The bloomery was the earliest form of smelter capable of smelting iron. Bloomeries produce a porous mass of iron and slag called a bloom. The mix of slag and iron in the bloom, termed sponge iron, is usually consolidated and further forged into wrought iron. Blast furnaces, which produce pig iron, have largely superseded bloomeries.
The Manufacture of Iron -- Filling the Furnace, an 1873 wood engraving. Many furnace designs for smelting combine ore, fuel, and other reagents like flux in a single chamber. Mechanisms, such as bellows or motorized fans, then drive pressurized blasts of air into the chamber. These blasts make the fuel burn hotter and drive chemical reactions.
Blast furnaces are currently rarely used in copper smelting, but modern lead smelting blast furnaces are much shorter than iron blast furnaces and are rectangular in shape. [76] Modern lead blast furnaces are constructed using water-cooled steel or copper jackets for the walls, and have no refractory linings in the side walls. [77]
The design of water jacket furnaces differ from the conventional blast furnaces used for smelting iron ore, which use a hot blast. Water jacket furnaces typically used a cold air blast, typically provided by a positive-displacement blower, such as a Roots blower. Preheating of the air blast was used on some water jacket furnaces. [15]
The tatara (鑪) is a traditional Japanese furnace used for smelting iron and steel. The word later also came to mean the entire building housing the furnace. The traditional steel in Japan comes from ironsand processed in a special way, called the tatara system. [1] Iron ore was used in the first steel manufacturing in Japan.
Electric phosphate smelting furnace in a TVA chemical plant (1942) Smelting is a process of applying heat and a chemical reducing agent to an ore to extract a desired base metal product. [1] It is a form of extractive metallurgy that is used to obtain many metals such as iron, copper, silver, tin, lead and zinc.
Wundowie charcoal iron blast furnace in 1952. The Wundowie charcoal iron and wood distillation plant manufactured pig iron between 1948 and 1981 and wood distillation products between 1950 and 1977, at Wundowie, Western Australia. Originally a state-owned enterprise, it seems not to have been incorporated as a company, during the time it was ...
They smelted the iron ore in a small blast furnace—capable of smelting 5 cwt of iron, and which they had made themselves with Rowley's assistance—tapped the molten iron into a ladle and then poured it into a pipe mould. [174] They had produced pig-iron and successfully cast it to make a sample pipe—nine feet long and four inches in ...
