The results of microscope,SEM,TEM and EDS revealed that the particles precipitated in the pre- austenite grain boundaries will result in network cracks under sufficient stress such as thermal stress,bending and straightening stress due to uneven cooling of strand surface.
采用金相显微镜、SEM、TEM和EDS等方法,分析了因连铸板坯表面冷却不均匀引起γ→α反复相变导致碳氮化物在晶界析出,并在外力(热应力、弯曲矫直应力等)作用下产生沿晶界开裂的网状裂纹的形成机理,以及钢中[C]、Mn/S、[Al]、[V]、连铸冷却强度等对连铸板坯网状裂纹的形成和扩展的影响。

For the surface network cracks in 200mm thickness slabs for pipeline and veicle frame,it is found that the carbon content,Mn/S ratio and Al,Ti,V,Nb alloy additions and continuous caster conditions are attributa- ble to the formation and propagation of surface and subsurface network cracks.
统计分析了攀钢所产管线钢、梁板钢等200mm×1300mm连铸坯表层网状裂纹的影响因素;发现钢中碳、锰硫比、合金元素(Al,Ti,V)、连铸机设备和浇注状况对其形成和扩展都有重要影响。
