Abstract
The utility model aims to disclose an online degassing device for casting, which comprises a hood. A plurality of graphite rotors are arranged inside the hood and are hollow, driving motors used for driving the graphite rotors to rotate are disposed on the top of the hood, and blowing devices are connected to top ends of the graphite rotors. The motors drive the graphite rotors to rotate, the blowing devices adjust gas pressure and blow gas into a melt, hydrogen content in the melt is removed, slag removal effect can also be realized, the quality of cast billets is improved, and the online degassing device is simple in structure, is quite practical and realizes purposes.
Description
Technical field
The utility model relates to a kind of air-removal equipment, the online air-removal equipment of particularly a kind of casting.
Background technology
Aluminium alloy is in fusion process, usually touch furnace gas such as hydrogen, oxygen, water vapour, carbonic acid gas, sulfurous gas etc., these gases are mainly by producing after the fuel combustion, the gas of gas molecule state generally can not be dissolved in the alloy liquid, have only when gas molecule is decomposed into active atomic, just might dissolve.Composition of fumes is decided by fuel type and air capacity.Ordinary coke crucible oven, composition of fumes are mainly carbonic acid gas, sulfurous gas and nitrogen; Coal gas, heavy oil crucible oven are mainly water vapour, nitrogen; And concerning the electrosmelting that present most of melting producer uses, composition of fumes mainly is a hydrogen.Therefore, when adopting different smelting furnace meltings, the inspiratory capacity of aluminium alloy is different with the degree that produces pore.
The aluminium alloy production practice prove that hydrogen is unique gas that can be dissolved in a large number in the aluminum or aluminum alloy, are to cause aluminium alloy to form the major cause of pore, and be the most deleterious gas in the aluminium alloy, also be the gas of solubleness maximum in the aluminium alloy.The hole that in casting solidification process, produces owing to separating out of hydrogen, it is long-pending but also be formation of crack not only to have reduced the actual cross-section of foundry goods, and extrusion process and subsequent heat treatment are prone to bubble, cause and scrap.
In sum, at the defective of prior art, need the online air-removal equipment of a kind of casting especially, to solve above-mentioned problem.
The utility model content
The purpose of this utility model is to provide a kind of casting online air-removal equipment, solves the defective of above-mentioned prior art, significantly reduces hydrogen content in the melt, and can play the effect of slagging-off, has improved the quality of casting billet, and is simple in structure, very practical.
The technical problem that the utility model solved can realize by the following technical solutions:
The online air-removal equipment of a kind of casting, it is characterized in that, it comprises a cover body, be provided with some graphite rotators in the described cover body, described graphite rotator is a hollow structure, described cover body top is provided with the drive-motor that is used to drive described graphite rotator rotation, and the top of described graphite rotator is connected with blowing device by pipeline.
In an embodiment of the present utility model, be provided with baffle plate between the described agitating roller.
In an embodiment of the present utility model, described cover body connection one is used to control the rotation regulating mechanism of described cover body level or vertical direction action.
The online air-removal equipment of casting of the present utility model stirs aluminium liquid by controlled rotation graphite rotator, is pressed in aluminium liquid by rotor the rare gas element of metering simultaneously and is dispersed as micro-bubble, and it is evenly dispersed in the aluminium liquid, and the gas dividing potential drop of bubble is zero.Because the hydrogen dividing potential drop height in the aluminium liquid, so the hydrogen in the aluminium liquid constantly spreads in bubble, part nonmetal inclusion in the aluminium liquid is attracted to bubble surface simultaneously, and the adherent rare gas element bubble floating of useless hydrogen and part non-metallic inclusion disposes to liquid level, graphite rotator rises automatically, can carry out the purpose that skimming has reached dehydrogenation and oxide inclusion, improve the quality of casting billet, simple in structure, very practical, realize the purpose of this utility model.
Characteristics of the present utility model can be consulted the detailed description of the graphic and following better embodiment of this case and be obtained to be well understood to.

In the utility model, be provided with baffle plate 150 between the described agitating roller 110.
In the utility model, described cover body 100 connections one are used to control the rotation regulating mechanism 200 of described cover body 100 levels or vertical direction action.
In the utility model, blowing device 140 and rotation regulating mechanism 200 all are to adopt existing equipment, just have not been described in detail at this.
During work, regulate the position of cover body 100 by rotating regulating mechanism 200, cover body 100 can be covered on the founding groove 300, drive graphite rotators 110 rotations by drive-motor 120 then and in founding groove 300, be blown into rare gas elementes such as the nitrogen of processing requirement air pressure or argon gas by the hollow structure of blowing device 140 by graphite rotator 110, remove hydrogen content in the melt, and can play the effect of slagging-off, improved the quality of casting billet, simple in structure, very practical.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
