一种微波固化水溶盐芯的快速成形方法
摘要：
本发明的一种微波固化水溶盐芯的快速成形方法，属于铸造技术领域。本发明的方法步骤为S100、无机盐的预处理；S200、配置喷射液；S300、微滴喷射成形；S400、间歇式微波固化；S500、浸润或喷淋无机盐溶液；S600、二次间歇式微波固化；S700、烧结。本发明通过对盐芯微波硬化预成型后，再对盐芯进行无机盐溶液浸润、二次微波固化以及烧结，由于无机盐溶液的润湿性能极强，可以充分润湿填充预成型盐芯的孔隙，并在二次微波固化过程中结晶析出无机盐，显著提高了盐芯的强度。
摘要（英）：

The invention discloses a rapid forming method of a microwave-cured water-soluble salt core, and belongs to the technical field of casting. The method comprises the following steps that S100, inorganic salt is pretreated; S200, a jetting liquid is prepared; S300, micro-drop injection moulding is performed; S400, intermittent microwave curing is performed; and S500, the salt core is infiltrated orsprayed with an inorganic salt solution; S600, secondary intermittent microwave curing is carried out; and S700, sintering is carried out. According to the method, the salt core is subjected to the microwave curing and the pre-forming, and then the salt core is soaked in the inorganic salt solution and is subjected to the secondary microwave curing and the sintering; due to the fact that the wettability of the inorganic salt solution is extremely high, the pores of the preformed salt core can be fully wetted and filled, the inorganic salt is crystallized and separated out in the secondary microwave curing process, and the strength of the salt core is remarkably improved.
