Sponge Iron Production Corex Process In Venezuela

1 BACKGROUND

method for production of hot metal. In 1970s, however, a process for the production of liquid iron without using coke – or using lowgrade coke and coal – was patented. The possibility that a smeltingreduction process could be based on the use of coal alone was first investigated by Korf Stahl in This was the origin of the Corex ...

Nonblast Furnace Iron Making Technology

However, the sharp drop in gas prices due to the Marcellus shale development has led to resurgence in interest in gas based DRI production. COREX is the first commercially operating alternative to the blast furnace for hot metal production, and HIsmelt is the world's first commercial smelting process for making iron straight from the ore.
