摘要
沙钢集团于2006年建成年产能180万t/a现代化宽厚板厂。主要工艺包括采用8段步进粱式加热炉、带液压AGC和WRB的φ1210mm×5050mm工作辊、带油膜轴承φ300mm×4900mm支承辊的高刚度4辊轧机。最大轧制力100MN,最大切断力矩2×4925kNm;MULPIC装置ACC、DQ和DQ+自回火,得到针状铁素体、下贝氏体及岛状马氏体相变组织而改善铜板组织性能;采用强力热矫机、步进量冷床、滚切双边剪、剖分剪和定尺剪及强力冷矫机;LOI无氧化辐射管辊底炉热处理设施。全线采用L1-L3、ERP和MES系统,该宽厚板厂装备达到当今国际先进水平。
Shagang Group in 2006 built a modem heavy plate works with an annual output of 1.8 million ton. Major technology included 8 segments walking beam heating furnace, high stiff four roller mill with φ1210mm×5050mm work roll with the hydraulic AC, C and WRB and φ2300mm×4900mm high roller with kelmet, MULPIC device ACC, DQ DQ tempering, a powerful heat straightening machine, walking beam cooling bed, Hob bilateral shear, subdivision shear, dividing shear, high - strength cold leveler, LOI no oxidation radiation tube roller bottom furnace heat treatment facilities . All lines use L1-L3, ERP and MES system, and the equipment of the heavy plate Plant reach the current international advanced level.
