Definitions

  • the invention relates to a gas supply system and an operating method for such a system for a side and / or bottom-blowing metallurgical furnace, in particular a converter for the production of carbon steels or stainless steels, having at least one nozzle which is arranged in the furnace side wall and / or in the furnace bottom , wherein gas is conveyed via a line to the nozzle and through the nozzle into the interior of the metallurgical furnace.
  • AOD argon oxygen decarburization
  • converters with bottom nozzles are also used for other steel grades.
  • the nozzles are exposed to different mixtures of oxygen and argon.
  • the nozzles are in blow position of the converter below the metal bath level.
  • a phenomenon occurs which has become known in the literature as a "back-attack" and has been detected by high-speed photography.
  • Fig. 5 shows here schematically on the basis of 5 stages the individual time sequences when entering a gas jet into a molten metal and the "back-attack" effect.
  • the gas jet 101 from the horizontal nozzle 102 enters the molten metal 103 approximately horizontally ( Fig. 5 , Drawing 1).
  • a gas bubble column 104 is formed.
  • a further expansion of the gas bubble takes place into the interior of the molten metal 103 (partial image 2).
  • a constriction 105 occurs at the "stem” of the gas bubble and a "collapse” (part of image 3), and finally the gas bubble 106 is detached in large format (partial image 4).
  • the gas jet 101 bounces against the wall of the cavern formed of liquid metal and is deflected in the direction of the existing of refractory material converter wall 107, which is the actual "back-attack".
  • sub-picture 5 the same state is achieved as in sub-picture 1, and the sequence is repeated.
  • the large volume of the stripping gas bubble results in an unfavorable, i. small, surface volume ratio.
  • the reactions between gas and molten metal therefore proceed more slowly, the utilization of oxygen in particular is inferior, the mixing effect between molten metal and the slag floating thereon is poor.
  • the required process gas quantities are higher and the operating costs less favorable.
  • the present invention seeks to mitigate or eliminate the "back-attack" effect in metallurgical furnaces, the above-mentioned disadvantages should not occur.
  • the gas supply system of the metallurgical furnace has an inlet throttle device which is arranged upstream of the nozzle and which periodically reduces or interrupts the gas supply into the furnace interior. This ensures that in much shorter time intervals than in the conventional uninterrupted gas flow, the gas bubble can detach from the nozzle tip. This results in smaller bubbles from the beginning, and the repercussions of the back-attack on the vessel wall are much smaller. At the same time, there is a higher surface-volume ratio of the gas bubbles.
  • the gas flow in the oven interior with frequencies above about 5 Hz periodically reduced or interrupted and thus the gas stream is divided into smaller volume units. It has been found that from a frequency of about 5 Hz switching frequency of the inflow throttle, there is a significant reduction of the maximum pressure amplitudes at approximately the same frequency. This favorable reduction of the pressure amplitudes can be amplified with increasing switching frequency with very favorable results at a switching frequency of for example 20 Hz and higher.
  • the inflow throttle is arranged in the gas supply line to the nozzles and as close to the nozzle exit.
  • any type of inflow throttle or aggregates for gas flows can be considered.
  • a device of a mechanical nature is proposed, preferably a solenoid valve or a servo valve.
  • the arrangement of the inflow throttle devices should preferably be made so that they can be bypassed.
  • the system has lockable bypass lines which are integrated with the respective lines Inflow throttle device are assigned. Then it is possible, in certain blow phases, for example in low blow rate phases where the back-attack effect is less pronounced, to direct the gas flow only through the bypass ducts and to dispense with the regulation by the inflow throttles. At the same time, the operation can be continued with failure of one or more of the inflow throttle devices with such an arrangement.
  • Fig. 1 schematically shows the example of a converter 1 with refractory lining 2 an inventive gas supply system 3 for reducing or preventing the "back-attack" effect.
  • a converter with side nozzles a plurality of (immersion) nozzles are used on the converter wall, which lie below the bath surface 4 after the vertical position of the converter 1.
  • Fig. 1 For example, only one of the nozzles 5 is shown.
  • the nozzle 5 extends horizontally through the refractory lining 2 of the furnace.
  • the nozzle 5 is part of the gas supply system 3, which also has gas lines 6, in each of which an inflow throttle 7, here a solenoid valve or a servo valve, is integrated. This inflow throttle 7 is arranged as close to the nozzle exit.
  • the gas supply to the interior of the furnace or the molten metal is periodically or regularly reduced or completely interrupted for a short time.
  • the gas supply system 7 each have bypass lines 8.
  • the respective bypass line 8 can be shut off or opened.
  • the inflow throttle 7 or the locking device 9 is then closed.
  • the control of the valve and the locking device 9 is taken over by means of a control device 10, which communicates with the valve and the locking device 9 via control lines 11.
  • a control device 10 By means of the control device 10, an adaptation of individual valves of adjacent supply lines for a plurality of nozzles and the blocking means of the bypass lines is controlled.
  • the Fig. 2 to 4 show results of model tests in a round water tank, in which the pressure surges (alternating pressure in bar) were measured on the vessel wall with a special sensor over the time in ms.
  • a round nozzle with a diameter of 6 mm was used with a nozzle pitch of 0 °.
  • the Nozzle shown with its radial areas of influence on the vessel wall.
  • the measuring sensor is located at point V1.
  • No-valve nozzles initially show the typical appearance of "back-attack" (cf. Fig. 2 ).
  • a pulsation frequency of 7Hz ( Fig. 3 ).
  • the best results were achieved with 20 Hz switching frequency, which simultaneously represented the maximum switching frequency for the solenoid valve used.
  • the voltage amplitudes of the back-attack become smaller.
