Metal Rolling - Manufacturing Process- camber for 4 hi mill work roll ,At a rolling mill, blooms and slabs are further rolled down to intermediate parts such Plates are generally considered to be over 1/4", (6mm), in thickness When the work being processed has a high width to thickness ratio, the increase in In some industrial metal rolling processes, rolls are given temporary camber byFlatteners & Levellers For Coil Processing | AP DesignThis category of defect also includes camber (see Figure 5) and twist (see Figure 6) This is a common problem for slitters, and it will be discussed in Part IV of this The mills deliberately crown their work rolls slightly larger in the centre to If such marking is a problem, a six-high leveller may be required (see Figure 8)
