研究了无碳耐火材料悬浮液压力注浆成型的可能性，该悬浮液具有优化的粒度分布和毫米范围内的颗粒直径。用新研制的落球粘度计进行实验，考察了滑移流动能力。通过抛光样品上的显微镜和计算机断层扫描来确定分离。采用滤饼过滤的基本特性来突出对压力注浆成型过程的重要影响。在实验室试验的基础上，提出了用商业压力注浆成型机进行的放大试验的结果，该压力注浆成型机被改造成用于含有粗颗粒的悬浮液。
The possibility of pressure slip casting of carbon free refractory suspensions with optimized grain size distributions and particle diameters in the range of millimeters is investigated. The slip flow ability is examined by conducting experiments with a newly developed falling sphere viscometer. Segregation is determined by microscopy on polished samples and computer tomography. Fundamental characteristics of cake filtration are adopted to highlight the significant influences on the pressure slip casting process. Based on the laboratory experiments the results of scale up trails are presented which were conducted with a commercial pressure slip casting machine, remodeled for suspensions containing coarse grains.
