The roll mill is the simplest batch mixing equipment. The principal design consists of two horizontal rolls, usually of equal size, arranged side by side and rotating toward each other at different speeds. The ratio of the peripheral speeds of the rolls, known as friction ratio, ranges from 1 to 2 but is usually around 1.2.

Mill finishes, whether hot or cold rolled, are the basic supply condition for all stainless steel flat products. They are used universally for standard building components but are also the basis for subsequent finishing pro-cesses that alter the surface to meet more demanding architectural requirements. Four particular surface designations are im-

Journal Bearings and Their Lubrication. Journal or plain bearings consist of a shaft or journal which rotates freely in a supporting metal sleeve or shell. There are no rolling elements in these bearings. Their design and construction may be relatively simple, but the theory and operation of these bearings can be complex.
An important characteristic of HCrS is that the mill is not required to adjust special water cooling conditions. And in the rolling process these rolls can form oxide film to improve surface quality of rolled products. These rolls are suitable for both two-Hi roughing and early stand of four-Hi finishing for hot strip mills.
If not, then we can recommend a wire size given common safety factors. Typical safety factors are about 2 to 1 for a winch and about 5 to 1 for a hoist. As an example, if a wire has a 92 ton breaking load and you want to use a 5:1 safety factor, then the hoist you use should have no greater line pull than 18.4 tons.
A. Mechanical Braking Systems. The basic braking devices used by mechanical braking systems are: wheel-tread brakes, axle-mounted disc brakes, and wheel-mounted disc brakes. All these mechanisms use an object (a brake shoe or lining) that applies friction to the disc. The applied pressure is adjusted to control the braking force.
Four High Rolling Mills: In this type of mill, there are four parallel rolls one by another. In this operation, the rotation of the first and the fourth rolls take place in the opposite direction of the second and the third rolls. The second and third rolls are smaller to provide rigidity in necessity. So those are known as back up rolls.

finishing mills, which will roll the steel in tandem with one another. The workhorse roughing mill has 135" wide rolls for rolling 'broadside' (as the first roughing mill is commonly called) to make a slab wider. A 5,000 hp motor drives 42"-diameter work-rolls through 28:1 gears to reduce the slab's thickness by as much as 2-½".
Each debarker is sized and designed for the specific capacity and bark level requirements of the individual mill. The appropriate rotor diameter, the number of rotors, the rotor profile, and rotor disc spacing are all considered when sizing and designing a debarker, as are log species, diameter, and operating conditions.
The edging rolls are used to be mounted from the front of the mill stand, less frequently from the rear side, but sometimes also from both sides of the mill. Universal mill configuration is used for rolling of slabs, universal plates and …
If a mill rolls 80 % of the calendar year, that is 365 x 24 x 0.80 = 7008 hours. If the mill rolls 800,000 tons per year, it runs at an average production rate of …

In the tube mill, flat steel strip (1) is formed continuously around its longitudinal axis to produce a round tube. This is done by moving the strip through a progressive set of rolls (2-6). The strip edges (7) are heated by either high frequency induction or contact welding and then forged together by weld rolls to create a continuous ...
Hot Mill; Cold Roll Tin; Pickling and Cold Rolling; Galvanize Finishing starts in the Hot Mill with the reheating of a slabs in special ovens. Heated slabs are then run through a roughing mill which rolls the strip back and forth pressing the slab with extreme force to flatten the steel into a long continuous sheet.
This refers to mixing operations using horizontal two roll mills. The operator (usually known as a mill man) places the various ingredients in the nip formed between the rolls and mixes the compound by cutting it off the rolls and re-feeding it into the nip until all the ingredients are added. Mills are used not only for blending of
