device for the determination of the surface profile of a furnace bed and melting tank process for monitoring the evolution of the profile

摘要

The surface contour of material deposited on the hearth of a furnace is sensed by measuring the height of the material on the furnace axis and at a plurality of points about the periphery of the furnace. The height on the furnace axis is measured with an instrument mounted on the axis of a furnace having an internally mounted steerable material distribution chute with the instrument being positioned vertically above the chute and the feed channel through which charge material is delivered to the chute.
