Whereas only a handful of decades ago, typical blast furnace working volumes were below 1000 m3, such furnaces are currently designated compact or even mini blast furnaces. For certain business cases, however, small furnace sizes remain an attractive option.
The Mini Blast Furnace (MBF) is the most proven technology, as revealed by one recent global iron production data. While gas-based as well as coal-based DRI production routes produced 2.7% of total iron production in 1990 - 1991, the corresponding share held by MBF, operating mainly in Brazil, China and India, was 3.4%.
the modern Paul Wurth blast furnace combines proven solutions with new and latest developments to provide the best gain from the project – capital cost, project implementation, operation ramp-up, availability, safety, environmental compliance, long campaign life, total cost of ownership, etc.
The mini blast furnace process is an efficient route to produce pig iron based on the burden with granulated charcoal. New, improved technologies have recently been introduced in the mini blast furnace process, such as pulverized charcoal and gas injections, new burden materials, and peripheral devices that improve the overall process efficiency.
