一、前言关于连铸坯表面振动波纹的形成机理,已提出若干模型。第一个模型是在负滑脱期间,弯月面处的薄坯壳被熔渣压弯。第二个模型是在正滑脱转间,钢水流动越过坯壳前沿。第三个模型是受界面张力影响的弯月面的形状被凝固。也报导了在振动波纹处楔状
I. INTRODUCTION Several models have been proposed regarding the formation mechanism of vibration ripples on the surface of slab. The first model is that during the negative slip, the thin shell at the meniscus is crimped by the slag. The second model is the slippery turn, the flow of molten steel across the front of the shell. The third model is that the shape of the meniscus affected by interfacial tension is solidified. It also reported wedges at the vibration ripples
