高强度机械用钢生产线

特殊钢棒（卷）生产线是一条全连续式棒材和大盘卷复合热轧生产线，主要设备从意大利DANlELl、德国KOCKS、SIMENS等公司引进，全部轧机主传动采用直流变频调速技术，全线由计算机系统自动控制，为轧线设备的可靠运行和生产管理提供了系统保证。该生产线减定径机组德国KOCKS轧机是世界上生产圆钢尺寸精度最高的轧机，轧出的成品圆钢精度等级能达到甚至高于1/4~1/5DlN1013标准，并且可以实现自由尺寸轧制，可实现热机轧制工艺技术，全线的数字化控制和在线测径技术、全线的控轧控冷技术、在线探伤技术。产品规格：ø16mm～ø90mm直条棒材和ø14mm～ø42mm大盘卷。直棒产品主要以轴承钢、弹簧钢、合结钢、非调质钢、碳素结构钢、易切削钢等产品为主。大盘卷产品主要以冷镦钢、优质碳素结构钢、合金结构钢、轴承钢、易切削钢、弹簧钢等为主，是一条具有国内一流、国际领先水平的棒材、大盘卷复合生产线，产品具有内部组织均匀、表面质量好、尺寸精度高、产品品类全等特点。

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 ø16mm to ø90mm and large coils with the specification ranging from ø14mm to ø42mm. 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.
