New rail cars handle super hot iron at steel plants

Dec 29, 2023 · The cars — known as ladle cars — are designed to move hot iron via a railway-type track from the iron-smelting section of the plant to the steel-making section. Depending on the plant, that can be from 1 to 8 kilometers. Each car is equipped with driving controls and a power supply.

The Basic Oxygen Steelmaking (BOS) Process – Consortium Steel

The Basic Oxygen Steelmaking process differs from the EAF in that it is autogenous, or self-sufficient in energy. The primary raw materials for the BOP are 70-80% liquid hot metal from the blast furnace and the balance is steel scrap. These are charged into the Basic Oxygen Furnace (BOF) vessel. Oxygen (>99.5% pure) is “blown” into the BOF
