Rolling mill To roll the hot crude steel products into desired shape by passing and squeezing it between set of revolving rolls The rolls may be plain or grooved rolls depending on product Rolling operation may contain one or more roll stands depending on reductions required The Rolling Mill comprises of the following sections.
SMS SIEMAG Hot Strip Mills 8 The coilbox arranged between the roughing stand and the finishing mill of a hot rolling mill forms coils of transfer bars thus serving as both material and heat accumulator During uncoiling the former trans fer bar tail runs into the finishing mill as transfer bar head The coilbox is employed in new facilities.
During hot rolling of steel its surface is exposed to air which leads to oxidation resulting in scale formation The scale formation is affected by the temperature steel grade surrounding atmosphere and the exposure time There are two kinds of scales relevant in rolling mills sticky and dry scales.
