Abstract
The utility model relates to a reciprocating spurting control forming unit which can manufacture large-diameter, multiform alloys and the composite materials with high density and high performance. The forming unit adopts a multilevel, nonrestrictive and non-scanning atomizing nozzle. Driven by the high-speed and fragmentized inert gases, the metal melt (comprising composite particulate for composite materials) forms a high-speed atomizing jet stream, which has a reciprocating sedimentation movement with a substrate under the online accurate control. The alloy which deposits on the surface of the substrate quickly cools, and thus the sediment with a dense organization, favorable performance and a certain shape will be achieved. The device can integrate the manufacturing of the pipes with different diameters, plates with different thickness and the column ingot together.
Description
Technical field
The utility model relates to alloy and particulate composite preparing technical field thereof.Specifically be meant the reciprocal reaction-injection moulding device of a kind of control.
Background technology
Spray deposition processing is that metal bath is atomized, and high speed deposition is to substrate then, and rapid solidification obtains the method for blank.Compare with casting technique, the setting rate of reaction-injection moulding blank improves 1 more than the order of magnitude, have meticulous, etc. the grain structure of axle, no gross segregation, mechanical property is superior.(RSPM) compares with the rapid solidification powder metallurgical technique, and the oxygen content of reaction-injection moulding blank is low, and comprehensive mechanical property is superior, and forming process is few, and production cost is low, production efficiency height, ratio of performance to price height.The alloy that is deposited on substrate surface is in semisolid, its liquid phase fraction (f
L) be a key control parameter.f
LCross when hanging down, alloy graining feeding deficiency is organized porous, mechanical properties decrease, and the quality recovery rate reduces simultaneously, and cost raises.f
LWhen too high, the alloy graining cooldown rate descends, and organizes as cast conditionization, mechanical properties decrease; Alloy viscosity descends simultaneously, and adhesion strength reduces, and the quality recovery rate reduces, and cost raises.With the Osprey pattern is the conventional spray forming technology of representative, and unidirectional mode is adopted in the relative motion of molten drop injection stream and substrate, and in rotation, horizontal single-headed moves with respect to fixing injection stream in substrate.With the pipe fitting is example, under the Osprey pattern, the outer surface of the sedimentation rate rapid directive substrate of injection stream about with 100m/s, in the outer surfaces of substrates successive sedimentation, increase along with the increase of pipe fitting thickness by the hot-fluid of injection stream to the outer surface transmission of this substrate, when pipe fitting thickness surpassed certain critical value, the deposit rate of heat dispation was lower than the hot-fluid of injection stream, and sedimental temperature rises rapidly and causes f
LSurpass optimum range.Therefore in practice, the thickness of general large diameter pipe fitting can not surpass 20mm.Above-mentioned the analysis showed that, the critical process problem that solves big thickness product are how to make injection stream to be complementary to sedimental input hot-fluid and deposit rate of heat dispation.Multilayer spray forming technology (CN95110862) by people such as Chen Zhenhua, Zhang Hao invention adopts injection stream and substrate to move back and forth, deposit is made up of several layers, under identical surplus genus quality deposition speed, deposit rate of heat dispation in this pattern improves along with the increase of the number of plies, to be significantly higher than the Osprey pattern, ingeniously overcome the as cast condition trend of organizing.But the metallurgical binding state of bed boundary depends on the physical state of presedimentary injection stream and deposition surface.Drop in the injection stream is evenly concentrated before deposition, and the deposit surface temperature is near solidus, and when satisfying these two conditions simultaneously, the bed boundary could obtain best metallurgical binding state.In the multilayer spray forming technology (CN95110862) of people such as Chen Zhenhua, Zhang Hao invention, the problem that exists mainly contains: one, adopt the close coupling nozzle, and can not obtain the injection stream of evenly concentrating, its injection stream is disperseed and is inhomogeneous, causes the junction, interface to form a large amount of holes; Its two, adopt close coupling to spray and lack stable molten metal pressure head, liquid flowing rate instability, and gaging somebody easily can't realize continuous, stable suitability for industrialized production; Its three, technical process lacks the monitoring of key physical state and feedback, does not set up with the technical process Mathematical Modeling that accurately is controlled to be target, causes the instability and the noncontinuity of deposit alloy structure.Under above-mentioned multilayer spray shaping mode, sedimental relative density is lower than 85%, the bed boundary bond strength is low, there are fine and close oxide and a large amount of hole, even through the extruding of follow-up aximal deformation value, processing such as rolling, these oxides and a large amount of pore can't be eliminated, and for improving the mechanical property and the qualification rate of final finished, the meticulous effect of organizing that is obtained than the raising of Osprey pattern by cooldown rate is cancelled.Similarly, severe oxidation takes place in the sedimental inside of porous of traditional multilayer spray forming technology preparation in reheating process, and this brings further infringement for the final mechanical property of product.
No matter existing reaction-injection moulding equipment is Osprey pattern or multilayer spray shaping mode, its production function singleness, can not produce tubing, ingot blank, sheet material on same equipment, the versatility of equipment is poor, and automaticity is low, industrialization has high input, the production cost height.
Summary of the invention
