Description
The present invention relates to the production unit of a kind of alloy or matrix material, particularly jet deposition equipment.
At present, spray deposition technology has been widely used for the production of alloys such as various pipes, slab, excellent base and matrix material, all be the jet deposition principle that has adopted Britain Asinger professor to propose the seventies on this technological essence: being about to that molten metal or alloy atomize in inert atmosphere is that particle jetting liquid flows, inject directly on the colder matrix, through moving to and froly hit, coalescent, be frozen into settling, its common feature is that settling forms through the matrix deposition by spray liquid flow is disposable." Arms Material scientific and engineering " the 17th volume has been introduced the equipment and the technological process of this technology the 2nd phase (in March, 1994).Compare with common casting one press working and powder metallurgy, its apparatus and process is simple, can reduce many manufacturing procedures, the using rate of metal height, and can save a large amount of energy consumptions.Traditional splashing device generally adopts equipment as shown in Figure 1 and Figure 2, comprising crucible 1, nozzle 2, base stop 3, atomizing space 4, vapor pipe 5, transmission mechanism 6, interior device for cooling 7, though its atomization process speed of cooling is higher, reach 10
3-10
5K/t, but deposits cool speed generally only is 10-10
2K/s, simultaneously when the bigger pipe of preparation diameter, heavy-walled tube base, wide and thick slab, finish size often difficulty reaches requirement, because if solve by improving injection density, because condensing rate is unhappy, causes sedimental segregation, grain coarsening, pyrocondensation hole defect, as adopting v type nozzle, shaking scan nozzle or a plurality of nozzle, technology is very complicated again, and sedimental like this size is very limited.
The new installation that the purpose of this invention is to provide a kind of jet deposition to accelerate speed of cooling, increases the size of jet sediment, improves and sprays large-scale blank quality, does not make equipment, process complications simultaneously again.
Jet deposition equipment of the present invention has increased motion control device 8, outer strong device for cooling 9 and web plate 10, the nozzle 2 and the outer conduit 11 of device for cooling 9 by force that fuse with crucible all pass web plate 10, and be fastened on the web plate 10, with the web plate 10 common crucible systems of forming, web plate 10 is promptly as the loam cake of spray chamber 4, motion control device 8 acts on the web plate 10, the motion of control crucible system, and the size and Orientation of its speed all can be regulated.Outer strong device for cooling 9 comprises air feed bottle, switch-valve and conduit 11, and its effect is: after spray liquid flow 13 was sprayed onto on the matrix 3, outer strong device for cooling 9 conduit jet orifices 12 are the shower cooling medium immediately, and settling 14 is carried out external cooling, and its heat-eliminating medium is liquid nitrogen or rare gas element.According to the difference of spraying blank, the movement locus of crucible system and outer strong device for cooling 9 are also inequality, when spraying tubing, as shown in Figure 3, the conduit jet orifice 12 of outer strong external cooler 9 is positioned at matrix 3 belows, and is relative with nozzle 2, and crucible system is made approximate linear uniform motion along the bus of matrix 3, matrix 3 buses are done uniform rotation around its axis again simultaneously, and the deposition track that metal jet liquid is injected on the matrix 3 is a circular helix; When spraying slab, as shown in Figure 4, outer strong device for cooling 9 respectively has a conduit jet orifice 12 in the nozzle both sides, different motion direction according to crucible system, open corresponding conduit jet orifice respectively and close an other conduit jet orifice, heat-eliminating medium is sprayed into after every layer of spray liquid flow 13 depositions just, every surface sediments 14 is carried out external cooling, crucible system is reciprocating along 3 liang of parallel edges of plane tabular matrix, matrix 3 is simultaneously reciprocating perpendicular to crucible system direction of motion, and the deposition track that metal jet liquid is injected on the matrix 3 is a sinusoidal curve.In the moving process, the conduit jet orifice 12 of conduit 11 is constant all the time with the relative position of nozzle.Settling 14 each layers that make so all are the results of crucible system and more than 3 motion of matrix; The homogeneity of alloy or matrix material, planarization all improve greatly than the one-sided motion of matrix.According to different deposit preform sizes, can adjust the move distance of corresponding crucible system, matrix 3, and adjust the movement velocity of crucible system, matrix 3, can satisfy the different performance requirement of deposit preform.
When utilizing aforesaid device to produce alloy or matrix material, the optimum deposition condition of multilayer spray depends on temperature of superheat, gas and mass ratio, jet length and the matrix 3 of metal injection liquid stream of metal liquid, the movement velocity of crucible system.But because matrix 3 to-and-fro movements, in the multi-level jet deposition, a back settling of same position arrives apart from the timed interval that last settling arrives long, last surface sediments ratio is easier to sputter and solidifies, form the sputter border easily, the quality of blank is sprayed in influence, for guaranteeing that back one deck jet sediment arrives the incomplete sputter of last surface sediments before and solidifies, eliminate the sputter border, realize optimum deposition condition, in the processing parameter of production process, the temperature of superheat of molten metal is chosen 100-200 ℃, jet length is with 150～200mm, atomization air pressure is 1～1.21MPa, jet exit footpath 28～30mm, the frequency that matrix 3 rotates or moves (all numbers that the unit time endobasal-body rotates or round mobile number of times) avoids selecting for use the multiple relation with the travel frequency of crucible 1, the general available 1/10～1/6Hz of the motion frequency of crucible, the motion frequency of matrix can be with 1/40～1/30Hz, when needs are made long tube and slab spare, also can use many group crucibles simultaneously, nozzle and conduit jet orifice satisfy optimum deposition condition.In addition, with different crucibles put different molten metals respectively, when strengthening producing matrix material mutually, the homogeneity of matrix material improves greatly.
Owing to adopted above-mentioned technology, accelerated sedimental speed of cooling greatly, make sedimental sedimentation velocity by 10～10
2K/s brings up to 10
3-10
4K/s, when spraying large-scale blank, realize optimum deposition condition easily, increased the size of spraying blank, can produce Φ 270 * 350mm, wall thickness is 30kg for the 80mm quality so that bigger alloy aluminum ingot is compared with crucible or the one-sided motion of matrix, improved the precision of deposition blank greatly, made blank smooth, even.Simultaneously, the uniform distribution of strengthening phase for matrix material again provides a kind of novel method.
