Former AHM blast furnace in Port of Sagunt, Valencia, Spain. A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being supplied above atmospheric pressure. [1]
Pelletizing. Pelletizing is the process of compressing or molding a material into the shape of a pellet. A wide range of different materials are pelletized including chemicals, iron ore, animal compound feed, plastics, waste materials, and more. The process is considered an excellent option for the storage and transport of said materials. [1]
Puddling (metallurgy) Schematic drawing of a puddling furnace. Puddling is the process of converting pig iron to bar (wrought) iron in a coal fired reverberatory furnace. It was developed in England during the 1780s. The molten pig iron was stirred in a reverberatory furnace, in an oxidizing [citation needed] environment to burn the carbon ...
The HIsarna ironmaking process is a direct reduced iron process for iron making in which iron ore is processed almost directly into liquid iron ().The process combines two process units, the Cyclone Converter Furnace (CCF) for ore melting and pre-reduction and a Smelting Reduction Vessel (SRV) where the final reduction stage to liquid iron takes place.
When construction on a house near the site began in the 1950s, “they found a lot of artifacts from the iron furnace,” Stout said, “including a cannon fragment. The fellow that lived in that ...
Rotary kiln (large rust-colored horizontal tube at center right) at a Wyoming cement plant. General layout of a direct fired countercurrent rotary kiln used in cement manufacture. Rotary kiln body, with drive gear and 2 tyres (riding rings) A rotary kiln is a pyroprocessing device used to raise materials to a high temperature ( calcination) in ...
In the iron and steel industry, direct reduction is a set of processes for obtaining iron from iron ore, by reducing iron oxides without melting the metal. The resulting product is pre-reduced iron ore. Historically, direct reduction was used to obtain a burr in a low furnace. At the beginning of the 20th century, this process was abandoned in ...
