Abstract
The utility model discloses thermal shock resistance sintering refractory slabs resistant to high temperature by force, include base, middle layer and surface layer, the base is prepared with calcined alumina material, middle layer is prepared with carbofrax material, and surface layer is prepared with durable high temperature inert material, and the refractory slab both ends are branch fastener, adhesive slot is provided on branch fastener, refractory slab midfeather is provided in grid hole that is parallel or being interspersed, and base's bottom interval is provided with arcuate slots, is arranged in the surface layer fluted.The utility model is conducive to the transmitting of thermal energy, improve sintering efficiency, the energy is saved, second is that being conducive to balance and reduce the structural stress that multiple material is shunk in high temperature sintering, refractory slab is made to combine stronger be unlikely to deform, it is not only compact-sized, internal stress is small and disperses, high temperature resistant, and thermal shock resistance is strong and this refractory slab is conducive to the sintering of product, can improve sintering efficiency, energy consumption is reduced, the quality of product is improved.
Description
Technical field
The utility model relates to kiln technical field, more particularly to a kind of for being used to support or holding up sintering production in kiln
The attachment of product.
Background technique
It, greatly will will be by with a kind of supporter in shuttle-type, tunnel or the pusher furnace that magnetic, electrode and ceramic are fired
The product of sintering is held up, in order to product sintering.This supporter is in stove industry general term refractory slab.Since refractory slab need to be when long
Between in the high temperature and support product, therefore refractory slab not only wants high temperature resistant in high-temperature sintering process, there is preferable mechanical strength,
And to have preferable heat-resistant knocking stability, otherwise refractory slab is easy to happen cracking, can be broken when serious, leads to system in stove
Toppling Deformation or damage can occur in sintering for product, or even product is caused to scrap.The refractory slab used currently used for kiln there is also
Following problems: first is that refractory slab material is mainly alumina ceramic plate, carborundum plate ceramic wafer and fire clay plate, these materials
Surface is oxidizable at high temperature for refractory slab, it may occur that cracking or fracture；Second is that refractory slab structure is less reasonable, the refractory slab in high temperature sintering
Each partial contraction sex differernce is larger, and refractory slab can generate biggish stress concentration, and refractory slab is caused to crack, and shortens making for refractory slab
With the service life, production cost is improved.
Utility model content
Aiming at the problem that above-mentioned refractory slab in the prior art is in the presence of high temperature sintering, the utility model provides one kind not
The laminar only compact-sized, internal stress is small and dispersion, high temperature resistant, and thermal shock resistance are strong is sintered refractory slab.
The technical problems to be solved in the utility model the technical solution adopted is that: thermal shock resistance sintering resistant to high temperature by force
Refractory slab is prepared including integrally formed base, middle layer and surface layer, the base from bottom to top with calcined alumina material,
Middle layer is prepared with carbofrax material, and surface layer is prepared with durable high temperature inert material, and the refractory slab both ends are support
Head, adhesive slot is provided on branch fastener, and refractory slab midfeather is provided in grid hole that is parallel or being interspersed, the substrate base
Portion is arranged at intervals with arcuate slots, is arranged on the panel fluted.
The utility model is first is that due to combining manufactured refractory slab using multiple material, and the surface layer with product into contact is using durable
High temperature inert material is made, and prevents product mutually be bonded with surface layer, such as Zirconium oxide fibre, alumina fibre or alumina silicate fibre, and
For middle layer using indeformable silicon carbide layer at high temperature, base is high using intensity, not oxidizable calcined alumina material system
At can both make refractory slab that there is high intensity, high temperature resistant, and thermal shock resistance is strong in this way, simultaneously because having in product structure upper layer
Fluted, centre has grid hole, and base has arcuate slots, second is that mitigating canopy under with enough intensity and thermal shock resistance
The weight of plate, is conducive to the transmitting of thermal energy, improves sintering efficiency, saves the energy, third is that be conducive in high temperature sintering balance and
The structural stress that multiple material is shunk is reduced, refractory slab is made to be unlikely to deform and crack in conjunction with stronger.
The utility model is not only compact-sized, internal stress is small and disperses, high temperature resistant, and thermal shock resistance is strong, this refractory slab
Be conducive to the sintering of product, sintering efficiency can be improved, energy consumption is reduced, improve the quality of sintered article.

Specific embodiment
In order to enable those skilled in the art to better understand the technical solutions of the present invention, it combines and has below according to attached drawing
The utility model is described in further detail in body embodiment.
In fig. 1, fig. 2 and fig. 3, a kind of thermal shock resistance sintering refractory slab resistant to high temperature by force, it includes being integrally formed from bottom to top
Base 1, middle layer 5 and surface layer 3, the base is prepared with calcined alumina material, middle layer carbofrax material system
Standby to form, surface layer is prepared with durable high temperature inert material, in a model by three kinds of material layer layering fillings, is made by compacting
It is bonded into one, then is fired into refractory slab entirety by high temperature, and the refractory slab both ends are branch fastener 7, is provided on branch fastener viscous
Close slot 8, refractory slab be fixed on furnace wall or furnace stay using branch fastener and adhesive slot, refractory slab midfeather be provided in parallel or
The grid hole 6 being interspersed, it is arc-shaped arcuate slots 2, arcuate slots front and back two that the base plate bottom, which is arranged at intervals with cross sections,
End seal is closed, and arcuate slots maximum height (depth) is the half of base's height, is arranged fluted 4 on the panel, groove
Depth (height) is less than the half of surface thickness, and the left and right ends of groove are connected with branch fastener monoblock type.
