It is relatively abundant and can easily be extracted and modified due to its useful material properties, all of which results in low prices. After the industrial revolution (18-19th century), iron became a core material of industrial markets, its importance reflected in the phrase “iron is nation”; its production was directly regarded as an indication of national power. Especially after World War II, governments vigorously supported the growth of an iron industrial market, which significantly contributed to the development of a global economy. Iron is extracted from its ore and smelted in a metallurgical furnace called a "Blast Furnace". The blast furnace method is expected to survive into the 22nd century because of its efficient rate of iron production at competitive costs compared with other iron making methods. Blast furnaces keep on improving with adaptations arising from new technologies driven by rising global demand, yet the main chemical process remains same. But process improvement cannot solve many of the problems associated with blast furnaces. The rate of iron production is highly influenced by fluctuations in the world economy, and improving the operational efficiency of the process is of major concern. However, the biggest drawback of blast furnace operation is the inevitable carbon dioxide production from iron reduction processes, which is considered one of the major contributors in global warming. Accordingly, the Pulverized Coal Injection (PCI) method is becoming an internationally popular method for improving blast furnace operation. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pulverized coal injection method」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
