Description

Strip gutter of annealing furnace

The present invention, in the continuous annealing line during the cold rolling process, removes the defective part of the strip at the time of breaking the strip inside the high temperature annealing furnace and performs the mailing operation by the chain. The present invention relates to a strip mailing device of an annealing furnace that prevents a safety accident of an operator by easily handling a high-temperature chain passing through a furnace by performing a mailing operation of a strip.

In general known annealing operations, in order to soften the steel and adjust the crystal structure or to remove internal stresses, heating is performed at a suitable temperature and then gradually cooled, and the defective parts of the broken strips are removed during the annealing operation. The chain is then hooked up to the strip to carry out the work of mailing between the rolls.

As shown in FIG. 1, a winch operation for a plate pass of a conventional strip associated with this technique is performed by inserting a chain 51 drawn out after a mailing operation in an annealing furnace into the inside of the truck 53. Cooling water is deposited on the inside of the cooling tank 52, the drum 54 is installed on one side of the cooling tank 53, a plurality of rings 55 in the interior of the cooling tank 52 integrally It consists of the components that are installed.

In the above-described strip winch operation of the strip, the operator catches the chain 51 drawn out of the annealing furnace so as to cross the ring 55 of the cooling tank 52 in which the coolant is loaded, thereby increasing the cooling effect. The 51 is rotatably supported by the drum 54 installed inside the truck 53 so that the chain 51 can be easily pulled out.

However, in the mail order winch operation as described above, there is a risk of burns due to the operator having to position the hot chain 51 by manual labor to perform the mail order operation, and the ring 55 installed inside the cooling tank 52. The working time for connecting the chain 51 to the increase in time, there is a problem that requires a large number of working personnel, such as the operator must winch the chain 51.

The present invention is devised to solve the above problems, the object of which is to prevent the deformation of the roll due to the hot chain contact by the cooling air flowing into the inside of the chain drum, and the chain wound on the lower roll The present invention provides a strip sheeting device for annealing furnace that prevents a safety accident of an operator because it is unnecessary for a person to winch the chain by being pressed by a press roll in contact with the sheet.

In order to achieve the above object, the present invention, the discharge chute is coupled to the traction box installed to be movable on one side of the annealing furnace, the air hose and the motor is connected to both ends of the inner side of the traction box, respectively, the chain A drum is installed facing each other, and the inner circumference of the chain drum is recessed to form recesses, and a plurality of air grooves and protrusions are integrally formed on the upper side thereof, and a blotting roll having integrally formed protrusions integrally to the recesses is formed. A cooling pipe is fixed to a cylinder having one end coupled to a frame at an upper side of the towing box, and a plurality of protrusions are integrally formed at the periphery of the protrusion of the press-roll roll, and a plurality of air grooves are formed inside the opposite side of the chain drum. By providing a strip plate of the annealing furnace to be installed.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a schematic diagram showing the strip pulled state of the mail order chain according to the present invention, Figure 3 is a schematic view showing the main portion of the chain inserted into the paper press roll and the chain drum according to the present invention, Figure 4 is As the operation state diagram showing the traction state of the chain according to the present invention, by installing a traction box (1) to the chain 3 is pulled on one side of the annealing furnace and the discharge chute 2 is coupled to one side, the traction On both sides of the inner side of the box 1, a chain drum 6 having air hoses 4 and a motor 5 connected to both ends thereof is opposed to each other, and the inner circumference of the chain drum 6 is recessed so as to be recessed. ) Is formed and a plurality of air grooves 8 and the projections 9 are integrally formed on the upper side thereof.

In addition, a cylinder 13 having one end coupled to the frame 12 on the upper side of the tow box 1 has a press roll 11 having a protrusion 10 integrally formed on an upper side thereof so as to be in close contact with the recess 7. It is fixed to, a plurality of protrusions (9a) is formed integrally on the periphery of the protrusion (10) of the press paper roll (11).

Subsequently, a cooling pipe 14 having a plurality of air grooves 8a formed between the chain drums 6 installed to face the inner side of the tow box 1 is installed, and one end of the motor 5 is provided. It is made of a configuration that the air hose 4 is connected to the other end so that the chain drum (6) to be connected is rotatable by the rotary joint (15).

Referring to the operation of the present invention made of such a configuration as follows.

As shown in Figs. 2 to 4, by the operation of the cylinder 13 in a state in which the chain 3 introduced into the inner side of the annealing furnace is wound around the outer periphery of the chain drum 6 in order to perform a mailing operation. The down pressure roller 11 is operated downward so that the chain drum 6 and the pressure roller 11 are brought into close contact with each other. Then, the chain 3 is passed through the cooling pipe 14, and the cooling pipe 14 is continued. The chain 3 passed through 14 is wound around the chain drum 6 on the opposite side to lower the blotting roll 11 to fix the chain 4.

In addition, the chain (3) by the chain drum (6) and the chain (3) fixed by the blotting roll (11) which are respectively installed on both sides of the opposing side are rotated when the motor (5) is driven. The towing is moved to one side and the mailing operation is performed, wherein the chain 4 is dropped into the recovery box 16 through the discharge chute 2 on one side of the tow box 1 to be automatically recovered.

Subsequently, the chain 4 is cooled by an operation in which cooling air flows inside the cooling pipe 14 during the mailing operation and is discharged through the air groove 8a to prevent injury to the worker due to high temperature, and the joint (15) The deformation and premature wear of the chain drum 6 are prevented by the cooling air flowing into the chain drum 6 through the connected air hose 4, thereby improving the reliability of the chain 4 towing operation. .

Further, protrusions 9 and 9a are integrally formed on the upper side surfaces of the chain drum 6 and the press roller 11 to prevent sliding of the chain 4 so that the chain 3 is always pulled at a constant speed. The plate (3) which is directed to the mailing operation, and the protrusions (10) formed on the blotting roll (11) to be in close contact with the concave portion (7) formed in the chain drum (6) is inserted into the inside Departures are to be prevented.

According to the strip mailing device of the annealing furnace of the present invention as described above, the mailing work with a minimum number of people by the chain drum and the push-up roll installed to be in contact with each other, by the cooling air flowing into the inside of the chain drum It prevents roll deformation due to high temperature chain contact, and the chain wound on the lower roll is pushed by the pressing roll in contact with the upper part, so that no additional personnel for chain towing is needed. The practical effect of preventing is obtained.
