This is a plug and plugs have at least two prongs these days. Unless they are plugging there appliances into a lighting circuit of a building with knob and tube then this might be the equation to use. This more than likely is a/c current and not a power supply. …
The second category of furnace is the forced-air, atmospheric burner style with a cast-iron or sectional steel heat exchanger. Through the 1950s and 1960s, this style of furnace was used to replace the big, natural draft systems, and was sometimes installed on the existing gravity duct work.
The extraction order is Zn > Mn > Co > Ni and extraction percentage of metal ions was increased with increase of the concentration of extractant, initial pH of aqueous phase and ratio of O/A. The separation of cobalt, zinc and manganese from nickel was effectively accomplished at the condition of extraction stage = 1, O/A = 1 and initial pH 5.0 ...

reduce their power suppliers’ unit costs. At present, hydroelectric sources produce the power for about two-thirds of world aluminum production, although placing a smelter next to a nuclear power plant can also be economically attractive, as at Dunkerque in France. Fig. 2.3 shows an aluminum smelter with its long potrooms and tall alumina silos.

A cupola or cupola furnace is a melting device used in foundries that can be used to melt cast iron, Ni-resist iron and some bronzes. The cupola can be made almost any practical size. The size of a cupola is expressed in diameters and can range from 1.5 to 13 feet (0.5 to 4.0 m).
Extraction of Iron. ... HUGE amounts of energy and this is normally the reason why aluminium smelters are normally located near hydroelectric power plants – providers of cheap electricity. Alloys. The majority of the metallic substances that we use today are alloys. Alloys are mixtures of two or more metals as well as other elements.

The crown plate is the platform the fuseable plug is screwed into on a boiler. It protects the boiler from exploding when the water level drops to an unsafe level.
One major example of a shale field is in North Texas (Dallas and Fort Worth) where the Barnett Shale stretches over 8,000 square miles and holds 86 trillion cubic feet of natural gas, enough to power all of homes in the US for almost 20 years.

Iron: Pure iron does not have a variety of uses. But alloys of iron such as steel are highly useful. Alloys are nothing but a mixture of different types of metals. Alloys of Irons are used to make cars, nails, bridges etc. We are going to discuss in details about the different types of iron in the extraction of the iron part.
Ferrous metallurgy is the metallurgy of iron and its alloys.It began far back in prehistory.The earliest surviving iron artifacts, from the 4th millennium BC in Egypt, were made from meteoritic iron-nickel. It is not known when or where the smelting of iron from ores began, but by the end of the 2nd millennium BC iron was being produced from iron ores from Sub-Saharan Africa to China.

Properties of iron. Like all metals, iron is a very good conductor of both heat and electricity. It is also strong, ductile and malleable. A common problem with iron is that in moist air it rusts.
Secondary steelmaking uses scrap steel as the primary raw material. Gases created during the production of steel can be used as a power source. Primary Steelmaking. Basic oxygen steelmaking is a method of primary steelmaking in which carbon-rich molten pig iron (the iron created in the blast furnace) is made into steel.
Galvanised iron is the name given to iron that has been dipped into molten zinc (at about 450°C) to form a thin covering of zinc oxide. One level of rust prevention occurs through a purely mechanical method since it is more difficult for water and oxygen to reach the iron.
Today, it is estimated that the global steel industry used about 2 billion tonnes of iron ore, 1 billion tonnes of metallurgical coal and 575 million tonnes of recycled steel to produce about 1.7 billion tonnes of crude steel. Recycled steel (sometimes called scrap steel) is one of the industry’s most important raw materials.
Iron Oxide is a black crystal or a reddish-brown powder. It is used in polishing compounds, pigments, and metallurgy. Iron Oxide fume is produced when materials containing Iron are heated, as in arc welding. DOT number UN 1376 refers to Ferrous Oxide (FeO), Iron Oxide (Spent) or Iron Sponge. Ferrous Oxide (FeO) may be formed in Oxygen-limited

In the study, metal extraction processes are requiring energy and are uneconomical as iron (hematite) in the red mud has first to be converted into magnetite using reductants at a relatively high temperature of 400–800 °C before magnetic separation. The recovery of iron metal from the magnetic fraction needs a still higher temperature.
Electricity is everywhere, and could theoretically power electric cars anywhere we wish to go. But recharging an electric car requires a charging station, and the vast majority of places lack charging stations. Using extension cords, power adapters, and a portable charging station can help you charge through a regular power outlet.
The effectiveness of the Chinese blast furnace was enhanced during this period by the engineer Du Shi (c. AD 31), who applied the power of waterwheels to piston-bellows in forging cast iron. Donald Wagner suggests that early blast furnace and cast iron production evolved from furnaces used to melt bronze.
