The steel roughing rolling mill stands are 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.
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.
on wear is another issue. Stresses from Hertzian pressure in 4-high cold mill back up rolls were measured years ago, the results were never published, but of high interest - also, maybe later. K. H.

Modern rolling practice can be attributed to the pioneering efforts of Henry Cort of Funtley Iron Mills, near Fareham, England. In 1783, a patent was issued to Henry Cort for his use of grooved rolls for rolling iron bars. With this new design, mills were able to produce 15 times more output per day than with a hammer. Although Cort was not the first to use grooved rolls, he was the first to ...
Our rolling mills are available in both 2Hi and 4Hi roll configurations, and mills may be either work roll driven, back-up roll driven, or a combination of both. On one end of the spectrum, 4Hi mills with work rolls are offered as small as .500" (12.7mm) in diameter.

As a joint owner of the South Korean machine building plant BUKANG (Incheon city) that was founded in 1986 and currently is a leading manufacturer in the South Korea specializing in production of interchanging equipment and spare parts for various metallurgical units, manufacturing and engineering company ENCE offers rolls of rolling mills (mill rolls).
Jun 19, 2017· Roll pass design is an essential part of long product rolling process, since the long products are rolled between the shaped rolls in the long product rolling mills. Roll pass design generally means the cutting of grooves in the roll body through which steel to be rolled is made to pass sequentially to get the desired contour and size.
Xtek has manufactured Forged and Specialty Rolls for over 70 years. Special steel chemistries, coupled with unique and proprietary heat treating methods, have led to products with superior metallurgical properties and are the reason that Xtek is one of the leading suppliers of Forged and Specialty Rolls for many rolling mill applications.
They are applied in roughing mills and in rolling mill intermediate stands. Forged Steel Work Rolls For Cold Strip Mills They are refined by the most modern melt shop processes, forged in hydraulic presses, resulting in excellent chemical purity, metallurgical structure and high toughness, for application in rolling mills under most stringent ...
The Tredegar rolling mill's most famous work was the plates made for the ironclad C.S.S. ia. Power is transferred from a turbine or waterwheel to a set of gears, which drive a series of stands of rolls. Heated metal is elongated and shaped as it passes through each set of rolls. The rolls here, called roughing rolls, shape the metal first.
Forged Rolls Forging is a process in which the cast ingot is heated in the furnace & then material is hammered according to the customer's required specifications. Thereafter heat treatment is done in annealing furnace.
AC adjustable speed motor drive systems are the preferred technology for new rolling mill installations and modernization projects. TMEIC designs and manufactures two types of AC solutions for this purpose. Salient pole synchronous motors that meet the high power and torque demands of a hot strip mill, as well as roughing and finishing stands.
In two high reversing rolling mills the rolls rotate ist in one direction and then in the other, so that rolled metal may pass back and forth through the rolls several times. This type is used in pluming and slabing mills and for roughing work in plate, rail, structural and other mills.
Tungsten carbide rollers can be divided into solid carbide rolls and composite hard alloy rolls according to the structure. Solid carbide rolls have been widely used in pre-finishing and finishing stands for high-speed wire rod mills (including fixed reduction racks, pinch roll stands).
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
The workhorse roughing mill has 135" wide rolls for rolling 'broadside' (as the first roughing mill is commonly called) to make a slab wider. A 5,000 hp motor drives 42"-diameter work-rolls through 28:1 gears to reduce the slab's thickness by as much as 2-½". The last four roughing mills each incorporate edgers for width control ...
Forged steel rolls for Hot-rolling Mills Blooming, slabbing and breakdown mills, as well as roughing stands of section and structural mills require that the rolls endure high temperatures and heavy dynamic loads. Solid-forged rolls made of carbon tool steels are characterized by .
The work roll in chromium steel is the typical type of roll for the roughing stands of a hot strip mill. This application, very hard from a thermal point of view, needs rolls made in high-strength alloys that can withstand heavy rolling loads and wear at high temperature.
