Roll Camber Design for Cold Rolling Mills ScienceDirect

Plant trials confirmed the validity of the predictions in wide cold rolling and temper rolling mills. On stands without roll bending facilities a traditional roll-preheating The mill roll (or camber) is usually ground to a parabolic shape to counteract the deflections developed during rolling.

Analysis of in-site grinding process using new equipment for calendar

The geometry, camber of rollers play a major role for most of the errors stated. This paper focuses on the experimental investigations carried out for cambering the rolls in-site (without removing), through grinding process with newly modeled equipment. The results obtained through in-site grinding are compared and discussed.Said roll-camber grinding apparatus is provided with a computer which automatically controls the feeding speed and the stroke of a grinding wheel by means of numerical control so as to precisely achieve a desired camber for a roller. However, such a roll-camber grinding apparatus is complicated in structure and very expensive to manufacture.Roll-camber grinding apparatus LIU; DANIEL

Roll Grinder Camber Calculations Automation & Control

I assume you refer to rolls used in strip production, that require a camber to counter the effects of bending, on thickness across the strip width. If so, then the camber is usually parabolic with y = ax^2. a is calculated using the centre displacement and length of roll. a = C/ (L/2)^2. C = camber in the centre. L = roll length.With rich experience and knowledge in this domain, we manufacture and exporter an extensive range of Auto Camber Roll Grinding Machine. The offered rang is designed and manufactured using superior quality basic parts as per the set industry norms under the guidance of skilled professionals.

are a discussion of crown contour vs. crown at center of roll, and the concept of compound crowning to allow for end relief in addition to a simple straight dub or taper. Modern problem solving tools for rolls and roll covers are available to Valmet's customers. These include computer simulations such as NipSim® for nip dynamics.crowning a roll is that it will yield improved product quality. And more importantly crowning helps the roll covering last longer, increases the rubber life and helps reduce machine down time. As discussed earlier, specifying a crown on a roller has to be taken with caution. This is especially true when grinding or cutting an accurate crown.The Basic Theory of Crowning Industrial Rollers
