本研究的目的是寻找制造重要铸件的陶瓷型芯的成分和工艺。为保证陶瓷壳型最佳的使用性能,可使用综合粘结剂—耐热有机硅清漆及细弥散碳化硅。这时在焙烧过程中在电熔刚玉颗粒上形成高致密性的细纤维膜状粘结剂。使用结晶石英粉和碳酸钙粉作为粘结剂时,电熔刚玉颗粒被与其烧结的和自身间烧结的石英颗粒所粘结,石英颗粒又形成特殊的骨架而保证了材料强度。
The purpose of this study was to find out the composition and process of the ceramic core from which important castings are made. To ensure the best performance of ceramic shell type, the use of integrated adhesives - heat-resistant silicone varnish and fine dispersion of silicon carbide. At this time in the firing process in the fused corundum particles to form high-density fine fiber membrane binder. When using crystal quartz powder and calcium carbonate powder as the binder, the fused corundum particles are bonded with the sintered quartz particles themselves and the quartz particles form a special skeleton to ensure the material strength.
