pig-iron(生铁、炼铁):指从高炉中冶炼出来、含碳量较高且含有一定杂质(如硅、硫、磷等)的粗铁,通常作为进一步炼钢或铸铁生产的原料。也常写作 pig iron。
/ˈpɪɡ ˌaɪərn/
Pig-iron is made in a blast furnace.
生铁是在高炉中冶炼出来的。
After the ore was smelted, the pig-iron was transported to the steel plant, where impurities were reduced and the metal was refined into steel.
矿石冶炼成生铁后被运到钢厂,在那里降低杂质含量并进一步精炼成钢。
pig-iron 这一名称来自早期铸造工艺:把铁水浇入一条主沟(像“母猪”),再分流到多条侧沟形成一排排锭块(像“小猪”吸奶),这些锭块就被称为 pigs,由此得名 pig iron(生铁锭、生铁)。
