CSI''s Hot Strip Mill includes six finishing mills, which reduce the thickness of the transfer bar down to the gauge required by the customer or the next process. The rolling speed is set to allow the last stand to perform the final reduction at the finishing temperature, between 1500° to 1650°F, specified to reach certain mechanical properties.
Sep 11, 2014· The differences between hot rolled steel and cold rolled steel relates to the way these metals are processed at the mill, and not the product specification or grade. Hot rolled steel involves rolling the steel at high temperatures, where cold rolled steel is processed further in cold reduction mills where the material is cooled followed by ...
2+4 EVO Bar Reducing and Sizing Mill. The 2+4 EVO reducing and sizing mill uses a patented pass design. A reducing group with 2Roll stands with high reduction is followed by a sizing group with 4Roll stands with low reduction. While the 2Roll high reduction guarantees the desired metallurgical structure, the 4Roll low reduction provides ...

In the cold rolling process and the precision is strip thickness of cold rolled strips of key quality products. Conventional Automatic roll gap Control (where Gauge,
Integrated Mill Product produced from a BOF (Basic Oxygen Furnace) Mini Mill Product from Electric Arc Furnace Plate Flat rolled finished steel products within the following: .180" or thicker over 48" or .230" or thicker over 8" Strip Mill Plate Strip mill plate is leveled from coil.
best condition for rolling and the achievement of subsequent properties. The strip from the hot rolling mill is coiled for transport to the cold mill which might be on the same site or elsewhere. Cold mills, in a wide range of types and sizes are available; some are single stand, others 3 stand and some 5 stand (Figures and ).

Strip— Width: 750 mm or less. (Narrow plate or sheet). Fig. shows the successive stages in the reduction of a billet (100 x 100 mm) to a round bar. The billet is rotated at 90° after each pass. Principles of Rolling: The rolling is a process which consists of passing the metal through a gap between rollers rotating in opposite direction.

A temper mill is a steel sheet or steel plate processing line composed of a horizontal pass cold rolling mill stand, entry and exit conveyor tables and upstream and downstream equipment depending on the design and nature of the processing system.. The primary purpose of a temper mill is to improve the surface finish on steel products.. Components. A typical type of temper mill .

The rolling mill is equipped with a walking beam furnace with a capacity of 125 tons per hour. Blooms are descaled after exiting the furnace, and then proceed through a five stand roughing mill, a six stand intermediate mill, and an eight stand finishing mill. Dimensional control is maintained by optical laser gauges and manual micrometer checks.
Cold Rolled Steels can be joined using accepted welding practices. SURFACE FINISH Cold Rolled Steels are manufactured with a matte finish obtained by rolling with specially roughened rolls on the cold mill and the temper mill. This finish helps to maintain effective lubrication during metal forming and improves the appearance of painted surfaces.
The hot strip mill can produce products from 1,6mm to 13,0mm thick depending on the grade. From Saldanha thicknesses from 1,5mm can be supplied. See thickness ranges in Hot Rolled Price List. The dimensions available are given in the data sheet: Hot Strip Mill Product Dimensions (file reference ).

Cold rolled steel bar is subjected to an additional level of processing in a cold reduction mill, called cold finishing. During this process, the bar undergoes drawing to increase tensile strength, turning to remove surface flaws, grinding to produce closer dimensional tolerances and polishing to improve the finish.

John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014. Friction and Wear. Work rolls in hot strip mills wear due to friction between the roll surface and hot strip. (Backup rolls wear as well, but under pressure with elastic deformation, the friction is much less, except for the high work roll roughness in the last stand of a sheet rolling tandem cold mill).
