Between 5000 and 6000 years ago, metallurgy appeared in China. After entering the Iron Age in the 5th century BC, ironware became an important factor in promoting historical progress and once became a symbol of the level of productivity development.
Iron smelting is a combination of multiple technologies, and the blowing technology is an indispensable part of it. The blasting technology of metallurgical machinery in ancient my country has undergone the development from intermittent blasting to continuous blasting, and the blasting equipment has developed from piping to wooden fans and piston-type wooden bellows, during which horse and water platoons have also appeared. The development of blast equipment is not only an important part of the progress of iron smelting technology, but also as a kind of mechanical technology is affected by the overall level of mechanical technology. China's iron smelting machinery has shown a unique development context under the combined forces of various factors such as social politics, economy, and technological level.
