The Hot Rolling Process - California Steel
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

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 ...
Rolling Mills | Industrial Efficiency Technology & Measures
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 some products (e.g. reinforcement bars, steel plates) only require hot-rolling, some others may require both hot– and cold ...
ROLLING-(A Brief Guide To Rolling And Rolling Mills)
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.
Roughing Mill - an overview | ScienceDirect Topics
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.

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.
Rolling Mill - Gallatin Steel
The rolling mill has six stands, numbered F1 - F6 from south to north. Before rolling, the slabs are 55mm or 65mm thick. Each stand applies millions of pounds of force to reduce the steel in successive passes to the desired thickness, producing gauges as thin as 0.055".
What is the function of rolling mill? – forwardonclimate
Rolling mills are machines which are used to process metal. They vary in size from bench-mounted hand-cranked mills used by jewelers to massive rolling mills utilized in industrial metals production and processing. The primary function of a rolling mill is to shape the metal being passed through the mill in some way,….
Rolling of steel in Hot Strip Mill – IspatGuru
The slab is rolled in roughing mill 5 or 7 times repeatedly to reach the minimum thickness requirement of around 30 mm. The roughing mill also contains edger rolls which are used to roll the edge of slab and center it. The hot strip mill can be either a high performance mill or a compact mill.
