Laboratory investigation on formation of inclusion in Ti-Al complex deoxidized C-Mn steel was carried.The results are as follows : when Al content in steel is very low ( [ Al] = 0.000 5%),0.003% < [ Ti] < 0.007%,the inclusions is the Al2O3-SiO2 - MnO-TiOx composite inclusion;[ Ti];0.OO9%,the inclusion is Tio in the steel.When [ Ti] = 0.005%,[ Al] < 0.001%.the inclusions is the A12O3-SiO2 - MnO-TiOx composite inclusion;[ Al] > 0.006%,inclusions would be pure A12O3 The experimental results agree with the thermodynamics conclusions.

为了控制过共析钢中TiN的析出,要同时降低钢水中的钛含量及氮含量。生产实践表明，为控制碳质量分数为0.80％～0.95％的钢种中的TiN夹杂，需要进一步降低凝固前沿液相中氮钛浓度积，当钢中钛的质量分数控制在≤0.0004％,氮的质量分数控制在≤0.004％能显著降低甚至杜绝过共析钢中TiN的析出。
实际连铸生产条件下，铸坯在结晶器内的凝固伴随着复杂的流动与传热等过程的交互作用和相互影响，研究结晶器内钢液的流动状态和传热行为对设计和优化连铸工艺具有指导意义。建立了基于结晶器温度实测数据的板坯连铸结晶器传热反问题的数学模型和基于大涡模拟湍流模型的结晶器内流场与温度场耦合计算的数学模型。对于反传热问题采用二维层片法进行求解，模拟分析了结晶器温度和热流的分布状况,确定了结晶器与铸坯之间的热流密度.然

在脱硫扒渣的过程中,不同批次铁水包扒出的铁水会相互渗透,导致渣铁凝固结成大块,难以破碎,针对这一问题,宝钢集团新疆八一钢铁股份公司第二炼钢厂开发了一种使用炼钢系统自产废料制备脱硫渣阻断剂,使用该阻断剂后不仅降低了脱硫渣的加工处理难度,渣铁回收率达到92％以上,而且减轻了环境污染,予以浅述。
在连铸结晶器保护渣成分范围内制备了CaO-SiO2-Al2O3-Na2O-CaF2五元水淬渣样,在渣样化学成分和Raman光谱检测分析的基础上,计算了熔体结构单元含量,进而讨论了 熔体碱度和Al2O3含量对熔体聚合程度的影响和铝离子的存在形式.结果表明,随着碱度的升高,熔体的NOB/T值增大,聚合程度降低,随着Al2O3含量的升高,熔体的NOB/T值减小,聚合程度升高.熔体中的硅离子主要以Q0\Q
