Abstract
The utility model discloses a hollow refractory slab for a high-temperature kiln. The cross section of the refractory slab (1) is in a hollow structure (2), and the refractory slab (1) is a silicon nitride and silicon carbide combined or self-combining silicon carbide refractory slab. Since the cross section of the refractory slab is in the hollow structure, the bearing performance is reasonable, and the weight is lighter. By adopting the structure, an ultra thin refractory slab with large size and heavy load can be manufactured, the problem that a product of a large workpiece can not be loaded due to kiln furniture can be solved, and thus the loading rate and the yield of the kiln are further improved. As a beam and slab structure is adopted when the kiln is in loading, the number of supporting uprights is fewer; at the edge of the kiln vehicle and in the middle of the vehicle surface, the encastage difficulty can not be caused due to the influence of the supporting uprights; thus, the randomness is strong, the kiln full rate is high, the energy consumption can be greatly reduced, and the firing cost can be lowered.
Description
Technical field
The utility model relates to high temperature kiln and use the refractory slab field, particularly silicon nitride combined silicon carbide composite material hollow refractory slab and from the hollow refractory slab of based on silicon carbide.
Background technology
At present, the silicon nitride combined silicon carbide that on high temperature kiln, uses and from the based on silicon carbide refractory slab, they play a part to carry and are heated workpiece and in kiln, fire, and are that kiln is fired the indispensable high temperature resistant carrying tool of workpiece.Owing to existing silicon nitride combined silicon carbide, from the based on silicon carbide refractory slab all is solid flat board; The area of refractory slab can not be made too big; Loading of kiln needs many shore supports, causes the big workpiece product loading difficulty of being fired big, and the full rate of kiln is low; Therefore fire the significant wastage that causes the energy in the product process at kiln, it is higher to fire cost.
The utility model content
The purpose of the utility model produces thus, proposes a kind of high temperature kiln and uses hollow refractory slab, and solution has the refractory slab Heavy Weight now, area is little, pillar is many, the workpiece goods further improve the charging ratio of kiln, yield rate because of the problem that kiln furnitures can't load greatly.Avoided the waste of the energy.
The utility model realizes that the technical scheme that above-mentioned purpose adopts is: a kind of high temperature kiln is used refractory slab, and the cross section of this refractory slab is the interval hollow-core construction.
The described high temperature kiln of the utility model uses refractory slab as the silicon nitride combined silicon carbide refractory slab or from the based on silicon carbide refractory slab.
The utility model is owing to the cross section with refractory slab is designed to hollow-core construction at interval, and it carries, and stress performance is reasonable, weight is lighter.Adopt this structure can manufacture big specification, the ultra-thin refractory slab of heavy load, can solve big workpiece goods, the charging ratio of kiln, yield rate are further improved because of kiln furnitures can't load problem.When kiln loads, adopt contignation, support post is few, and on the kiln car limit, can be in the middle of the car face because of the column influence does not cause the loading of kiln difficulty, randomness is strong, and the full rate of kiln is high, can reduce energy resource consumption significantly, practices thrift and fires cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, refractory slab, 2, hollow-core construction at interval.
The specific embodiment
In conjunction with accompanying drawing, the embodiment that provides the utility model is following:
As shown in Figure 1: the described high temperature kiln of present embodiment is used refractory slab, is specially silicon nitride combined silicon carbide composite material hollow refractory slab or from the hollow refractory slab of based on silicon carbide.The cross section of said refractory slab 1 is an interval hollow-core construction 2.
Claims (2)
1. a high temperature kiln is used refractory slab, comprises refractory slab (1), it is characterized in that: described refractory slab (1) cross section is interval hollow-core construction (2).
2. high temperature kiln according to claim 1 is used refractory slab,, it is characterized in that: described refractory slab (1) is for the silicon nitride combined silicon carbide refractory slab or from the based on silicon carbide refractory slab.
