Abstract (en)
[origin: EP0512658A1] The invention relates to plant for the secondary metallurgical treatment of molten steel, which is arranged within a production chain consisting of a melting device, such as an electric furnace or converter, and a casting device, in particular a continuous casting device. A solution is to be found which, at the lowest possible cost, ensures a high degree of flexibility and an adaptation of the VOD transformation time to the cycle times of the upstream and/or downstream melting and casting devices. For this purpose, the plant is designed with two stands for in each case one vessel (1, 1') which can be evacuated and contains a steel melt, which contain devices (6, 6') for feeding oxygen and devices (7, 7') for adding additives to the melt, and with pipes (3) which connect the vessels (1, 1') to a device for generating a vacuum, a device consisting of a water ring pump station (5') for generating a moderate vacuum and a device (4, 5) consisting of water ring pumps (4) and steam ejectors (5) for generating a deep vacuum being provided, and the vessels being selectively connectable only to the device for generating a moderate vacuum (5') or to the device for generating a deep vacuum (4, 5). <IMAGE>
