Soluble ceramic core, preparation method and application
The invention relates to a soluble ceramic core, a preparation method and application, and belongs to the related technical field of rapid casting. The preparation method disclosed by the invention comprises the following steps: (1) uniformly mixing ceramic powder and soluble salt, printing a ceramic core initial blank by using a micro-droplet jet bonding forming process, and curing, infiltrating and drying to obtain a ceramic core green body; and (2) sintering the ceramic body in a high-temperature sintering furnace, and cooling along with the furnace to obtain the soluble ceramic core. According to the preparation method, the ceramic powder and the soluble salt are uniformly mixed, the soluble ceramic core is prepared by applying a micro-droplet spraying bonding forming process, the operation is simple, the production efficiency is high, the cost is low, the preparation method is suitable for forming a large-scale ceramic core with a complex structure, and the prepared ceramic core has good solubility and is very convenient to remove from a casting after pouring is finished.
本发明涉及一种可溶性陶瓷芯、制备方法与应用，属于快速铸造相关技术领域。本发明的制备方法包括以下步骤：(1)将陶瓷粉和可溶性盐混合均匀，运用微滴喷射粘结成型工艺打印出陶瓷芯初坯，经过固化、浸渗以及烘干后得到陶瓷芯坯体；(2)将陶瓷坯体放入高温烧结炉中进行烧结，随炉冷却后得到可溶性陶瓷芯。本发明通过将陶瓷粉和可溶性盐混合均匀，运用微滴喷射粘结成型工艺制备可溶性陶瓷芯，操作简单、生产效率高、成本低，适合成型大型复杂结构陶瓷芯，本发明制备的陶瓷芯具有良好的可溶性，在浇注结束后十分便于从铸件中去除。
