The roughing mill is made up of six independent rolling mill stands, the last four of which incorporate small vertical rolling mills called edgers. Slabs heated in the furnace until they glow bright orange-yellow are rolled through one stand at a time to produce so-called transfer bars suitable for finish rolling. High-pressure water-jet
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.

The process starts when the rolling mill gets aluminum slabs or billets ready for rolling. Depending on the desired materials properties for a particular roll, they must first decide whether to heat the stock or not. If they do not heat the aluminum before rolling, the aluminum will be cold worked.
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

the Flex Mill. It consists of a thin-slab caster, a tunnel furnace, and a rolling mill with six stands and one downcoiler. Caster The cast slab thicknesses range from 55 to 85 mm (2.17 to 3.35 inches) and allow the mill to "flex" between heavy and light gauges, as well as meet reduction ratios required in producing demanding steel grades.

1. Introduction. Strip breakages in steel rolling mills result in loss of production due to mill stoppage and may also cause damage to equipment. The magnitude of loss is even higher in the case of integrated processes like Thin Slab Casting and Rolling (TSCR) where all the processing stations are interlinked .In such a case, mill stoppages may affect upstream processes and can also …

Thin-slab casting and rolling processes are well known and have been in continuous development since their introduction at the end of the last cen-tury. In an attempt to find the optimum configura-tion to be able to economically operate and fully load the rolling mill, several different concepts have emerged that include up to three casting ...

The models employed by the mill automation are updated with the rolling parameters and product measurements each time a new slab is rolled, continually optimized the mills' automation set-ups. Product quality and production yield benefit from scheduling products with similar gauge and grade to roll in succession, allowing automation to deploy ...
rolling, plate mills, slabbing mills and blooming mills. Companies such as Mesta, United, Blaw-Knox, Lewis, Continental, and Bliss were attributed to building some of the largest rolling mills in the world
Before slabs can be rolled into hot rolling mills, slabs should be heated to the deformation temperature using reheating furnaces. Achieving this heating temperature is a major constraint of this ...
The cold rolling mills use the motor to drag the reinforcement, and the load-bearing roll and working roll of the cold rolling mill jointly apply the force to the two surfaces of the reinforcement. By changing the gap between the two rolls, the purpose of rolling cold-rolled ribbed bars with different diameters is realized.
The mill speed is kept optimum so as to finish the Hot rolling process well above the re-crystallisation temperature. We have manufactured 2Hi Hot Rolling Mills upto slab size of 150 mm thick x 1270 mm width for Non-Ferrous metals and 5Hi Hot Rolling Mills for flats/ plates upto 50 mm thick x 800 mm width for Stainless Steel.

These slabs are inspected, scarfed and then reheated in slab reheating furnace to the rolling temperatures before being rolled to hot rolled coils in a semi continuous or continuous hot strip mills. Development of thin slab casting and rolling (TSCR) technology is a step forward to reduce the number of process steps in the production of hot ...
Slabs are the feed material for hot strip mills or plate mills and blooms are rolled to billets in a billet mill or large sections in a structural mill. The output from a strip mill is coiled and, subsequently, used as the feed for a cold rolling mill or used directly by fabricators.

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…
Hot-rolling • The first hot-working operation for most steel products is done on the primary roughing mill (blooming, slabbing or cogging mills). • These mills are normally two-high reversing mills with 0.6-1.4 m diameter rolls (designated by size). • The objective is to breakdown the cast ingot into blooms or …
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.
Second, the red-hot slab was passed to a scale-breaker, where the hard iron-oxide covering ("scale") that had formed on the surface of the reheated steel was broken up and removed by fluted rolls and high pressure water sprays.1 Third, the de-scaled slab passed …
A slab is a length of metal that is rectangular in cross-section. The slab is created directly by continuous casting or indirectly by rolling an ingot on a slabbing mill. Slabs are usually further processed via flat rolling, skelping, and pipe rolling. Common final products include sheet …
Hot rolling takes advantage of the metal's ductility at high temperatures to execute great section reductions. Flat product hot rolling mills are fed from flat slabs, previously heated and homogenized in reheating furnaces in order to achieve suitable temperatures for the subsequent transformation process.
