Abstract
Abstract A crucible holding a liquid raw material such as molten steel is enclosed in a pressurization chamber. A nozzle in contact with the raw material projects the raw material into a cooling fluid to form a solid finished product. A gasket formed of a material which is gas-tight and compatible with the raw material is mounted for contact with the raw material and has a portion extending away therefrom. The raw material facilitates a hot seal between (a) the portion of the gasket in contact therewith and (b) the crucible and nozzle. A cold seal is formed between (a) the portion of the gasket extending away from the raw material and (b) the pressurization chamber.
