dissolve and refine it as molten metal.

Conventionally, as a method for charging scrap into a melting furnace, there have been a method of charging through a charging bucket, a method of charging through a finger shaft, a method of charging by using a pusher, and a method of charging by using a conveyor.

In the charging method through the charging bucket, the charge is first put into the charging bucket, and then the charging bucket is moved to the top of the melting furnace by the crane. Then, the operation of the melting furnace is stopped and the roof of the melting furnace is opened. After opening the lower part of the charging bucket, the charge in the charging bucket is poured into the melting furnace, the charging bucket is lifted, the melting furnace loop is closed, and the melting operation is performed again.

However, since this method requires the loop to be opened for loading the charge, the dissolving operation is normally stopped for about 3 to 5 minutes at the time of charging once, and the dust and heat inside the melting furnace are released to the outside. Therefore, There is a problem that the electric power of 10 kWh is consumed and the environment in the factory deteriorates.

In the method using the finger shaft, a shaft furnace capable of storing and preheating the charge immediately above the melting furnace is provided, and the supporting shaft provided with a water-cooling device is tightly closed in a finger shape at the lower portion of the shaft to pass the exhaust gas of the melting furnace. After the water has been configured not to pass through the crane, the crane is used to charge the charge to the upper part of the shaft. When the charge is sufficiently collected and the preheating is performed, the finger is opened and the charge inside the shaft is poured into the melting furnace.

However, this method has a problem that the operation is stopped due to the problem that the finger is deformed due to the heat generated in the melting furnace or the cooling device is broken and water leaks because the finger has to support the heavy load by the shaft.

As shown in FIG. 1A, a conveyor C is provided to move the charge S, and one end of the conveyor C is located outside the melting furnace 200 'to charge the charge S And the other end is connected to a connecting car capable of moving to the melting furnace 200 ', and the end portion of the connecting car is installed so as to be able to reach the inside of the melting furnace 200'. The connecting car is connected to the conveyor C and the melting furnace 200 'when the container S is loaded and to the outside of the melting furnace 200' when the container S is not to be charged, so that it does not interfere with the tilting of the melting furnace 200 ' Install it.

When the charge S is charged into the upper part of the conveyor C by a crane or a bucket, the charge S is advanced toward the melting furnace 200 'by the operation of the conveyor C and is supplied to the melting furnace 200' When the charge S is not charged, the connecting car is separated from the melting furnace 200 '.

However, this method is complicated in the conveyor (C) facility required for transportation of the charge (S), so that the facility investment cost and the maintenance cost are high and the energy cost is high for carrying heavy objects such as the charge S.

Further, there is a problem that frequent failure occurs because the end portion of the connecting car which has entered the melting furnace 200 'is damaged by the internal heat of the melting furnace 200'.

As shown in FIG. 1B, a storage furnace for storing and preheating the charge S is installed on the side or upper side of the melting furnace 200 ', and the furnace 200' A pusher P having a stroke capable of pushing the charge S in the storage furnace toward the melting furnace 200 'and a hydraulic device for operating the pusher P is installed. First, the charge S is charged into the storage furnace by a crane or a bucket, and when a sufficient amount is collected and the preheating is performed, the pusher P is operated to push the charge S of the storage furnace toward the melting furnace 200 ' It is a method of charging water (S).

However, in this method, since the pusher P needs to push out the heavy charge S in a hot state, even if the pusher P of a special material such as a carbide is used, the shape is deformed or the operation is stopped due to the deformation, There is a problem that the operation of the equipment is low due to the problem that the water (S) is caught between the pushers (P), and the expensive lifter of the pusher (P) is short and the hydraulic equipment is installed.

Therefore, there has been a need to study a charging device and a melting furnace including the charging device for solving the above-mentioned problems of the prior art.

It is an object of the present invention to prevent the opening of a melting furnace for charging a charge and to prevent foreign substances such as heat and dust inside the melting furnace from being released to the outside and to prevent the device from being damaged by the heat inside the melting furnace A water injection device and a melting furnace including the same.

In addition, according to the present invention, charging is made by gravity charging and blocking due to the magnetic force of the electromagnet unit. Therefore, the electromagnet unit and the charge do not come into direct contact with each other and the equipment failure is small, There is also a low advantage.

In addition, since there is no need to move the melting furnace or move the cover to charge the charge S, the charge S can be continuously charged without interrupting the melting operation. Therefore, The time is not separately consumed, and the working time can be shortened.

In addition, according to the present invention, since charging is performed by gravity-charged charge S and blocking by magnetic force of the electromagnet unit 120, the electromagnet unit 120 and the charge S are not in direct contact with each other, , It is possible to lower the maintenance cost of the facility because the work stoppage due to failure does not occur.

Also, the device body 110 of the charge-on-water device 100 according to an embodiment of the present invention may be provided inclined with respect to the direction of gravity g.

That is, an apparatus including the electromagnet unit 120 is provided so that the input of the charge S such as scrap can be adjusted by using an electromagnetic force. To this end, A body 110, and an electromagnet unit 120.

Here, the device body 110 serves as the body of the charging device 100 to which the electromagnet unit 120 is coupled.

The apparatus body 110 may also serve as a reservoir for storing the charge S in order to charge the charge S into the melting furnace.

That is, due to the electromagnetic force generated by the electromagnet unit 120, the charges S are adhered to the inner surface of the apparatus body 110 to prevent blocking of the supply of the charges S, Can be performed.

Here, the electromagnet 121 is coupled to the outer surface of the device body 110, and may generate an electromagnetic force depending on whether the power input unit 122 is powered on.

Particularly, the electromagnet 121 is coupled to an outer surface adjacent to the discharge port 112, which is a lower end portion of the apparatus body, so that when the charging of the charge S is stopped due to generation of electromagnetic force, It is possible to secure the amount of the charge S temporarily stored in the inside.

That is, since the device body 110 is provided close to the horizontal direction in the direction of gravity g, it is highly affected by gravity. Therefore, in order to stop the charging of the charge S by the electromagnetic force, The electromagnetic force of the electromagnet 121 is concentrated.

In addition, since the apparatus body 110 is provided close to the horizontal direction in the gravitational direction g, it is not greatly affected by gravity. Therefore, in order to precisely adjust the charging of the charge S by the electromagnetic force And a plurality of electromagnets 121 are provided in the longitudinal direction of the outer surface of the apparatus body 110.

[

That is, the cooling unit 140 protects the apparatus body 110 and the electromagnet unit 120 in a high-temperature environment by cooling them, thereby preventing a failure of the charging device 100.

Particularly, the performance deteriorates due to the high temperature environment inside the NOBDY 200, which is a portion adjacent to the electromagnet unit 120 where the attracting force by the electromagnetic force decreases as the temperature is higher.
