2023.10.6 Blast furnace ironmaking is a continuous metallurgical process in which iron ore is reduced to liquid pig iron in a blast furnace. It is developed and improved from the ancient shaft furnace ironmaking. In China, the blast furnace is named for its vertical tubular shape and slender furnace body.

The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way.
