Definitions

  • the invention relates to an annealing material carrier for receiving workpieces that are treated in an annealing furnace.
  • Annealing material carriers for transporting the annealing material through an annealing furnace and also for quenching the annealing material in quenching liquid are exposed to large temperature fluctuations and local temperature differences, so that they suffer high thermal voltages.
  • Different types of annealing material carriers are required for different annealing materials.
  • Individual or larger workpieces can be placed on a simple grate that runs through the annealing furnace. Smaller parts are placed in heat treatment baskets, lined up or poured loose. Single or larger workpieces can also be placed in baskets to be in the annealing furnace to be treated.
  • Such incandescent baskets are known from EP 0 015 373 B1 or EP 0 193 649 B1.
  • incandescent baskets have a bottom grate with peripheral edge strips and side frame parts, the vertical struts or columns of which are molded onto the bottom grate.
  • Individual struts or areas of the side frame parts can be connected to the floor grate in a manner such that they can be stretched, but in general the struts and the side frame parts are always formed in one piece with the floor grate.
  • the receiving space of such annealing baskets is lined with a wire mesh, the mesh size of which is dimensioned such that the annealing items cannot fall through.
  • annealing material carriers In the manufacture of annealing material carriers, there are different types of annealing material carriers corresponding to the respective annealing material, each of which requires its own construction. Annealing goods carriers that only consist of a floor grate are produced according to their own criteria and with separate forms. Annealing material carriers, which are designed as annealing baskets, require other constructions and casting molds. The manufacturers of annealing material carriers must therefore be able to manufacture and keep numerous different types of annealing material carriers in stock.
  • the invention has for its object to provide an incandescent material carrier which simplifies the production outlay for different types of annealing material carriers.
  • the annealing material carrier according to the invention has a one-piece floor grid made of cast material, which is free of side frame parts, but has brackets for attaching such side frame parts. It is therefore possible to use the floor grate itself, that is to say without side frame parts, as an annealing material carrier. There is also the option of retrofitting side frame parts to the floor grate. In this way, a large variety of types of annealing material carriers can be produced on the basis of a uniform floor grid.
  • the side frame parts can, if necessary, be attached to the floor grid, so that a glow basket is formed.
  • the side frame parts which differ, for example, by its height or by other characteristics, can be where 'a particular type of side frame members used in conjunction with dem ⁇ same bottom grid either.
  • the manufacturer of annealing material carriers produces the floor grille as a standard part and then adds the side frame parts according to the respective customer orders, or he leaves the floor grate free of side frame parts.
  • the same floor grate which can be used for different types of annealing material carriers, thus enables typing or standardization.
  • Floor grates can be produced in large quantities and only then processed into the desired type of annealing material carrier.
  • the annealing goods carrier is designed as a basket, several baskets can be stacked one above the other and one below the other be pluggable.
  • the stack height is limited by the dimensions of the furnace. It is possible to set up and stack baskets with a height that differs from the height of the stackable and stackable baskets.
  • connection points or nodes are provided in the corners of the floor grating, which can accommodate screwable columns. These columns support the upper baskets with the help of cylindrical spacer sleeves with which the height of separation between the baskets can be adjusted.
  • the brackets are designed such that they engage with the side frame parts with play and allow expansion displacements.
  • the annealing material carrier according to the invention allows numerous variations.
  • the annealing material carrier is designed as an annealing basket
  • one of the side walls can be pulled off upwards, so that the annealing material can be poured out for emptying the annealing basket.
  • the floor grate can have fastening means for releasably attaching support columns for storey structures.
  • the side frame parts can either have frame or lattice structures, but it can also be closed or perforated walls.
  • Those side frame parts which are permanently connected to the floor grate preferably consist of side rails and columns projecting therefrom, the ends of which are fastened to the holders of the floor grate.
  • FIG. 2 shows a section through the floor grate along the line II-II of FIG. 1 with edge strips attached to the floor grate
  • FIG. 5 is an enlarged view of the detail V from FIG. 1,
  • FIG. 6 shows a top view of a corner of the floor grating with a column fastened thereon and a removable side wall part
  • FIG. 8 shows a section through the floor grate along the line VIII-VIII of FIG. 1, with support columns for floor structures attached to the floor grate, and
  • FIG 9 shows a vertical section through a stack of several baskets placed one above the other.
  • the floor grate 10 shown in FIG. 1 is a one-piece cast part made of steel.
  • the floor grate 10 is made from a grid of longitudinal strips 11 and transverse strips 12, cylindrical knot elements 13 having a central hole being present at the intersections.
  • the floor grate 10 is delimited by longitudinal edge strips 14 and guer Surpriseder edge strips 15.
  • the longitudinal strips 11, the guer ⁇ strip strips 12 and the edge strips 14 form a flat support surface on which annealing material can be placed.
  • the guer running edge strips 15 protrude slightly beyond the contact surface. These edge strips 15 form stop strips on which two floor gratings, which are conveyed in the longitudinal direction on a conveying path, can abut one another.
  • brackets 16 are provided below the support surface, at which the lower ends of side frame parts can be attached.
  • the brackets 16 are closed rectangular eyelets which merge centrally into the respective strip 11 or 12 and which are each delimited by an edge strip 14 or 15.
  • the strips 11 and 12 therefore do not directly meet the edge strips 14 and 15, but rather branch out in the holders 16 shortly before these edge strips.
  • the openings of the holders 16 are vertically continuous.
  • fastening means 17 are also provided for attaching support columns for storey structures. These fastening means are arranged in the fields of the lattice structure consisting of the strips 11 and 12 and are integrally formed on the floor grid. They have vertical tapped holes.
