History of Hot Metal Production by Mini Blast Furnaces
摘要
The Chapter provides a brief description of the development of metallurgy from the bloomery the blast furnace, provides indicators of furnace productivity growth to the mid-twentieth century, and the main milestones in the development of pig iron production—coke as the main technological fuel and blast heating. It is shown that until the mid-twentieth century, the productivity of none of the “large” blast furnaces exceeded the production level of a modern compact or even mini-blast furnace.
