(3), pass into enough argon gas at the bottom of a pan positive and negative and protect, by the plate-like high-frequency induction heating coil electricity in insulator foot, preheating is carried out in the bottom of a pan afterwards;
(4), take out ceramic crucible, scrape off the oxide-film of aluminium liquid surface attachment, it is cast on the inverted titanium pot the bottom of a pan equably, make to form certain thickness aluminium liquid layer on the bottom of a pan, on insulator foot, apply mechanical oscillation and promote aluminium liquid flowing on the bottom of a pan;
(5) decay, gradually coil electricity electric current until power-off stops logical argon shield after aluminium liquid solidifies and is cooling.
The present invention also has following technical characterictic:
1, described fine aluminium liquid or be LF21 alumal liquid.
2, described aluminium base brazing flux is QJ201, or is Nocolok brazing flux.
3, the high-frequency induction heating coil heats frequency of described employing is: 20KHz～100KHz.
4, described mechanical oscillation frequency range is 20Hz-30Hz, and mechanical oscillation are used for the flowing and sprawling on the bottom of a pan into aluminium liquid.
5, the titanium pot at the bottom of a kind of clad aluminum making by method as above.
Invention effect and advantage:
1. utilize titanium pan prepared by this method to have that thermal conductivity is good, the advantage such as even of conducting heat, the problem such as be not prone to sticky pot while cooking vegetable, be charred.
2. the mode deposited certain thickness aluminium lamination on the titanium the bottom of a pan that adopts cast aluminum liquid, technique is simple.
3. under the condition of radio-frequency preheating and argon shield, between the titanium pot the bottom of a pan and aluminium liquid, realize metallurgical binding, bond strength is high, composite base difficult drop-off or cracking.
4. utilize the mechanical oscillation on electromagnetic force and the insulator foot that high-frequency induction produces to promote aluminium liquid flowing on the bottom of a pan, aluminium liquid is sprawled evenly.
