Definitions

  • the -beams 2', 3' and '4', 5' consist of the longitudinal beams 2', 4' in which cooling water is flowing, individually supported by the vertical beams 3', 5' in which cooling rwater is likewise flowing, with the walking beam 4', 5' provided between adjacent fixed beams 2', 3' in the direction perpendicular to the movement of the material to be heated 1.
  • the material 1 is moved toward the discharging end by the forward movement of the base 9 after the material is lifted up from the Abeam 2' by the said base 9 integral with and supporting the walking beams 4', 5 when the base is raised upward. Then the base is lowered and goes back to its original position, leaving the material 1 on the beams 2.
  • the present invention relates to a walking beam type continuous heating furnace designed to eliminate the aforementioned disadvantages and characterized in that it comprises a suitable number of fixed beams and walking beams of compassion structure composed of a plurality of longitudinal beams provided in the direction of movement of the material to be heated and of vertical hairpin beams fixed thereto, said fixed beams and walking beams being arranged in plurality in the direction of movement of the material and at the same time said fixed beams and walking beams being provided in suitable numbers at a right angle to the said direction, thereby forming blocks, and the means for flowing the cooling water in only one direction inside the said beams.
  • FIG. 1l and 12 An embodiment of the walking beam type continuous heating furnace provided with the water sealing system of this invention is shown in FIG. 1l and 12 in the attached drawings by way of explanation of our invention.
