A foundry is a factory that produces metal castings. Metals are cast into shapes by melting them into a liquid, pouring the metal in a mold, and removing the mold material or casting after the metal has solidified as it cools. The most common metals processed are aluminium and cast iron. However, other metals, such as bronze, steel, magnesium, copper, tin, and zinc, are also used to produce castings in foundries.
In metalworking, casting involves pouring liquid metal into a mold, which contains a hollow cavity of the desired shape, and then allowing it to cool and solidify. The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process. Casting is most often used for making complex shapes that would be difficult or uneconomical to make by other methods.
Melting is performed in a furnace. Virgin material, external scrap, internal scrap, and alloying elements are used to charge the furnace. Virgin material refers to commercially pure forms of the primary metal used to form a particular alloy. Alloying elements are either pure forms of an alloying element, like electrolytic nickel, or alloys of limited composition, such as ferroalloys or master alloys. External scrap is material from other forming processes such as punching, forging, or machining. Internal scrap consists of gates, risers, defective castings, and other extraneous metal oddments produced within the facility.
Føste gaongen di kom va ra med kvite krist å kråss,
maonge ao åss nekta å ta imot dinna bysle krist,
men nåken ao åss svikta. Jor å stidling i stan før haidn skjikk.
No mao mi ao å lima, ain kamp mot kristne fanta.
Torshammaren vart knuste, irstatta me ain kråss.
Sjonging ao tona, irstatta me bysle or.
Bloting føbåe, irstatta me gustineste.
Håvi vart brende, irstatta me kjørkje.
No mao mi ao å lima, ain kamp mot kristne fanta.
Dan andre gaongen di kom va ra so bedrevitara me sokadla konnskap.
Maonge ao åss nekta å verta so byfanta, nåken ao åss svikta.
Status å innpass i stan før sont bondevit.
No mao mi ao å lima, ain kamp mot byfanta.
Hauga å vådla føsvinde, store bygj å bue.
Spraoke vaort vert utvatna, ao ti å, i ti e.
Bjor å laug, ti søte vin å rapavatn.
Fjøsbrok å trisko, ti vie brøke å tåskne sko.
