Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1, this high-speed steel spraying forming device reaction chamber 1 and the settling vessel 2 being arranged in reaction chamber 1 and setting
The tundish 3 above reaction chamber 1 is set, there is the cavity for molten metal of putting upside down, the bottom of tundish 3 is equipped in tundish 3
For pouring out the leak 4 of molten metal, the bottom of settling vessel 2 is equipped with the driving part for driving it to carry out continuing turnover, leak 4
Side be additionally provided with cylinder and air compressor 5 for storing nitrogen, the gas outlet of air compressor 5 is arranged by leak 4
Side, and gas outlet goes out liquid direction, the inclined bottom surface setting of tundish 3 towards leak 4, and the virtual extended line of leak 4 passes through
The upper surface of settling vessel 2, there are two leak 4, and the two leak 4 are different relative to the height and position of the bottom surface of tundish 3,
The middle lower leak 4 in relative position is bellmouth, and the higher leak 4 in relative position is straight hole, and 4 bottom of leak passes through universal joint
It is freely rotated and is connected with a nozzle 6, nozzle 6 is connected to leak 4.
As shown in Figure 1, the metal molten steel under molten condition is poured into centre after dissolving in crucible and with certain flow velocity
In packet 3, the molten metal of the outflow of 3 bottom of tundish should be poured out downwards under self gravitation effect perpendicular to ground,
Enter to do not stop turnover sedimentation basin on to complete sprayup process.But the design is due to devising one in 4 side of leak
Cylinder and air compressor 5, nitrogen under the action of air compressor 5 in sending down abnormally ascending cylinder are extracted out and rush at stream with given pace
Liquid, so flow liquid can be provided to obtain the momentum of side one at this time, makes it since nitrogen is to rush at flow liquid from the side of flow liquid
Flow direction, which generates drift angle, promptly can be dissolved into atomization molten steel for flow liquid moreover, nitrogen is a cold air, moreover, in atomization steel
After liquid is gradually distance from leak 4, it can gradually expand and receive, so it is formed tapered molten steel atomizer (atomizing) cone shown in figure, and metal
Mist jet is to settling vessel 2 during this, and the drop of high-speed flight when colliding on settling vessel 2, made by impact by spheric granules
It is flat with will become, sputtering piece is formed, the cooling effect of settling vessel 2 is then passed through, these particles can cool down rapidly, and certainly
The lower accumulation molding of fusibleness effect, this just completes the whole process of injection molding.
In the design, the bottom of tundish 3 uses two leak 4, and the hole shape of the two leak 4 is different, and one
For straight hole, another is bellmouth, and all initial momentums for spraying molten steel also difference, these power are first is that there is leakage
What the shape of mouth 4 determined, second is that the pressure for having leak 4 to generate relative to the difference in height on molten metal surface determined, just as shown in figure 1
Two leak 4 of display, the leak 4 in left side is since pressure is big, so the metal flow quantity sprayed from here is initial
Momentum also can more greatly, and the original metal amount of surging that right side leak 4 is sprayed then can be smaller, shows so also just producing in figure
, different leak 4 are injected in the different effect in the position on sedimentation basin.
Certainly, specific eject position is main or is adjusted by the height of liquid level in control tundish 3 come and by experiment
What examination determined.After this method, regardless of any position on 2 surface of settling vessel, the pyrosol that can be ejected into all can be relatively
To be uniform, so the uniformity for the precipitating steel pad being preferably formed as also can be very good.
As shown in Fig. 2, being detachably equipped with a partition 7 furnished vertically, 7 energy of partition in tundish 3 between two leak 4
Cavity is divided into two sub- chambers, the position lateral separation in same level height offers several through-holes 8, through-hole 8 on partition 7
It is interior to be detachably equipped with mouth.
Because the holding cavity structure of tundish 3 has been fixed, the liquid level of cavity inner metal liquid anyway is adjusted,
The metal flow velocity gone out from two leak 4 is all fixed between each other, from the angle of mathematics, the molten metal of two leak 4
The variable of flow velocity only one, that is, the liquid level of 3 inner metal liquid of tundish.This can make two 4 eject positions of leak
Regulative mode extremely limits to, and general says, can not adjust second leakage under conditions of first injection of leak 4 dynamics is certain
Mouthfuls 4 injection dynamics, because the injection dynamics for changing second leak 4 is intended to change this variable of liquid level, and this
The injection dynamics of first leak 4 can change again after variable changes.
So the design is also detachably provided with a partition 7 between two leak 4, cavity is divided into two by partition 7
Sub- chamber, and the corresponding leak 4 of a sub- chamber, that is to say, that the injection dynamics of the leak 4 below respective sub- chamber only should
The liquid level of leak 4 determines, and can be opened and closed how many a through-holes 8 on partition 7 with unrestricted choice, and deflecting adjusts two sub- chambers
The stationary value of liquid level.
As what is shown in Fig. 2, constantly pour into the molten metal in cavity, the sub- chamber in left side can be poured into first, then again by every
Partial through holes 8 on plate 7 are poured into the sub- chamber in right side, and during this, people also need to adjust these several through-holes on partition 7
8 quantity being actually opened and closed, such as from the flows per unit time that the sub- chamber in left side is poured into the external world be A, and the sub- chamber in left side is fallen by through-hole 8
Enter to the sub- chamber in right side flows per unit time be B, at this moment two respective flow velocitys of leak 4 just need be two variables of A and B simultaneously
It determines.Rather than as above-mentioned, only determined by A merely, then people only need to debug this variable of B, energy
The relative adjustment of two 4 flows of leak is realized, to meet a variety of different process requirements.
