To forge iron, a super-fuel:
冶炼铁需要一种超级燃料
Charcoal, wood burned in kilns,
就是窑炉烧出来的木炭
More carbon, more energy,
碳元素越多 能量越大
Burns hotter, longer.

They needed to smelt it,
为了熔炼出铁
to get that ore into a position
工人把铁矿石放在适当的地方
where it would interact with charcoal,
以便与木炭相互作用
and great groaning bellows would push air into this fire.
巨大的鼓风机往火炉里推送空气
The heat would infuse the iron,
高温熔化铁矿石
and it would coagulate into these chunks.
然后凝结成块状
