Short-stress-path rolling mill: It is assembled with four screws in series, with short stress path and great rigidity. The upper roller and lower roller can be adjusted symmetrically without changing the rolling center. Center distance adjusting range of two rollers: 0~110mm. By equipping with independent hydraulic station, it is easy and convenient to lift cardan shaft and change roller. Powered by DC motor, it has a wide range of speed regulation. Most of short-stress-path rolling mill lines are H/V type, which can process untwisted rolling in the whole line. Rough rolling and intermediate rolling can meet the requirements on rolling big billets and improving rolling precision, finish rolling is mainly responsible for improving rolling precision and speed (highest: 18m/s).
