The present invention relates to a simple roofing system for preventing corrosion of a pickled steel sheet, and more particularly, to a rust generated inside a rinsing tank at a line stop time in a rinsing tank, which is inevitably generated in a continuous work process. ), And when the looper adjustment work occurs before and after the line stop time, the simple looping adjustment can be effectively and safely suppressed, thereby preventing the occurrence of rinsing rust, improving work efficiency and improving quality, and preventing safety accidents. A simple roofing system for preventing corrosion of pickled steel sheets.

In general, as shown in Figs. 1A and 1B, a production facility for pickled steel sheets made of hot rolled coils is a looper of strips at the entry and exit sides so as to facilitate continuous operation without stopping the line by a plurality of rolls. Skin Pass is equipped with a system (Looper System) and performs a skin pass for rolling while correcting the shape of the hot rolled coil. With the skin pass roll (6), the line is stopped and the rinsing rust is applied to the strip passing through the rinsing tank. In the pickling rolling process, the supplied coil is mounted on a pair of reel (1), and then the tail of the coil is cut two or three times with a cutter (4), Welder 5 is welded to the end of the pickling recoil, and then the first tension braid roll 17 and the second tension, which act as an entry looper system when the strip 16 enters after welding recognition punching is performed. Braid roll (18) Hit switch the skin pass roll is determined by the examiner using a mode of use by the operator to the ever weld line is stopped at the time passing through the skin pass roll 6.

Then, the skin pass roll 6 crosses (10 seconds), and the pickling action is carried out through the scale brake 5, the third tension braid roll 8, and the tension meter roll 9, in which the line moves to suppress the scale. The strip proceeds through the pickling tank 10 and the rinsing tank 11 to remove residual hydrochloric acid using water, and enters the exit looper system 13 through the fourth tension braid roll 19. .

In the above process, the strip 16 (shown in FIG. 1B) can be stored and looped using the entrance looper system 12 and the exit looper system 13 installed at the front and the rear, but the skin pass roll 6 The stop of the line due to the cross and open of the skin pass roll 6 is inevitable when the strip shape is corrected, and the rinse rust (in the strip 16 across the pickling tank 10 and the rinsing tank 11). 14) (shown in FIG. 1B) is often not possible to proceed with normal operation, in particular, due to the occurrence of the rinsing rust 14, as shown in Figure 1b typically dozens of skin pass rolls on a daily basis The rinsing rust 14 generated each time by the repeated use of (6) is generated about 10 m in one working reference.

Therefore, in the strip straightening method using the skin pass roll 6, the line is cut at the time when the punching strip enters the skin pass roll 6 at the work side and the drive side of the welded portion, respectively. The pickling tank 10 and the rinsing tank 10 are stopped, while the skin pass roll 6 is stopped while being crossed (about 10 seconds) and opened and stopped (about 5 seconds) as shown in FIG. 1B. 11), the strip 16 proceeds in the direction of progress when the work is completed.

However, in the above operation, a rinsing rust 14 is generated in a substantial portion of the strip 16, and the rinsing rust 14 is generated about 100 m at a time, so that the rust 14 is generated. Cutting the part inevitably results in a low speed operation of the line, which leads to a decrease in productivity, thereby increasing the amount of work.

Therefore, as shown in FIG. 2 to solve the problem of the occurrence of the rust, the iron plate moving device and the up and down operation to prevent the hunting and looping phenomenon (sag, bending) of the strip 16 The hydraulic cylinder 22 is configured, and if an abnormality such as flow or deflection occurs while the strip 16 moves in the advancing direction, the operator judges the cab to operate the iron plate moving device and the hydraulic cylinder 22. As such, when the hydraulic cylinder 22 is operated, the roller 24 is raised upward in parallel with the strip 16 to prevent the looping and sagging of the strip.

However, since the above-described conventional technology must be operated by the driver directly in the cab, the oiling equipment 23 falls out and the speed of the strip is converted to the low speed or the high speed due to the working conditions of the empty space. When a sudden roofing is made by the strip 16, the strip 16 is flowed or the roofing is severe, and there is a problem that a plate overlap phenomenon occurs on the surface of the iron plate, and also there is a limit of the installation width, so that the stripping device, in particular, only one roller There is a problem that it is almost impossible to support 16.

The present invention has been made to improve the conventional problems as described above, when a simple roofing system can be effectively controlled when solving the line stop state in the rinsing tank, the simple roofing system is automatically operated to cause defects in the rinsing rust. It is an object of the present invention to provide a simple roofing system for preventing corrosion of pickled steel sheet, which can improve the work efficiency and quality while suppressing the pressure.

The simple looping motor unit is controlled by the encoder 230, and the information of the strip 16 (shown in FIG. 1B) received from the exit PLC 125 shown in FIG. 8 and the information per minute speed of the strip 16 are shown. Is transmitted to the looping control PLC and the motor controller 127, the looping control PLC and the motor controller 127 control the encoder 230, and the geared motor 229 is controlled by the signal of the encoder 230. It is operated by the action of the rack gear and pinion.

The simple roofing system for preventing corrosion of a pickled steel sheet according to the present invention having the above function will be described in more detail with reference to the drawings shown in FIG. 8.

As shown in FIG. 1A, first, when the pickling recoil work progress is completed, the coil information is checked at the entry terminal Host to transfer the coil to the entry coil car, and then mounted on the fair-off reel 1 to press roll 2. ) And pinch roll (3). Subsequently, the tail portion of the strip 16 (shown in FIG. 1B) is cut to weld the pickle recoil advanced coil tail portion and the entry roll tail portion.

Subsequently, when the welding of the tail part is completed, a welding part recognition punching operation is performed on the welding part, and the strip 16 passes through the first tension braid roll 17 and the second tension braid roll 18. At the same time, while detecting the punched weld in the welding sensor (not shown), the strip information is received and retrieved from the exit and entrance PLCs 125 and 126, and as shown in FIG. 7, the encoder 230 is a rack gear. After the transfer distance (R1) of the detection value is derived and transmitted to the looping control PLC and the motor controller 127, the looping control PLC and the motor controller 127 display the detected value through the line dedicated monitor 124. Let's go.

Then, while the line speed drops from the normal (110mpm) to 40mpm, the speed of the fourth tension braid roll 19 drops to 20mpm and the roofing of the strip proceeds.

Next, after the encoder 230 detects the looping elongation, the encoder 230 transmits the detected value to the looping control PLC and the motor controller 127, and the looping control PLC and the motor controller 127 output the PLC numerical control movement signal. The geared motor 229 is operated.                     

Accordingly, as shown in FIG. 3, the roofing system according to the present invention is operated upward to serve to temporarily store the strip 16.

As the strip 16 is stored as described above, the weld portion of the strip passes through the skin pass roll 6, and the fourth tension braid roll 19 when the strip 16 stops at the center line of the skin pass roll 6. The speed is lowered to 7mpm. As the fourth tension braid roll is lowered and the gearing motor 229 is rotated in reverse, the roofing system according to the present invention is lowered, and the storage amount of the strip 16 is reduced due to the movement of the strip 16. The line proceeds normally.
