Hurstwic: Iron Production in the Viking Age

The iron ore shown to the right was excavated from Skógar, a Viking-age iron-making site in Iceland. The larger piece is about 2cm (less than 1in) in the long dimension. Sometime about 1000 years ago, someone gathered this iron ore, processed it, transported it to the iron smelting site, but for unknown reasons, never used it in a smelt.

Direct reduced iron - Wikipedia

Process. Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to drive off the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).

How is Iron Refined from Ore? (with pictures)

Feb 10, 2021· Although iron does not occur in its pure form in nature, some kinds of ore contain up to 70% iron atoms. Iron ore consists of oxygen and iron atoms bonded together into molecules. To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process.

Iron Making | Boundless World History

Rolling replaced hammering for consolidating wrought iron and expelling some of the dross. Rolling was 15 times faster than hammering with a trip hammer. Hot blast, patented by James Beaumont Neilson in 1828, was the most important development of the 19th century for saving energy in making pig iron.

SLAG IN THE PRODUCTION OF WROUGHT IRON

Direct reduction processes of production of wrought iron from iron ore have take place at about 1200°C. At those temperatures slag has to be liquid. The objective of our re-search was to describe mechanisms of wrought iron production. METHODOLOGY Two slag, primary and final, are formed during the reduction process in making pig iron.
