Description
Technical field
Novel a kind of alloy melting stove, the particularly a kind of rotten stove of relating to of this use based on composition complementary melt Temperature Treatment technology.
Background technology
Silumin has proportion little, good wear-resisting, thermotolerance and low thermal coefficient of expansion, is easy to plurality of advantages such as casting, is a kind of ideal material that replaces iron to prepare vitals such as piston of automobile, connecting rod, air conditioner compressed machine rotor and blade.Be widely used in the industrial production sectors such as Aeronautics and Astronautics, automobile, shipbuilding, machinery.But be thick polygonal form growth because of the primary silicon in the solidified structure of silumin is mutually more, seriously isolated matrix, worsened the performance of material, limited it in industrial widespread use.Therefore, must change the silicon phase morphology in the alloy, reduce its weakening effect substrate performance.Method to silicon phase thinning processing mainly contains at present: add the alterant method, ultrasonic vibration method, Quench method, low temperature casting, pressure casting method, electromagnetic stirring method, flash set technology, solid-liquid mixed casting treatment process, Overheating Treatment and electricimpulse technology etc.Wherein studying technology more and that production is upward common is to add the alterant method, but modification process is comparatively complicated usually, is difficult to control, and the adding of alterant element also can often not reach intended purposes to alloy and environment generation pollution; Additive method is not that effect is not remarkable, is exactly that technical qualification complexity, cost are too high, is not suitable for carrying out large-scale commercial production.
Based on composition complementary melt Temperature Treatment technology is in proportion through after mixing with different two kinds of alloy melts different with temperature of composition, form the melt treatment of the another kind of composition that requires, and then mixed melt carried out Overheating Treatment, make and to contain second thick hard crisp refinement or the rotten treatment process of obtaining mutually, especially for the unusual significant effective of the rotten processing of transcocrystallized Al-Si alloy.After this kind composition complementary melt Temperature Treatment art breading, the crystal grain that contains primary silicon phase in the 20%Si aluminum silicon alloy can be stabilized in about 40 μ m in insulation 100min inside dimension.This technology is not added other alterant, does not increase cost, is that a kind of technology is simple, and handiness is strong, the novel process of green non-pollution, and effectively improve silicon phase particle form, size and distribution, improve the Al-Si Alloy Modification Effect technology of its mechanical property.
Summary of the invention
The purpose of this utility model is to provide a kind of alloy modification stove, and this equipment can be based on above-mentioned technology, realizes the hypereutectic al-si aluminium alloy or contains the rotten processing of second hard brittle other alloys.
Of the present utility model being characterised in that, a kind of alloy modification stove comprises I resistance furnace and II resistance furnace, described I resistance furnace communicates with the II resistance furnace through transport pipe, is provided with whipping appts in the described II resistance furnace.
Remarkable advantage of the present utility model is: by the melting that two relatively independent smelting furnaces carry out two kinds of alloys respectively is set, make the quality of two kinds of alloys before mixing to be well controlled; Two smelting furnaces carry out UNICOM by a delivery conduit that is provided with cooling water pipeline, make the alloy in the I stove in the process of transport pipe inflow II stove, both can cool off and produce pre-crystalline state, for the alloy melt in the refinement II stove provides the forming core particle, the size that can regulate cooling-water flowing by the valve of control on the transport pipe, thereby the speed of cooling that can regulate alloy; The II stove is divided into hybrid chamber and cast chamber through a dividing plate, after alloy fully merges in hybrid chamber and carries out the insulation of for some time, by opening the valve port that connects two stoves, can be put into the cast chamber and is incubated casting mixing melt after overheated; Adopt the processing of going bad of this equipment, can effectively guarantee rotten fully carrying out of handling, device structure is simple, is easy to make.

Fig. 2 is the structural representation of the utility model transport pipe.
Descriptive name: 1, I resistance furnace 2, II resistance furnace 3, transport pipe 4, whipping appts 5, whipping appts upper vent 6, dividing plate 7, hybrid chamber 8, cast chamber 9, UNICOM's valve port 10, cooling water pipeline 11, water-in 12, water outlet 13, thermopair 14, bell 15, valve 16, gear 17, grate
Embodiment
A kind of alloy modification stove, comprise I resistance furnace 1 and II resistance furnace 2, it is characterized in that, described I resistance furnace communicates with the II resistance furnace through transport pipe 3, be provided with whipping appts 4 in the described II resistance furnace, the bull stick of described whipping appts is the hollow bull stick, described hollow duct upper port 5 is connected with nitrogen or argon gas vent line, described whipping appts bottom is provided with the derivation micropore of nitrogen or argon gas, the furnace chamber of described II resistance furnace forms hybrid chamber 7 and cast chamber 8 through dividing plate 6, is provided with UNICOM's valve port 9 between described hybrid chamber and the cast chamber.
For the alloy to the I stove cools off, be provided with cooling water pipeline 10 in the tube wall of described transport pipe, an end of described transport pipe is provided with water-in 11, and the other end is provided with water outlet 12, can realize adjusting to speed of cooling by regulating flow velocity.
Describe below in conjunction with 1 pair of principle of work of the present utility model of accompanying drawing:
At two furnace melting aluminum silicon alloys, wherein a stove is a hypoeutectic al-si alloy respectively, and another stove is hypereutectic aluminium alloy; After each is incubated 30 minutes, open valve, then the melt in the I burner hearth can flow in the II burner hearth by transport pipe, in this process, flow into the II burner hearth after the cooling of the melt process transport pipe internal cooling water in the I burner hearth, because the unexpected decline of melt temperature, produce pre-crystalline state, produce the crystal grain forming core phenomenon of growing up in other words in the melt, this moment, a large amount of nucleus just appearred in the alloy melt through supercooling tube, for transcocrystallized Al-Si alloy melt in the refinement II burner hearth provides the forming core particle.Melt in the II burner hearth is mixed by the gear driven whipping appts again, at whipping process, feeds nitrogen or argon gas the aluminium silicon melt is carried out degasification.By the time after being incubated certain hour,, being put in the cast chamber of II burner hearth and being incubated casting mixing melt after overheated again by opening the aluminum silicate fiber plunger.
