摘要
In order to be able to process in an economical manner different iron carriers in varying quantitative compositions, a plant for the production of iron melts (4), in particular steel melts, such as crude steel melts, is equipped withan electric are furnace vessel (1),a refining vessel (3) following upon the furnace vessel (1) via a weir (34) and including a bottom departing from the weir (34) in an at least partially downwardly inclined manner and an oxygen supply means (35, 36) as well as an iron melt tap (41) provided in its end region farther remote from the furnace vessel (1),a decanting vessel (2) following upon the furnace vessel (1) and having a common bottom (18) with the furnace vessel (1), said decanting vessel being provided with a slag tap (43) in its end region farther remote from the furnace vessel (1),a supply means (21) supplying liquid pig iron (20) and opening into the furnace vessel (1),a preheating shaft (5) supplying solid iron carries (7), said preheating shaft being arranged above the furnace vessel (1) and opening into the furnace vessel (1) via its lid (4) via a gas-permeable cooled shut-off means (6), anda charging shaft (10) arranged above the furnace vessel (1) and opening into the furnace vessel (1) via a gas-impermeable cooled shut-off means (11) (FIG. 1).
