单词	tuyère
释义	tuyère /twiːˈjɛː / /tuːˈjɛː/ noun A nozzle through which air is forced into a smelter, furnace, or forge.In particular, tuyeres in the furnace became blocked with slag.... The tuyère was just a hollow tube made of clay, but I sent it to the British Museum and they analysed it and said it was part of a Bronze Age furnace, the mouth of the bellows. For making steel castings a modification known as a Tropenas converter is used, in which the air impinges on the surface of the metal from side tuyeres instead of from the bottom. Origin Late 18th century: French, from tuyau 'pipe'.
