The conventional mill stands consists of housing and cap assembly wherein the rolls rotate in bearings-fiber/anti friction …
One is the production line of centrifugal cast work rolls for hot strip mills and wide & heavy plate mills, which can produce all kinds of centrifugal rolls from φ400×2000mm to φ1600×10000mm, covering the material of ICDP, high chromium iron, high chromium steel, HSS, semi-HSS, with the annual production capacity of 35000 tons.
We discuss several drive mechanisms for the working stand in periodic cold-rolled pipe mills. This paper focuses on identifying opportunities to increase mill capacity and modernize existing periodic cold-rolled pipe mills. We provide a comparative analysis of a variety of systems for equilibration of the dynamic forces in the working-stand drive mechanism.

Cold rolling mill is a new type of steel bar cold rolling equipment. The machine can process hot-rolled wire rods and circles with a diameter of 6.5 mm to 12 mm into cold-rolled ribbed bars with a finished specification diameter of 5 mm to 12 mm. The cold-rolled ribbed steel bar rolled by cold rolling mill is an updated product of cold drawn ...
This is accomplished by arranging the components of the mill so that both the vertical rolls and the horizontal rolls may be removed as a unit therefrom. With my arrangement, a roll change can be made in a matter of minutes whereas in the past, rolling mills of this type required as much as 8 hours to withdraw and reinsert the work rolls.
