Document Type and Number:

Japanese Patent JP2997459

Kind Code:

B1

Abstract:

A moving hearth is formed by providing a layer of hearth material primarily composed of iron oxide on a base refractory 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 is more easily constructed compared to providing a shaped or amorphous refractory on the base refractory, has high durability, and can maintain surface flatness during operation.
