    Steel Making ProcessesHistory of Steel MakingModern Processes of Steel MakingAlthough men started producing steel since very earlier days, the commercialization was not started until it became 19th century. Before 19th, the crucible process was the only way of producing steel. After that the Bessemer process and Siemens-Martin process became popular in the 1850s and 1860s respectively. These methods become popular for steel making into a heavy industry.In the present day, we have two popular methods us在steelfeel上查看更多信息

    OverviewHistoryModern processesSee alsoExternal links

    Steelmaking is the process of producing steel from iron ore and/or scrap. In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel. Limiting dissolved gases such as nitrogen and oxygenand entrained impurities (termed "inclusions") in the steel is also important to ensure the quality of the produ

    Preparing Iron Ore For PelletizingThe Pelletizing ProcessThe Process Development Behind Iron Ore PelletizingConclusionIron ore must go through a lengthy pre-processing stage before it can be pelletized – a series of steps that work to beneficiate and concentrate low-grade ores. This process varies depending on the ore source, but typically involves various stages of crushing and grinding to reduce the size of the iron ore. Separation techniques such as magnetic separation or froth flotation are then used to separate the gangue (unwanted) materials 在feeco上查看更多信息
