The special steel bar (coil) production line is featured with the composite hot rolling function of fully continuous bars and large coils. Its main equipment is sourced from Italian DANlELl, German KOCKS, SIMENS and other companies. The main drives of all rolling mills are supported by the DC frequency conversion speed regulation technology. The whole line is automatically controlled by a computer system, providing a system guarantee for the reliable operation and good production management of the rolling equipment. The German KOCKS rolling mill of the sizing unit of this production line features the highest dimensional accuracy in producing round bars in the world. The accuracy of the finished round bar produced can reach or even exceed 1/4-1/5DlN1013. Besides, it can realize free-size rolling, and hot rolling process technology. The whole line operates under digital control and powered by the online diameter measurement technology, whole-line controlled rolling and cooling technology, and online flaw detection technology.  It can produce straight bars with the specification ranging from ?16mm to ?90mm and large coils with the specification ranging from ?14mm to ?42mm. Straight bar products mainly include bearing steel, spring steel, alloy steel, non-quenched and tempered steel, carbon structural steel, free-cutting steel and other products. Large coil products mainly comprise cold heading steel, high-quality carbon structural steel, alloyed structural steel, bearing steel, free-cutting steel, spring steel, etc. The production line is a bar and large coil composite one ranking among the top class both domestically and internationally. Products from it are characterized by a uniform internal structure, good surface quality, high dimensional accuracy and complete product categories.
