Obtained electric hot tray.
Background technology
Aluminium alloy is a kind of non-ferrous metal structural material being most widely used in industry, have density is low, intensity than it is high,
The advantages of plasticity is good, good conductivity, good corrosion stability, it is adapted to be processed into various section bars.Just because of with thermal conductivity it is high the characteristics of,
In heating, there is huge use value in terms of cooling, thus applied in many industries to heater, cooler uses
Prepared by aluminium alloy, such as the electric hot tray of the heater in semicon industry, automobile radiators, computer fan and various uses
Deng.
With the development need of all trades and professions, requirement to alumiaum article also more and more higher.Such as household electrical appliances, the aluminum of chemical industry
Electric hot tray, it is many to its heating uniformity, stability, the rate of heat addition, security etc. to require more and more higher.Above-mentioned electric hot tray
Also referred to as heating dish, in the prior art aluminum electric hot tray use split-type structural more, be to separate heating wire and its fitting recess
It is machined out, is then assembled, such processing mode has processing generation fit-up gap and easily causes heat conduction barrier film, processing

Embodiment
With reference to embodiment, the present invention will be described in detail.
Block cast formula aluminium alloy in the present embodiment carries out proportioning manufacture according to component in following table and weight/mass percentage composition（Form
Middle data are the weight/mass percentage composition of corresponding component）.Surplus is Al in following table formula, is also included in aluminium alloy inevitably miscellaneous
Matter, wherein Zn≤0.05wt%, Sn≤0.005wt%, Pb≤0.01wt%, Cr≤0.01wt%, Cd≤0.003wt%, Mo≤
0.001wt%。
Zn, Sn, Pb, Cr, Cd, Mo are the impurity most often occurred in aluminium alloy manufacturing process in the present embodiment, need to strictly be controlled
Impurity content processed, impurity content is controlled to account for less than the 0.3% of alloy gross mass in the present embodiment.It is in practice, it has been found that once miscellaneous
Matter content exceedes the mass percent, then in electric hot tray casting process, aluminium alloy easily produces attachment on steel galvanic couple surface,
Gap is caused, influences the use of electric hot tray.To find out its cause, impurity content is too high easily to cause molten aluminium alloy in fusion process
Entropy is too high, so as to influence its shaping and crystallization.
Electric hot tray is prepared using the process of block cast formula according to the proportioning of above-mentioned aluminium alloy, casting technique step is main
For：
S01：Component formula according to block cast formula aluminium alloy puts into all raw materials into smelting furnace；
S02：Sufficient electromagnetic agitation is carried out after raw material is completely melt, is skimmed, melting holding temperature is 750-780 DEG C, this reality
It is optimal, smelting time 6h to apply in example with 755-760 DEG C；The heating rate of fusion process is 5 DEG C/min；
S03：Treat to carry out liquation cast after aluminium alloy smelting, pouring temperature is preferably 725-727 DEG C in the present embodiment, waits to cast
Part cools down, electric hot tray needed for acquisition.
Aluminium alloy smelting temperature in the present embodiment is slightly above aluminium alloy smelting temperature of the prior art, traces it to its cause
Alloying element species is more, it is necessary to which higher temperature and more heat energy can make each element phase in aluminium alloy in the present invention
Mutually fusion forms homogeneous phase body, and high smelting temperature is also beneficial to the crystallisation by cooling of follow-up aluminium alloy.It is adapted with smelting temperature
Be cast temperature, the electric hot tray moulding process that uses is for casting process in the present invention, because aluminium alloy thermal capacitance is small, cools down
Block, therefore pouring temperature is also and its important, temperature is too high then oxidizable, and temperature is low, is also easy to produce cold shut, misrun.In the present invention
Middle aluminium alloy density, melting purity, the uniformity, smelting temperature and pouring temperature complement each other, once wherein a certain parameter occurs
Change, can have an impact to the forming preparation process and quality of finished of electric hot tray.
During cast, the cross-sectional area between sprue, cross gate, ingate three also needs accurately to be controlled
System, if the flux between three running channels does not use suitable proportioning, can easily cause molten aluminium alloy misrun in casting process,
The defects of sprue can not form full state, easily parcel gas produces stomata.Ratio and casting between three running channel sections
Electric hot tray size is relevant, during actual casting, when the electric hot tray quality of casting is less than 3kg, a diameter of 12- of sprue
12.5mm；The ratio between cross-sectional area between sprue, cross gate, ingate three is 1:（1.80-1.95）：（4.05-4.2）.
When the electric hot tray quality of casting is less than 10kg, a diameter of 24.0-26.0mm of sprue more than 3kg；Sprue, cross gate, interior pour
The ratio between cross-sectional area between road three is 1:（1.70-1.75）：（3.55-4.0）.When the electric hot tray quality of casting is more than
10kg, a diameter of 28-35mm of sprue；The ratio between cross-sectional area between sprue, cross gate, ingate three is 1:（1.70-
1.75）：（4.2-4.5）.
In the present embodiment, to be easy to compare, the aluminium alloy in embodiment is poured into 2.55kg, 5kg, 12kg respectively
Electric hot tray.When the electric hot tray quality of casting is 2.55kg, a diameter of 12mm of sprue, sprue, cross gate, ingate three it
Between the ratio between cross-sectional area be 1:1.92：4.1.When the electric hot tray quality of casting is 5kg, a diameter of 25mm of sprue, sprue,
The ratio between cross-sectional area between cross gate, ingate three is 1:1.73：3.64.When the electric hot tray quality of casting is 12kg, directly
The ratio between a diameter of 30mm of running channel, the cross-sectional area between sprue, cross gate, ingate three is 1:1.75：4.5.
Compare with the embodiment in the present invention, utilized and embodiment identical block cast using ZL106, ZL114A aluminium alloy
Same 2.55kg, 5kg, 12kg electric hot tray is made in technique, is designated as comparative example 1, comparative example 2 respectively, below for embodiment with it is right
Comparative result between ratio.
As can be seen from the comparison result, the block cast formula aluminium alloy electric hot plate uniformity and mouldability in the embodiment of the present invention
Get well, especially embodiment 11-18, be more uniformly distributed on appearance clean and tidy.And conventional ZL106, ZL114A aluminium alloy is then difficult to
Carry out the preparation of block cast formula electric hot tray.Block cast formula aluminum alloy materials mouldability in the present embodiment is good, good heat conduction effect, in its casting
Oxide skin and impurity are not likely to produce during making, can with steelwork is extraordinary fits together, after the completion of electric hot tray casting
Gap will not be produced, the defects of so as to overcome in the prior art.
It is last it should be noted that above example is only illustrating the technical scheme of the embodiment of the present invention rather than it is entered
Row limitation, although the embodiment of the present invention is described in detail with reference to preferred embodiment, one of ordinary skill in the art
It should be understood that can still be modified to the technical scheme of the embodiment of the present invention or equivalent substitution, and these modifications or wait
The scope of amended technical scheme disengaging technical scheme of the embodiment of the present invention can not also be made with replacement.
