| 摘要 |
The invention relates to reverberatory furnaces used to operate upon baths of light metals, non-ferrous metals and alloys thereof. Reduction of wear on furnace walls, of energy used during operation and of dross formation on the metal bath, is achieved by a furnace (11) with a container (12) and roof (13) which form a shallow heating chamber (37) above the bath surface. A burner (14) directs a tight flame (39) to impinge against the bath surface.
