Definitions

  • the invention relates to a cooling element for with a refractory lining shaft furnaces, in particular Blast furnaces consisting of copper or one low-alloy copper alloy with inside arranged coolant channels.
  • Cooling systems for the tank of shaft furnaces, in particular Blast furnaces are in "Stahl und Eisen", 106 (1986), No. 5, pages 205-210, described in detail.
  • cooling with so-called cooling boxes in recent years cooling with cooling plates, so-called staves, always made of cast iron and copper enforced more.
  • 25 280 is a cooling plate made of gray cast iron known in which the cooling channels through cooling pipes were formed, which were poured into the cast body were.
  • the disadvantage here is that to avoid the Carburizing requires a coating of the cooling pipes which is the heat flow from the hot side of the cooling plate or the staves through the stave body and the pipe wall to the cooling water. Staves like that therefore often reached high temperatures at which a Pearlite decay occurs (> 760 ° C); it formed Cracks in the cast body, and after a relatively short time Operating time is the casting material in front of the cooling pipes worn away.
  • the so-called Copper staves are known from DE 29 07 511 and are made from rolled copper material, the cooling channels through deep hole parallel to Hot side. This creates an undisturbed, not impeded by any pipe coating Heat flow reached.
  • Such copper staves are on its hot side much colder than Staves made of gray cast iron, so that - unlike with gray cast iron Staves - there is one stable crust from furniture material that acts as insulation works. It so happens that, despite the high thermal conductivity of this material from one Blast furnace dissipate less heat than gray cast iron staves.
  • Another advantage of the copper staves is that these are structurally thinner (approx. 150 mm) can be cast iron staves (approx. 250 mm). Given a Blast furnace profile increases the usable volume The use of copper staves is therefore considerable.
  • a disadvantage of the known copper staves is that these are still relatively massive and so are heavy and expensive.
  • the processing effort is due to the all-round mechanical processing, the Milling grooves, deep hole drilling and through that Welding the pipe connections considerably.
  • the Machined material makes up a significant part of the Total weight and only becomes significantly less Price withdrawn.
  • Another disadvantage is that certain channel diameters when drilling deep holes over a depth of 2 - 3 m must not be undercut because otherwise there is a risk that the drill will run.
  • the resulting cooling channels are larger than required; the same applies to the amount of cooling water, since a minimum speed of approx. 1.5 m / sec required is to at high thermal stress to remove any steam bubbles that may be forming on the pipe wall.
  • the cooling water heating rates are therefore uneconomical low.
  • the object of the invention is, in contrast to the well-known copper staves both the material and to reduce the processing effort considerably and still a stable, the rough demands in the blast furnace operation to create grown cooling element that itself can be assembled with little installation effort and one Lifetime in at least the same order of magnitude as has a blast furnace system.
  • Another object of the invention is to suitable design of the Flow cross section for the cooling water to higher Heating rates for the cooling water to arrive without therefore the minimum speed required for to fall below the cooling water that is necessary to at high thermal loads on the pipe wall detaching forming vapor bubbles and transporting them away.
  • the hot side is designed so that with little effort results in a surface on which Crusts from furniture material can adhere well.
  • a conventional Cu cooling element usually has four has parallel cooling channels in a copper block run parallel to the hot side
  • a Cooling element according to the invention from a suitable chosen length of an extruded or rolled Cu profile, which is one or more round or of contains cooling channels deviating from the circular shape.
  • the extruded or rolled profile both sufficient rigidity brings with it, through which the rough demands of the Endured blast furnace operation; this applies in particular on the or the fastening ribs on the Cooling element on the side facing the furnace Side are arranged. They also serve for Fastening the cooling element to the blast furnace shell.
  • the Side webs lying parallel to the blast furnace shell of the copper cooling elements ensure a comprehensive coverage Protection of the blast furnace shell. Your width will be like this determined that they are with the appropriate web of the neighboring element overlap or finish flush. This also makes the diameter or circumference differences in conical parts of the blast furnace (Rest, shaft) balanced.
  • the inside of the oven protruding slag ribs on the hot side are through mechanical postprocessing designed so that the Formation and stable adhesion of a layer solid or doughy stuff on the hot side of the Lighten copper cooling elements.
  • the copper cooling elements can be installed close to the construction site cut to the correct length and bent become.
  • the individual copper cooling elements through the side webs Sawing, abrasive cutting or burning separated or removed, the remaining circular or non-circular Channel cross-section bent accordingly and through the Corresponding passage opening in the blast furnace tank guided.
  • Via intermediate pipe sections for the cooling water flow the cooling elements to the cooling circuit connected to the blast furnace.
  • the one in the furnace and outside Duct cross section back to the cold deformation round cross section.
  • Cooling elements Holes in the ribs running towards the tank; in these ribs grip attached to the blast furnace shell Support elements; the connection between the ribs and the support elements are made, for example, by inserted secured dowel pins or bolts. After the mechanical assembly takes place in a known manner a backfilling of the Cu cooling elements with a low heat-conductive refractory mass.
  • Cooling element does require a slightly larger one Material and manufacturing costs due to the Joining the box profiles and manufacturing the foot and head pieces, but it is even flatter than the Cu cooling elements with the pipe cross section or sections as well as the attached ribs and can therefore be largely adapted to the curvature of the furnace wall.
  • the attachment to the furnace wall can be done conventionally Blind holes with threads in the cooling element and through mounting screws going through the furnace done by welded on the outside Cover caps are made gastight.
  • Fig. 1 shows a cross section through a cooling element (1) from an extruded or rolled profile section, the inside one or more round or of elongated cooling channels deviating from the circular shape (2) contains.
  • the cooling element (1) is provided with lateral webs (3) provided on the of the blast furnace wall (9) opposite side and continuous in the vertical direction Slag ribs (4) arranged. On the the Blast furnace wall (9) facing side is one Fastening rib (5) arranged.
  • the cooling element (1) is screwed in by means of bolts (7) Bores (6) of the fastener (8), the Blast furnace wall (9) and the fastening rib (5) attached, the space between the cooling element (1) and blast furnace wall (9) is with a refractory backfill (10) filled out.
  • the top and lower webs (3) and the slag ribs (4) run still vertical and formed by recesses (18) each with the next cooling element covering the entire area Connection connection.
  • the attachment to the Blast furnace wall (8, 9) is carried out by a bolt (7) through the fastening rib (5) and the fastening element (8) is performed.
  • FIG. 3 shows a longitudinal section of the cooling element (1) with the oval cooling duct (2).
  • the webs (3) are arranged on both sides of the cooling channel (2).
  • the fastener (8) the side of the blast furnace wall (9) an elongated fastening rib (5) is provided on the fastener (8) the side of the blast furnace wall (9) an elongated fastening rib (5) is provided.
  • Fig. 4 shows a top view of another alternative Embodiment of a cooling element (1) that a rectangular cooling element (11) with a groove and a rectangular cooling element (13) with spring, in each of which a cooling channel (12) is incorporated.
  • the cooling element (1) is by means of fastening elements (14) attached to the blast furnace shell (9). Between Cooling element (1) and blast furnace shell (9) becomes one ff backfill (10) introduced.
  • Fig. 5 shows a side view of one another on the Blast furnace armor (9) attached cooling elements (1, 11, 12, 13).
