These castings are rolled to the required dimensions by the rolling mill to produce steel products. The smelting and refining process for iron and steel in the BFBOF process involves the carbon reduction of iron ore (Fe 2 O 3 ) in the BF to make molten iron, and decarburization of molten iron in the BOF to make molten steel.
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 workrolls through 28:1 gears to reduce the slab's thickness by as much as 2 .
A roller mill uses cylindrical rollers that grind the grain when it goes through them, which requires less horsepower then a similar capacity hammer mill. A roller mill gets a more consistent grind and smaller deviation then a hammer mill by rolling the grain instead of hammering it.
· 2. Not suitable for lowmelting sticky or plasticlike material due to heat generation in the mill head as a result of mill fouling. 3. The mill may be choked if the feed rate is not controlled, leading to damage. 4. Presence of foreign materials like stone or metals which finds its way into the material due to inadequate garbling process. 5.
The rolls are 45 mm in diameter and 90 mm wide. The upper pair of rollers can handle sheet from mm to 5 mm thick. The grooved lower rollers are used to roll out square wire from 1 mm to 5 mm. The rolling mill is operated with a hand crank, a reduction gear making the work as easy as possible.
Primetals Technologies utilizes the Work Roll Shifting at hot strip rolling field for different two purposes: Dispersion of wear of work roll; Strip shape control (SmartCrown), as described in detail below: Mill stabilizing device (MSD) At today's demanding condition, maintaining stable operation of rolling mill is becoming difficult.
Directpressure milling occurs when a particle is crushed or pinched between two hardened surfaces. This can involve two rotating bars or one rotating bar and a stationary plate and can typically reduce oneinch or larger chunks of friable materials down to 800 to 1,000 microns. Examples include roll mills, cracking mills, and oscillator mills.
Two High NonReversing Mills: In these mills, two rolls continuously revolve in the same direction and we can't reverse the direction of the rollers. In this operation, the motive power is less costly. 2. ThreeHigh Rolling Mills: In this mill, the three rolls stand in parallel one by others.
Modern rolling practice can be attributed to the pioneering efforts of Henry Cort of Funtley Iron Mills, near Fareham in Hampshire, 1783, a patent was issued to Henry Cort for his use of grooved rolls for rolling iron bars. With this new design, mills were able to produce 15 times more output per day than with a hammer. Although Cort was not the first to use grooved rolls, he was ...
Basic diagram of the fundamental cold rolling process. Cold rolling process. ... Modern, efficient cold rolling mills can roll pickled sheets or strips at speeds of up to 4 m/s and tandem mills that are continuously working can produce up to million tons of cold rolled steel annually.
Our Roller Mill Equipment. Automatic's industrial grain roller mills produce precise particle size every time, even when it comes to high volume grain processing – as much as 15,000 bushels an hour for our hardestworking, highcapacity models. Parallel, corrugated rolls uniformly process corn and other grains to exactly the right size.

Years of experience helping the cement and power plant industries achieve easy operation and maintenance, energy efficiency and cost savings underpin our expertlydesigned vertical roller mill (VRM) product range. Whether grinding raw coal, clinker, cement and/or slag, we ...
1. Round – Limited used on surface grinders as well as feeding spindle bars ( boring mill). 2. Flat – This guideway is used for alignment only – normally outboard from the machine's spindle. Found on a wide range of machines including grinding machines. 3. Vee – Cylindrical grinders may have vee ways. They are outboard from the grinding wheel and are used primarily for alignment.

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.. The threeroll mill has proven to be the most successful of the range of roll mills which saw extensive development in ...
· Tumbling Mill (Rod or Ball) Mill TYPE E Has quadruple flanged construction. This also furnishes mill heads in two sections flanged and bolted in the center. All flanges are double welded. This type also reduces difficult transportation problems. Ball Mill Rod Mill Liners. The head and shell liners for BallRod Mills can be furnished of: Decolloy,
TwoHigh Rolling Mills: The twohigh rolling mill consists of a twohigh stand with two horizontal rolls, placed exactly one over the other. In this type of mill, one or both the rollers are adjustable. In its operation, the metal is passed between the two rollers rotating .
· Of course, rolls should be checked to ensure they have been installed on the correct stands. Once a year, the mill should be aligned. A mill alignment usually takes one or two days and is most often done by a professional. Every day, the mill operator should use a setup chart and follow all operating procedures.
TwoHigh: Generally, a 2HI mill is used for hot or cold breakdown and finishing of bar, sheet or strip. A wide range of sizes with separating force capacities from 10,000 lbs. ( MT) to over 3,000,000 lbs. (1360 MT) are available. ThreeHigh: A 3HI mill is an economic milling solution for the breakdown of rod and ingot. FourHigh: A 4HI mill may be used for finish rolling of thin gauge ...
III. Rolling mill: To roll the hot crude steel products into desired shape by passing and squeezing it between set of revolving rolls. The rolls may be plain or grooved rolls depending on product. Rolling operation may contain one or more roll stands depending on reductions required. The Rolling Mill comprises of the following sections: i.
