3 Brief Introduction Hung Li Steel Corporation (HLS), a wholly owned subsidiary of Chung Hung Steel Corporation (CHS), was established in August The registered capital of HLS is 3 Billion NTD and the factory covers hectares located in Lin-Hai Industrial District, Kaohsiung. The major products include hot-dip galvanized steel coils with different strength that manufactured from hot-rolled or cold-rolled coils, mainly supplied by Chung Hung Steel and China Steel Corporation. Since 4 th quarter 2010, HLS is entrusted to manufacture hot-rolled pickled and oiled coil (PO) for CHS and China Steel Corporation (CSC). To be the leader of high grade of HGI and PO products, is the vision of HLS. Moreover, we pursue the development of niche products to enhance our competitiveness and achieve the win - win situation between customer and HLS. 1

4 Manufacturing Process of CGL Hot-Rolled Galvanized products (HGI) are mainly manufactured by this process. For Cold-Rolled Galvanizing products (CGI), the Cold-Rolling is implemented by CHS. Coating treatment on roll surface The surface of all rolls in the furnace has coating treatment to avoid contaminants and improve the surface quality of strip. Non-oxidizing furnace Mini spangle Entry crop shear Welder Rinse tanks Pickling tanks Entry Uncoiler Entry loop car Zinc pot KOHLER adjustable air knife system The coating weight detected by X-ray will be feed-back to KOHLER system which can adjust the angle or pressure of air knife to obtain proper coating. 2

5 Hot rolled coils may go to CPL pickling before CGL process to meet customer special request, e.g., cut edge or severe flatness or surface requirements.

13 Manufacturing Process of CPL Tension Leveler (Scale Breaker) Wet type tension leveler could break the scale of strip surface before pickling that contribute very good flatness and cleanness for Pickled and Oiled products. Tension Leveler Flash Butt Welder Pickling and rinsing Hot Rolled Coil X' Ray Gauge Inspection EPC Side Trimmer Width Gauge Oiling Hot Rolled P/ O Coil DCS Continuous Acid Analysis System DCS continuous acid analysis system can automatically control about acid concentration, temperature, flow rate to diminish all related consumption of acid, steam, water etc. The system also can approach the higher level of environment and energy saving. Loop Car and Roll Blade Mechanism To ensure CPL can operate continuously, loop cars built in entry section, side trim section and exit section. To prevent from roll marks on the strip surface, dusts and scale powders on the roll surface could be removed through 10 sets of roll blade mechanisms. 11
