Blast furnace - Wikipedia

Blast furnace. In contrast, air furnaces (such as reverberatory furnaces) are naturally aspirated, usually by the convection of hot gases in a chimney flue. According to this broad definition, bloomeries for iron, blowing houses for tin, and smelt mills for lead would be classified as blast furnaces.

Wrought iron - Wikipedia

PropertiesEdit. Although it appears that wrought iron and plain carbon steel have similar stone compositions, that is deceiving. Most of the manganese, sulfur, phosphorus, and silicon are incorporated into the slag fibers present in the wrought iron, so, really, wrought iron is purer than plain carbon steel.

Iron processing |

Creating Iron | HowStuffWorks

­The more advanced way to smelt iron is in a blast furnace. A blast furnace is charged with iron ore, charcoal or coke (coke is charcoal made from coal) and limestone (CaCO 3 ­). Huge quantities of air blast in at the bottom of the furnace, and the calcium in the limestone combines with the silicates to form slag.

Slag - Wikipedia

Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron loss and so mainly contains oxides of calcium, silicon, magnesium, and aluminium. Any sandy component or quartz component of the original ore automatically carries through the smelting process as silicon dioxide.
