SURFACE MELTING FURNACE AND METHOD FOR OPERATING SURFACE MELTING FURNACE

摘要

A surface melting furnace includes a furnace chamber 4, a treatment-target supply mechanism 8, and a plurality of sensors Hs and Ts. The furnace chamber 4 has a slag port 3a on its furnace bottom 3. The treatment-target supply mechanism 8 is configured to supply a treatment target to the furnace chamber 4. The sensors Hs and Ts are configured to perform measurement at different measurement locations for estimation of a profile of the molten surface of the treatment target, whereby the surface melting furnace enables the profile of the molten surface to be estimated over a large area. The treatment target supplied to the furnace chamber 4 by the treatment-target supply mechanism 8 is configured to melt from the surface and flow down to the slag port 3 a.
