Compared with the manufacturing method of existing three classes aluminum water chute prefabricated component, the manufacturing method of energy-saving aluminium water flow grooves prefabricated component is not
But it can ensure that preform material meets its working environment, and there is excellent energy-efficient performance, it is preferably to be applied to aluminum water stream
On mortise.
1. chemical stability and aluminum-resistant water reproducibility are very superior
Energy-saving aluminium water flow grooves prefabricated component is calcium hexaluminate and Calcium dialuminate, submember Al2O3 due to main constituents
With micro calcium aluminate, for Al2O3 and CaO resultant in 94.0wt% or more, impurity content is extremely low, and Al2O3 and CaO all cannot be by aluminium
Liquid reduction, so energy-saving aluminium water flow grooves prefabricated component stability at elevated temperature is fine, to resisting molten aluminum chemical erosion and also original
Congenital gene.
2. aluminum-resistant water scouring capability is stronger
Although energy-saving aluminium water flow grooves prefabricated component density is little, consistency is relatively low, the aggregate and matrix material of prefabricated component are formed
Expect that its real density is all very high, such as: CA6 real density 3.79g/cm3, CA2 real density 2.88g/cm3, Al2O3 real density 4.1g/
cm3。
3. volume stability and heat-resistant knocking stability are superior
Contain a large amount of calcium hexaluminate (CA6) and Calcium dialuminate (CA2), resultant in its object phase composition of energy-saving aluminium water flow grooves prefabricated component
In 60wt% or more；Though the calcium hexaluminate coefficient of expansion is larger, needle-shaped (rodlike) and sheet (or plate) shape is presented in it in material
State, this structure are conducive to absorb energy to failure, prevent crack extesion, improve the thermal shock resistance of material；Calcium dialuminate inherently has
There is low-down thermal expansion coefficient, also there was only 4.4 × 10 at 1400 DEG C-6℃-1；So constituting energy-saving aluminium water flow grooves prefabricated component
Composite material have outstanding high volume stability and heat-resistant knocking stability.
4. being not easy to be infiltrated by aluminum water
In general, antiwetting agent such as BaSO4 etc. need to be added to inhibit the infiltration of molten aluminum in aluminum water chute prefabricated component.And energy-saving aluminium water flow
Slot prefabricated component itself is just not easy to be infiltrated by aluminum water, this is mostly derived from the performance and microstructure of material itself.Calcium hexaluminate (CA6)
The reason of very low to molten aluminum wellability, and micro- stomata is also wellability low to molten aluminum between the crystal in its structure, hole diameter is small
It will be prevented from the infiltration of 1~2 micron of molten aluminum；There is a large amount of sealed porositys, air vent aperture in the structure of Ultralight CA6 aggregate
Size is in 1~5 micron of narrow range；Even if micro- air vent aperture size in material remains to protect through 1400 DEG C of high-temperature bakings
It is fixed to keep steady, then, in addition to CA6 itself has the characteristic for resisting aluminum water infiltration, the presence of the micro- stomata of diameter in the micron-scale be with
Based on calcium hexaluminate its micro- stomata of the energy-saving aluminium water flow grooves prefabricated component manufactured goods of raw material be exactly aluminum-resistant liquid soak it is another heavy
Want reason.

With prefabricated component, (vitreous silica fireproofing prefabricated member, Bauxite-based refractories prefabricated component and Sai Long combine molten major class aluminum water chute
Fused silica fireproofing prefabricated member) it is minimum compared to density, that is to say, that and energy-saving aluminium water flow grooves prefabricated component is during the work time not
Need to absorb too many heat, to reduce the accumulation of heat loss of prefabricated component, being reached for aluminum i ndustry enterprise reduces the purpose of energy consumption；
2) the two of energy-saving aluminium water flow grooves prefabricated component energy conservation reason: high porosity
Ultralight calcium hexaluminate aggregate apparent porosity 70~75% in energy-saving aluminium water flow grooves prefabricated component ingredient, Calcium dialuminate
(CA2) energy-saving aluminium water flow grooves of/calcium hexaluminate (CA6) the complex phase lightweight clinker apparent porosity 45~50%, by high temperature firing
Prefabricated component is in addition to having a certain amount of micro- stomata of opening, and internal there are also a large amount of sealed porosity, these stomatas hinder the biography of heat
It passs, reduces the thermal loss in molten aluminum conveying, can reduce enterprise energy consumption.
3) the two of energy-saving aluminium water flow grooves prefabricated component energy conservation reason: thermal conductivity is low
Thermal conductivity is to indicate the physical parameter of material thermal conductivity ability, and thermal conductivity is higher, and material is easier to heat to pass to out
It goes, will result in heat loss, every kind of material has the thermal conductivity of oneself.
The aggregate of energy-saving aluminium water flow grooves prefabricated component by Calcium dialuminate (CA2)/calcium hexaluminate (CA6) complex phase lightweight clinker and
The composition such as Ultralight calcium hexaluminate is formed since the en plaque structure and material internal crystal of calcium hexaluminate crystal are staggeredly grown
Honeycomb structure, overall structure similar to ceramic fibre structure, so have lower thermal conductivity, but also energy-saving aluminium
The relatively other existing prefabricated component composite materials of the thermal conductivity of water flow grooves prefabricated component are much lower, and the capacity of heat transmission or heat transfer rate are wanted
It is much lower, therefore the heat by prefabricated component conductive heat loss in molten aluminum conveying is with regard to lower, it will be able to thermal energy is made full use of, is dropped
Low enterprise energy consumption.
