摘要： A method for two-stage melt reduction of iron ore, in which iron ore is prereduced substantially to wustite and at the same time melted down in a melting cyclone, and then liquid hot metal is produced in an iron bath reactor connected to the outlet of the melting cyclone and receiving the melted wustite by adding carbonaceous fuels and oxidizing gas to the melt. The resulting reaction gas from the melt is afterburned, and the dust-laden, partly burned reaction gases from the iron bath reactor are accelerated and further afterburned by adding a hot blast with a temperature of 800.degree. C. to 1500.degree. C., and at least a portion of such accelerated, after burned reaction gases are introduced into the melting cyclone to reduce and melt fresh iron ore.

摘要： The invention describes a method and a means for supplying nozzles comprising concentric pipes with gaseous and/or liquid hydrocarbons in which oxygen or oxygen-containing gases are simultaneously introduced into a converter. In so doing, the gases and/or liquid hydrocarbons are conducted through collecting pipes leading into distribution chambers. They are conducted from the distribution chambers through hydrocarbon volume control devices, which are integrally arranged along with the hydrocarbon distribution devices in a rotatable device element of the rotatable control unit, on to nozzle pipes. Then, the gaseous hydrocarbons are further conducted through a safety control member arranged downstream from the hydrocarbon volume control device. Thus, the even supply of gaseous and/or liquid hydrocarbons to the nozzles is ensured at highly varying throughput rates and alternate supply, in a manner which is simple and reliable.

摘要： An increase in the life of basic refractory linings in hearth type refining furnaces and a decrease in tap-to-tap time is achieved by the use of at least one refining tuyere which consists of two concentric pipes. The central pipe feeds oxygen into the melt below the bath surface, and a hydrocarbon stream surrounds the oxygen being fed into the bath, the hydrocarbon flowing in the space between the two pipes. Preferably the tuyere is embedded in the furnace backwall and is approximately horizontal and is directed toward the center of the hearth. By use of the double tuyere, oxygen can be used for refining without experiencing excessive refractory wear.
