1. Preliminary Annealing: During the preliminary annealing process, a scale which may have formed on the hot rolled steel is removed as delayed passing through scale breaker and a hydrochloric acid bath. This initial heat treatment process improves the cold rolling properties of steel as well as its magnetic properties.2. Cold Rolling: In order to obtain specific...

1. Reheating: Hot rolled coils pass through a pickling line, where scale breaker machines and hydrochloric acid solutions are used to remove any surface scale and/or oxide film that which causes surface flaws during the final stage of cold rolled steel processing.2. Roughing: In this process, slabs whose surface scale share has been removed are made into...

1. Steel Making: Steelmaking has the greatest impact on the quality and cost of steel products. We has state-of-the-art AOD, VOD and continuous casting facilities..2. Hot Rolling: Slabs made in the steelmaking plant are rolled into black coils of highly refined thickness and shape before being made into white coils to the needs of customers through heat...
