The process begins by preparing the puddling furnace. This involves bringing the furnace to a low temperature and then fettling it. Fettling is the process of painting the grate and walls around it with iron oxides, typically hematite; this acts as a protective coating keeping the melted metal from burning through the furnace. Sometimes finely pounded cinder was used instead of hematite.

Quick cooling produces fine grain construction and slow cooling produces coarse grain construction. Cast iron that has not cooled evenly produces a low-quality cast. Other problems faced during the cast iron process include contamination of the iron, gas porosity (the forming of bubbles in the iron), and problems with the fluidity of the metal.
The smelting and refining process for iron and steel in the BF-BOF process involves the carbon reduction of iron ore (Fe 2 O 3) in the BF to make molten iron, and decarburization of molten iron in the BOF to make molten steel. Major reducing agent in the BF is the carbon monoxide gas(CO) generated by the oxidation of the carbon(C) in coke. ...

Cast-iron architecture is the use of cast iron in structures for human activities, from bridges and covered markets, to warehouses and churches. First developed during the Industrial Revolution, cast iron became relatively cheap, and was common as a structural material and for decorative uses in the second half of the 19th century, until it fell out of fashion as a decorative material, and was ...
Cast-iron architecture was a popular type of building design used throughout the world in the mid-1800s. Its popularity was due, in part, to its efficiency and cost-effectiveness — a regal exterior facade could be mass-produced inexpensively with cast iron.
The basic raw material for steel manufacture is either the hot metal from the blast furnace, steel scrap or a mixture of both. The proportions of material used vary according to the process and the type of steel required. Steel can be described in general terms as iron with most of the carbon removed, to make it tougher and more ductile. There ...
Cast iron was used extensively in the U.S. Capitol's mid-19th century House and Senate extensions and new dome. A popular construction material at the time, it was used for bridges, pipes, machinery and many other objects until it was widely supplanted by steel.
Transformer Construction of the Core. Generally, the name associated with the construction of a transformer is dependant upon how the primary and secondary windings are wound around the central laminated steel core. The two most common and basic designs of transformer construction are the Closed-core Transformer and the Shell-core Transformer.
