摘　　要：粘结漏钢具有残留坯壳外表面振痕紊乱、坯壳厚度从上向下逐渐变薄和坯壳厚度不均匀系数大的特点。粘结漏钢往往与所使用的结晶器保护渣性能有关。阐述了粘结漏钢与保护渣的关系 ,并提出了一些防止漏钢的措施。Molten steel leakage by binding has the defects including disordered vibration mark on outer surface of surviving billet shell, thickness of billet shell gradually getting thinner from up to down and large uneven coefficient of billet shell thickness. Molten steel leakage by binding is often related to the properties of mould powder. This paper explains the relationship between them and puts forward some measurements to prevent molten steel leakage.
