BEHOLDER FOR EN METALLSMELTEOVN, SPESIELT EN ELEKTRISK LYSBUEOVN

摘要

A vessel for a metal smelting furnace is disclosed. The vessel is provided with a heat-resistant interior wall and means for cooling the portions of said interior wall above the smelting zone. In accordance with the invention, the cooling means comprises an interior wall at least partially formed by at least one cooling pipe coil wherein the coil includes thick-walled pipes and neighboring sections of the coil are arranged in a closely adjacent relation. A cooling medium such as water is fed through the pipe coil under high pressure to dissipate heat from the interior wall of the vessel.
