通过获得现场不同位置及由结晶器渣膜热流模拟仪获得不同时刻的渣膜,对比分析了渣膜的厚度、结晶率、晶体的分布、大小、类型.结果表明,结晶器渣膜热流模拟仪铜探头浸入45s时获得的实验室渣膜与现场弯月面附近45s的现场渣膜厚度和结晶率相当;现场渣膜随位置在晶体分布上演变规律与实验室渣膜随时间的演变类似;现场渣膜与实验室渣膜的晶体的类型相同,但是晶体大小还存在差异.因此,可以通过结晶器渣膜热流模拟仪方便、有效的模拟实际结晶器内保护渣渣膜的结晶行为.
The slag film at different times was obtained by different positions in the field and the crystallizer slag heat flux simulator was used to analyze the thickness, the crystallization rate, the distribution, the size and the type of the slag film.The results show that the crystallizer slag film heat flow simulator The immersion time of copper probe in 45s was similar to that of 45s in the field near the on-site meniscus. The evolution of on-site slag distribution along the crystal distribution was similar to that of laboratory slag film over time. However, the size of the crystal is still different, so the crystallization behavior of the slag film in the mold can be simulated conveniently and effectively by the mold slag film heat flow simulator.
