I remember reading many years ago (60s?), that Chinese rural regions were being encouraged to produce their own iron from locally available materials. This was because iron ore, limestone and charcoal/coal were often locally available and the cast iron produced was sufficient for many purposes without further refinement.
IIRC the furnace was simple and based on 40 gallon drum(s). I don't remember how it was blown.
Does anyone know the details of the Chinese furnace?
