本文共叙述了四个主要部分: (一)介绍半机架式予应力轧机机架参数,选择的典型结构(见图)是二辊半机架式予应力轧机,予应力框架是“T”型上辊轴承座和半机架,由施加予紧力的拉杆紧固而构成。下辊轴承座可自由地在框架窗口中上下移动,并可借轴端单耳进行轴向调整。轧机的导卫装置都附设在拉杆上,而拉杆可绕固定点向外侧倾倒一定角度,这样,能实现迅速换辊。 This paper describes four main parts: (1) Introduction of the frame parameters of the semi-stand pre-stress mill, the typical structure of the selection (see photo) is a two-roll semi-frame prestressing mill, the prestressed frame is “T” Type of upper roller bearing and half-frame, by the tension applied to the composition of the rod. The lower roll chock is free to move up and down in the frame window and can be axially adjusted by a single-ended shaft end. Rolling mill guide devices are attached to the rod, and the rod can be tilted around the fixed point to the outside a certain angle, so that rapid roll change can be achieved.
