Summary
[edit]
| Description |
Français : Procédé de réduction directe inventé par Husgafvel (vers 1886). Il s'agit d'un bas fourneau continu (ou plutôt séquentiel) au charbon de bois. C'est en réalité un stückofen modernisé construit comme un grand four à cuve (environ 26 pieds de haut), avec un refroidissement des parois à l'air, qui sert à pré-chauffer le vent. Il a un "creuset" amovible avec 4 trous de tuyères refroidis à l'eau, en vis-à-vis et sur deux niveaux. Le vent est soufflé dans les trous inférieurs et, quand le creuset se rempli, ceux-ci sont bouchés et l'opération continue sur les trous supérieurs. Quand le creuset est rempli jusqu'au trous supérieurs, the vent est arrêté et le creuset retiré. Un nouveau creuset vide est mis en place et le process est recommencé.
English: Direct reduction process invented by Husgafvel (circa 1886). It consists in a continuous bloomery, working with charcoal. It is, in fact, a modern stückofen built as a tall shaft furnace (about 26 feet high), with double air-cooled walls between which the blast was preheated. It had a movable hearth with four water-cooled tuyere holes on each of the two opposite sides on two levels. The blast was introduced in the lower holes first and, as the hearth filled up, these were plugged up and the upper ones used. When the hearth was filled up to these, the blast was stopped and the hearth removed. A fresh hearth was put in place and the process continued. |
