연속용융도금공정의 표면적 향상 및 사행을 방지할 수 있는 포트롤{Pot roll that can improve surface area and prevent meandering in continuous melt plating process}Pot roll that can improve surface area and prevent meandering in continuous melt plating process

본 발명은 연속용융도금공정의 표면적 향상 및 사행을 방지할 수 있는 포트롤에 관한 것으로, 더욱 상세하게는 슬리브와 축수부의 표면적을 향상시켜 마모를 최소화하고 포트롤의 사행을 방지할 수 있도록 하는 연속용융도금공정의 표면적 향상 및 사행을 방지할 수 있는 포트롤에 관한 것이다.The present invention relates to a potroll capable of improving the surface area and preventing meandering in a continuous hot-dip plating process, and more particularly, it improves the surface area of a sleeve and a bearing part to minimize wear and prevent meandering of the potroll. It relates to a pot roll capable of improving the surface area of the hot-dip plating process and preventing meandering.

일반적으로 포트롤은 연속용융도금공정에서 도금조의 내부에 설치하여 스트립(강판)을 침지시키고 이송방향을 유도하는 역할을 수행한다.In general, the pot roll is installed inside the plating bath in the continuous hot-dip plating process to immerse the strip (steel plate) and guide the transport direction.

그러나 종래의 포트롤은 통과하는 스트립의 장력에 의해서 슬리브와 축수부가 맞닿는 표면적에 부하가 집중되는 문제를 갖게 되었다.However, the conventional portroll has a problem in that the load is concentrated on the surface area where the sleeve and the bearing part come into contact by the tension of the passing strip.

특히 슬리브와 축수부가 맞닿는 표면적이 협소하여 마모가 집중되는 구조적인 문제를 갖게 되었다.In particular, the surface area in contact with the sleeve and the bearing part is narrow, so there is a structural problem in which wear is concentrated.

또한, 마모가 발생하면서 포트롤의 사행으로 스트립의 이송효율 및 생산품질을 저하시키는 문제를 갖게 되었다.In addition, as wear occurs, there is a problem in that the transport efficiency and production quality of the strip are deteriorated due to the meandering of the pot roll.
