As part of our fleet management process, we provide turnkey maintenance solutions for entire rolling mill chock fleets. sms group inc. offers full-service chock consumable components; inventory management; oil film bearing repair and failure analysis; and tracking of chock pressure acting on top backup chock, bottom backup chock, top work roll chock and bottom work roll chock cylinder force area 19.m 8.m, 13.m, 10.m respectivelyour foil mills feature a number of automated systems for coil, spool, and scrap handling as well as high speed work roll change; operation and drive-side work roll latching allows for thermal expansion of the rolls to the operator side. this is accommodated by bearing clearances which eliminates potential thrust forces on the mill spindles and work roll bending rams during long period passes

Monitoring Device For Roll Bearings In Rolling Mills

the monitoring device is constructed in such a way that the temperature measurement takes place directly at the bearing and there is no need for detaching connecting lines during changing of rolls. the main features of the monitoring device for roll bearings, installed, for example, in the chock of the work roll of a roll stand, reside in a thermal limit value pickup in contact with the roll bearing the roughing mill stands are used to reduce the thickness of the steel while at the same time extending the overall length. rolling mill stand is an important part of a work stand, roll bearing chock and roller adjustment device is installed on the frame. read more; camber for Hi mill work roll. camber for hi mill work roll humidity-consult.be.rolling mill chock assembly.

Analysis Of The Mill Roller Bearing Using Mixed Fast

new method named mixed fast multipole boundary element is introduced in this paper to solve the contact problem of mill roller bearing. incompatible elements and compatible elements are used to construct shape functions in non-contact area and contact area. On the one hand, mfm-bem avoids satisfying the conditions of precise coordination in compatible elements, on the other hand steel mill work. We are the heavy fabrication, machine and rebuild facility for many industries in the regional area. We have done extensive work in large steel mills, tube mills, sheet mills, pipe mills, aluminum plants, and scrap yards. piw has experience from the melt shops, reheat, cold mills, roll line and all other areas of the mill.marcegaglia palini & bertoli contracted danieli service to improve plate mill production in san giorgio di nogaro, italy. danieli service provided accurate restoration of mill housing geometrical tolerances, recondition existing backup and work roll chocks and supplied new danliners wear plates.contribute to many of the roll neck failures that occur in 2-hi mill work rolls or 4-hi mill back-up rolls.
