Definitions

  • ABSTRACT 266/41 A method of bondin h 11 d g a 1g ensity, low-porosity, [51] f 5/00 F161 9/14 Czlb 7/16 abrasion-resistant, ceramic liner in a metal tube, such [58] held of 6 1 4 ?f l?g5 'gb l3f as a tuyere or an oxygen lance.
  • the method comprises j applying a sodium silicate-refractory aggregate cement 161/207 266/34 110/1825 156/325 to one of the surfaces to be joined, and inserting the 294 liner in the tube.
  • the cement need not be dried, as it 5 6 R f does not run. Therefore, the tube can be used immedi- 1 UNTEI; s zfA g s ggENTs ately, even in high-temperature applications.
  • Oxygen is injected into the steelmaking furnace through the central tube of the tuyere, and a jacket gas, which can be an inert gas such as argon or nitrogen or a hydrocarbon such as propane, butane, methane or natural gas is injected through the annular space formed by the central and outer tubes.
  • a jacket gas which can be an inert gas such as argon or nitrogen or a hydrocarbon such as propane, butane, methane or natural gas is injected through the annular space formed by the central and outer tubes.
  • Such flux particles are entrained in oxygen and are blown either into the bath of molten metal through a tuyere in a bottom blown converter or onto the surface of the bath through an oxygen lance in a top blown converter.
  • the term tuyere is used in this specification to mean tuyere or lance.” These flux particles can cause early erosion of the tuyere. It is, therefore, desirable to include a liner of a low-porosity, high-density, abrasion-resistant ceramic material within the tuyere.
  • an alumina tube has been installed in the metal tube of the tuyere and bonded thereto with a colloidal silica adhesive.
  • This adhesive necessitated placing the colloidal silica under pressure.
  • the adhesive must have been completely dried before the tuyere was used. If the adhesive was not completely dried, this adhesive, which is a flowable material, would flow from between the ceramic liner and the metal tube, leaving the ceramic liner free to be blown into the furnace when the oxygen was turned on.
  • F l6. 1 is a longitudinal sectional view of a dual concentric tuyere taken along line 1-] of FIG. 2.
  • FIG. 2 is a cross-sectional view of a dual concentric tuyere having a ceramic liner in the central tube of the tuyere, taken along line lI-ll of FIG. 1.
  • the drawings show a dual concentric tuyere which comprises a stainless steel outer tube 10 having nipples 12 which act as spacers, and stainless steel inner tube 13.
  • the inner tube has a ceramic liner 14 of a low po rosity, abrasion resistant ceramic material, such as alumina or mullite. These materials have a very low porosity approaching zero.
  • the liner is held in tube 12 by a layer of cement 16.
  • a cement which by weight consists essentially of about 1 to 10 percent alkali metal silicate mixture and 90 to 99 percent refractory aggregate.
  • the preferred range of alkali metal silicate is from 3 to 6 percent, the balance being refractory aggregate.
  • the preferred alkali metal silicate is sodium silicate, although we can use lithium or potassium silicate.
  • the ,Miwecmtent by weight ma ran 5 ercent, an t e silica content about 24 to percent, the
  • the sodium silicate is water soluble, and it may be either in powdered or liquid form, i.e., water glass.
  • the sodium silicate is mixed with an alumina-silica refracto agg regate, such as calcined clay, raw glay, kyanite, mul b u u i tures thereof.
  • the aggregate should have a thermal expansion that approximates that of the ceramic liner.
  • the particle size of the refractory aggregate must be 20 mesh and preferably will be l0O mesh.
  • the percentages of sodium silicate and aggregate are on a water free basis, that is, are measured prior to adding water to obtain a trowelable consistency.
  • Ceramic liner 14 is installed in tube 12 by applying an excess of the prepared cement to one of the two surfaces to be joined, that is, to the exterior surface of the ceramic liner or to the interior surface of the metal tube. The ceramic liner is then inserted into the tube in a manner to effect substantially complete contact of the cement with both of the surfaces being joined. We have found that insertion with a rotary motion will effect such substantially complete contact.
  • the consistency of the cement being such that it does not run, the tuyere may be used immediately after it is installed in a furnace, or the liner may even be installed in a tuyere which has already been installed in a fumace, and used immediately, even at high temperatures. However, inasmuch as there is no requirement that the tuyere be used immediately, it may first be dried, if desired.
  • the external diameter of the ceramic liner need not be within any particularly close tolerances.
  • the cement layer can be as thick as or even thicker than the thickness of the ceramic liner.
  • a composite tube comprising a metal tube, a highdensity, low-porosity, abrasion-resistant ceramic tube substantially concentric with said metal tube. a refractory cement layer between said tubes bonding said tubes together, said cement consisting essentially by weight of:
  • a composite tube according to claim 7 wherein said sodium silicate mixture has a sodium oxide content of from 22 to 32 percent and a silica content of from 50 to 60 percent.
  • a tuyere comprising:
  • / aggregate which has a particle size of about mesh and is selected from the group consisting of l j calcined clay, raw clay, kyanite, mullite, bauxite, J alumina and mixtures thereof.
