Definitions

  • An apparatus for treating molten material including a wall which defines a chamber in which the molten material is to be treated, and which chambe r has a top opening. Pivot means turnably supports the wall for angular movement about a substantially horizontal axis. A source of coolant is provided. Distributing means is provided externally adjacent to the wall at least in the region of the top opening of the chamber for distributing coolant at least about the major part of the wall. Conduit means operatively connects the source with the distributing means for enabling supply of coolant to the latter.
  • the present invention relates to blast furnaces. More specifically, the invention relates to an arrangement for cooling the outer surfaces of such furnaces.
  • a still more specific object of the present invention is to provide such an arrangement in which cooling is performed by providing a continuous flow of water over the entire outer surface of the converter shell.
  • Another object of the invention is to provide an arrangement of the type described in which the formation and escape of mist are prevented.
  • one feature of my invention consists in the provision of a converter arrangement which includes the combination of a normally upright conveter having a wall and being formed ,with a top opening; turning means for enabling turning of the converter about a substantially horizontal axis;
  • water supply means water dispensing means arranged ing water onto the outer surface of the converter wall; water distributing means arranged about the outer surface of the Wall for distributing the cooling water substantially evenly over substantially the entire outer surface of the wall; conduit means operatively connecting the water supply means and the water dispensing means, and including first conduit means rigidly secured to the water supply means and second conduit means mounted on the converter for t urning movement therewith and communicating with the first conduit means for enabling supplying of cooling water to the water dispensing means even when the converter is not in its normally upn'ght position; and a receptacle arranged beneath the converter for reeeiving the cooling water.
  • the single figure is a partly-sectioned elevational View of a converter arrangement in accordance with the present invention.
  • the converter compromises a conventional shell 1 lined with refractory material 2 in the usual manner. Since the converter is of the normally upright type its charge and discharge opening 3 is provided at the normally upper end. The entire converter vessel is supported by means of hollow journal pins 4 in respective bearings 5 which rest on supports 6. Thus, the converter is tiltable about a horizontal aXis defined by the journal pins 4 by any suitable tilting means as indcated in the drawing.
  • the opening 3 of the converter is surrounded exter- V nally by a collector ring 7 into which the cooling water is fed in a manner which will presently become clear.
  • the collector ring 7 can, of course, be made in various diiferent forms and can be made integrally, assembled from individual sections, etc.
  • the inner surface of jacket 8 carries a plurality of preferably downwardly inclined baflles which serve to guide the flow of water in this space 8'.
  • Advanta-geously these baflies are staggered relative to one another with respect to both the circumference and the longitudinal axis of the converter.
  • a plurality of ribs Secured to the outer surface of shell 1 by any suitable means such as welding, serve to hold the jacket 8 in its predetermined position spaced from the shell 1 by a distance which advantageously ranges from 5-15 cm.
  • a plurality of circumferentially spaced pipes or hoses 11 are connected at their upper ends with the collector ring 7, as shown at 11', and communicate with the interior thereof. They extend downwardly along the outer surface of jacket 8 and their lower ends are connected in communicatin g relationship with an annular feeding conduit 12 which surrounds the converter at about its midpoint.
  • Valves 9 provided in the respective pipes or hoses 11 make it possible to shut off the flow of water through individual ones of the pipes or hoses 11 when such is desired, for example if only a portion of the refractory material is to be cooled.
  • the annular conduit 12 is connected with a longitudinal conduit portion or extension 12' which extends coaxially through one of the hollow journal pins 4- and whose outer free end communicates with a stationary conduit 14 by means of a short fiexible pipe or hose 13 interposed between conduits 12' and 14.
  • the pipe or hose 13 can be replaced with a watertight friction coupling of the type which would permit turning of the conduit extension 12' relative to the stationary conduit 14.
  • the stationary conduit 14 is connected with a coolant supply source (not shown) by means of a shut-off valve 15.
  • a shut-off valve 15 Intermediate the shut-off valve 15 and the feeding conduit 12' there is arranged another valve 16 which is normally closed and which can be opened when the supply of water through the valve 15 has been stopped and it is desired to evacuate water still remaining in the feeding conduit 12, 12'.
  • the jacket 8 At its bottom end the jacket 8 is provided with a dis charge opening 17 and a valve or other closing devicesuch as relatively rotatable discs with alignable bores-which permits the outflow of water through the opening 17 to be regulated. Downwardly of the opening 17 there is arranged a receptacle, such as a funnel 19, which receives water flowing through the opening 17 and leads this water into the discharge pipe 21 which carries it away. It will be understood that the regulating device 18 is provided so that the water level in the space 8' can be adjusted. This is of importance, since cooling of the bottom portion of the refractory material can obviously be achieved only by providing a water-bath, that is by having the bottom portion of the shell 1 continuously immersed in water.
  • the water should not rise into that portion of the space which surrounds the side wall of the converter, since this portion can be best cooled by a constant stream of water, and therefore there are provided overflow pipes 20 which will carry off the excess water if it rises above a predetermined level, and will deliver it to the receptacle 19.
  • annular conduit 12 ⁇ can be connected with the water supply by two extensions 12' which each pass through one of the pins 7. It is also possible to connect the hoses or pipes 11 directly with the collector ring 7 so that the need for letting the extension 12' pass through the pins 4 is eliminated. Also, the ribs which space the jacket 8 from shell 1 may be advantageously so construoted, for instance as a hollow triangle having its open base facing the converter, that they compensate for expansion of the shell 1.
  • valve 15 may also construct the valve 15 as a solenoid valve and so electrically connect it with the oxygen lance of the converter that valve 15 is open and permits the flow of water only when the lance enters into the converter. It needs no elaboration that the cooling action is primarily required when the lance is in the converter, that is when oxygen is blown into the vessel and the heat is most intense. In this embodiment the flow of water would then stop as the lance is removed from the vessel.
  • the inventive arrangement serves to achieve the desired cooling of the refractory material, and thus to achieve considerable economies with respect to consumption of such refractory material and also in decreasing the work required for maintaining the converter, namely relining the same.
