skos:scopeNote
Aleación de hierro que incluye característicamente carbón y silicio, con gran resistencia a la compresión, pero baja resistencia a la tensión. Una amplia gama de construcciones y elementos decorativos son fabricados con hierro fundido, al vaciar el metal fundido en moldes de arena y después mecanizarlos. An iron alloy containing about 2 to 4% carbon and 1 to 3% silicon, having a high compressive strength but low tensile strength. Cast iron is manufactured by melting scrap iron or pig iron in a cupola that is in contact with the coal fuel, then casting the molten iron into a mold. A large range of building and decorative items are made of cast iron by pouring the molten metal into sand molds and then machining. It is inexpensive and easy to make. It was made in China by at least the 3rd century BCE; the technique for its production did not reach Europe until medieval times. Een ijzerlegering die koolstof en silicium bevat, met een hoge compressiesterkte maar een lage treksterkte. Er worden zeer veel verschillende objecten van gietijzer gemaakt door het gesmolten metaal in zandvormen te gieten en vervolgens machinaal verder te verwerken. De objecten worden gebruikt in de bouw en als decoratieve en gebruiksvoorwerpen. 一種鐵合金,含有2%到4%的碳及1%到3%的二氧化矽,抗壓強度高,不過拉伸強度卻很低。接觸煤燃料之熔鐵爐熔化廢鐵或生鐵,之後將熔融鐵注入鑄模而製成鑄鐵。大規模建築物與裝飾物品都以鑄鐵製成,製成方式將熔融金屬注入沙模後再以機器加工,製造過程便宜且容易。最晚西元前三世紀中國就可製造這種鐵製品,不過該技術一直到中世紀才傳至歐洲。
