摘　　要：通过检测4个厂家供应保护渣的化学成分、熔化温度、黏度和结晶率,并对其析晶能力进行了比较,发现目前所用的4种保护渣均为典型结晶性能渣,进一步结合连铸坯表面品质问题(如振痕不规则、凹陷和裂纹缺陷等),提出了保护渣性能的优化方案。并对提高保护渣的性能稳定性和改善铸坯品质,提出了进行保护渣系列化研究的建议。The crystallization abilities are compared by testing of mold flux for chemical position, melting temperature, viscosity and crystal ratio in four factories, the results show that the four mold flux are typical crystallization properties slag,in order to combine with surface quality of continuous casting slab such as irregular oscillation mark, depression, crack and so on, raise stablity properties of mold flux and improve surface quality of continuous casting slab, optimization projects of mold flux property and suggestions for series study of mold flux are put forward.
