Finish Strip Size Based Roll Sizing For Cold Reduction Mill Introduction

1301 The Rolling of Aluminium: the Process and the Productbest 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 1301.02.03 and 1301.02.04).

2B, 2D and BA Cold Rolled FinishesNo. 2B - A smooth, moderately reflective cold-rolled annealed and pickled or descaled finish typically produced by imparting a final light cold-rolled pass using [large diameter] polished rolls. This general-purpose finish is more readily polished than No 1 or 2D finishes. Product with 2B finish is normally supplied in the annealed plus lightly cold-rolled condition unless a tensile-rolled

This chromium and molybdenum based alloy is electric furnace melt, vacuum degassed, stress relieved, and machine straightened. It is offered in the turned ground and polished condition; with a "near" bearing-fit precision tolerance. Surface finish is approximately RMS 12/15. Typical tensile strength is Cold Rolled Steel - Metal SupermarketsHot rolled steel is typically cheaper than cold rolled steel due to the fact that it is often manufactured without any delays in the process, and therefore the reheating of the steel is not required (as it is with cold rolled). When the steel cools off it will shrink slightly thus giving less control on the size and shape of the finished product when compared to cold rolled.

and processed through a set of sizing/shaping rolls which cold-form it into a round (9), square (10) or rectangular (11) section. Form-Square Weld-Square (ERW) Process In the weld mill, driven forming dies progressively shape the flat strip (1) by forming the top two corners (2) of the square or rectangular tube in the initial forming station.

Tata Steel - Cold-rolled steelTata Steel offers a comprehensive range of cold-rolled steel comprising both continuously-annealed and batch-annealed products. This means we can tailor our offer to meet your precise requirements for formability, strength, surface finish or flatness.The Basics of Thread Rolling - PMPAThread Length vs. Roll Length o Roll work face needs to be calculated for each part to make sure proper clearances are used. o We offer this as a free service to our customers to make sure that the thread roll process and tooling life are optimized. o Rule of thumb = Roll WF = (2.5 x Pitch) + Thread Length CJWinter |

The Hot Rolling Process - California Steel IndustriesThe Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, reduction at the finishing temperature, between 1500° to 1650°F, specified to reach certain mechanical properties. By now, the steel has been rolled into a flat bar as long as 200 feet. In contrast to the roug hing mills, the finishing mills

JSW - Hot RolledJSW Steel manufactures Hot Rolled (HR) coils at its state-of-the-art Hot Strip Mills (HSM), at Vijayanagar (Karnataka) and Dolvi (Maharashtra). Vijayanagar HSM-I and HSM-2 with commissioned capacities of 3.2 MTPA and 5 MPTA respectively are equipped with sizing presses and an automatic line inspection facility which makes this facility the widest Hot Strip Mill in India.

Cold Rolled steel has an improved surface finish and tighter tolerances compared to hot rolled steel. It is commonly used for parts requiring cold forming, such as crimping, swaging or bending. It can also be used for Shafts, machinery parts, bolts, pinions, gears, as well as in the creation of furniture, appliances and other consumer goods.U001en Hot-Rolled Steel Sheets and CoilsHot-Rolled Steel Sheets and Coils meeting a variety of standards ranging from mild steels to high-tensile strength steels are available. Variable sizes of cut sheets, coils, and various surface finishes such as black finish, pickled finish and shot-blasted finish can be selected in accordance with your needs.
