Roll Camber Design for Cold Rolling Mills

Roll Camber Design For Cold Rolling Mills

Sep 01, 1976 Several alternative solutions to this problem are currently under consideration. COMMENTS AND CONCLUSIONS A 4-high mill stand rolling a given order has a characteristic shape variation wi th strip width. The optimum roll camber, for a particular strip width, can be predicted using a shape analysis algorithm with a modified convergence equation.

FE simulations of camber in hot strip rolling

Fe Simulations Of Camber In Hot Strip Rolling

Aug 01, 1998 The experiments were planned so that a large camber would be obtained. A total of 20 strips were rolled in MEFOSs four-high pilot mill. The mill specification and the conditions for the experiments are listed in Table 1. Two pairs of work rolls were used, one pair had a 0.3-mm convex crown and the other pair was cylindrical.

Introduction to Cambering

Introduction To Cambering

Natural mill camber, which is a slight camber present in a beam when it is received from the mill, will exist in most beams If the natural mill camber is at least 75% of the specified camber, no further cambering by the fabricator is required If camber is not specified, the beams will be fabricated and erected with

Study On Predictive Model Of Plate Camber

The plate camber is one of the thorny problems in the plate rolling process. The characteristic variables of plate camber at the delivery and at the entry sides of the mill were illustrated based on the primary concepts of camber. The relationship between the plate characteristic variable and velocity distribution in the deformation area of the plate was also determined.
