cold rolled steel sheet production process flow diagram

The etched sample 1 exhibited predominantly a ferritic microstructure typical of a low-carbon cold-rolled steel sheet. However, a lot of metal flow and irregular grain formation near the defects was observed in this sample as shown in Fig. 3a and b at 500 × magnification. The reasons for so much metal flow around the cracks could be their …

Cold Rolled Carbon Steel Sheet. Cold Rolled Carbon Steel Sheet is produced by processing hot rolled material through a cold rolling process, reducing the thickness and enhancing the surface of the material. Applications of the material include commercial quality use, superdraw, drawing and forming, and enamelling.

continuous galvanizing line (CGL). This process consists of unwinding coils of cold rolled steel and feeding the sheet continuously through a cleaner, an annealing furnace, and then into a molten zinc bath at speeds up to 600 fpm [200 mpm]. As the steel exits the molten zinc bath, gas "knives" blow off the excess coating from the

Coil feeder. Cold roll forming consists of gradually and continuously forming a steel profile.

The process begins with a large coil of sheet metal that can be from 1 inch to 30 inches wide with a thickness of 0.012 inch to 0.2 inch. Before a coil can be loaded, it has to be prepared for the process. The above diagram represents each step of roll forming from the feeding of the coil to the cutoff and discharge at the end of the process.
