Description
Technical field
The invention belongs to foundry trial equipment technical field, more particularly to a kind of gravity casting simulation testing stand.
Background technology
It is still rule of thumb to determine the casting technological parameters such as discharge coefficient, flow velocity and conjunction at present in conventional cast production
The running gate system of reason, this is very inadequate, and unscientific for some great complicated and of large quantities casting, and casting gives up
Product rate remains high, and often results in heavy economic losses.Molten iron or molten steel need to be gone to casting ladle when being cast in Foundry Production
On production line, alignment sprue gate is poured on the molten iron in casting ladle or molten steel in the sprue cup of casting workpiece, by knockout after cooling
Cleaning forms casting.At present, casting molten iron or molten steel are the heavy casting ladles of handling of being lifted or driven a vehicle by worker's hand, at high frequency furnace
Molten iron or molten steel are connect, then molten iron or molten steel are moved on to casting place with casting ladle, two people or more people coordinate, casting ladle inclined at leisure
Tiltedly, the molten iron in casting ladle or molten steel are poured in the sprue gate of workpiece.Such a method is not easy to on-the-spot teaching or experimental study,
Main restricting factor has：(1) limited by electricity consumption, general Foundry Production is all carried out at night, is not easy to carry out participation number
The experimental study that more teaching or needs is debugged；(2) it is poor to cast work on the spot environment.The temperature of molten iron or molten steel is up to 1500
DEG C or so, for its operating ambient temperature more than 40 DEG C, potential safety hazard is big；(3) working environment is dangerous, and the moment is careful molten iron or steel
Fine grinding is splashed, and the personal safety guarantee of field personnel has hidden danger；(4) the cast-in-place whole process cycle is longer, and casting rate is slow；
(5) cast-in-place experimentation cost is high.In terms of the teaching of casting process, research is related to, the teaching in terms of casting is all base
The oral account of Yu teacher or master worker and video teaching, few students can personal understanding casting process, in terms of causing to casting
Many knowledge only rest on the stage of empty talk.And received what is visited by the arrangement of the opportunity of visit, scene to site visit
The many restrictions such as condition, safety management and traffic, once imparting knowledge to students will often expend a great deal of time with energy in preparation and group
Knit.The workload of organizing preparation is not only increased, improves instruction cost, and casts on-the-spot teaching and certain peace also be present
Full hidden danger and management difficulty.Therefore, numerical simulation and the physical simulation experiment based on hydraulic analogy turn into the scene of replacement
Casting experiment carries out a kind of Main Means of teaching and scientific research experiment.Meanwhile with the development of Foundry Production technology, measuring technology
With application of the computer in Foundry Production and research, and the raising to casting quality requirement, there is an urgent need to lead in laboratory
The method for crossing physical analogy and mathematical simulation, to the main process of Foundry Production --- cavity filling process and process of setting, carry out essence
True measurement, study its rule, draw qualitative and quantitative mathematical formulae.So as to measure some unknown phenomenons, and with
Rule obtained by laboratory goes to instruct and control production process, improves the quality and yield of casting, and then obtains more preferable
Economic benefit.
Although computer based method for numerical simulation is with certain reference value, error is larger, and many works
Skill parameter can not be obtained by the method for computer simulation.Some external factories from the seventies in last century begin to for it is great,
Casting complicated and that batch is larger, technique study cavity filling process and the cast system of Fluid Dynamics are generally first used in the lab
System, finds out its rule, it is determined that most rational process program, is then produced, to obtain optimal economic effect.
Fluid Dynamics technology turns into the research method commonly used in cast casting optimization design, and preferable casting technique is set
Meter can effectively mitigate the volume gas in liquid metal cavity filling process and be mingled with tendency.Research process is not only in that the aobvious of flow process
Show and the supplement to Computer Numerical Simulation process, and with modern computer technology, image processing techniques and laser skill
The development of art, PIV liquid flow field visualization techniques are such as utilized, it is right using the effective algorithm of computer graphics high speed
The flow field figure picture of acquisition carries out Quantitative study.But have to the similitude of Fluid Dynamics process and liquid metal cavity filling process higher
It is required that higher requirement is proposed to the Test-bed Design of Fluid Dynamics, so as to improve the accuracy of water analogue test result.
For the research in terms of casting experimental simulation device and method, existing literature it is also proposed some solutions.Example
