建造高爐

高爐是一種用來煉鋼的高階裝置。將鐵礦石、木炭、和助焊劑在高熱環境中混合就能製造出一種比鍛鐵更強的金屬。

要搭建高爐，你必須先製作兩隻坩堝、一根鍛鐵鼓風口、和一個風箱。此外，你還會需要很多鍛鐵薄板和耐火磚塊。

製作高爐方塊本體就需要一隻坩堝，以及八張鍛鐵薄板。

You will then need to construct the blast furnace, along with its Chimney. The chimney must be composed out of Reinforced Fire Bricks, as they are strong enough to withstand the intense heat. These can be crafted from fire brick blocks, and either wrought iron or steel sheets.

最基礎的高爐結構。

The blast furnace's chimney can be up to five layers - each layer requiring eight Reinforced Fire Bricks to complete. Having more layers increases the total capacity of the blast furnace, allowing it to smelt more steel at once. Each chimney layer, up to a maximum of five, allows the blast furnace to hold four additional ore items.

必須從高爐的煙囪頂投入鍊鋼所需的素材。要鍊鋼，首先將等量的鐵礦石和助焊劑投入高爐。鐵礦石可以用任何能被熔化成鑄鐵的物品代替。另外，你還需要在高爐燃燒的過程中不斷加入木炭來維持燃燒。

與高爐方塊互動可以開啟高爐介面，如右圖所示。高爐介面會顯示爐中的金屬和燃料數量。螢幕右上角的空格必須放置一根鼓風口。有了鼓風口高爐才能達到可以鍊鋼的溫度。可以在砧上鍛造鼓風口。

要讓高爐達到鍊鋼的溫度，還需要在高爐方塊的任意鄰面放置一個風箱。

Finally, to get started, light the blast furnace with a Fire Starter, a Flint and Pyrite, or a Flint and Steel. It will begin to heat the ores inside. Make sure that the blast furnace continues to have fuel, and use the bellows to add air to the blast furnace after its internal temperature has reached the maximum for charcoal. After the ores inside heat up, they will melt and convert into Pig Iron.

熔融生鐵會從高爐中流入任何直接放置在其下方的容器（如坩堝）中。之後可從坩堝介面將熔融生鐵澆鑄至鑄錠模具中。你不能直接用生鐵製作工具或裝備，它還必須再經過一些其他工序處理之後才能使用。具體方法請參閱鍊鋼章節。
