Pig iron

Molten iron and slag start to drip through to the bottom of the furnace [the hearth]. Between the bosh and the hearth are the tuyeres [water cooled copper nozzles] through which the blast - combustion air, preheated to 900-1,300°C, often enriched with oxygen - is blown into the furnace. Immediately in front of the tuyeres is the combustion ...
