Description
Technical field
The utility model relates to a kind of degassing device for aluminum alloy melts, belongs to degassing device for aluminum alloy melts technical field.
Background technology
In recent years, along with the promotion of energy-saving and environmental protection idea, various vehicles are one after another to lightweight future development.At present, be that sedan limousine or truck great majority have all been eliminated heavy steel wheel hub, and selected the aluminum alloy forged hub of lighter weight.Aluminum alloy for automobile wheel hub, no matter be for casting or forging, all belong to Al-Mg-Si and be associated gold, just forge with aluminium alloy composition more more complex than casting alloy, these alloys inevitably can produce nonmetal inclusion material in alloying process, can suck gas (being mainly hydrogen), the gentle body burden of nonmetal inclusion material that reduces and reduce in aluminium alloy is one of master operation in aluminium alloy smelting process simultaneously.
The nonmetal inclusion great majority that aluminium alloy produces in producing are oxide compounds, and its fusing point, all higher than aluminium alloy, exists with solid in aluminium alloy melt, and its proportion differs in size, and have much close to aluminium alloy proportion, so they can be suspended in aluminium alloy melt.Aluminium alloy can produce a large amount of hydrogen in fusion process, if process not in time the hydrogen producing in aluminium alloy smelting process, these hydrogen can be absorbed by aluminium alloy solution.In aluminium alloy solution process of cooling, solubleness will constantly decline, hydrogen in liquation also will constantly be separated out thereupon, when the hydrogen content in aluminium alloy solution surpasses certain density, some hydrogen gas bubbles that have little time floating can be trapped in along with the reduction of molten aluminium alloy temperature and in molten aluminium alloy, form micropore, " pin hole " being namely commonly called as, the formation of " pin hole " not only can affect the smooth finish that aluminium alloy is forged face, but also can directly have influence on intensity and the mechanical property of aluminum alloy casting.
In aluminium alloy, whether contain nonmetallic substance be mingled with and air content number, be the major criterion of weighing aluminium alloy quality.At present, in aluminium alloy smelting process, what for the method that reduces nonmetal inclusion material and air content, mainly adopt is rare gas element purifying method, in fusion process toward the rare gas element of jetting in molten aluminium alloy, after contacting with aluminum melt, rare gas element can produce bubble, due to rare gas element discord aluminium generation chemical reaction, rising along with rare gas element, hydrogen in aluminum melt and nonmetal inclusion material are carried under one's arms out, to reach, reduce the nonmetallic substance that is mingled with in molten aluminium alloy and the object of gas.
At present, in aluminum alloy smelting production process, what mainly adopt is a kind of rotor-type refine equipment on line, this device is used motor to drive turning axle, turning axle drives blade rotary, and rare gas element is injected in molten aluminium alloy, by turning axle like this, hydrogen can overflow under the drive of rare gas element in molten aluminium alloy, thereby reaches the object of removing hydrogen in liquation.Due to this rotor-type refine equipment on line complicated structure, volume is large, and floor space is large, and production cost is high, is not suitable for the penetration and promotion in all aluminum alloy smeltings manufacturing enterprise.
Utility model content
The purpose of this utility model is that a kind of degassing device for aluminum alloy melts is provided in order to address the above problem, and this degasifying device is without driven by motor, and volume is little, simple in structure, and production cost is low, easy to operate; The rare gas element bubble that this degasifying device sprays is little, and quantity is many, can more thoroughly hydrogen in molten aluminium alloy be taken out of, reaches purifying aluminum alloy liquation, improves the object of quality of aluminum alloy casting parts.
In order to achieve the above object, the utility model is to adopt following technical scheme to realize:
A kind of degassing device for aluminum alloy melts, it is partly comprised of inlet pipe, handle, airway, carbon tube, it is characterized in that: the rear end of inlet pipe is provided with handle, the end, rear end of inlet pipe is provided with joint, the front end of inlet pipe is welded with airway, is provided with several holes on airway, on hole sidewall, is provided with screw thread, hole place at airway has been threaded connection carbon tube, and the lower end of carbon tube is provided with venting hole.
Using method:
First, outside rare gas element is connected with the joint of end, inlet pipe rear end with flexible pipe, rare gas element is delivered in carbon tube by inlet pipe, and rare gas element can be from the venting hole ejection of carbon tube lower end.During use, as long as this degasifying device being placed in to the bottom in aluminum alloy smelting pond stirs, the rare gas element that carbon tube lower end venting hole sprays can with molten aluminium alloy in pond in hydrogen react, then by rare gas element, hydrogen is taken out of from molten aluminium alloy.
The utility model mainly has following beneficial effect:
This degasifying device is without driven by motor, and volume is little, simple in structure, and production cost is low, easy to operate; The rare gas element bubble of this degasifying device ejection is little, and quantity is many, can more thoroughly hydrogen in molten aluminium alloy be taken out of, reaches purifying aluminum alloy liquation, improves the object of quality of aluminum alloy casting parts.
