METHOD FOR OPERATING MOVING HEARTH REDUCING FURNACE |
摘要 |
A moving hearth reducing furnace is operated, while a gap is provided between a discharging apparatus (1) for discharging reduced iron agglomerates from the moving hearth reducing furnace and the surface of the moving hearth (2). The gap prevents squeezing metallic iron powder formed by reduction of powder included in iron oxide agglomerates into the surface of the moving hearth and the formation of an iron sheet. An iron oxide layer formed on the moving hearth (2) during the operation can be periodically scraped off without shutdown of the furnace.
