信息来源:本站浏览次数:13666

特殊钢大棒材生产线总体工艺由意大利达涅利公司设计。加热炉、开坯机、钢坯火焰清理机、连轧机、飞剪、kocks、组合锯、砂轮锯等关键核心设备和部分控制系统从法国斯坦因公司、意大利达涅利公司、美国L-TEC公司、德国kocks公司以及奥地利布朗公司引进;全线采用全数字交流变频传动系统。轧线配置及轧机选型:轧线采用半连轧模式,粗轧机采用1150mm二辊闭口可逆式轧机,精轧机采用8+4架短应力线式轧机,平立交替布置,定尺锯采用4台组合热锯及及布朗锯锯切。该生产线采用在线测径技术、无损探伤技术、控轧控冷技术、在线火焰清理技术、热装热送技术,ø50mm~ø160mm配备德国KOCKS减定径轧机,可实现自由尺寸轧制。产品规格:圆钢ø50mm~ø300mm;方钢100mmx100mm~180mmx180mm;轧制用坯195mmx195mm~360mmx360mm。着力打造以轴承钢、齿轮钢、合金结构钢、优质碳素结构钢、非调质钢、高压锅炉管钢、锚链钢等产品为主的特殊钢生产基地,特钢产品覆盖汽车及工程机械、石油化工、风力发电、铁路及轨道交通等行业。该生产线生产灵活,适应性强,产品精度高,组织性能稳定,锯切质量高,技术装备、产品质量及自动化水平均达到了国际先进水平。

The overall process of the special steel large bar production line was designed by Danieli Metallurgical Equipment Co., Ltd., a company based in Italy. Key core equipment such as heating furnaces, breakdown mills, steel billet flame cleaning machines, continuous rolling mills, flying shears, KOCKS, combination saws, and grinding saws, and some control systems are imported from companies such as Fives Stein in France, Danieli in Italy, L-TEC in the United States, KOCKS in Germany, and Braun in Austria. The whole line runs with a full-digital AC variable frequency drive system. In terms of the configuration of the rolling line and the selection of rolling mills, the rolling line runs in a semi-continuous rolling mode, with a ø1,150mm two-high reversible rolling mill for the cogging mill and an 8+4 short-stress-path rolling mill for the finishing rolling; the stands are arranged alternately horizontally and vertically. The fixed-length saws consist of 4 combination hot saws and Braun saws for cutting. The production line employs the online diameter measurement technology, non-destructive testing technology, controlled rolling and cooling technology, online flame cleaning technology, and hot charging and hot delivery technology. Equipped with German KOCKS reducing and sizing rolling mills capable of achieving free size rolling ranging from ø50mm to ø160mm.  It mainly produces round steel with the specification ranging from ø50mm to ø300mm, square steel with the specification ranging from 100mm×100mm to 180mm×180mm, and rolling billets with the specification ranging from 195mm×195mm to 360mm×360mm. The company focuses on building a special steel production base primarily for bearing steel, gear steel, alloyed structural steel, high-quality carbon structural steel, non-quenched and tempered steel, high-pressure boiler tube steel, and anchor steel. Special steel products cover industries such as automobiles and engineering machinery, petrochemicals, wind power generation, railways, and rail transportation. The production line is flexible and highly adaptable, with high product accuracy, stable organizational performance and high sawing quality. Its technical equipment, product quality, and automation level have all reached international advanced standards.
