Summary edit
| Description |
Français : Procédé de réduction directe appelé bas fourneau américain. Le minerai en poudre, mélangé avec du charbon de bois, est chargé à intervalles réguliers. Une loupe est produite toutes les 3 heures, le laitier est coulé hors du four. Gourmand en énergie, ce procédé a disparu peu après 1890. English: Direct reduction process named American bloomery. The iron ore powder, mixed with charcoal, is regularly charged. A pasty bloom is produced every 3 hours, and slag is taped out of the furnace. Needing much fuel, this process disapeared shortly after 1890. |
