The rolling mill is equipped with a walking beam furnace with a capacity of 125 tons per hour. Blooms are de-scaled after exiting the furnace, and then proceed through a five stand roughing mill, a six stand intermediate mill, and an eight stand finishing mill. Dimensional control is maintained by optical laser gauges and manual micrometer checks.

must refer to your mill certificates and verify the average yield strength of the plate you are buying. It is not uncommon to find that the "mild" steel you are rolling will have actual yields in the 48,000 to 58,000-PSI range. Remember, machine capacity must match your material, and most plate roll manufacturers can provide detailed capacity-
SINGLE We build the best, and fix the rest Single Mills Get a uniform crack or crimp, for large or small grain, depending on the roll corrugation. Running a 1:1 differential, at a higher rpm (allowed by quality balanced rolls) than most other single pair manufacturers, allows for a greater capacity from the same size mill.
HC1700 grinding mill is a better choice for large scale powder-making projects. It effectively increases the production capacity while reducing the power consumption. Compared to the traditional mill (5R Raymond mill), the capacity of HC1700 grinding mill is about 2.5 to 4 times higher.
Feeding a roller mill directly from a screw conveyor or bucket elevator will cause surges in the feed rate that the roller mill "sees" instantaneously unless some damping system such as a surge hopper is used. Even though the feed rate averaged out over time may be within acceptable limits, the instant the surge hit the roll the feed rate

In hot rolling mills, premature failure of rolls is a major concern as it adversely affects the mill operation as well as production. Analysis of failed roll materials and actual rolling conditions in service are therefore necessary to understand the roll failure mechanism and thereby improve the wear resistance and extend the service life of rolls.
Lunn bar, fitted parallel to the mill rolls and positioned so that the operator works over it. The Lunn bar has proved effective in reducing the number of fata l and serious maiming injuries at two roll mills from their historical level of about 20 per year in the 1950s - 60s, …
A three roll mill or triple roll mill is a machine that uses shear force created by three horizontally positioned rolls rotating in opposite directions and different speeds relative to each other, in order to mix, refine, disperse, or homogenize viscous materials fed into it.
