The purpose of finishing rolling is to adjust the thickness and width of a coil to the specified dimensions and to produce a smooth surface and shape at the desired finishing temperature appropriate for its intended use. Order Information 21 1 . Powered by state-of-the-art facility and technology, POSCO operates a totally computerized, end-to-end full automatic production system. In the process of rolling out high-temperature hot rolled coil steel (eg 780 o C) if you want to roll out cold rolled steel coil (Cold roll coil-CRC), reduce that temperature to the right temperature (eg: 480 o C) and continue rolling down the thickness. Pickling. A4.1 - Hot rolled coil - Drawing & Forming steel grades Steel slabs, which are produced in a continuous casting plant, are first conditioned in a reheating furnace before being transferred to the steel rolling works. Hot Rolled Coil and cold rolled coil are the two distinct prefabricated steel widely used among the steels that come into the market for various applications like infrastructure, vehicles, appliances, wind turbines, etc. The concept is similar to the rolling of dough.
