ることにとどまる。Conventional technology and its problems For convenience, a conventional example will be explained using FIG. 1. The refractory partition wall 4 is narrowed inside the hearth refractory 2 (! Fixed in condition, refractory partition wall 4
The material is composed of a monolithic refractory or a shaped refractory brick 11. Thermal expansion of the refractory partition wall 4 causes the entire partition wall to deform into a curved shape, so in order to prevent the partition wall from warping, it is necessary to provide a gap 5 to absorb thermal expansion. Partition walls collapsed during the outbreak,
This will cause the furnace to stop operating. The current construction method for seismic partition walls is as shown in Figure 1, in which regular refractory bricks are piled up so that the thickness of the lower partition wall is greater than that of the upper wall.
The only thing left to do is to use refractory mortar that has strong adhesion to firebricks.

脱落を防止する。Heat-resistant steel pipe PT! To prevent warping of the refractory partition wall caused by the difference between expansion and the thermal expansion of the refractory material, the length of the heat-resistant tube should be shorter than the molded refractory partition wall panel, and both ends should be hollow or ceramic. Pack lightly with fiber material. The length of the molded refractory partition wall panel is longer than the inside dimension of the heating furnace and shorter than the outside dimension of the furnace, and the length of the molded refractory partition wall panel is such that there is no space between the partition wall panel and the exterior plate of the furnace. Filled with ceramic fiber material to absorb thermal expansion and measure insulation effect. Fireproof partition wall panels can also be made by pasting ceramic fiber together with the refractory material, and the ceramic fiberboard can be welded to heat-resistant steel pipes and heat-resistant steel stud bolts, nuts, and bolts. Fix it. It is also possible to stack castable molded refractories with heat-resistant wire mesh or shaped refractory bricks between the molded fireproof partition wall panels.In that case, the refractories and panels are bonded with fireproof mortar and the castable molded fireproofing Prevent objects and shaped firebricks from falling off.
