Embodiment 1

[0028] A preparation method of a titanium pot with a composite aluminum bottom is realized through the following process:

[0029] (1) Put a sufficient amount of pure aluminum into a ceramic crucible, then put it into a muffle furnace and heat it to 700°C-850°C and keep it warm until the temperature of the molten aluminum is uniform;

[0030] (2) Clean the titanium pot with acetone, then fix the titanium pot 3 in the non-metallic fixture set 1, place the titanium pot 3 and the non-metallic fixture set 1 upside down on the insulating base 5, and evenly coat the bottom surface of the pot with Brush a layer of aluminum-based flux;

[0031] (3), feed a sufficient amount of argon gas into the front and back of the bottom of the pot for protection, and then energize the disc-shaped high-frequency induction heating coil 4 in the insulating base 5 to preheat the bottom of the pot;

[0032] (4), take out the ceramic crucible, scrape off the oxide film attached to the surface of the al...

Embodiment 2

[0035] Put a sufficient amount of pure aluminum into a ceramic crucible, place it in a muffle furnace and heat it to 700°C for 1 hour until the temperature of the molten aluminum is uniform. At the same time, clean the titanium pot with a diameter of 150mm with acetone and fix it in the non-metallic fixture sleeve, and then put it upside down and fix it on the insulating base. A sufficient amount of argon gas is injected into the reverse side to protect the bottom of the pot. The disc-shaped high-frequency induction coil placed in the insulating base is energized and heated, and the heating frequency is 20KHz, and the bottom of the titanium pot is preheated. Take out the crucible, scrape off the oxide film on the surface of the molten aluminum, and then pour the molten aluminum evenly on the bottom of the titanium pot to form a layer of molten aluminum with a thickness of 1mm on the bottom of the pot, and apply 20Hz mechanical vibration on the insulating base to promote the li...

Embodiment 3

[0037] Put a sufficient amount of pure aluminum into a ceramic crucible, place it in a muffle furnace and heat it to 750°C for 1 hour until the temperature of the molten aluminum is uniform. At the same time, clean the titanium pot with a diameter of 250mm with acetone and fix it in the non-metallic clamping sleeve, and then fix it upside down on the insulating base. Infuse a sufficient amount of argon to protect the bottom of the pot. The disc-shaped high-frequency induction coil placed in the insulating base is energized and heated with a heating frequency of 30KHz, and the bottom of the titanium pot is preheated. Take out the crucible, scrape off the oxide film on the surface of the aluminum liquid, and then pour the molten aluminum evenly on the bottom of the titanium pot to form a 1.5mm thick layer of aluminum liquid on the bottom of the pot, and apply 20Hz mechanical vibration on the insulating base to promote the aluminum liquid. Flow and spread on the bottom of the po...

Abstract

The invention discloses an aluminum bottom compounded titanium pot and a preparation method thereof. The method comprises the following steps of putting sufficient amount of pure aluminum into a crucible, heating the crucible together with the pure aluminum in a furnace, and keeping temperature till temperature of molten aluminum is homogenized; cleaning the titanium pot with acetone, fixing the titanium pot in a non-metallic fixture sleeve, invertedly fixing the titanium pot together with the fixture sleeve on an insulating base, and coating an aluminum-based brazing flux on the surface of the bottom of the pot; introducing argon to the front and back surfaces of the bottom of the pot for protection, electrifying a disc high-frequency induction heating coil in the insulating base, and preheating the bottom of the pot; taking the crucible out, scraping an oxidation film attached to the surface of the molten aluminum, and uniformly pouring the molten aluminum onto the bottom of the inverted titanium pot, so that a molten aluminum layer is formed on the bottom of the pot, and applying mechanical vibration to the insulating base; gradually reducing coil electrifying current till outage, and stop introducing argon for protection after the molten aluminum is solidified and cooled. The titanium pot prepared by the method has the advantages of high thermal conductivity, uniform heat transfer and the like, and avoids sticking, burning and the like when dishes are cooked.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a titanium pot with a composite aluminum bottom and a preparation method thereof. Background technique [0002] At present, the pots and utensils that people use in daily life are commonly made of iron pots, aluminum pots, stainless steel pots or other alloy pots. Generally speaking, iron pans are traditionally used by people. Experience and scientific research have proved that although they are beneficial to the human body or not harmful, they are heavy, easy to oxidize and rust, difficult to clean, and easy to damage. short. Aluminum pans are light in weight and fast in heat conduction, but have poor wear resistance. When encountering foods with strong acid and alkali, they will oxidize and release oxidized substances. Stainless steel cookware is one of the most acceptable products for consumers today. Its advantages lie in its resistance to acid and alkali corrosion, high t...
