偶见你的问题，master heat、sub-heat的定义如下，希望对你有帮助。 master heat, n—a quantity of metal processed in a single furnace or refining vessel at one time in such a manner as to produce the desired composition and properties. Master heats may be used directly for producing castings or converted into ingot, bar, shot, or other suitable form, not including gates and risers from casting production, for later remelting as a sub-heat. sub-heat, n—a portion of a master heat remelted without additional processing for pouring into castings. Synonyms: melt, production heat. Sub-heats shall be produced from master heat metal in suitable batch sizes by electric induction furnace with or without atmosphere protection such as vacuum or inert gas. |
