Historic Blast Furnace Diagram: Iron Production Process Explained #30901 (License: Personal Use)

This intricate line engraving depicts a cutaway view of a traditional blast furnace in operation, with raw materials (ore, coke, limestone) loaded at the top, descending through the stack where they react under intense heat from forced air blast. Molten iron collects at the hearth and is tapped via a taphole, while slag floats above and is removed separately; workers and rail carts on the upper platform indicate manual handling typical of the era. The illustration includes labeled components (e.g., D for tuyères, G for taphole) and shows structural details like refractory lining and gas outlets.
