rolling mills (8 stand roughing rolling mill, 4 stand intermediate rolling mill, and 4 stand finishing rolling mill) was built by Morgan-Sumitomo Heavy Machinery Co. Ltd.. In the 1980s, the aimed qual-ity of products was shifted toward high-value-added special steel quality, and, to achieve this, in 1986, a three-roll finishing rolling
The roughing mill stands are used to reduce the thickness of the steel while at the same time extending the overall length. Rolling mill stand is an important part of a work stand, roll bearing chock and roller adjustment device is installed on the frame.

A twin-stand Steckel Mill combines Steckel technology and tandem rolling. This mill type gives you the capacity to produce high-quality hot strip on a Steckel mill at production rates of 1 - 1.2 million t per year (without roughing stand) or up to 1.8 million tons per year with roughing mill.
The long product rolling mills can also be designed as a single strand mill or two strands mill. In two strands mills, rolling in roughing group of stands takes place in two strands and in such mills there are two sets of intermediate and finishing stands where the rolling takes place in single strand.
The steel roughing rolling mill stand is used to reduce the thickness of the steel while at the same time extending the overall length. Steel roughing rolling mill stand is an important part of a work stand, roll bearing chock and roller adjustment device is installed on the frame.

Roughing Rolling Mill. The roughing mill stands are used to reduce the thickness of the steel while at the same time extending the overall length. Rolling mill stand is an important part of a work stand, roll bearing chock and roller adjustment device is installed on the frame.
At the moment size 8 was being produced. Only the roughing mill was in use. We have 2 other mills, namely, the intermediate mill and the finishing mill which...
Roughing mill rolling of reheated slab: The roughing mill usually consists of one or two roughing stands in which the slab is hot rolled back and forth 5 or 7 times repeatedly to reach the minimum thickness requirement. The roughing mill also contains edger rolls that are used to roll the edge of slab and center it.
COLD ROLLING MILLS SMS group Extracts from various newsletters ArcelorMittal Dunkirk chose SMS Demag to supply new main gear units for the roughing stands of its hot strip mill. The modernization aims to ex-pand the product spectrum and cut the maintenance cost of the mill. Based on a study worked out by SMS Demag on the drives of the roughing
Consider the hot rolling of a low-carbon steel strip in a single stand roughing mill. Let the entry thickness of the slab be 20 mm and its width to be 2000 mm. Its resistance to deformation is taken to be 150 MPa. It is reduced by 30% using work rolls of 800 mm diameter, rotating at 50 rpm. The coefficient of friction is taken to be 0.2.
finishing rolling mill. Roughing mill with horizontal sliding reversible stand A different solution for a compact and very flexible roughing mill for special steel was designed and installed in an Italian plant for special steel production, based on horizontal sliding reversible stand.
In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change in its cross-sectional area.. The types of rolls used in rolling mills are depended upon the shape, size and the gap between the rolls and their contour. Because of workability and limitations in …
Rolling mills are often divided into roughing, intermediate and finishing rolling cages. During shape rolling, an initial billet (round or square) with edge of diameter typically ranging between 100–140 mm is continuously deformed to produce a certain finished product with smaller cross section dimension and geometry.
The mill rolls take an initial thickness reduction in preparation for the finishing stands, Steel temperature must be monitored to meet parameters and prevent roll damage. Solutions: SPOT R100 or LSP-HD 10.
Roughing Solutions for Billets, Blooms and Large Rounds. The roughing area plays an important role in the flexibility of production of a modern mill, the reduction of its layout space, the minimization of the costs of rolling and post-rolling operation. All with automatic operation and maintenance procedures, several applications are available:
Roughing rolling mill is a machine for rolling steel. Rough rolling is in the middle of heating and intermediate rolling mill, and its function is to process the heated slab by a roughing rolling mill into an intermediate blank that satisfies the finishing requirements (specification, temperature, surface quality, plate type).
Hani Tech design and manufacturer different types of roughing rolling mill, mainly are open type and closed type: 3Hi & 2Hi Horizontal roughing rolling mill, 2Hi Vertical roghing mill Stands, Housingless Mills, etc.
The roughing mill significantly reduces the thickness of steel while simultaneously extending the overall length of the product. Accurate length and speed measurements at the roughing mill require a well-engineered, reliable system due to the harsh environment that these gauges must operate in. Producing a uniform product prior to hot mill finishing ensures better quality and …
