Description of drawings
Fig. 1 is the structure chart of metal fibre process units of the present invention.
The specific embodiment
Referring to Fig. 1, the process units of metal fibre of the present invention comprises metal molten system 1, insulation compression system 2, fiber coolant system 3 and vacuum system 4.Metal molten system 1 is in order to the deposite metal.Insulation compression system 2 is connected in metal molten system 1, in order to molten metal is incubated pressurization.Fiber coolant system 3 is connected in insulation compression system 2, and in order to receive and to cool off the deposite metal of ejecting from the insulation compression system, said vacuum system is connected in said metal molten system and said insulation compression system, for it provides vacuum environment.Metal molten system 1 and insulation compression system 2 shared cover vacuum systems 4 are through valve 5 control isolation or together with vacuum system 5 and insulation compression system 2.
Metal molten system 1 concrete structure comprises: vacuum melting furnace 6, fusion crucible 8, running channel 9, gross porosity filter screen 10.Temperature measuring mechanism 7 is inserted from vacuum melting furnace 6 upper ends, in order to measure the temperature in the vacuum melting furnace 6.Fusion crucible 8 is positioned at vacuum melting furnace 6, and can tilt mobile (along the direction shown in the arrow among Fig. 1).Running channel 9 (or claiming chute) passes vacuum melting furnace 6 bottoms and leads in the insulation compression system 3.And a gross porosity filter screen 10 is installed in running channel 9 upper ends.
Cast metals is passed through eddy-current heating; Vacuum fusion and refining; Afterwards; The liquation vacuum condition is poured in the insulation plus-pressure furnace through the one-level coarse net filtering down, and whole process is carried out under vacuum condition or inert atmosphere protection, and this can have been avoided the burning product to generate to greatest extent or other add the entering of slag.
The concrete structure of insulation compression system 2 comprises: insulation plus-pressure furnace 11, insulation crucible 12, water-cooled valve 13, inflation inlet 14, nozzle 15, airtight valve 16, fine mesh screen 17.
Liquation flows through running channel, filters through the secondary fine-structure mesh to get in the insulation crucible 12, and insulation crucible 12 adopts the resistance heated insulation can reach the purpose of accurate control melt temperature, and error is at ± 5 ℃.Exert pressure and pressure release through automatic control gas, accurately control operating pressure.Feed the inert gas (nitrogen or argon gas) of 0.1-2.0MPa in the insulation plus-pressure furnace 11, guarantee the smooth ejection and the moulding of fiber.
Total implementing process flow process: vacuum fusion metal-purification slagging-off-cast-insulation-pressurization-ejection fiber-fiber cooling.
Specifically, at first the metal derby that cuts is put into the crucible of vacuum drying oven, vacuumized (running hours need be opened the vacuum drying oven valve) at every turn; The energising deposite metal, stirring degassing leaves standstill refining; After treating that thermometric reaches requirement, crucible 8 is toppled over cast, through being cast to behind the double-stage filtering (gross porosity filter screen 10 is contained in and waters the road junction) among the insulation crucible i (fine mesh screen adorns 17 at insulation crucible top); Move (through the action of hydraulic means 22) on the running channel 9, close water-cooled valve 13 and isolating valve 5.Heat up in the holding furnace, treat that liquation reaches certain temperature after, charge into inert gas by inflation inlet 14, the pressurization winding-up is through automatic control with regulate the pressure stability that keeps in the stove.Meanwhile, vacuum melting furnace begins the fusing of next stove material, before charging, clears up gross porosity filter screen and fusion crucible (can change like needs).When the liquation in the insulation crucible drops to certain position, stop winding-up, pressure release; Open the bits or the replacing of bell cleaning fine mesh screen, valve-off 16 then, close the vacuum drying oven valve; Open isolating valve 5 and vacuumize, identical with vacuum drying oven vacuum after, open valve 13; Running channel moves down cast, realizes semi-continuous working.
After the fiber ejection gets into cooling storehouse 1, according to the specification of making fiber and quality needs adjustment firsts and seconds cooling condition.
For the aluminium of easy formation surface oxidation protective films, can utilize above-mentioned purification, filter, keep 5 valves to close always, valve 16 is opened always, cast under non-vacuum condition, the ejection of exerting pressure then.
For the metal and the material of easy oxidation, on the basis that said process is implemented, can transform the cooling storehouse, feed inert gas shielding, and the cooling that circulates.
For the high cleanliness fiber pipe nipple or the metal dust that need the production size below 20mm, be equally on the basis of this equipment, with reference to the cooling storehouse design of powder process this storehouse is transformed.
To the requirement of different metal materials and fiber dimensious, can regulate circulating water flow, the water pipe material realizes the parameter change of one-level cooling with arranging; Regulate the flow and the direction of bottom blowing gas flow hole and control secondary cooling effect and fiber heading, guarantee that like this fiber not only helps moulding but also can cool off rapidly, and form certain-length, orderly whereabouts.
