CISDI was responsible for the process, plant design and partial nonstandard equipment design of the whole mill which stood for the typical heavy bar rolling line, targeting 800,000t/a output. The bar mill would produce Φ75mm~Φ450mm bars for machinery, automobile, and bloom for tube mill, as well as 150mmx150mm square billet, 400mmx400mm~600mmx600mm bloom and 400mm~600mmx100mm~200mm wide flat steel. The main steel grades as rolled would be quality carbon structural steel, alloy structural steel, anchor steel, bearing steel and tubular bloom. Compared with the other domestic heavy bar mills, this mill excelled in the biggest specification of products, the most complete coverage of products, rather complete configuration of equipment, and particularly, applying the most advanced technologies in its process, equipment and automation control.

 

As the organizer of engineering design of this heavy bar mill project, CISDI had, at the preliminary stage of execution, made serious surveys and analyses on the technological characteristics and product quality of heavy bar mills both at home and abroad. In so doing, CISDI made constructive suggestions on the product orientation and main equipment type sizing for Yonglian Steel. CISDI engineers had made concerted efforts during the last almost two years of construction engineering phase so as to ensure the project schedule and meet the customer’s requirements to the most degree.
