Description

Up Looper System {UP LOOPER SYSTEM}

The present invention relates to an uploop system, and more particularly to an uploop system capable of extending the service life of an equipment by designing a position where the material contacts the roller when the material is transported on the roller, Lt; / RTI >

Generally, the molten steel produced in the steelmaking furnace is manufactured as a slab through a casting process and a rolling process, and the slab is manufactured as a steel material through a rolling process.

The rolling process is a method of processing a metal material of high or normal temperature into various types of materials by using a sintering of a metal. The continuous process of forming between two rotating rolls is used to reduce the thickness and width, Processing.

The rolling process includes a hot rolling process, a wire rolling process, and a cold rolling process. Among them, the wire rod rolling process is a work to produce wire rod having a diameter of 5 to 50 mm through billet injection, heating, rolling, cooling and correction (inspection and testing).

In the rolling section of the wire rod factory, an uploop system is provided which controls the tension of the wire rod and forcibly forms a loop in the material to secure the progress and quality of the material.

When the uploop system is normally operated, a loop is formed on the workpiece, and the workpiece is transferred on the roller. At this time, the workpiece is deviated from the path to be conveyed, so that it is difficult to perform a smooth up-loop work. In addition, as the material is continuously conveyed on the roller, abrasion occurs at the position of the roller to which the material contacts. As a result, the damage of the rollers proceeds quickly, and the rollers are replaced in a short period of time even though there is no abnormality in the portions where the rollers are not in contact with the rollers.

Therefore, there is a need for an uploop system that can smoothly perform an up-loop operation and extend the replacement period of the equipment to drastically reduce the maintenance cost.
