摘要： An apparatus for casting a metal foam article comprises a crucible for containing the molten metal, a gas injection nozzle located above the level of the molten metal when at the neutral level, and a mould having a mould cavity of the shape of the article. The apparatus includes a means for raising the level of the molten metal above the gas injection nozzle for generating the foam. A method for casting the foam article comprises maintaining the level of the molten metal below the gas injection nozzle until foaming is desired, raising the level of the molten metal above the gas injection nozzle and injecting a gas into the molten metal for generating the metal foam. The method also comprises directing the foam into the mould and cooling the foam to form the foam article. The apparatus may be constructed of separable modules thereby allowing the process to be tailored to meet specific requirements.
摘要翻译：一种用于铸造金属泡沫制品的设备包括用于容纳熔融金属的坩埚，当处于中性水平时位于熔融金属水平面上方的气体注入喷嘴以及具有制品形状的模腔的模具。该设备包括用于提高气体喷射喷嘴上方的熔融金属液位以产生泡沫的装置。用于铸造泡沫制品的方法包括将熔融金属的水平保持在气体喷嘴下方直至期望发泡，提高气体喷嘴上方的熔融金属的高度并将气体喷射到熔融金属中以产生金属泡沫。该方法还包括引导泡沫进入模具并冷却泡沫以形成泡沫制品。该设备可以由可分离的模块构成，从而允许该过程被定制以满足特定的要求。

摘要翻译：用于铸造金属泡沫制品的装置包括用于容纳熔融金属的坩埚，当处于中间位置时位于熔融金属的高度上方的气体注入喷嘴以及具有制品形状的模腔的模具。该装置包括用于提高用于产生泡沫的气体注入喷嘴上方的熔融金属的高度的装置。用于铸造泡沫制品的方法包括将熔融金属的水平保持在气体注入喷嘴下方直到发泡为止，提高气体注入喷嘴上方的熔融金属的水平并将气体注入到熔融金属中以产生金属泡沫。该方法还包括将泡沫引导到模具中并冷却泡沫以形成泡沫制品。该装置可以由可分离的模块构成，从而允许该过程被定制以满足特定要求。
