Abstract
The invention discloses a heat preservation structure of a high temperature furnace. A closed box type or case type container is made of a high-temperature resistant metal material, such as tungsten and molybdenum; zirconium oxide fibers, aluminum oxide fibers, aluminum silicate fibers or zirconium oxide hollow balls are filled in the container; the whole heat preservation body is formed by dispersed heat preservation materials such as the zirconium oxide hollow balls; the shape of the heat preservation body is designed according to a demand; and the heat preservation body can be used independently or jointly. By the heat preservation structure, a good heat preservation effect of loose fiber cottons or the hollow balls can be guaranteed; the materials have certain rigid appearances and can be used in different regions of the high temperature furnace; and the technology in the invention is suitable for heat preservation inside various high temperature furnaces.
Description
Affiliated technical field
The present invention is applicable to various high temperature furnace insulations or thermal protection system.
Background technology
The existing high temperature furnace insulation material larger refractory brick of various rigidity that adopt more, the general thermal conductivity factor of refractory brick is larger, and heat insulation effect is good not; High temperature furnace with vacuum condition also can adopt the multilayer insulation screen to carry out thermal protection, but this mode is not good enough for the general effect of middle low-temperature zone thermal protection.
Summary of the invention
Tungsten, molybdenum, stainless steel and other metal materials are prefabricated into boxlike or box-type container with processing modes such as welding, riveted joint, punching presses, the high-temperature fibre that the filling thermal conductivity factor is extremely low in the container again, particle, hollow ball loose fill type insulant form a complete thermal insulator, this thermal insulator takes full advantage of the good heat-insulating property of loose fill type insulant, and make it have required profile, exempt simultaneously discrete material for the harmful effect of furnace inner environment.
This thermal insulator can be used separately, also can use by a plurality of blocks.
The thermal insulator shell can be the metal or alloy such as tungsten, molybdenum, stainless steel, designs depending on serviceability temperature.
The inner filling material can be the ready-made fiber such as alumina silicate, aluminium oxide, zirconia, particle, tiny hollow ball etc. loose shape.

The specific embodiment
The present invention is further illustrated with this embodiment below in conjunction with accompanying drawing:
According to box (6) and cover plate (5), stove cylinder box (4) and cover plate (3) thereof, bell box (2) and cover plate (1) thereof at the bottom of the design size difference finishing stove.Then in furnace bottom box (6), fill diameter 2-3MM alumina hollow ball, fill aluminosilicate fiber cotton in stove cylinder box (4) and the bell box (2), respectively separately cover plate box (5), (3), (1) is corresponding with it fixes.Again furnace bottom (9), stove cylinder (8), bell (7) incubation chamber are put into successively prefabricated furnace shell and can be finished whole stove heat-insulation system processing.
Claims (5)
1. high temperature furnace insulation construction, it is characterized in that making closed boxlike or box-type container by metal materials such as tungsten, molybdenums, the dispersion materials such as inner filling high-temperature fibre cotton or high-temperature resistant hollow spheres form the thermal insulator that certain rigid shape has again good heat-insulating property simultaneously.
2. boxlike according to claim 1 or box-type container, its internal cavities shape can be the arbitrary shapes such as cuboid, cylindrical, annular, and the spacing or supporting bracket of discrete material can optionally be set in the cavity.
3. boxlike according to claim 1 or box-type container are made by various metal forming modes such as welding, riveted joint, punching presses by metal or alloy such as tungsten, molybdenum, stainless steels.
