By means of pressureless sintering process,the zirconia ceramic materials were prepared using calcia partially stabilized zirconia and monoclinic zirconia as raw materials,Y2O3 and CeO2 powder as composite stabilizer,PVA as binder.The effects of monoclinic zirconia grain size distribution,molding pressure and granulation on the sintering,mechanical strength,thermal shock resistance and phase composition of the specimens sintered at 1700℃ and 1720℃ for 3h in an air atmosphere were investigated.The results indicate that zirconia materials with good thermal shock resistance can be produced by this method.At the same time,monoclinic zirconia powder is finer,and the more contributions can be made to stability and densification of zirconia because of the transformation of monoclinic zirconia to cubic zirconia.

通过利用喷吹法和四辊离心法制备矿渣棉,研究在不同制备方法条件下,矿渣棉其化学稳定性、表观特征、含水率及渣球含量与酸度系数之间的关系.结果表明:在满足成纤要求的前提下,高炉渣酸度系数应控制在1.2～1.4;利用喷吹工艺制备的矿渣棉直径较细,含水率较低,成纤率较低,渣球含量较高纤维质量较差;相对于喷吹工艺离心法制备的矿渣棉直径相对较粗,含水率大,渣球含量较少,成纤率较高,纤维质量较好.

常规控制轧制受三阶段轧制温度的限制,生产效率受影响,也无法抑制再结晶奥氏体晶粒长大.高效控制轧制是将轧制过程的材料温度、应变与材料力学行为实时耦合的新工艺方法,细化奥氏体组织的同时,缩短控轧周期.依据Q345钢的高温性能特点,采用有限元法对高效控制轧制过程进行了模拟,并用实验室轧制模拟以及工业中厚板轧机试验的方法对模拟结果进行验证.研究结果表明:高效控制轧制有利于增加坯料心部应变量,最大增加了61
本文介绍S型转炉导渣技术在转炉炼钢上的应用,S型转炉导渣法是变堵挡为疏导,在出钢快要结束时启动导渣装置,驱动导渣槽至准备位置,结合镭目转炉下渣检测技术,在下渣时刻导渣槽立即由准备位置伸向出钢口,把原先流向大包的渣通过导渣槽导流至渣盆或其他适当的地方,待完成导渣后迅速地回到初始位置.导渣法可有效防止渣进入大包,实现大包渣层薄、提高钢水洁净度的目的.

加钛护炉是一种常用的高炉护炉手段，目前护炉料来源主要有两种：一种是含钛球团，另一种是含钛块矿。本文对一种澳洲含钛精矿粉毅星精粉进行了实验室研究,包括化学成分全分析、烧结基础特性检测、扫描电镜分析、X衍射物相分析、成球性检测、烧结杯试验等。该矿粉粒度偏细(＜200目超过65％),钛含量高(TiO2含量3.69％),并且在受热后易产生刺激性气味。研究发现,毅星精粉中的主要矿物为磁铁矿(Fe3O4)和氧
本文通过调整热轧卷取温度制备了三卷不同热轧态组织的42CrMo钢,采用相同的工艺对三卷试验钢进行球化退火,研究了不同热轧态组织对合金结构钢42CrMo球化率的影响。结果表明:(1)卷取温度从720℃下降到580℃,42CrMo钢热轧态组织依次为珠光体、伪珠光体、贝氏体组织,同时钢中先析出铁素体的量逐步减少。(2)原始组织越接近平衡态,球状碳化物越难以形成。
