MINI MILLS World electric steelmaking has increased from 595Mt in 1960 to 1,606Mt in 2013, an increase of 170%. Since their early beginnings in the 1970s, mini mills have gradually grown in size to capture the economies of scale and have now reached capacities exceeding 1Mt/yr and a typical mini mill has increased its output from 0.50 to 3.0Mt/yr.
Mini Mills - Steel Warehouse
Mini mills, the result of innovative technology and market competition, are smaller, cheaper, and more flexible than traditional integrated mills. Instead of creating steel from iron ore and coke, as integrated mills do, mini mills melt steel scrap. They are less dependent on natural resources and require less space, so there is more freedom to ...
Minimills produce a variety of steel products that vary in their carbon content and in the amount and composition of alloying elements. Most of the steel produced in minimills is carbon steel used in the manufacture of construction materials, automobiles, appliances, and other applications.
