Specific embodiment
The following further describes the present invention in detail with reference to the accompanying drawings and specific embodiments.
Metallurgy siphon tapping method includes the following steps: as shown in Figs. 1-2
The sealing of 3 one end of high temperature alloy pipes is slidably inserted into smelting furnace 1, and extends to the molten metal liquid of smelting furnace 1
Under liquid level, 3 other end of high temperature alloy pipes accesses thermal insulation pool 2, and setting 2 height of thermal insulation pool is lower than 1 height of smelting furnace;
High temperature alloy pipes 3, thermal insulation pool 2 vacuumize for the first time with vacuum pump;
High temperature alloy pipes 3, thermal insulation pool 2 are preheated by heating device;
Molten metal liquid in smelting furnace 1 drains into thermal insulation pool 2 through high temperature alloy pipes 3 by siphonage;
High temperature alloy pipes 3, thermal insulation pool 2 are vacuumized for the second time with vacuum pump, auxiliary is using pressurization air pump to melting
Furnace 1 pressurizes;
The height of smelting furnace 1 is adjusted with lifting platform 4, and/or is adjusted 3 one end of high temperature alloy pipes with leading screw and nut mechanism 5 and stretched
Enter the height of smelting furnace 1, to adjust the molten metal flow rate of liquid in high temperature alloy pipes 3.
By lift adjustment smelting furnace 1 and/or high temperature alloy pipes 3, to form the regulative mode of two kinds of liquid levels, energy
Enough in the decline of 1 liquid level of smelting furnace, then molten state in high temperature alloy pipes 3 can be adjusted by adjusting the height of high temperature alloy pipes 3
The flow velocity of metal liquid, and since the variation of the flow velocity is that dynamically, smelting furnace 1 and 3 height of high temperature alloy pipes are adjustable
Section, will be so that adjust more flexible;Wherein, high temperature alloy pipes 3,2 first time of thermal insulation pool are vacuumized, is conducive to molten metal liquid
Body initially enters high temperature alloy pipes 3 in favor of forming effective siphon, and preheating then facilitates to reduce molten metal liquid and height
Resistance between temperature alloy pipe 3, thermal insulation pool 2, in favor of improving flow velocity, while also can avoid the preheating suddenly of high temperature alloy pipes 3 and
It cracks;It pressurizes by vacuumizing for the second time, and to smelting furnace 1, it can be to avoid because smelting furnace 1, high temperature alloy pipes 3 be gone up and down
Caused molten metal liquid sloshing and the influence to flow velocity flow molten metal liquid from smelting furnace 1 more stablely
Enter high temperature alloy pipes 3, in this way, by means of the present invention, flow rate of liquid can be made to stablize, and is raised speed relatively, it is highly beneficial
In raising subsequent processing to the efficiency of molten metal liquid handling.
The high temperature alloy pipes 3 of this example are solution strengthening type alloy, and inside pipe wall surface can increase coating heat-stable ceramic layer, to keep away
Exempt from that molten metal solution is possible to react with alloy.
Certainly, the lift adjustment of smelting furnace 1 and high temperature alloy pipes 3 can need to be used to selectivity adjusting simultaneously or be divided according to flow velocity
It does not adjust.Leading screw and nut mechanism 5 then has more accuracy to the height adjustment of high temperature alloy pipes 3.
As preferred embodiment, the both ends of the high temperature alloy pipes 3 of the present embodiment are accessed by high-temperature expansion joint molten respectively
Vibrator is respectively set for providing vibrational energy to high temperature alloy pipes 3 at the both ends of high temperature alloy pipes 3 in furnace 1 and thermal insulation pool 2
Amount.Vibrator can clear up the tiny clinker remained in high temperature alloy pipes 3, to further decrease the flowing of molten metal liquid
Resistance improves flow velocity.High-temperature expansion joint has certain flexibility ability, to adapt to the displacement of smelting furnace 1 and high temperature alloy pipes 3, together
When, high-temperature expansion joint heat expansion, with this can secure seal dock high temperature alloy pipes 3, effectively avoid revealing.It is more highly preferred to
Ground, the high temperature alloy pipes 3 of the present embodiment are divided between two sections, two sections to be connected by hose, is so suitable for 1 He of smelting furnace
High temperature alloy pipes 3 significantly move.
Temperature for the molten metal liquid at each position of uniform thermal insulation pool 2 is kept away in favor of the Rapid Implementation of subsequent processing
Exempt from influence subsequent processing technological effect, this example be arranged thermal insulation pool 2 be it is multiple, a plurality of high temperature alloy pipes 3 are correspondingly arranged, by melting
Furnace 1 divides for upper layer, middle layer, lower layer, and 3 one end of high temperature alloy pipes is respectively connected to the upper, middle and lower, high temperature alloy pipes 3 it is another
One end is respectively connected to different thermal insulation pools 2.In this way, the molten metal liquid of different layers will import thermal insulation pool 2 by siphon simultaneously,
Mix the molten metal liquid of each layer different temperatures in thermal insulation pool 2, temperature is effectively homogenized.
Molten metal liquid is also accidentally connected to extraction when to avoid vacuum pump from vacuumizing high temperature alloy pipes 3, this example is adopted
With anti-filling formula high temperature alloy pipes 3, which meets such as flowering structure: the tube wall of high temperature alloy pipes 3 is provided with multiple pump orifices
32, pump orifice 32 is capped with heat-resisting partition 31 outside, and partition 31 seals shroud to high temperature alloy pipes 3 towards one end of smelting furnace 1
The inner wall interval of inner wall, the one end of partition 31 far from smelting furnace 1 and high temperature alloy pipes 3 forms suction intake 33.In this way, smelting
The molten metal liquid that furnace 1 flows into high temperature alloy pipes 3 is obstructed by partition 31, without entering pump orifice 32 and suction intake
33.It is preferred that also grid can be added in suction intake 33, further to promote the anti-ability for filling imbibition body.
