Sulphur removal in ironmaking and oxygen steelmaking
process, typical sulphur levels in coke remain around 0.5%. Iron ore contains typically 0.01% sulphur and is only a minor source of sulphur in the steelmaking process [2,8]. In the BF-BOF process there are four process steps where sulphur can be removed:. BF;.

AOD stands for argon oxygen decarburisation, a refining process associated with the production of stainless steel. Most stainless steel is initially produced in an electric arc furnace before being transferred to a separate ladle furnace for refining to achieve the precise metallurgical content required – a process known as secondary metallurgy or secondary refining.

The whole process is controlled to ensure there is smooth flow of molten steel through tundish. Further, the impurities and slag are filtered in tundish before they move into the mold. The entrance of the mold is filled with inert gases to prevent reaction of molten steel with the gases in the environment like oxygen.
The 6 Steps in the Manufacturing Process of a Stainless …
Even though there are billions of users of stainless steel items around the world, there are very few people (relatively) who know what goes into making a stainless steel product from scratch. The manufacturing process of a stainless steel product is indeed fascinating and it gives you an insight into how far our ability to craft materials has evolved since the early days of the Industrial
Though the potential scope of multi‐objective genetic algorithm in the field of secondary steel making (SSM) is enormous, the useful utilization of such evolutionary techniques in secondary steel making process is yet to be done. In this work, data driven multi

Carbon Steel and Mild Steel | Metal Casting Resources
Once steel leaves the rolling mill, downstream companies use different secondary processing techniques to prevent corrosion and improve the properties of the metal. The predominant technique to do this is heat treatment. Heat treating The purpose of heat treating steel is to manipulate its mechanical properties by changing the distribution of carbon in the product and the internal microstructure.
