摘要
针对如何有效研究熔铸装药药柱气孔疵病问题,提出采用注射器向熔铸装药药柱内预置气孔的方法。通过理论分析、仿真计算、工艺试验及应用验证,在精准控制气体注入时机时,可稳定可靠制备含气孔疵病的装药药柱,注入气体的体积与形成气孔体积相当。结果表明,制备的含气孔疵病装药药柱可作为装药抗过载安定性试验的标准试验件,对开展相关领域研究有一定指导意义。
In view of how to effectively study the blowhole defect of the fusion-cast charge,a method of presetting blowhole into the fusion-cast charge with an injector is proposed.Through theoretical analysis,simulation calculation,process test and application verification,the charge column with porosity defects can be prepared stably and reliably when the gas injection timing is accurately controlled,and the volume of the injected gas is equivalent to the volume of the formed pores.The results show that the prepared charge column with porosity defects can be used as the standard test piece for the charge overloading stability test.It has a certain guiding significance for carrying out research in related fields.
