January 30, 2011, CISDI got a successful load test for the 800,000t/a quality light bar mill under her design for Handan Steel Melting & Rolling Rebuild project. The final round bar Ф70.0mm was rolled through feeding the 150mmx150mm billet and rolling by 4-stand roughing mill and 2-stand intermediate mill. The 2-roll reducing and sizing mill is imported to realize high accuracy of final product size and simplify the roll configuration in producing Ф16.0~90.0mm quality carbon steel, alloyed structural steel, cold heading steel, spring steel, bearing steel and other quality and special steel bars.
