Abstract

PURPOSE: An automatic polishing device of a rotary roll is provided to improve the quality of a strip surface by automatically removing dents on the surface of a rotary roll transferring a strip. CONSTITUTION: A strip passes a cool polishing process after a hot polishing process. After offering a heat resource to the surface of a strip to make possible plating work in a heating furnace, a zinc coating work is completed by passing a zinc plating furnace. Herein, a dent is produced. To remove the dents, an automatic polishing device is installed on the lower of a rotary roll. A pinion gear in a gear box(31) moves a rack(34) up and down by driving a motor(33). A first trolley(40) and a second trolley(50) move upward. If the automatic polishing device is placed under the rotary roll, a motor(54) is driven to move the second trolley to the left and right. The second trolley is placed under the rotary roll accurately. Herein, the second trolley is slid on the upper part of a rail(53). By moving forward support stands(60,61) by driving cylinders(70,71), a polishing piece(80) contact to the rotary roll. The surface of the rotary roll is polished. Thereby alien materials on the surface of the rotary roll are removed.

Description

회전롤 자동 연삭장치Rotary Roll Automatic Grinding Device

본 발명은 스트립 진행을 위하여 사용되는 회전롤의 표면결함으로 인한 스트립 표면의 덴트(dent)형성을 제거하기 위하여 회전롤 표면을 자동연삭 하는 장치에 관한 것이다.The present invention relates to an apparatus for automatically grinding a rolling roll surface in order to eliminate dent formation of the strip surface due to the surface defect of the rotating roll used for strip progression.

도 1은 연속주조 공장의 일부를 설명하기 위한 공정도로서, 일반적으로 용융아연 도금강판은 냉연공정에서 재가공될 때 스트립은 가열로 및 아연도금조(11)를 통과하면서 표면에 아연코팅 작업이 이루어진다. 이와 동시에 쿨링타워(10) 상부측에 설치된 회전롤(20)에 고온에서 발생되는 이물질 및 아연 조각등이 롤 표면에 협착 되고, 이로 인하여 스트립 표면에 덴트(dent)결함을 유발시킨다. 이로인하여 종래에는 덴트 결함 현상이 심할 경우에만 라인을 일시적으로 정지한 후, 회전롤(20) 표면에 박힌 덴트등을 작업자가 제거하게 된다. 또한 라인을 저속 운전한 후 회전되는 롤 표면에 작업자가 직접 사포등을 이용하여 덴트를 제거한다. 이러한 경우 작업자가 회전롤에 휘감기어 안전사고를 유발하게 되는 문제점이 있다. 또한 덴트로 인하여 스트립 표면에 흠이 발생하게 되고, 이로 인하여 스트립의 품질을 저하시키는 문제점이 있다.1 is a process diagram for explaining a part of the continuous casting plant, in general, when the hot-dip galvanized steel sheet is reworked in the cold rolling process, the strip is passed through the heating furnace and the galvanizing bath 11, the zinc coating is performed on the surface. At the same time, foreign matter and zinc fragments generated at high temperatures in the rotary roll 20 installed on the upper side of the cooling tower 10 are constricted on the roll surface, thereby causing a dent defect on the strip surface. As a result, in the prior art, the line is temporarily stopped only when the dent defect phenomenon is severe, and the operator removes the dents, etc., stuck in the surface of the rotary roll 20. In addition, the operator removes the dents using sandpaper or the like directly on the roll surface after the line is operated at low speed. In this case, there is a problem that the worker is wound around the rotary roll to cause a safety accident.
