U003en Cold-Rolled Steel Sheets and Coils

2020-4-9 · From Cold-Rolling to Annealing. Pickled coils are rolled to the specified thickness . by cold rolling. The Cold-Rolled Steel Sheets and Coils have their crystal grains enlarged in the rolling direction, making the texture hardened and brittle. In the annealing process, the coils are continuously heated in reductive atmospheric gas to form uniform

Quality Improvement in Finished Cold Rolled

2016-9-9 · Practically the all defects in cold rolling inspected before dispatching the material to the customer at skin pass mill. R&C Inspection wings generally focused over four "S" i.e. Shape, Size, Surface and Safety during their inspection. Cold rolling improves the surface finish and holds tighter tolerances. This will certainly affect the quality

2020-9-30 · In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change in its cross-sectional area.. The types of rolls used in rolling mills are depended upon the shape, size and the gap between the rolls and their contour. Because of workability and limitations in equipment, rolling …

2019-2-4 · 1.7 Rolling mill control: Production of continuous sheets and strips is one of the attractive features of modern rolling mills. However, control of sheet thickness and cross-section is a real challenge. In order to continuously monitor the thickness of sheets rolled, x-ray or gamma ray sensors are used.
