Over the last 25 years the thin slab casting and rolling process has been gaining market share in the production of hot-rolled strip, progressively eroding the advantages in certain finished-product categories that previously had been the exclusive domain of conventional mills.
Some ingots are sent directly to a universal plate mill for immediate rolling of steel plates. Most ingots, however, are sent to semifinishing mills (also known as slabbing or blooming mills) for reduction and shaping into slabs, blooms, or billets. A slab is generally a large flat length of steel wider than a bloom, a bloom is a length of ...
a high-capacity rolling mill for the reduction, into blooms, of steel ingots of large cross section, with masses up to 12 tons and larger. In some cases a blooming mill is used for the rolling of slabs and also shaped pieces (for heavy I beams, channel iron, and the like).

Rolling speeds at the finishing mill will be higher than at the roughing mill. Hence rolling cannot be done with stock present in both roughing and finishing mills. Finishing mill rolling of reheated slab: The finishing mill usually has five to seven finishing roll stands, which reduce the thickness of the transfer bar down to the gauge required.
At a rolling mill, blooms and slabs are further rolled down to intermediate parts such as plate, sheet, strip, coil, billets, bars and rods. Many of these products will be the starting material for subsequent manufacturing operations such as forging, sheet metal working, wire drawing, extrusion, and machining.

Thread Rolling Figure 13.16 (a) Features of a machined or rolled thread. (b) Grain flow in machined and rolled threads. Unlike machining, which cuts through the grains of the metal, the rolling of threads causes improved strength, because of cold working and favorable grain flow. Figure 13.15 Thread-rolling processes: (a) and (c) reciprocating

send to the roughing train of the mill for rolling process. b) Roller table: To discharge the hot blooms/billets/slabs to rolling mill for rolling operation. III. Mill Section: To roll the hot blooms / billets / slabs etc. into desired shape by passing it between set of revolving rolls. The rolls may be plain or grooved rolls depending on product.
ROLLING MILLS H Schneider Adapted from 3rd edition Encyclopaedia of Occupational Health and Safety Acknowledgements The description of hot and cold rolling mill operations is used with permission of the American Iron and Steel Institute Hot slabs of steel are converted into long coils of thin sheets in continuous hot strip mills .
Slabs from the Cast Shop are reheated and each glowing piece is hot rolled down to a thickness no greater than a deck of playing cards on our Hot Rolling Mill. This is the centerpiece of the PMX process, distinguishing us from conventional brass mills.
The raw material for both plate and coil rolling mills is obtained from continuous casting slabs with low to medium carbon content. Slabs are stored at the plant's yard and, after being flame cut to required dimension, they are moved to the reheating furnace.
Jul 02, 2021· "The rolling mill represents the hope and the desire to enter new markets in order to meet and satisfy our clients' needs," said Paulo López, Rolling Mill Director of the Ternium Industrial Center. All the steel slabs processed at the Pesqueria plant move through the Port of Brownsville.
Rolled from heavy slabs supplied by a slabbing mill or continuous caster or sometimes rolled directly from an ingot, plates vary greatly in dimensions. The largest mills can roll plates 200 millimetres thick, 5 metres wide, and 35 metres long. These three dimensions are determined by the slab or ingot weight as well as the rolling-mill size.
The 3Hi Cold Rolling Mill is used mainly for breakdown rolling of thick sheets/ plates of metals like Copper, Brass and Aluminum where the weight of sheet is on the higher side. It is difficult to return such heavy sheets back to the operator after the pass so the 3Hi Mill is advantageous in such scenario because it provides for reversible ...
Rolling mill computer systems calculate setpoints for rolling using extremely complex mathematical models and send signals to engage the descale sprays and to bring the mill roll stands to speed and set the roll gaps. The rolling mill has six stands, numbered …
be produced on different lines: hot rolling mills, plate mills, Steckel mills, thin slab compact strip mills [1]. For plate rolling these are plates of thickness 6-25, width up to 2500 mm and thickness 20-50 mm., width up to 2000 mm. For coils these are strips of thickness up to 12.5 mm and width up to 1850 mm.
In heavy plate rolling mills steel slabs in different dimensions (e.g. 1000×1000×200mm, 2000×1500×900mm, 4000×2000×400mm. . . ) are heated-up to temperatures between 800 and approx. 1150 C and then rolled into plates for the shipbuilding industry, offshore applications (drilling rigs, pipelines. . . ) or the…
In rolling mills, intermediate steel products are given their final shape and dimension in a series of shaping and finishing operations. Most of the slabs are heated in reheating furnaces and rolled into final shape in hot– or cold–rolling or finishing mills. While …
Dec 03, 2015· Rolling of steel slabs in hot strip mill consists of several sub-processes and at the end of them the final product 'hot rolled coil' is produced. The main sub-processes are (i) heating of steel slabs in the reheating furnace, (ii) descaling of the …
Blooming mill also produces shaped beam blanks requires for rolling heavy beams and channels sections. Slab is a rectangular product with thickness varies fr om 50 to 300 nun and width from 500 to 1800 nun or even more. Slabs are rolled from ingots either in a Blooming or Slabbing mill. Slab is an initial material for rolling of flat products.

In Vario rolling mills, induction heating is used after the first roll stand. This is an innovative technology for production of micro-alloy steel grades in API quality or better. Induction heating ensures a uniform temperature level between the first rolling mill stands, enabling greater relative thickness reduction.
Planetary-rolling-mill. Planetary rolling mill consists of a pair of heavy backing rolls surrounded by a large no of planetary rolls. Each planetary roll gives an almost constant reduction to the slab as it sweeps out a circular path between the backing rolls and the slab.
