Abstract
A smelting furnace for gravity casting technology comprises a melting chamber, a hardening and tempering chamber and a utilization chamber, wherein two rotating degassing pipes are arranged in the hardening and tempering chamber; and the parts of the degassing pipes in contact with aluminum liquid are made of graphite material. In the utility model, because one degassing pipe is additionally, and the parts in contact with the aluminum liquid are made of fireproof material, the degassing effect is better.
Description
Technical field:
The utility model relates to a kind of Casting Equipment, particularly a kind of smelting furnace that is used for gravity foundry technology.
Background technology:
The smelting furnace that is used for aluminium alloy smelting in the prior art is varied, wherein a kind of smelting furnace that is used for gravity foundry technology, include melting chamber, modified chamber and use the chamber, be provided with the first aluminium liquid connected entrance between melting chamber and the modified chamber, be provided with the second aluminium liquid connected entrance between modified chamber and the use chamber, during melting, the aluminium alloy melt drops into melting chamber and is smelted into aluminium liquid, aluminium liquid flows into by the first aluminium liquid connected entrance that go bad in modified chamber, thinning processing, and uses the chamber standby after modified aluminium liquid enters by the second aluminium liquid connected entrance.The shortcoming of this structure is:
1, enters modified indoor aluminium liquid and generally all contain hydrogen, because hydrogen is a kind of pernicious gas, bring harm can for the processing characteristics and the quality of aluminium product, therefore need to get rid of, and only be to eradicate tracheae by one to finish this work in the prior art, can not reach good degassing effect, await improving.
2, aluminium liquid can not obtain good purified treatment in the process of circulation, causes final liquation purity not high, is unfavorable for follow-up product casting.
The utility model content:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of improved smelting furnace is provided, and it not only can improve the exhaust effect of modified chamber, but also can better carry out the deslagging purified treatment to aluminum solutions.
According to a kind of smelting furnace that is used for gravity foundry technology that the utility model provides, comprise melting chamber, modified chamber and use the chamber that the described modified indoor two rotary gas removing pipe that are provided with are that graphite material is made with aluminium liquid contact portion in the described gas removing pipe.
In addition, the utility model also has following attached technical characterictic:
Be provided with the first aluminium liquid connected entrance between described melting chamber and the modified chamber, be provided with the second aluminium liquid connected entrance between described modified chamber and the use chamber.
Described first, second aluminium liquid connected entrance place is provided with the screen pack of being made by refractory material respectively.
Described first, second aluminium liquid connected entrance place is provided with the screen pack of being made by foamed ceramics respectively.
Smelting furnace according to the utility model provides has following advantage with respect to prior art:
At first, the utility model is at the modified indoor two elimination tracheaes that are provided with, and for one of the prior art, its degassing effect is better.
Secondly, the utility model has increased the foam ceramic filter net respectively at the first aluminium liquid connected entrance and the second aluminium liquid connected entrance place, therefore, the aluminium liquid that flows out melting chamber and the modified chamber of outflow can carry out a slag removal and purification respectively to be handled, use the liquation purity of chamber to be improved thereby make to flow into, ensured the casting quality that product is follow-up.
Description of drawings:
Introduce the utility model in detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a main TV structure schematic diagram of the present utility model;
Fig. 2 is the sectional structure schematic diagram of A-A direction among Fig. 1.
The specific embodiment:
See figures.1.and.2, the smelting furnace that is used for gravity foundry technology that provides according to the utility model, comprise melting chamber 1, modified chamber 2 and use chamber 3, be provided with two rotary gas removing pipe 21 in the modified chamber 2, thereby exhaust effect is good, be that graphite material is made with aluminium liquid contact portion in the described gas removing pipe 21, to reach high temperature resistant and fire-resistant purpose, other parts can be formed from steel.Wherein, be provided with the first aluminium liquid connected entrance 4 between melting chamber 1 and the modified chamber 2, be provided with the second aluminium liquid connected entrance 5 between modified chamber 2 and the use chamber 3, described first, second aluminium liquid connected entrance 4,5 places are provided with the screen pack of being made by refractory material 6,7 respectively, for example, make by foamed ceramics.During use, the aluminium liquid in the melting chamber 1 enters modified chamber 2 after removing the gred through filter screen 6, enters after the aluminium liquid in the modified chamber 2 remove the gred once more through filter screens 7 and uses chamber 3 standby.
