Embodiment Construction

[0013] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily implement the present invention.

[0014] figure 1 is a block diagram schematically showing a winding device according to an embodiment of the present invention.

[0015] refer to figure 1 , the coiling device 100 of an embodiment of the present invention may include a coiling model calculator 110 , a position controller 120 , a pinch roller part 130 and a coiler part 140 .

[0016] The coiling model calculator 110 can calculate the load and moving distance of the upper pinch roller 132 of the pinch roller part 130 according to the material information of the steel plate s, so as to adjust the bending of the steel plate s.

[0017] The material information of the steel plate s may be at least one of the thickness, steel type, and initial shape of the steel plate s.

[0018] The position control...

Abstract

The purpose of the present invention is to provide a coiling device in which a steel plate entering a coiler in a hot-rolling line is appropriately wound around a coiler mandrel. A coiling device according to one embodiment of the present invention may comprise: a pinch roll part provided with an upper pinch roll to bend a steel plate; a coiling-model calculator which calculates the weight and moving distance of the upper pinch roll according to material information about the steel plate, and moves the position of the upper pinch roll along the traveling direction of the steel plate; a position controller which moves the vertical position of the upper pinch roll according to the calculation values of the coiling-model calculator; and a coiler part which coils the steel plate that is bent by the pinch roll part.

Description

technical field [0001] The invention relates to a coiling device. Background technique [0002] Generally, in the coiling process of the hot rolling line, the front end of the strip passes through a pair of pinch rolls and then bends downward. The curved strip front end is then wound and rotated around the mandrel between the mandrel and helper rolls surrounding the mandrel. Then, after a predetermined time has elapsed, the mandrel expands to the outside of the circumference, tension is generated between the pinch roller and the mandrel, and winding is performed simultaneously. [0003] The pair of pinch rolls are in a fixed state regardless of the thickness, steel type, and initial shape of the strip, so it is difficult to obtain the desired curved shape at the front end of the strip for extremely thin or thick materials. . Therefore, there is a problem that the winding quality of the extremely thick material is kink, and the tension of the extremely thin material is ins...
