Abstract
It the utility model is related to a kind of compound refractory brick, including heavy structure of refractory and lightweight refracrory structure；The lightweight refracrory structure is three light-weight refractory rods, and the light-weight refractory rod intersects to form three-legged structure, and the both ends of each light-weight refractory rod are located above and below adjacent light-weight refractory rod respectively；Lightweight refracrory encapsulated by structures in inside and is formed bricked by the heavy structure of refractory；Two end surfaces of the light-weight refractory rod flush with the surface of heavy structure of refractory.The utility model inserts the club shaped structure of lightweight refracrory support in traditional heavy refractory brick, can reduce its thermal conductivity factor and weight on the premise of refractory brick intensity is ensured.
Description
Technical field
It the utility model is related to technical field of refractory materials, more particularly to a kind of compound refractory brick.
Background technology
Refractory brick abbreviation firebrick.The refractory material being fired into refractory clay or other refractory raw materials.It is faint yellow or with brown
Color.It is mainly used in building smelting furnace, is resistant to 1,580 DEG C -1,770 DEG C of high temperature.Also it is firebrick.With definite shape and size
Refractory material.By process of preparing come divide can be divided into be fired into bricks, unburned brick, fused cast refractories（Molten-cast brick）, refratory insulating brick；Press
Shape and size can be divided into standard size brick, common brick, specific bricks etc..It can be used as building kiln and the high temperature of various Thermal Equipments
Construction material and structural material, and various physicochemical changes and mechanism are amenable at high temperature.
In general, refractory material more retells that bright material density is high, intensity is big, service life length, but corresponding,
The thermal conductivity factor of heavy refractory material is also larger, and heat waste can not reduce.
Utility model content
In order to solve the above-mentioned technical problem, there is provided one kind can guarantee that high intensity, have the fire resisting compared with low thermal conductivity again
Brick, the utility model provide following technical scheme：
A kind of compound refractory brick, including heavy structure of refractory and lightweight refracrory structure；The light-weight refractory
Material structure is three light-weight refractory rods, and the light-weight refractory rod intersects to form three-legged structure, and the two of each light-weight refractory rod
End is respectively above and below adjacent light-weight refractory rod；The heavy structure of refractory is by lightweight refracrory structure bag
It is wrapped in inside and forms bricked；Two end surfaces of the light-weight refractory rod flush with the surface of heavy structure of refractory.Lightweight
The addition of resistance to lighted torch can mitigate the weight of refractory brick, reduce thermal conductivity factor, meanwhile, light-weight refractory rod intersects to form three-legged structure
There is higher structural stability and intensity compared to resistance to lighted torch is inserted directly into.
Further, the lightweight refracrory structural volume and the volume ratio of heavy structure of refractory are 1:1.5-2
In principle, lightweight refracrory structural volume is bigger, thermal conductivity factor reduction is more obvious, if but lightweight refracrory structural volume
It is excessive, mean that the diameter of resistance to lighted torch is bigger, and space is limited in refractory brick, can not meet that the resistance to lighted torch of major diameter is mutually handed over
The demand of fork.
Further, the heavy structure of refractory surface is further opened with insulation hole, and the insulation hole is not resistance to lightweight
Fiery material structure contact.
Further, the insulation hole is gradually reduced from table to inner aperture.
The beneficial effects of the utility model are：Fire resisting can be mitigated on the premise of ensureing refractory brick intensity with durability
Brick body product, reduce its thermal conductivity factor.
Brief description of the drawings
Fig. 1, primary structure schematic diagram of the present utility model.
In figure：1st, heavy structure of refractory, 2, lightweight refracrory structure, 3, insulation hole.
Embodiment
A kind of compound refractory brick as shown in Figure 1, including heavy structure of refractory 1 and lightweight refracrory structure 2；
The lightweight refracrory structure 2 is three light-weight refractory rods, and the light-weight refractory rod intersects to form three-legged structure, and each light
The both ends of the resistance to lighted torch of matter are respectively above and below adjacent light-weight refractory rod；The heavy structure of refractory 1 is by lightweight
Structure of refractory 2 is wrapped in inside and forms bricked；Two end surfaces of the light-weight refractory rod and heavy structure of refractory
1 surface flushes.The addition of light-weight refractory rod can mitigate the weight of refractory brick, reduce thermal conductivity factor, meanwhile, light-weight refractory rod
Intersecting to form three-legged structure has higher structural stability and intensity compared to being inserted directly into resistance to lighted torch.
The volume of lightweight refracrory structure 2 and the volume ratio of heavy structure of refractory 1 are 1:2, in principle, gently
The volume of fire resistant materials structure 2 is bigger, the reduction of thermal conductivity factor is more obvious, but if the volume of lightweight refracrory structure 2 is excessive
Mean that the diameter of resistance to lighted torch is bigger, and space is limited in refractory brick, can not meet the cross one another need of resistance to lighted torch of major diameter
Ask.The surface of heavy structure of refractory 1 is further opened with insulation hole 3, the insulation hole 3 not with lightweight refracrory structure 2
Contact.The insulation hole 3 is gradually reduced from table to inner aperture.
Using above-mentioned foundation the utility model desirable embodiment as enlightenment, pass through above-mentioned description, relevant staff
Various changes and amendments can be carried out in the range of without departing from this item utility model technological thought completely.This item is practical
New technical scope is not limited to the content on specification, it is necessary to determines that its is technical according to right
Scope.
