The oldest extant blast furnaces were built during the Han Dynasty of China in the 1st century BC, that's pretty interesting if you ask me.
And of course the fact you get a 'SLAG' at the end.
Blast furnaces can be categorized into several types based on their design and operational characteristics. The most common types include the traditional vertical blast furnace, which is used primarily for iron production, and the cupola furnace, often utilized for melting cast iron. Additionally, there are modern variants like the top-blown oxygen converter and the shaft furnace, which employ different technologies to enhance efficiency and reduce emissions. Each type is tailored to specific metallurgical processes and production needs.
The problems that iron impurities can cause in a blast furnace can include the iron not melting down correctly, obnoxious fumes being created, and the impurities could ruin an entire batch of melted iron.
Blast furnaces are efficient for producing iron and steel, allowing for high-volume production and the use of various raw materials. They can also be integrated with other processes, enhancing overall productivity. However, they are energy-intensive and contribute significantly to carbon emissions, raising environmental concerns. Additionally, the initial capital investment and maintenance costs can be substantial.
Provided you are nowhere near the focal point of the furnace then they are perfectly safe.
The man ran into the hot furnace to save the boy that was stuck in there.

A blast furnace is used to extract iron from its ore.

A blast furnace.
iron is collected from blast furnace by drilling the taphole.Taphole is a hole drill and plug after cycle of time located in blast furnace bottom.
Useful Volume of Blast Furnace is the volume of the furnace from the throat level to the level where the taphole is placed. This is known the way basically because that is the region where the useful products from Blast furnace are present.
A blast furnace runs continuously, and input materials are continually dumped in at the top to make their way down through the furnace. Shutting down a blast furnace for relining or other work is a major event in its life.
