摘　　要：针对传热与润滑两者之间的矛盾,不同钢种对保护渣及渣膜性能的要求不同,适宜的保护渣物质组成是熔渣结晶和渣膜形成的关键,因此,掌握各组分对结晶性能的影响规律,可以设计出保护渣合理的物质组成,实现控制渣膜结构以满足不同钢种对润滑与传热的要求。主要综述了保护渣中各物质组成对结晶温度、析晶速率、结晶矿相及结晶率等性能影响的研究成果,并指出了目前研究的局限性,同时就继续深入研究保护渣物质组成及渣膜的结晶性能提出了几点建议。In light of the contradiction between lubricity requisition on the powder＇s performance. Because proper and heat conductivity, The different steels have different ingredients are the key of flux film＇ s crystallization and formation ,only understand how each components affect crystallizing properties can we develop powder to ensure film＇ s structure can be controled to meet the demand of lubricity and heat conductivity for different steels. The re- search results about the influence of each component on crystallization temperature, crystallization speed, mineralogi- cal phase and crystal rate are summarized. Finally, The research localization and some advices for the study of Ingre- dients and crystallizing properties of mold flux are pointed out.
