Definitions

  • a wall structure particularly adapted for furnaces that are lined with insulating or refractory blocks, in which an outer metal shell has a plurality of parallel support bars secured to its inner surface, the bars being spaced inwardly from the inner surface of the shell, and a plurality of U-shaped block retainer pins are supported with the base portions thereof between the shell and the support bars.
  • the retainer pins have arm portions extending away from the shell between adjacent blocks and spaced apart sufficiently to permit limited movement of the pins transversely of the support bars.
  • the base portions of the U-shaped pins are movable both longitudinally and transversely of said support bars between the bars and the outer shell.
  • Adjustable locking means are mounted on the ends of the arm portions of the retainer pins, which extend beyond the inner faces of the lining blocks, and are movable on the arm portions to engage the faces of the adjacent blocks and hold the blocks against the support bars while permitting limited relative movement between the blocks and the support bars caused by expansion and contraction of the blocks, bars, or shell.
  • a metal outer furnace wall or shell is provided which is lined with suitable insulating or refractory material in the form of blocks or bricks.
  • suitable insulating or refractory material in the form of blocks or bricks.
  • FIGURE 1 is a fragmentary perspective view of a portion of a refractory block lined furnace wall structure in which my block retaining means are employed to secure the blocks in position and to facilitate resetting thereof after initial shrinkage.
  • FIGURE 2 is an enlarged fragmentary view of a portion of the wall shown in FIGURE 1 illustrating the block support bars and block retainer members in greater detail.
  • FIGURE 3 is a vertical cross-sectional view taken substantially on line 3-3 of FIGURE 2 and drawn to a somewhat enlarged scale.
  • the furnace floor or base is indicated at B and the furnace outer wall or shell member, which is commonly formed of steel plate, is seen at W.
  • the furnace outer wall or shell member which is commonly formed of steel plate, is seen at W.
  • These bars are formed with longitudinally spaced offset pads 11: which, as clearly seen in FIGURE 2, are secured as by welding to the wall W.
  • the offset of the pads 1a is sufficient to space the bars 1 from the wall W a distance substantially equal to the diameter of the block retainer members R as will more fully appear later.
  • the furnace lining is made up of a plurality of individual rectangular liner blocks 2, the bottom row of which is supported on the furnace floor or base B and succeeding rows are laid up one upon the other with the vertical edges of the blocks of the several rows in alignment.
  • the bottom row of the blocks 2 is first positioned and as the individual blocks of successive rows are put in place a block retainer member or pin R is placed between the adjacent vertical edges of each pair of adjacent blocks.
  • the retainer members R are in the form of U-shaped clips or pins each of which has a base portion 3 and a pair of arm portions 4, of greater length than the thickness of the blocks 2, extending substantially at right angles to the base portion.
  • These retainer pins are slipped down between the wall W and a pair P of adjacent support bars 1. This is accomplished by laying a retainer R with its arm portions 4 parallel to and against the wall W and then pushing the unit down behind the pair of adjacent parallel support bars 1 in the manner illustrated in the lower right hand portion of FIGURE 1. After the retainer pin has been positioned behind the pair P of support bars it is rotated through so that the arms 4 thereof extend at right angles to the wall W.
  • the retainer member R then slid longitudinally of the bars 1 until it engages the vertical edge of the adjacent block 2.
  • locking means are secured on the outwardly projecting ends of the arms 4.
  • These locking means are pierced and slit dished self-locking washers 5 which are pushed inwardly onto the pointed projecting ends of the arms 4 until they overlie and engage the inner faces of the blocks 2 and force the inner faces thereof firmly against the support bars 1.
  • the form of these dished locking Washers is such that, while they may be moved easily inwardly on the pins or arms 4, they lock against outward movement at any position of adjustment due to the locking action of the inclined slotted tang portions 5a of the washers.
  • the support bars 1 are arranged in parallel pairs P.
  • the spacing apart of the bars making up a pair, and the spacing apart of the adjacent pairs of bars, is coordinated with the vertical dimensions of the blocks being installed.
  • a pair P of bars 1 is arranged symmetrically to the horizontal center line of each horizontal row of blocks 2.
  • the longitudinal spacing of the attaching pads 1a on the bars 1 is also coordinated with the width of the individual blocks 2 which make up the wall, this spacing being such that each U-shaped retainer pin R may have a limited amount of unrestricted horizontal movement relative to its pair of supporting bars P.
  • the base portions 3 of the retainers R are greater in length than the vertical spacing between the bars 1 of each pair P, limited unimpeded vertical movement of the retained units R may also occur.
  • the space between the bars 1 and the furnace shell W which is provided by the pads 1a is substantially equal to the diameter of the rod or wire stock making up the retainer members R and preferably is such that bars 1 will hold the retainers R in vertical position by frictional engagement therewith so that the retainers, when they are first positioned between adjacent blocks 2 during lay-up of the wall, will have their top arm member 4 supported above the adjacent bar 1. This is clearly seen in FIGURE 2 and the reason for this frictional support of the retainers R will appear later.
  • this clearance as well as any clearance at the ends of the rows of blocks after they have been reset laterally into proper engagement with each other, may be filled by suitably cut blocks, refractory cement, or the like and after resetting, the washers 5 are again pushed inwardly into firm engagement with the outer faces of the blocks to take up any reduction that may have occurred in the thickness of the blocks.
  • a Wall structure including a metallic outer shell member; a plurality of parallel pairs of parallel support bars secured at longitudinally spaced attaching points to the inner face of said shell member in inwardly spaced relation thereto; a plurality of rows of Wall lining blocks extending in the same direction as said support bars, said blocks being arranged in adjacent edge to edge relation and said rows of blocks being disposed one row in alignment with each of said pairs of support bars; a plurality of block retainer members comprising U-shaped pins each having a base portion retained between said shell member and a pair of said supporting bars and a pair of spaced apart arm portions extending from said base portion, the length of said base portions being greater than the distance between the parallel support bars of a pair and said arm portions being spaced apart sufficiently to permit limited movement of said retainer members transversely of said pairs of support bars, the length of said arm portions of said retainer members being greater than the thickness of said lining blocks; and locking means comprising self-locking washer members freely slidable on said arm portions in a direction toward said lining blocks
  • a wall structure as defined in claim 1 in which said spaced apart arm portions of said U-shaped pins extend between the edges of pairs of adjacent blocks of a row of blocks and said locking washers on said arm portions each overlies the inner faces of the pair of blocks between which the arm extends and retains said blocks in position in the wall structure.
