Spray-runner
A long main runner, having sprays that connect with the mould. If one ingate be insufficient to distribute the metal equally hot to all parts of the mould, it is possible by this means to introduce the metal at numerous other parts, without any increase of the number of ladles employed, by simply extending the main channel, and connecting with the mould at such parts; taking care that the size of the channel be proportionate to the sprays flowing out from it. By this method thin plates are successfully run from one or two ladles of hot metal, which otherwise would require four or even six. For work that is rolled over, these sprays are best when formed by a pattern and set against the pattern before ramming the nowel. See RUNNER; GATE.
