Bessemer Process - an overview | ScienceDirect Topics
The bessemer process reduces molten pig iron in so-called bessemer converters—egg-shaped, silica, clay, or dolomite-lined containers with capacities of 5 to 30 tons of molten iron. An opening at the narrow upper portion of the bessemer converter allows iron to be introduced and the finished product to be poured out.
Open Hearth Process - an overview | ScienceDirect Topics
Jan 7, 2011 · Steels may be broadly considered as alloys of iron and carbon, the carbon percentage varying from about 0.1% in mild steels to about 1.8% in some hardened steels. These may be produced by one of four different processes, the open hearth process, the Bessemer converter process, the electric furnace process, or an oxygen process. Processes may be ...
Converter Steelmaking - ScienceDirect
Jan 1, 2014 · The original Bessemer converter had acid silica lining that made it impossible to refine high-phosphorus hot metal, which was a common product from some British blast furnaces at that time. The problem was solved when S.G. Thomas and P.C. Gilchrist succeeded to develop basic doloma lining and to apply it industrially in 1879 [2].
Converter Steelmaking - ScienceDirect
Jan 1, 2024 · The basic idea of converter processes is to convert carbon-rich liquid, blast furnace hot metal to low-carbon steel. The converter processes emerged in the mid-19th century with the invention of the Bessemer processbased on bottom-blowing of air to decarburize hot metal. Oxygen refining was developed about one century later, first by oxygen ...
Note on the modifications of the bessemer steel process
In the regular Bessemer process, the shape of the converter, it will be remembered, is simply that of a bulging vase, with the tuyères or blast holes in the bottom. The vessel is generally movable ábout a horizontal axis through 18ol, but occasionally it is fixed.
Converter Process - an overview | ScienceDirect Topics
In practice, they mean the same subject but limit the field to modern converter processes using basic furnace lining and slag (opposite to acid practice), and oxygen for carbon oxidation thus differing from older processes using air. The origins of the current converter processes are in the second half of the 1800s in Bessemer and Thomas processes.
Review of copper pyrometallurgical practice: today and tomorrow
Oct 1, 2003 · Although the production of the “red metal” copper has been conducted for many centuries, technical development has achieved significant advances during the past 120 years. Notable developments such as the Bessemer converter and copper electrolysis have contributed to the production of high purity copper.
What the steel industry owes to bronze powders - ScienceDirect
Nov 1, 2013 · It is probably not widely known that Henry Bessemer (1813-1898), an English inventor of the 19 th century, famous for his Bessemer converter steel-making process, actually built his initial fortune from the manufacture of bronze powder. The prolific inventor, born 200 years ago, began his career in his father's type foundry in Hertfordshire ...

Recent progress in open hearth steel practice - ScienceDirect
Abstract. The basic open hearth furnace, the world's greatest steel producer at present, suffers under the disadvantage of greater cost of operation than the Bessemer converter, due chiefly to costs for fuel, labor and repairs. Constant experiments are being made at steel works to reduce these expenses, and the important modifications in design ...
