Abstract
본 발명은 로울크로스장치와 슬리브로울식백업로울을 구비한 압연기에 관한것으로서, 압연재의 판크라운과 복합신장등의 복잡한 판형상불량을 동시에 제어가능하게 하는것을 목적으로 한 것이며, 그 구성에 있어서, 압연재 S의 압연에 있어서, 축심이 압연판재의 판면에 평행인 면내에서 서로 크로스하도록 배치된 상하워크로울(11)을 구동회전하고, 마찬가지로 크로스배치한 상하백업로울(10)의 로울지지축(1)을 적절한 각도로 회동해서 상하의 워크로울(11)에 각각 크라운패턴을 형성하며, 상이 크라운패턴의 V형상크라운이 부족하면, 더욱 상하워크로울(11) 및 백업로울(10)을 그 축방향 중앙부를 중심으로, 유압실린더(15)에 의해서 상하로 서로 크로스시키고, 이 크로스각을 조절해서 압연재 S의 판크라운 및 복합신장등의 판형상불량을 제어하는 것을 특징으로 한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rolling machine having a roll cross device and a sleeve roll type backup roll, which aims at controlling simultaneously complicated plate defects such as a plate crown of a rolled material and a compound elongation. In the rolling of the rolled material S, the roll support shafts of the vertical back-up rolls 10, in which the shaft cores are driven and rotated so as to cross each other in a plane parallel to the plate surface of the rolled sheet material, 1) is rotated at an appropriate angle to form a crown pattern on the upper and lower work rollers 11, and if the V-shaped crown of the crown pattern is insufficient, the upper and lower work rollers 11 and the backup roller 10 are further axially rotated. Crossing each other up and down by the hydraulic cylinder 15 centering on the center part, and controlling this cross angle by controlling the plate shape defects, such as the plate crown of a rolling material S, and a compound elongation, etc. It will have a gong.
