摘要： In a method of producing molten pig iron from lumpy, iron-ore-containing charging substances, the latter are reduced in a reduction shaft furnace by means of a reducing gas, wherein the iron sponge particles obtained are melted in a melter gasifier under supply of coal and oxygen-containing gas under simultaneous formation of the reducing gas, and the reducing gas is returned to the reduction zone of the shaft furnace.To enable charging of larger amounts of fine ore and/or ore particles, such as oxidic iron fine dust incurred in a metallurgical plant, in addition to the charging substances, the fine ore and/or the ore dust is supplied with solid carbon carriers to at least one dust burner working into the melter gasifier and is reacted in a substoichiometric cumbustion reaction.

摘要： 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.
