    Sometime after 2025, an automaker will have the bragging rights to the first car to feature steel components made via a fossil-free production process. Specifically, instead of CO2 emissions, only H2O (water vapor) will be released during the conversion of iron ore to iron; then that iron will be made into steel. Imagine how that automaker’s environmental leadership, and marketing status

    Jul 01, 2021 1. Introduction. Annually, 2.6 billion tons of iron ore (mostly hematite) are converted into steel by the integrated blast furnace (BF) and basic oxygen furnace (BOF) route , accounting for approximately 70% of the global steel production.The remaining 30% is realized by melting steel scraps and directly reduced iron (the latter is also referred to as sponge iron) in electric arc furnaces (EAF)

    Mill scale is one of waste materials which is produced as a result of hot rolling of steel in all steel companies. On the other hand, mill scale is considered a rich iron source with minimum impurities. This work aims at conversion of mill scale by adjusting smelting processes to produce different valuable products. The smelting processes were carried out using carbothermic reduction in a

    Steel-making: the basic oxygen process. Impurities in the iron from the Blast Furnace include carbon, sulphur, phosphorus and silicon. These have to be removed. Removal of sulphur. Sulphur has to be removed first in a separate process. Magnesium powder is blown through the molten iron and the sulphur reacts with it to form magnesium sulphide. This forms a slag on top of the iron and can be removed

    The blast furnace is the first step in producing steel from iron oxides. The first blast furnaces appeared in the 14th century and produced one ton per day. Even though equipment is improved and higher production rates can be achieved, the processes inside the blast furnace remain the same. The blast furnace uses coke, iron ore and limestone to produce pig iron. Coal is a key part of the coke-making process
