Definitions

  • This invention relates generaly to refractory linings and more particularly concerns a medium weight abrasion- resistant castable which may be used as a refractory lining.
  • Oil refineries use a significant amount of refractory linings comprising a dual castable lining having a dense abrasion-resistant working face and an insulating back-up.
  • the dual castable is formed from two separate bodies which are held together by the anchoring system when the steel shell is lined.
  • the insulating material is initially applied to the steel shell and then the dense abrasion- resistant material is applied to form the working face of the lining.
  • the dense abrasion-resistant face extends the life of the lining, but since its thermal conductivity is not sufficiently low, there must be an insulating layer behind the working face. Although such a refractory lining is adequate, since two layers must be installed, the time required to line the steel shell is significantly greater than if a single layer of castable material were used.
  • the prior art has used a single dense abrasion-resistant lining.
  • the refractory linings of the prior art have had to sacrifice the insulating value of the lining due to a higher thermal conductivity of the abrasion-resistant hard aggregate material used. Further, the density of the material makes it more difficult to hold the lining against the steel shell.
  • an "Insulating Castable” does not exceed a maximum bulk density of 105 lbs/cu ft (1.7 gr./cc) .
  • Commonly used abrasion-resistant products generally referred to as dense castables have a density which is generally greater than 130 lbs/cu ft (2.1 gr/cc) after being dried at 220°F (93°C).
  • the term "medium weight” is used to describe a castable having a density of between 105 and 130 lbs/cu ft (1.7 and 2.1 gr/cc).
  • the principle object of the present invention is to provide a medium weight abrasion-resistant castable for use as a refractory lining.
  • a further object is to provide such a castable having a bulk density of less than 120 lbs/cc ft (1.95 gr/cc), and abrasion loss of less than 20 cc and a thermal conductivity of less than 5.5 BTU/hr/ft 2 /in/°F (3.8 Kcal/min/cm 2 /cm/°C) .
  • the objects are accomplished by providing a castable in which the coarse aggregate has been substituted with a raw material which may not be as hard as the currently used coarse aggregate but has a better insulating value to decrease the thermal conductivity of the castable without an increase in abrasion loss.
  • a raw material which may not be as hard as the currently used coarse aggregate but has a better insulating value to decrease the thermal conductivity of the castable without an increase in abrasion loss.
  • a material is cordierite which is a synthetic mineral found in saggers for setting whiteware during firing.
  • a desirable medium weight abrasion-resistant castable has the following properties:
  • CCS CCS
  • MOR 1500°F or 815°C
  • Linear change (1500°F or 815°C) is the percent change in length of a rectangular shaped specimen having an initial length recorded after the same specimen has been fired to 1500°F (815°C) and cooled to room temperature.
  • An allowable linear change of -0.5% means that the maximum allowable shrinkage is 0.5%.
  • Abrasion resistance also known as erosion loss, is measured in accordance with ASTM-C-704 Abrasion Resistance of Refractory Materials at Room Temperature.
  • the coarse aggregate should have a density of less than 120 lbs/cm ft (1.95 gr/cc).
  • Cordierite having a specific gravity of 2.57-2.66 g/cc and a hardness of 7.0-7.5 Mohs in natural occurrence is such as material.
  • cordierite is scarce in natural occurrence, synthetic cordierite is found in sag ⁇ gers used to set whiteware during firing.
  • the saggers were found to contain cordierite and mullite as major phases with quartz as a minor phase. It is the cordierite in the saggers that result in reduced thermal conductivity with ⁇ out significantly increasing abrasion loss.
  • the bulk density of the saggers in less than 120 lbs/cm ft (1.95 gr/cc) .
  • the saggers After the saggers begin to crack excessively, they are discarded and used as land fill. Therefore, not only do the saggers containing cordierite have the desired properties, but it is an inexpensive raw material. Other synthetic bodies containing cordierite may also be used in this product.
  • the saggers To form the coarse aggregate of cordierite, the saggers must be crushed and sized by passing through a screen of proper mesh.
  • composition range and preferred composition for a medium weight abrasion-resistant castable having the desired properties is listed below:
  • composition Range Percent Composition (Percent by Weight) By Weight
  • 6x20M means a grain size which will pass through a Tyler standard screen having a mesh desig ⁇ nation of 6 mesh and not pass through a 20 mesh
  • the cordierite supplied and used in the composition is approxi ⁇ mately 95% 6x20M with the remander being an aggregate of a smaller size.
  • a typical grain size distribution is as follows:
  • Tyler Mesh +4 means a grain size greater than Tyler Mesh 4, i.e. greater than 0.185 in (0.47cm).
  • Tyler Mesh -4+6 means a grain size less than Tyler Mesh 4 and greater than Tyler Mesh 6.
  • calcined kaolin also known as calcined clay
  • cordierite having a size of 20 mesh or less does not achieve the necessary abrasion resistance due to the lower hardness value of cordierite and because cordierite has a higher water absorption which requires more water to form the castable and therefore creates more porosity.
  • Other known refractory materials such as calcined flint or fused silica may be used in place of the calcined kaolin.
  • the calcined kaolin may be obtained from C-E Minerals under the tradename Mulcoa 47.
  • Mulcoa 47, 20 mesh and Mulcoa 47, 100 mesh have the following grain size distri ⁇ butions:
  • the density of the castable would be increased. This increase may be offset by using a greater amount of fly ash ceno- spheres.
  • a smaller grain size cordierite may be used. However the use of intermediate and finer grain size cordierite results in a softer, more porous matrix.
  • the fly ash cenospheres are hard, lightweight inter ⁇ mediate grains having a bulk density of 24 lbs cu ft (0.4 gr/cc) and a particle size of approximately 48-400 mesh.
  • the use of the fly ash is necessary to reduce the bulk density of the castable.
  • the cenospheres also improve the plasticity of the mix. Use of the fly ash does reduce the abrasion resistance, but is necessary to reduce the bulk density and maintain a low thermal conductivity.
  • the fly ash cenospheres may be obtained from Fillite U.S.A., Inc. under the tradename Fillite 52/7/S. Other aggregate having similar hard, lightweight intermediate grains may be substituted for the fly ash cenospheres .
  • the clay and fume silica are added to the composi ⁇ tion to give a wide water range and add plasticity to the mix for better placement.
  • the air floated clay is a reduced size fine clay.
  • Ultrafine fume silica has a size of less than 50 microns and preferably less than 1 micron.
  • Plasticizers may be used in place of the air floated clay. These fine particles fill the smaller pores in the mix thereby improving mechanical packing and abrasion resis ⁇ tance.
  • the fine particles may be a combination of air floated clay and ultrafine or either floated clay or ultrafine alone.
  • the air floated clay may be obtained from Kentucky-Tennessee Clay Company under the tradename KT #6 and the fume silica from Interlake, Inc. under the tradename Globe Fume.
  • the binder may be a high purity calcium aluminate cement or other known cement.
  • High purity calcium alumi ⁇ nate cement may be obtained from Lone Star LaFarge under the tradename Secar 80 or from Alcoa under the tradename CA-25.
  • the typical properties of the medium weight abrasion resistant castable having the preferred composition are as follows:
  • the castable meets the requirements which have been set and are in demand by the industry.
