Description
Technical field
The present invention relates 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.Divided by process of preparing 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, special shaped brick 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 is long, but corresponding,
The thermal conductivity factor of heavy refractory material is also larger, and heat waste can not be reduced.
The content of the invention
In order to solve the above-mentioned technical problem high intensity is can guarantee that there is provided one kind, there is the fire resisting compared with low thermal conductivity again
Brick, the present invention provides following technical scheme:
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 two ends point of each light-weight refractory rod
Wei Yu not be above and below adjacent light-weight refractory rod;The heavy structure of refractory by lightweight refracrory encapsulated by structures in
Inside simultaneously forms bricked;Two end surfaces of the light-weight refractory rod are flushed with the surface of heavy structure of refractory.Light-weight refractory
The addition of rod can mitigate the weight of refractory brick, reduction thermal conductivity factor, meanwhile, light-weight refractory rod intersects to form three-legged structure and compared
Resistance to lighted torch is inserted directly into higher structural stability and intensity.
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, it is impossible to the resistance to lighted torch for meeting 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.
Further, the heavy structure of refractory is made up of the following component in terms of mass fraction:Fused white corundum
30-40 parts, 20-35 parts of portland cement, 1-2.5 parts of zinc, 3-6 parts of nickel cobalt (alloy), 5-8 parts of phenolic resin, 2-6 parts of silica flour, oxygen
Change 1-3 parts of magnesium;The lightweight refracrory structure is made up of the following component in terms of mass fraction:10-15 parts of fused white corundum,
30-40 parts of phenolic resin, 10-20 parts of carborundum, 10-15 parts of andalusite, 3-6 parts of aluminum oxide, 1-3 parts of zirconium oxide.The present invention is adopted
The addition of phenolic resin composition in heavy refractory material allows material to be kneaded at a lower temperature, into
Type, plasticity is strong, and the addition of zinc and nickel cobalt (alloy) composition can then improve the hardness of heavy refractory material, enables in particular to improve it
High temperature fracture intensity level;Larger amount of phenolic resin has been used in the lightweight refracrory that the present invention is used, equally can compared with
It is molded at low temperature, meanwhile, the addition of aluminum oxide and zirconium oxide can improve the fusing point and hardness of material.
The beneficial effects of the present invention are:Refractory brick body can be mitigated on the premise of ensureing refractory brick intensity with durability
Accumulate, reduce its thermal conductivity factor;And two kinds of refractory material moulding process of the present invention are simple, manufacturing cost is low.
Brief description of the drawings
Fig. 1, the present invention primary structure schematic diagram.
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 two ends of the resistance to lighted torch of matter are located above and below adjacent light-weight refractory rod respectively;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 is flushed.The addition of light-weight refractory rod can mitigate the weight of refractory brick, reduction thermal conductivity factor, meanwhile, light-weight refractory rod
Intersect to form three-legged structure has higher structural stability and intensity compared to resistance to lighted torch is inserted directly into.Weight described in the present embodiment
Fire resistant materials structure is made up of the following component in terms of mass fraction:35 parts of fused white corundum, 25 parts of portland cement, zinc
1.5 parts, 5 parts of nickel cobalt (alloy), 6 parts of phenolic resin, 4 parts of silica flour, 2 parts of magnesia;The lightweight refracrory structure is by with quality
