of rolling mills

A four high rolling mill is used for the hot rolling of armor and other plates as well as cold rolling of plates sheets and strips 4 Tandem rolling mills It is a set of two or three stands of roll It begins with comprehensive coverage of rolling processes and the mechanics of rolling which is the theoretical content of the subject This is followed by a chapter on 'rolling practices' that highlights plant level procedures and practices employed by the rollers for producing desired products


After a roll change or a mill stop rolls need some time to return to stable thermal conditions every new bar entering the mill creates an impact and sometimes there are really severe rolling accidents due to faults by operators weak rolled materials with internal defects or becauseMay 22 1973FIGS 1 and 1A constitute a composite top plan view partially in section of one form of rolling mill stand together with a roll changing arrangement therefor FIG 2 is a side elevational view partially in section of the equipment shown in FIG 2

Roll Changing Arrangement For A Rolling Mill


In a second aspect the invention provides a rolling mill including means to withdraw the roll assemblies therefrom the said means comprising a power source remote from the mill and a device comprising a series of links secured one to another to form an elongate chain-like arrangement and means between the power source and the mill to confine each end of each of the links to travel substantially in a given Such roll gap profile control can be carried out on mills equipped with work roll crossing and by making use of a combination of roll axial shifting and asymmetrical rolling In work roll shifting

Roll Cooling

The fundamentals for efficient and economical roll cooling are an optimized nozzle and header arrangement In the process of rolling the most significant aspect is the generation of heat through friction and deformation in the roll bite The study aims to determine effect of the fluctuating technological conditions of rolling on distribution of inter- stand tensions and loads of rolling motors for three variants of the continuous rolling mill with the speed control system only for electric drive of the rolling mill with properties of
