Cold Rolled Coil

The cold rolled steel coil is made of hot rolled steel coil.

The surface scale can be removed during pickled treatment and the finish mill. The cr steel coil is farther and thinner than the hot rolled coil. The main difference between the hot and cold rolled steel coil is the thickness, surface treatment, and the rolling temperature.

Main Advantages of Cold Rolled Steel Coil

Cold rolled steel/coils offer a variety of cold rolled steel sheet and coil products and value-added services to meet customer needs. HUARO's Cold Rolled Steel Coil service capabilities include slitting, shearing, blanking, leveling, degreasing and brushing, and metallurgical support.

Production Process of Cold Rolled Steel Coil

Cold rolled steel coil is rolled at room temperature, below its recrystallization temperature, which enables better control over finished product shape, thickness, dimensions and surface finish. The cold rolling process helps to obtain the CR coils from the cooling (in the cold rolling mill) of hot rolled pickled products (made from finest steel), which is reduced too much finer thickness with increased strength via strain hardening (up to almost 20%). The resulting CR coils are smaller as compared to the coils formed by the hot rolling process, and they are less ductile. They possess improved surface finish and tighter tolerances.
