Description

Recoiler device {RE-COILER}

The present invention relates to a recoiler device, and more particularly, to increase work efficiency by providing a washing unit to be selectively installed in a process line according to process needs, and to inject high-pressure steam water through a high-pressure injection device onto the surface of a coil. It relates to a recoiler device capable of efficiently removing oil on the coil, oxide flakes and some contamination through impinging on the coil.

After being rolled to a certain thickness by the cold rolling device, according to the product's demand, the strip steel will be transferred to the process after some other treatment, for example, the hot-dip galvanized product needs to be transferred to the continuous galvanizing device. The electrogalvanized product needs to be transferred to the continuous electrogalvanizing machine after continuous annealing, and the general cold-rolled product is subjected to a continuous annealing process or a batch annealing process to form a cold-rolled product.

In the case of strip steel coating processes such as continuous hot dip galvanizing or electrogalvanizing processes, the surface condition and cleanliness of the strip are essential conditions to ensure the quality of the continuous annealing coating. However, during steel rolling, there is a problem in that it is difficult to prevent various foreign substances such as drag in rolling oil, residual iron powder from cold rolling, accumulated dust, welding slag produced from head welding, and the like from remaining on the surface of the steel sheet.

Consequently, the strip must be cleaned to completely remove oil contamination on the surface prior to subsequent annealing. Otherwise, various oils remaining on the surface may form carbonaceous stains during annealing, contaminate the atmosphere inside the furnace, affect the effect of decarburization, and even cause recarburization. In addition, oil contamination can change the quality of the strip surface and induce nodules on the bottom roller, resulting in defects such as scratches on the strip surface.

In this regard, a cleaning process is provided to the continuous coating device prior to annealing, and this process is also called a degreasing process, since it is necessary to remove various foreign substances remaining on the strip surface.

It can play a role to be located in. Hereinafter, for unification of terms, the deformed strip to be given initial flatness by the 3 bending rolls 105 will also be referred to as a 'coil C'.

In addition, a crop shear 107 is provided on one side of the three bending rolls 105, and the cutting shear 107 is used to cut the front end and the defective portion of the coil C being transferred.

Thereafter, impurities including oil contamination on the surface of the coil (C) are removed through the washing unit 200 to be described later, and then dried through an air nozzle (refer to reference numeral 247 in FIG. 5).

A steam supply process by the steam generating unit 260 generating high-temperature/high-pressure steam sprayed by the plurality of steam nozzle units 245 will be briefly described with reference to FIG. 5 as follows.

As shown in FIG. 5 , the steam generating unit 260 includes a steam generating tank 261 having a built-in steam generating heater 265 for steam generating, and high temperature generated from the steam generating tank 261 / High-pressure steam may be supplied and sprayed at high pressure toward the upper and lower surfaces of the coil C of the washing tank 241 using the plurality of steam nozzle parts 245 .

At this time, the plurality of steam nozzle units 245 can be uniformly injected toward the outer surface of the coil C so that the amount of steam injected is 93 kg per hour (93 kg / hr) or more. This is to have a cleaning efficiency corresponding to the case of using a hydrocarbon-based solvent rather than conventional steam. As described above, in one embodiment of the present invention, in cleaning the surface of the coil (C), it provides an advantage of minimizing environmental contamination concerns by replacing the use of hydrocarbon-based solvents, which may cause environmental pollution, with steam washing instead of using conventional solvents. do.

Here, the water supplied into the steam generating tank 261 is water softened through a water softener 262 that receives tap water and treats it with soft water. After boiling, the vapor and liquid phases are separated through the steam separator 266, pass through the steam strainer (steam filter, 267), and then a plurality of steam nozzle units 245 by the intermittent control of the steam shut-off valve 268 can be supplied quarterly.

In one embodiment of the present invention, the plurality of steam nozzle units 245 may be provided in three pairs, three on the upper surface and three on the lower surface of the coil C, and as shown in FIG. 5, the steam nozzle housing ( 269), a pair of overheating heaters 270 are provided to additionally superheat the supplied steam, and then spray the steam into the washing tank 241 at a high temperature/high pressure.

In the annealing process, the coil C is unwinded in the uncoiler drum 100 to convert it into a strip shape. The first part of the coil (C) unwound above is transferred through the coil opener 103 configured on one side of the uncoiler drum 100, and through the coil opener 103, three bending rolls ( 105).

In the 3 bending rolls 105, initial flatness is given to the coil C and at the same time, when the coil C is transferred, it is positioned at the center of the line. In addition, the first part or defective part of the coil C that has passed through the three bending rolls is cut by a cutter.

Hereinafter, an overall working process using the recoiler device 1 according to an embodiment of the present invention will be briefly described as follows.

That is, after the coil C is unwound from the uncoiler drum 100, a washing and drying process and a flatness process are performed on the coil C transferred by the washing unit 200 and the leveler 300.

When the coil (C) that has passed through the cutter 107 needs a cleaning process, the washing unit 200, which is separated by sliding to the outside of the process line, is driven by the washing unit moving driver 230 to perform the cleaning process.

As the coil (C) passing through the stretch leveler 310 passes through the tension bridle 400, the tension with respect to the coil (C) is improved. The coil C, which has passed through the tension bridle 400, is secondarily improved in flatness while passing through the finish leveler 320.

As the coil (C) passed through the finish leveler 320 passes through the double pinch roll 500, the tension on the coil (C) is maximized, and the work process is completed.

After the completion of the working process, the winding process proceeds. In the winding process, the coil (C) is wound around the recoiler drum (800) after measuring the thickness and detecting the length of the coil (C) according to the state of the coil (C).

In the above, the recoiler device according to an embodiment of the present invention has been described in detail with reference to the accompanying drawings. However, it should be taken for granted that the embodiments of the present invention are not necessarily limited by the above-described embodiment, and various modifications and implementation within the equivalent range are possible by those skilled in the art to which the present invention belongs. will be. Therefore, it will be said that the true scope of the present invention is determined by the claims described later.
