Rolling Mill Guide Equipments...

Rolling Mill Guide Equipments In hot rolling mills for long products, guide equipments guide the rolling stock at the entry and the exit of the roll pass so as to have smooth rolling of the rolling stock. The guiding equipments are to be sturdy, accurate and stable. Rolling mill guide equipments play a major role in ensuring the surface quality of the rolled product. The guides are to be designed for the wide variety of stock sizes and shapes which are normally encountered in the long product rolling. The guide equipments are usually classified in three ways namely (i) position with respect to the working stand (e.g. entry guide and exit guide etc.), (ii) method of construction, and (iii) type of friction between the rolling stock and the working element of the guide equipment (e.g. sliding or rolling etc.). Sliding or static guides The entry and exit guides of sliding type are also known as static guides. The design of these guides is based on sliding friction. These guides are usually comprise of a guide box, two opposed blocks mounted in the guide box on opposite sides of the mill pass line and having longitudinally extending channels in their adjacent faces, separate metal plates bridging the respective channels and shaped to fit closely against the sides of the rolling stock traveling through the guide, and means to circulate water through the channels in contact with the outer surfaces of the plates. Static guides are robustly designed guides to withstand the demanding rolling mill environment. The design of the guides is to suite the specific roll pass requirement of the mill. Static guides usually feature a common guide holder so as to allow for reduced requirements of stock and spares. These guides can be adapted...
