| 摘要 |
The present invention relates to a method and an apparatus for production of cavity-free cast explosive charges of meltable crystalline explosives. According to the invention the formation of solidification cavities in the explosive is prevented by keeping the upper part of the casting warm with the aid of the casting funnel (3) which is used during the casting and which contains a heat-retaining medium contained within a chamber formed in the casting funnel so as to be in heat- communicating relationship with the upper part of the mould into which the explosive is cast. <IMAGE> |
