Description
Technical field
The utility model relates to a kind of magnalium aging heat treatment device that is used for.
Background technology
Green manufacturing is the basic model of modernized production Sustainable development; require material conversion process, product life cycle process; all should meet requirement on environmental protection, and optimize to greatest extent and utilize resource and save primary resource, nonrenewable resources and the energy.Lightweight, highly malleablized, precise treatment are manufacturing development trends.The product precise treatment comprises that physical dimension accurately and the specification of quality of dense internal organization two aspects.In materials processing circle, blank and part forming develop to nearly shaping direction gradually.Magnesium alloy is described as the most promising lightweight material in this century, and the application of this material is to energy-conservation great with environment protection significance.And the relative cost of development of magnesium alloy is lower, and it also has the incomparable advantage of other material, and therefore greatly developing magnesium alloy is the major issue of quickening development in science and technology, uplifting the people's living standard.
The sixties in 20th century, magnesium alloy causes people's attention gradually in the application of automobile and field of traffic, but really as the engineering materials of practicality, then is after the eighties in 20th century.Since the nineties in 20th century, automotive industry is for energy-conservation and consideration environmental protection, the trend that the demand of magnesium and alloy thereof is presented fast, grows steadily.Owing to obtained a series of breakthroughs at preparation, the machine-shaping technical elements of magnesium alloy, the production cost of magnesium alloy constantly reduces, and use properties improves constantly, and has promoted the application of magnesium alloy at numerous industrial circles such as automobile, electronics, communication, household electrical appliances greatly.Be to improve magnesium alloy strength and erosion resistance, generally all need ageing treatment after the solid solution.Purpose is to separate out Mg
17Al
12The grade in an imperial examination two-phase reaches the purpose of solution strengthening.The recent research achievement shows, that separates out is second many more mutually, and strengthening effect is good more, the also corresponding raising of erosion resistance.
At present, magnetic field has been in the starting stage to the effect of magnesium alloy research, about the influence of magnetic field to the magnesium alloy solidification tissue, Chinese scholars all second separate out mutually aspect as emphasis research topic, to improve second amount of separating out and make it uniform distribution mutually.Result of study shows, influence is useful to the magnesium alloy crystalline in magnetic field, and its crystal grain thinning improves the mechanical property of magnesium alloy.
China's number of patent application 200610029884.9 had announced once also that a kind of MG-AL was the high-intensity magnetic field ageing hot processing method of alloy, its key step is, after but the MG-AL of timeliness is alloy solid solution, put into the magnetic field of certain magnetic field intensity, in certain stable thermal life processing of carrying out down.It can suppress the discontinuous ratio shared in all are separated out of separating out by high-intensity magnetic field, increases the quantity of separating out continuously, increases the ratio that two classes and three classes are separated out continuously simultaneously, and having improved MG-AL thus is the performance of alloy.But it has only announced the method for this processing, and it is feasible not design convenience as yet, is suitable for the concrete device of practical application.
The utility model content
Technical problem to be solved in the utility model is, provides a kind of simple in structure, convenient feasible in order to overcome above-mentioned the deficiencies in the prior art, is suitable for the actual effect thermal treatment unit of practical application.
For solving the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of magnalium timeliness thermal treatment unit, its characteristics are, comprise housing, and enclosure interior is provided with heating unit, and hull outside is provided with magneticfield coil.Further more specifically, described housing is made by quartzy refractory materials, and heating unit is a nichrome wire, and nichrome wire is arranged between the two-layer quartzy refractory materials of enclosure interior, the preferred adopting quartz glass pipe of described refractory materials when specifically implementing.During use, the magnalium sample places device inside to carry out timeliness thermal treatment, nichrome wire provides electric current by control device to it and aging temp is controlled, it is very convenient to control, the magneticfield coil that is provided with provides AC magnetic field for sample, improve the amount of separating out of alloy second phase, and made it uniform distribution, reached the purpose that improves magnesium alloy strength and erosion resistance.
As optimization, described hull outside two ends are provided with the support that is made of refractory materials, can play device to be convenient to support and heat insulation effect, and this refractory materials can preferably adopt refractory brick when specifically implementing.
The utility model main body is by quartzy refractory materials, and materials such as ceramic refractory constitute, and are with low cost, because magnalium timeliness thermal treatment temp is lower, so the timeliness thermal effectiveness significantly and not influences the performance of magnetic field usefulness; Simultaneously, the magneticfield coil of setting provides AC magnetic field for sample, has improved the amount of separating out of alloy second phase, and has made it uniform distribution, reaches the purpose that improves magnesium alloy strength and erosion resistance.The utility model also possesses simple in structurely in addition, is suitable for advantages such as enforcement.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1, a kind of magnalium timeliness thermal treatment unit comprises columnar housing, and enclosure interior is provided with heating unit, and hull outside is provided with magneticfield coil 6.During enforcement, described housing is made by inside and outside two-layer quartz glass tube 4,2, and heating unit is a nichrome wire 3, and nichrome wire 3 is arranged between the two-layer quartz glass tube 4,2 of housing.During concrete enforcement, described hull outside two ends are provided with the support 1 that is made of refractory brick, can play device to be convenient to support and heat insulation effect.During use, magnesium alloy sample 5 places device inside to carry out timeliness thermal treatment, nichrome wire 3 provides electric current by control device to it and aging temp is controlled, it is very convenient to control, the magneticfield coil that is provided with provides AC magnetic field for sample, improve the amount of separating out of alloy second phase, and made it uniform distribution, reached the purpose that improves magnesium alloy strength and erosion resistance.
During enforcement, resistance wire is 300W (can select power by the size of process furnace during application), is used to heat magnesium alloy, adds (220V, 60W) annular alternating magnetic field coil, for experiment provides magnetic field.For DISTRIBUTION OF MAGNETIC FIELD in testing is subjected to the influence of outside atmosphere less as far as possible, in the laboratory apparatus preparation process, use ferromagnetic material less, and multiselect is with materials such as the silica glass that does not influence magnetic field, potteries as far as possible.
