Jun 27, 2021· Quantity is for sure a problem: Since the 17th century, the first step in European steel production has been the smelting of iron ore into pig iron in a blast furnace. Originally employing charcoal, modern methods use coke, which has proven more economical. And then it comes also the related temperature problem

1) Steelmaking pig iron The silicon content of steel-making pig iron is not more than 1.7%, and the carbon exists in the form of Fe3C. Therefore, it is hard and brittle, and the fracture is white. It is mainly used as raw material for steelmaking and malleable cast iron. See the table below for steelmaking pig iron.

The temperature of the pig iron melt rises from 1250 °C to over 1600 °C. For this reason, approx. 20 % iron scrap is added for cooling in order to protect the converter lined with stones from excessive temperatures. Iron ore or sponge iron (from the direct reduced iron process) can also be used for cooling.

Since slag is just the impurities that are present in the bog iron ore prior to separation in the furnace, it can vary widely depending on the mineral makeup of the particular ore being refined. Much of these impurities are silicates, so the resulting ore looks like colored glass. Only from hot blast furnaces.
