x These mills are normally two-high reversing mills with 0.6 -1.4 metres diameter rolls (designated by size). x The objective is to breakdown the cast ingot into blooms or slabs for subsequent finishing into bars plate or a number of rolled sections. x The blooms/slabs are heated initially at 11000 C -13000 C. In hot-rolling of steel the

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 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.

SteelSteelBillets bars and rods Billets are the feedstock for long products of small cross section. In cases when they are not directly cast by a continuous caster they are rolled from blooms by billet mills. One method of rolling billets which are usually 75 to 125 millimetres square is to use a three-high mill with box passes as shown in A in the figure. After a rectangular

Rolling mills normally prefer to source slab internally for a number of reasons for example raw material optimisation flexibility on specifications and shorter lead times. In addition rolling investments are Rolling mills normally prefer to source slab internally for a number of reasons for example raw material optimisation flexibility on specifications and shorter lead times. In addition rolling investments are often very large and the addition of an internal casthouse is a modest component.

Before rolling high-pressure water jets descale the slabs. Most plate mills are four-high mills as shown in C in the figure and are supplemented by vertical edge rolls. The work rolls and backup Before rolling high-pressure water jets descale the slabs. Most plate mills are four-high mills as shown in C in the figure and are supplemented by vertical edge rolls. The work rolls and backup rolls of large mills have diameters of 1.2 and 2.4 metres respectively and a roll face length up to 6 metres.

In the rolling mill the slabs are reduced in thickness to the required gauge by passing through a 2-high reversing slab mill and a 4-high reversing Steckel mill where the plate is leveled and cut to length.

A rolling mill is used to straighten and/or change the thickness of sheet metal slabs or ingots. Rolling mills can also be used to add texture and shape to metals depending on the need and the rollers that are installed in the machines.

Rolling is most often (particularly in the case of the conversion of an ingot or continuous casting) performed hot. 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

HOT STRIP MILL — HIGHEST PERFORMANCE FOR NEW AND EXISTING STEEL MILLS The demand for hot rolled strip is growing in multiple ways. To remain competitive new and existing mills must meet this challenge in the best possible way. The production of hot strip is a

The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77 000 hp and finally coiling up the lengthened steel sheet for transport to the next process.

Rolling mills are not a standard machine tool nor are they built for stock. They are designed and built-to-order to specifically accomplish an end product or process. At one point during the industrial revolution in America the United States led the world in hot and cold rolling plate mills slabbing mills and blooming mills.

Rolling Mill. The Rolling Mill accepts the slabs arriving from the tunnel furnace rolls them to the proper thickness or gauge to meet the customer s order and sends them through the runout table cooling water sprays to the coiler where they are wrapped in a spiral to form coils.
