A reversing mill is a rolling mill in which the workpiece is passed forward and backward through a pair of rolls. The reversing mill is so named because the steel runs back and forth between the rollers, reducing the thickness incrementally with each pass. A reversing mill can be used to reduce material to gauge.

Description. In steel mills, slabs are rolled out to heavy plates with a certain plate thickness using reversing mills. During this process, unwanted geometrical deviations with respect to the vertical axis of the plate (camber) can occur. Furthermore, the plate movement through the rolling gap can differ from the desired straight movement.
Wide plate mills make it possible to achieve excellent performances in terms of mechanical characteristics for finished products, enabling cross rolling with sizing, broadside and reduction stages, conventional rolling, temperature controlled rolling, thermo-mechanical rolling, accelerated cooling/direct quenching.
Download Citation | Application of hot rolling lubrication on a reversing coil/plate mill | In the past decade, roll bite lubrication has been used in continuous hot strip (tandem) mills widely.
Plate: A plate is a product with a thickness > 6mm. Sheet: Product with thickness < 6 mm and width >600 mm. ... Two high reversing rolling mills: Two-high-reversing-rolling-mill. The work can be passed back and forth through the rolls by reversing their direction of rotation.
Each heavy-plate mill features its own individual layout. That depends on the product mix, the product geometries, and the installation site. Common to all mills are the main process sections: reheating furnaces, mill area with one or two reversing 4-high stands, plate cooling and hot plate leveler, cooling beds, shearing line, finishing line, heavy plate line, and heat treatment line.

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.
Single-stand reversing cold mills. Depending on the product mix, a single-stand cold rolling mill can deliver rolling capacities of 100,000 to 400,000 t/a. Rolling schedules can be carried out with an even or odd number of passes to maximize mill availability and performance.
Reversing roughing mill: forward pass with active edger rolls (Ettl et al., 2018). considered in (Ettl et al., 2018), where a model of the lateral plate motion is developed and utilized to examine how local asymmetric forces on the entry and exit side of the rolling gap affect the stability of the plate motion.
Single-stand reversing cold rolling mill unit is used to process the pickled and trimmed hot-rolled coil of carbon steel with various materials and a thickness of 1.2～6.0mm (under normal temperature) into cold-rolled coils of various specifications with required thickness and surface roughness through several times of rolling.

Tags Rolling Mills, Two High Rolling Miill; Two High Rolling Mills. Rolling mills are classified according to the number and arrangement of the rolls. A two high rolling mill can further be classified as a reversing and a non-reversing mill. All rolling mills have common construction that is independent of the specific type of rolling required: 1.
The reversing cold rolling mill is the all-rounder among the cold rolling mills: Here, thin strips, thick strips, soft grades, high-strength and ultra-high-strength strips can be rolled in succession on one and the same plant. The RCM is mainly used for low carbon steels, but is also a good solution for modern grades such as silicon steels.
INTRODUCTION In heavy-plate hot rolling mills, heavy plates are pro- duced according t customers’ requir ments. Typically, the thi kness and the width of the plates are pecified b customer. The thickness f the plate is reduc d in a rolling mill stand in successive, reversing rolling passes.
The material requirements of copper and copper alloys, including brass, bronze, and ever more new materials, are what determines the design of a cold rolling mill. It depends on your product mix and its required capacity whether the best solution is a tandem non-reversing or a reversing cold mill. SMS group offers you CVC ® plus 4-high, CVC ...

Aluminum Hot Rolling Reversing Mill Application Overview Temperature Control in the Hot Rolling Mill Aluminum sheet and plate products are used for a wide range of applications, including can stock, brazing, automotive and aerospace. These industries demand exacting tolerances and precise
Rolling of Steel Plates in a Plate Rolling Mill. Plate steel is defined as a flat, as-rolled or heat treated product of thickness of at least 5 mm and width of at least 1,200 mm. Plate steel is widely used steel product. It falls normally in the categories of carbon steel, high strength low …
control and slab shape correction. These systems allow the rolling of steel slabs into a top-quality transfer bar, which is then processed on the Steckel Mill. The Steckel Mill After exiting the roughing mill, the transfer bar travels to the key-stone of the SMART system – a 110-inch wide, four-high, reversing Steckel mill.
For the successful plate producer, the mill is more than the rolling stand(s) at its core. Ancillary processes, in cooling and levelling in particular, are vital to quality, and control of the process is the key to efficient asset utilization.
passed to the rolling mill, where it was rolled down to the desired gauge either in a single reversing-mill stand or in a series of mill stands. In the fourth step, the steel passed through a leveler, where it was flattened and straightened. Finally, the plate moved to the shearing department, where the
Some of the earliest literature on rolling mills can be traced back to the Swedish engineer Christopher Polhem in his Patriotista Testamente of 1761, where he mentions rolling mills for both plate and bar iron. He also explains how rolling mills can save on time and labor because a rolling mill can produce 10 to 20 or more bars at the same time.
