Description
Technical field
The utility model relates to Metal Melting casting equipment, particularly relates to aluminum i ndustry production field, is specifically related to a kind of degassing rotor.
Background technology
Degassing rotor is used for melt degasification during Al and Alalloy refining, and refinery gas, except the refinery gas used mixedly (being generally rare gas element), is then broken up by the rotation of rotor the bubble forming aluminum melt degassing by passing hole channel input.The material of existing degassing rotor generally selects the materials such as graphite, silicon carbide compound silicon nitride and aluminium titanates; there is following shortcoming: not the washing away of the aluminium of resistance to melt liquid, wear away, thermo-labile impact; rotor matrix fragmentation, cracking is produced in work; work-ing life is short; usually 20 days to 50 days are only had; need often to shut down, stop production line; change, overhaul rotor; both affected production continuous, carry out in order; cause batch production quality unstable simultaneously; cost increases, and causes a hidden trouble to again operator's personnel safety.
Utility model content
In view of the above-mentioned shortcoming of existing degassing rotor product, the purpose of this utility model is to provide a kind of degassing rotor, is applied to aluminum i ndustry and produces, have better properties.
In order to achieve the above object, the scheme that the utility model is taked is:
A kind of degassing rotor, its material is silicon nitride ceramic material; The rotor comprising a bull stick and be threaded connection with bull stick one end;
The uniform some air channels of described rotor radial;
Described bull stick has a central through hole.
Further, described air channel is type semienclosed.
Further, described rotor is discoid.
Further, the uniform some stirrer gears of described rotor radial, the shape of described stirrer gear gradually opens spiral line type.
Further, the quantity of described air channel is 4 ~ 8.
Further, described stirrer gear is identical with air channel quantity, and is arranged between two adjacent air channels.
As mentioned above, by taking said structure, degassing rotor of the present utility model is alternative existing: graphite, silicon carbide compound silicon nitride, the like product of the materials such as aluminium titanates, the silicon nitride material that the utility model adopts can resistance to 1500 degree of high temperature, less than 800 degree all can keep original intensity, heat shock resistance, preventing corrosion from molten metals, high rigidity, high strength, abrasion performance, electrical isolation, low heat conductivity, stable chemical performance, react with molten aluminum liquid hardly, volatilize because reacting with oxygen when it heats up, with graphite graphite, silicon carbide compound silicon nitride, the like product of the materials such as aluminium titanates is compared, there is higher work-ing life.The production fields such as aluminium section bar, aluminium foil, low pressure aluminum casting can be widely used in, there is larger Social and economic benef@, and belong to Green Product.
Accompanying drawing explanation
Fig. 1 is the front view of the utility model embodiment rotor.
Fig. 2 be in Fig. 1 A-A to sectional view.
Fig. 3 is the vertical view of the utility model embodiment rotor.
Fig. 4 is the assembling schematic diagram of degassing rotor in the utility model embodiment.
Embodiment
For making above-mentioned feature and advantage of the present utility model become apparent, special embodiment below, and coordinate institute's accompanying drawing to be described in detail below.
Embodiment:
Degassing rotor as shown in Figures 1 to 4, its material is silicon nitride ceramic material; The rotor comprising bull stick and be threaded connection with bull stick end; Uniform 6 air channels of described rotor radial; Described air channel is type semienclosed.Described bull stick has a central through hole.Described rotor is discoid.Uniform 6 stirrer gears of described rotor radial.Described stirrer gear both sides are arc, and side arc radian is greater than opposite side arc radian.Certainly, according to different operating modes, the quantity of air channel and stirrer gear also can be chosen between 4 ~ 8, and the utility model does not limit this.
Degassing process flow process
Principle of work: place degasifying device between holding furnace and casting machine, in degassing processing pond, rare gas element passes in the aluminium liquid of melting by the centre hole of bull stick, nitrogen or the rare gas element chopping of aluminium alloy melt will be blown into by the silicon nitride rotor rotated, form a large amount of disperse bubbles, aluminum alloy melt is fully contacted in treating pond with nitrogen or rare gas element, according to draught head and surface adsorption principle, bubble absorbs the hydrogen in melt in the melt, and adsorption and oxidation slag inclusion is (large in the mode of collision, little of radial interception mode) after rise to melt surface form scum silica frost.And aluminium alloy melt flows to casting machine from the outlet (being located at scum silica frost bottom) of degasifying device, aluminum alloy melt enters degasifying device continuously, and nitrogen is blown into continuously, along with constantly carrying out of purifying treatment, reaches the object of purifying aluminum alloy liquid.
As mentioned above, degassing rotor of the present utility model, adopt between its rotor with bull stick and be threaded, installation is changed quick, easy to use; Air channel is type semienclosed, ensures the bulk strength of rotor, increases the service life; The stirrer gear (blade) of rotor gradually opens spiral line type, is convenient to better gas dispersion.Silicon nitride material adopts air pressure, hot pressing or hot isostatic pressing method to produce, and has better performance.
Although the utility model describes as above with aforesaid embodiment, it can not in order to limit the utility model.Those of ordinary skill in the utility model art, not departing from spirit and scope of the present utility model, does a little change and modification, all in protection domain of the present utility model.Therefore protection domain of the present utility model is when being as the criterion with the claim person of defining.
