Cold rolled steel sheeting This material is manufactured by re-rolling and cold reduction of hot rolled steel sheeting. The first step taken in the process is when a hot rolled steel coil is unwound and passed through rolls which flex the plating in such a manner as to break and fragment the mill scale. The plating is then pickled in an acid bath for the purpose of removing the mill scale completely, as well as rust and other extraneous matter which might be present. Thereafter, the material is washed to remove any trac…See more on cargohandbook.comHumidity / moisture: Relative humidity: < 40-50%sp.info How are three rolls used to bend steel?When rolling steel plate, the plate is placed between the upper and lower rollers, and the three cutting points that are exposed to the metal sheet by three rolls can make the plate bend into a curved or closed circle.See all results for this questionsp.info How to calculate the force to bend a steel bar?In general the bending equation is S = My/I where S is stress (you will use the material's yield stress here), M is the bending moment (force applied times distance from the bend), y is the distance from the neutral axis (in your case this will be half of the bar's thickness) and I is the moment of inertia for the bar shape. Click to expand...See all results for this questionsp.info What happens to the straight edge of a roll bending plate?When the plate is rolled, each end of the plate has a length can be bent due to none contact with the upper roller, which is called residual straight edge. During symmetrical bending, the remaining straight edge is usually about half of the center distance of the lower roller, and it is also related to plate thickness.See all results for this question
