Introduction to Manufacturing Process

Billet Conditioning: This process is intended for checking the surface quality of billet and removing any defects.

Rolling: The 4-high reversible finishing mill with the maximum load of 7000 tons minimizes internal defects even inly thick plates.

Pre-Treatment Process: Some rolling oil and other contaminants remain on the surface of cold rolled steel sheets following processing.

Uncoiling and Straightening: We need to have our carefully-selected steel plates of top quality straightened using the straightening machine to make them flat and straight, which lays a solid foundation for subsequent forming and welding.

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..

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.

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.

Pickling: 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.
