摘要： The present invention is to provide a squeeze roll stand in which roll replacement of squeeze rolls is easily performed and a device structure is simple. In order to realize this, the squeeze roll stand includes a combination of a fixed portion 10 installed at a joint position of an electric resistance welded pipe manufacturing line, in which squeeze rolls excluding left and right upper rolls are detachably assembled, and a movable portion 20 overlying the fixed portion 10, inside which the left and right upper rolls are detachably assembled, the movable portion being inclined, taking the back surface side (line downstream side) as a fulcrum point, toward the same side from an assembling position on the fixed portion 10 to a retreat position to open an upper part of the fixed portion 10. The movable portion 20 is driven and reciprocated between the assembling position and the retreat position with cylinder type actuators 24 as a drive mechanism 40. At the retreat position, the movable portion 20 overlies a bead grinding device 50 arranged on the back surface side (line downstream side) of the fixed portion 10 with a front surface facing upward.
