The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace. The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron.
Göran Fredrik Göransson (20 January 1819 – 12 May 1900) was a Swedish merchant, ironmaster and industrialist.He was the founder of the company Sandvikens Jernverks AB (now called Sandvik AB) and was the first person to implement the Bessemer process successfully on an industrial scale and pioneered ingot steel in the Swedish iron and steel industry.
Integrated steel mill in the Netherlands.The two large towers are blast furnaces.. A steel mill or steelworks is an industrial plant for the manufacture of steel.It may be an integrated steel works carrying out all steps of steelmaking from smelting iron ore to rolled product, but may also be a plant where steel semi-finished casting products are made from molten pig iron or from scrap.
A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.
Bessemer licensed the patent for his process to five ironmasters, but from the outset, the companies had great difficulty producing good-quality steel. [19] Mr Göran Fredrik Göransson , a Swedish ironmaster, using the purer charcoal pig iron of that country, was the first to make good steel by the process, but only after many attempts.

The Edgar Thomson Steel Works was designed and built because of the Bessemer process, the first inexpensive industrial process for the mass production of steel. In the process, air blowing through the molten iron removed impurities via oxidation. This took place in the Bessemer converter, a large ovoid steel container lined with clay or dolomite.
