Abstract
This blast furnace facility is provided with: a blast furnace main body (110); starting material charging means (111,113) that charge a starting material (1) containing iron ore and coke into the interior of the blast furnace main body (110) from the apex thereof; hot airflow blow in means (114, 115) that blows in a hot airflow (101) from a tuyere to the interior of the blast furnace main body (110); and blast furnace blow in charcoal supply means (120, 129) that blow in blast furnace blow in charcoal (11) from the tuyere to the interior of the blast furnace main body (110). The blast furnace blow in charcoal supply means (120, 129) blow in a blast furnace blow in charcoal (11) having an oxygen atom content (on a dry basis) of 10 20 wt% and an average pore size of 10 50 nm.
