characters of four high cold mill, a new cambering scheme for four high cold mill is advanced in this paperhis scheme considered the need of production of multispecification products, as well as the control of roller ends contacthe most homogeneous transverse distribution of front tension is the control target and the.
The higher the precharge pressure the softer the spring rate low precharge pressure will make the system very stiff and may not allow sufficient float to let tramp iron through the mill, which may cause damage high precharge pressure will make the system very soft and the top roll bearing may continually rise up to its maximum lift.
A disadvantage of 2high rolling mills is the fact that the rolls are large in diameter giving you limited reductionhis is because of the roll flattening affecthis is when the actual diameter of the roll changes its shape under separating pressure, and the area being reduced under the roll becomes quite large.
a zmill or sendzimir mill is a machine for rolling steelnlike a traditional rolling mill this 20high cluster mill configuration utilizes cascaded supporting rolls to apply force on the small work rolls in the centerhis allows the application of a higher roll pressure without bending the work rolls, which would result in poor metal quality.
