Abstract
A plant for metallurgical treatments, in particular for melting or melt-reducing metals, metal compounds and/or metal alloys, or for producing calcium carbide, comprises a shaft receiving a burden, a melt collecting space disposed laterally of, and below, the shaft, as well as at least one burner arranged laterally of the shaft. In order to enable the accurate process control of the metal melt and the controlled smelting of the burden, the burner is arranged in a combustion space connecting the lower shaft end with the melt collecting space and designed as a plasma burner. The combustion space is located at a level above the melt collecting space and including a combustion space bottom, which is plane, or preferably rises, relative to the shaft and enters into the melt collecting space by an overflow edge that separates the metal melt from the burden.
