Blast furnaces have grown considerably in size during the twentieth century. In the early days of the twentieth century, blast furnaces had a hearth diameter of 4–5 m and were producing around 100,000 THM per year, mostly from lump ore and coke. At the end of the twentieth century the biggest blast furnaces had between 14 and 15 m in hearth diameter, and were producing 3–4 million tons of
