More uniform load distribution by the stands will reduce the possibility of main mill lines equipment ...
GENERAL ASPECTS OF ROLL COOLING FOR HOT COLD ROLLING MILLS
rolling mill, dedied roll cooling systems are required to fulfill the required functions. Examples are suitable roll cooling and lubriionsystems to fully utilize the advantages of HSS rolls in hot strip mills, and selective roll cooling systems as a method to control the flatness of the strip in cold rolling mills.
roll pass design for blooming mill
Effect of pass schedule and groove design on the metal . using an FEM model during the initial passes in a blooming mill, as a function of three different pass schedules, roll groove depth, collar taper angle and corner radius The simulations predicted the effective strain penetration, load, torque, fish tail billet end shapes, and metal flow behaviour at a chosen temperature, .

· The above researches on roll pass or flower design are mainly for conventional roll forming processes. In conventional rollforming processes, a metal strip is gradually bent into desired shape by using contoured vertical and horizontal rolls mounted on roll stands, as shown in Fig. 1 ( Schuler, 1996).The formed strip at each stand is shaped definitely by the .
Rolling of Metals
Flat Rolling •Roll Force: F= LwY avg •Rollstrip contact length L •Average strip width w –despite the fact that spreading, or an increase in width, may actually occur if edger mills are not used •Average true stress of the strip in the roll gap Y avg •Assumes no friction and thus predicts lower roll force than the actual value

BEAMBLANK CASTING
Beamblank casting results in fewer passes in the section mill, reduced energy use and lower production costs. Nearnetshape casting is an energysaving alternative to conventional bloom casting for the production of beams and sections. The greatest benefits can be derived through the direct coupling of the caster to the rolling mill.
