4 Code – The Code of Standard Practice for Steel Buildings and Bridges as published by the American Institute of Steel Construction. Column – a structural element that usually carries its primary loads in compression or tension parallel its axis. Column Base – usually a thick plate at the bottom of a column through which
3.3.3.1 Direct Reduced Iron. DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron

1/12/2018 · In this paper, we propose and assess a potential design for a fossil-free steelmaking process based on direct reduction of iron ore with hydrogen. We show that hydrogen direct reduction steelmaking needs 3.48 MWh of electricity per tonne of liquid steel, mainly for the electrolyser hydrogen production.
