通过弹用燃烧合金颗粒制备实验,研究燃烧合金颗粒的形貌、制备难易程度、利用率与海绵锆中铁含量的关系。结果表明:铁含量直接影响燃烧合金颗粒的形貌、制备难易程度和利用率,在其他成分符合标准的前提下,铁含量越高,燃烧合金越不易破碎成所需的颗粒;铁含量较低时,燃烧合金容易破碎且颗粒形貌呈海绵状,制备的燃烧合金产品表面光洁、强度高。 Through the preparation of the combustion alloy particles, the morphology of the combustion alloy particles, the ease of preparation and the relationship between the utilization rate and the iron content in zirconia sponge were studied. The results show that the content of iron directly affects the morphology of the combustion alloy particles, the ease of preparation and the utilization ratio. Under the premise of the other components conforming to the standard, the higher the iron content, the harder the combustion alloy is broken into the desired particles; When low, the combustion alloy is easily broken and the particle morphology is sponge-like, the prepared combustion alloy product has a smooth surface and high strength.
