2019-7-26 · Arguably, the key development came in 1783-4, when Henry Cort introduced the puddling and rolling techniques. These were ways of getting all the impurities out of iron and allowing large-scale production, and a vast increase in it. The iron industry began to relocate to coal fields, which usually had iron ore

Process for the manufacture of steel

The invention describes a process for the manufacture of steel with a carbon content of <0.8 wt.-% by reducing iron ore and refining the hot metal. Iron ore and fuel are introduced into the reduction zone of a reactor that contains an iron melt in the reduction zone. This melt is covered by a liquid slag layer from which liquid slag is withdrawn.
