The first part incorporating a second cold-rolling mill and an annealing and pickling line is scheduled to go into operation by autumn of 2004, adding 94,500 tons to the plant`s annual capacity. The final part of the cold-rolling mill will increase the capacity to 268,000 tons per year by the end of 2005 according to the new schedule.
Nov 09, 2013· During cold rolling process the reduction in thickness is due to plastic deformation which occurs by means of dislocation movement. Steel gets hardened because of the buildup of these dislocations. These dislocations reduce the ductility of cold rolled steel making it useless for forming operation.
There is almost no end to the uses of high-grade steel strip in today's world. They include everything from aircraft to beverage cans. That explains why we design our cold rolling mills to be just as versatile. What's important to you are not only high flexibility and product quality, but also sustained, cost-effective operation of your plants.

Jul 08, 2019· Temper / Skin Pass Mills The device uses skin pass rolling to improve the mechanical properties and surface texture, and improve flatness, in order to form materials such as hot-rolled steel sheets, cold-rolled steel sheets, stainless steel plates, and aluminum plates into final products.
Cold rolling cannot reduce the thickness of a workpiece as much as hot rolling in a single pass. Cold-rolled sheets and strips come in various conditions: full-hard, half-hard, quarter-hard, and skin-rolled. Full-hard rolling reduces the thickness by 50%, while the others involve less of a reduction.
During warm rolling an abrupt drop in MFS occurs in the fourth pass; this appears to be associated with the start of the austenite-to-ferrite transformation. The temperature in this pass, 840°C, is near the Ar3 temperature, 855°C, calculated using the equation of Blás et al., 1989. Microstruture and properties
Tags Pickle Lines, Rolling Mills; Temper Pass or Skin Pass Rolling. Material can be reduced accurately while skin passing. Hot rolled steel coming from a steel mill or pickle line may need to be reduced 1% to 2% in thickness. This can be done on a coil-to-coil temper pass mill .
The first two phases of the investment are currently in operation, including a hot annealing line, two cold rolling mills and a cold annealing line, as well as two skin-pass mills and several finishing lines, with a capacity of production of 400,000 tons/year and a cumulative investment of more than 600 million dollars.
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
