The roughing mill work rolls of many hot rolling mills in the world are faced with the problem of contact fatigue in the bonding and bonding zone before reaching the scrap diameter. This phenomenon is caused by factors such as rolling steel with high resistance to deformation, long rolling cycle, increased reduction in order to increase the ...
's Rolling Mill Rolls Support the World Steel Industry. In 1961, became the first company in the world to adopt the "centrifugal casting" method for the production of mill rolls. It enables to produce a multi -layer composite rolls, which revolutionized mill roll material .
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).
You face rolling problems in the finishing mill and an increased likelihood e.g. of tail end breaks. This is where camber-free rolling comes in. It's based on the interaction of roll alignment control integrated in our automation system and strong, position-controlled side guides in the roughing mill stand entry and exit sections.
Abstract. Equations are derived for the normal roll pressure, specific roll load and torque in hot rolling mills, using the condition for plastic deformation in rolling derived by Orowan, together with von Kármán's equation of equilibrium. Although applying strictly to the rolling of ideal plastic-rigid materials, these equations may be ...
Applications: These rolls are suitable for Roughing and Intermediate Mill stands of Blooming/Slabbing, TMT Bars Mills and Wire Rod mills. Rolls for Intermediate and Finishing Stands of Structure and Strip Mills. Common Grades: SG P 47 (45°-50° Sh C) SG P 53 (50°-55° Sh C) SG P 57 (55°-60° Sh C) SG P 63 (60°-65° Sh C) Mechanical Properties:
Rolling Mills. Pepetools engineered a unique housing that maximizes durability and increases strength, all while decreasing overall mass. Pepetools is proud to be the only American manufacturer to produce, design, and build rolling mills in the USA.
Today, cold and hot strip mills around the globe are continuously looking for ways to increase their productivity, save energy, lower their overall costs and improve the final quality of their products. Using lubricant in cold rolling and controlling the roll-wear in hot rolling are some of the ways to achieve these goals.

If interested, please mail at marketing2@hanrm.
Rolling mills generally come with gears to reduce the amount of effort needed to roll the metal. The more gears, the easier and smoother the roll. Basically if a rolling mill has a gear ratio of 4:1, you'll need to turn the handle 4 times for the rollers to rotate once.
At present, there is a trend of using bucket steel rolls to replace forged steel rolls. The roll of the 6VH billet continuous rolling mill in the Baosteel blooming mill is made of forged semi-steel and forged cast iron with 1.7% ~ 2.4% C, which has good wear resistance and poor hot crack resistance.
MBI Rolls, a division of M. Brashem, Inc., has provided the best value for quality, price and service to the steel industry for more than 30 years. We are a leading distributor of mill rolls to the north American steel mill industry, with significant share of the long bar market.
HSS rolls, often installed in the earlier stands of hot strip mills, provide improved wear resistance along with a better surface roughing resistance. However, HSS are rolls more sensitive during operation and require a higher grade of attention with regard to roll cooling than High-Cr rolls. HSS rolls need an adequate mill operating environment
Roughing Mill - an overview | ScienceDirect Topics. 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 . Get Price
Shore hardness is about 40-60, used in roughing mills of large, medium and small steel rolling mills and steel plate rolling mills. (3) Hard surface roller. Shore hardness is about 60-85, which is used for the roughing mill of thin plate, medium plate, medium section steel, and small section steel mill and the support roll of four-roll mill.

Rolling Mill Rolls. 1. Definitions. Rolls are a tool to produce plastic deformation of the metal. It is an important consuming part to determine the efficiency and quality of the rolling mill. Roll is an important part of the rolling mill. The pressure generated by a pair or group of rolls is used to roll the steel.
In two high reversing rolling mills, the rolls revolve ist in one direction and then in the various others, to ensure that rolled steel may pass to and fro via the rolls a number of times. This kind is made use of in plumbing and also slabbing mills and for roughing operate in plate, rail, structural, and also other mills.
