WebBecause the process converted pig iron to steel, the vessel in which the operation was carried out came to be known as a converter. The principle of the bottom blown converter is shown schemati-cally in Fig. 1.1. At first, Bessemer produced satisfactory steel in a converter lined with siliceous (acid) refractories by refining pig iron that, Smelting is typically classified into two procedures: the wet process and the dry process. Electrolytic iron is considered the “wet process” since electrolysis requires electric charges to move through a liquid solution. This action causes a chemical reaction called electrolytic refining. The result of electrolytic refining is electrolytic iron. An anode (raw material) and a cathode (base plate) are immersed into an electrolyte including iron i… sydney watercraft ermington

During the refining process, sulfur dioxide is produced in massive quantities by oil refineries, which may be detrimental to the environment and to human health. Sulfur dioxide is taken out of the ... The product of the blast furnace is pig iron, which contains 4–5% carbon and usually some silicon. To produce a forgeable product a further process was needed, usually described as fining, rather than refining. From the 16th century, this was undertaken in a finery forge. At the end of the 18th century, this began to be replaced by puddling (in a puddling furnace), which was in turn gradually superseded by the production of mild steel by the Bessemer process.
