Making steel from iron. More pig iron is added, the unwanted carbon combines with oxygen, the impurities are removed as slag and the iron turns to molten steel. Skilled workers sample the steel and continue the process until the iron has exactly the right carbon content to make a particular type of steel.
DRI production Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal.
Some of the major casting techniques involved in the commercial foundry are Sand casting, Shell casting, Die casting, Investment casting and lost casting. Die Casting : Die casting is a versatile process enabling the highspeed production of complex and intricate appliances on a mass scale.
This book will help industrial process innovators in research, development and commercial startup to assess the risks of commercialscale implementation and provide them with practical guidelines and methods to reduce the risks to acceptable levels.
Direct Reduced Iron (DRI), also known as Sponge Iron, offers an alternative steel production route to BFBOF and ScrapEAF routes. In DRI, iron ore is reduced in its solid state – unlike BF process where a liquid metal is formed during reduction.

This statistic shows the worldwide iron ore production, by country. The mine production of iron ore in the United States reached approximately 55 million metric tons in 2011.
The starting point in the commercial production of iron and steel is the smelting of iron ore to produce pig iron. The principal iron ores are given in the table. ... Production of Pig Iron ... WATCH PIG IRON PRODUCTION PROCESS VIDEO HERE. October 2, ...
Transportation distances of resources and of hydrogen itself have to be minimized and the production has to be realized in decentralized small scale production facilities. At Graz University of Technology the reformer steam iron process is developed as a scalable, onsite process, to emphasize on the requirements of natural resources.
Modern Taconite Production. Iron ore is both mined and upgraded on Minnesota's Mesabi Iron Range. After being extracted from the ground, low grade iron ore is hauled from openpit mines to nearby taconite processing facilities, where it is crushed into a fine powder.
The iron and steel production source category consists of facilities with any of the following processes: Taconite iron ore processing. Integrated iron and steel manufacturing (production of steel from iron or e or iron ore pellets). Coke making not colocated with an integrated iron and steel manufacturing process.
