在西德,每年约有10%的钢产量是含碳量0.06～1%;的线材产品。对于低碳线材,研制讣划的主要目的在于改善塑性、焊接性能和机械性能;蚶于中碳和高碳线材,在于从热轧状态采用有效的冷却设备和各种冷却方法,以获得更好的机械性能。拉伸载荷的高强度极限,较高总压缩牢的显微组织上必要的细晶粒层状珠光体和微量先共析铁素体,是线材散圈在输送带上或竖井中冷却得到的。这种冷却的方式有斯太尔摩法(stelmor)、斯罗曼法(Schloemann)或台玛克野瓦太法(Demag-yawata process)。
In West Germany, about 10% of the annual steel production is 0.06 ~ 1% carbon content; wire products. For low-carbon wire rod, the main purpose of obituary development is to improve the plasticity, weldability and mechanical properties; 蚶 in the carbon and high carbon wire, from the hot state using effective cooling equipment and cooling methods to get better Mechanical properties. Tensile load of high strength limit, the higher total compression firmly on the microstructure of the fine grain layered pearlite and trace pro-eutectoid ferrite, is the wire scattered in the conveyor belt or shaft cooling obtained . This cooling can be done in the form of stelmor, Schloemann or Demag-yawata process.
