Method for forming a moving hearth in a furnace for producing reduced iron agglomerates

摘要

A moving hearth is formed by providing a layer of hearth material 4 primarily composed of iron oxide on a base refractory 3 in a reducing furnace and then sintering the hearth material so that the sintered moving hearth is not melted at an operational temperature in a reducing step. The moving hearth has high durability, and can maintain surface flatness during operation.
