Steel is a metal key. And use than other metals. Global steel production estimated percentage. 96 average in all of metal each year. The steel industry is. Century Buddhism began around 9, but also obstacles in the production of steel and can not be very time-generation steel (Iron Age) has started seriously in the 20th century, Buddhism is squandering steel from iron ore. The squandering a blast furnace (blast furnace) in the first fuel is wood charcoal. To use coal (coal) currently used Teanocgk (coke) instead of coal, steel production during the 20 century, Buddhism is not good quality steel. Most iron in the form of squandering (pig iron), even a poor quality steel. But the popularity has led to benefits. It features better than other metals. In Buddhist century Sir Henry 23 Best Access Merrill (Sir Henry Bessemer, harbor in 1813 -1893, the British engineers) find a way to squander your steel - better known properties of steel (steel) that. plate hardness can be increased. And other features. Great discoveries of Sir Henry Best Access Merrill makes steel quickly. Time and very low. Considered that the revolutionary steel industry.
There are several types of iron ore. Each has different components. Iron ore is scattered almost throughout the world. But good quality iron ore. Total concentration is high. And a sufficient amount of minerals to produce steel are not many of the players. The following types of iron ore is.
1. Hematite is a mineral right to squander the steel. Of iron ore is in the form of oxides. With chemical formula Fe2O3 that is a red iron ore. Steel has about 70 per cent found in USA - America, Australia, the Soviet Union.
2. Magnetite ore that is suitable to use as squandering iron ore a chemical formula Fe3O4 that is black and steel percentage approximately 72 to 73 found in the United States, Sweden and China.
3. Siderite ore is brown with a low number concentration. And iron in the form of a carbonate chemical formula that is iron FeCO3 approximately 47-49 per cent preferred not to squander it with a minimum amount of iron minerals found in the United States, UK and Germany.
4. Limonite minerals are brown and the iron ore in the form of oxide compounds in a chemical formula that Fe2O3 X (H2O) with iron about 60-65 per cent found in France, the United States.
5. Pyrite in iron ore in the form of supporting a recipe that is light Grand FeS2 is a brown steel approximately 60 percent due to iron in the form of supporting a Grand light. Is not popular to be squandering. Because the sulfur in the ore to make steel, sulfur has been squandering doctor become brittle steel.
In Thailand as the survey. Iron minerals found in many areas, such as iron ore they lean buffalo. Lopburi. Echiyongcan Province, Muang District, all provinces all his nondescript Kanchanaburi him - Steel Nakhon Si Thammarat. Mineral found mostly Hematite minerals and mineral supply some Magnetite enough to unlock the steel industry or squander steel industry has. But the lack of investment. Because the steel industry is squandering the money fund industry.
In the steel industry. Steel production was divided into 2 major methods together is.
1. Squandering iron directly from iron ore. Squandering divided into 2 sub-method approach is squandering squandering steel. The squandering a blast furnace. Steel and squandering squandering way reduce oxygen directly (direct reduction) production by this method after suitable sources of natural gas a lot.
2. The steel used to melt scrap steel in the new electric stove. Steel production by this method does not require iron ore.
