2, adopt the wedge zeroing, realize the automatic adjusting of rolling absolute altitude, fluid motor-driven worm and gear, leading screw promote the wedge motion, stable working, and stepless speed regulation, self-locking is reliable, keeps the rolling line height constant in the work, satisfies need of work.
4, backing roll adopts the staggered combination of biserial to arrange that axial rigidity is big, has removed complicated negative kinking structure, with the amount of deflection of the just curved system balance working roll of working roll, has simplified the complicated technology of in the past making protruding roller, with flat rolling, can obtain the good product of plate shape; Because of having simplified the frame for movement part, can realize quick online replacing intermediate calender rolls, down intermediate calender rolls and upper and lower working roll, also can be non-onlinely change fast, the lower support roller.
5, roller is that rigidity is big, stable, and working roll median plane and intermediate calender rolls median plane dislocation 5mm produce couple in rolling, to obtain the stability of whole roller system, the needs of adaptation milling train left and right sides transmission.
6, arc is adopted in the back-up chock both sides, all establishes the arc cushion block up and down, to satisfy under roll neck wearing and tearing situation not of uniform size, still can well contact, and guarantees operate as normal; 7, backing roll, working roll, intermediate calender rolls bearing all are provided with oil gas lubricating system, and the rolling middle emulsion cooling and lubricating form that adopts guarantees that mill speed is the stability of 16m/sec in high-speed rolling production; 8, the utility model roller system arranges novelly, replaces large diameter single backing roll with biserial than the backing roll of minor diameter, and bracket height reduces, in light weight, rack construction is the closed framework structure, is 1/2 of same size rolling-mill housing weight, low to requirement on height of workshop, small investment.
