Description
Technical field
The utility model relates to a kind of heavy castings and solidifies analytical equipment, belongs to the metal solidification process analysis field.
Background technology
The heavy castings setting time is long, occurs tissue defects easily.And its weight causes scrapping in case defective occurs all at several tons or more than hundreds of ton, and the loss that causes is inestimable.For this reason, before heavy castings production, must carry out serious analysis, consider the influence to the casting solidification tissue such as composition, treatment process, carry out a large amount of optimization Test,, guarantee the production reliability to prevent defective to casting solidification process.But the testing equipment of analyzing the heavy castings process of setting at present lacks, and technological experiment can only carry out through cast large-scale test block or actual foundry goods, and is not only with high costs, and the test period is long, can't carry out a large amount of tests, for the heavy castings quality control brings difficulty.
More existing thermal modeling test equipment all are directed against the metallurgy rolling process basically at present, use the tissue response in microsize sample simulation heating, cooling, the deformation process, to the slow process of setting of analyzing heavy castings effective help can't be provided.China invention ublic specification of application 200910199568.X discloses and has a kind ofly studied under the outside strong cool condition initial solidification behavior and the accurately method and the implement device thereof of simulation horizontal growth process of solidification structure, but this method can not realize the analysis of heavy castings process of setting.It is the design of the sample quenching apparatus of hot modeling test machine that 200720067245.1 in China's utility model patent instructions has related to Gleeble, with the quick cooling of realization sample, but can't be applied to the slow process of setting of heavy castings.
Summary of the invention
The process of setting of foundry goods, its essence are the processes of a heat dissipation.The basic reason that the heavy castings setting time is long is that its heat dissipation is slow.But the laboratory simulation heavy castings solidify when analyzing, and can only use the small size test block, are difficult to reach real analytical effect.Therefore,,, it is solidified as heavy castings are slow, just can use the small size test block, realize analysis heavy castings process of setting and solidified structure as long as can slow down its heat dissipation speed for the small size test block.
For this reason, the purpose of this invention is to provide a kind of heavy castings and solidify analytical equipment, realize the analysis of the process of setting and the solidified structure of heavy castings is realized through following technical proposal with the lab scale piece.
A kind of heavy castings solidify analytical equipment, comprise heating furnace, crucible, temperature controller, temperature acquisition system, temperature thermocouple, temperature-control heat couple; Said crucible places heating furnace, and the temperature-control heat couple that links to each other with temperature controller is set in the heating furnace, is used for detecting and to temperature controller furnace temp being provided, so that temperature controller slowly solidifies the temperature of required temperature adjusting heating furnace according to test block; The temperature thermocouple that links to each other with temperature acquisition system is set in the crucible, is used for detecting in real time the situation of the corresponding test block process of setting of furnace temp.
Said crucible is for crucible commonly used, like graphite crucible, alundum (Al crucible, silicon oxide crucibles, zirconia crucible.
Said temperature controller, temperature acquisition system are common temperature controller and temperature acquisition system.
During use; Foundry goods is poured in the crucible with alloy liquid; Temperature controller and temperature-control heat couple the holding temperature and the time of control heating furnace, make alloy liquid according to the slow cooled and solidified of the process of setting of heavy castings according to the solidification and crystallization temperature and the setting time of heavy castings; Temperature acquisition system detects the situation of the corresponding test block process of setting of furnace temp in real time through temperature thermocouple.After solidifying end, fabric analysis is carried out in test block, can be realized analysis big casting solidification process and solidified structure.
The advantage of the utility model: this device can accurately be controlled the heat dissipation process of little test block, and it is solidified according to heavy castings are equally slow, can analyze the slow process of setting and the solidified structure of heavy castings; This device has characteristics such as with low cost, reliable and stable, easy to operate.
Description of drawings
Fig. 1 solidifies the structural representation of analytical equipment for the utility model heavy castings.
Embodiment
Below in conjunction with embodiment the utility model is further specified.
Like Fig. 1, heavy castings solidify analytical equipment, comprise heating furnace 1, crucible 2, temperature controller 3, temperature acquisition system 4, temperature thermocouple 5, temperature-control heat couple 6; Said crucible 2 is the alundum (Al crucible; And place heating furnace 1; The temperature-control heat couple 6 that links to each other with temperature controller 3 is set in the heating furnace 1; Be used for detecting and providing heating furnace 1 temperature, so that temperature controller 3 slowly solidifies the temperature of required temperature adjusting heating furnace 1 according to test block to temperature controller 3; The temperature thermocouple 5 that links to each other with temperature acquisition system 4 is set in the crucible 2, is used for detecting in real time the situation of the corresponding test block process of setting of heating furnace 1 temperature.
According to the alloying component and the phasor of foundry goods, confirm its temperature of solidification; According to its thermal center size, confirm its setting time.Set furnace temperature of heating furnace then in view of the above, device brings into operation.Foundry goods is poured in the crucible with alloy liquid 7, and temperature controller and temperature-control heat couple the holding temperature and the time of control heating furnace, make alloy liquid according to the slow cooled and solidified of the process of setting of heavy castings according to the solidification and crystallization temperature and the setting time of heavy castings; Temperature acquisition system detects the situation of the corresponding test block process of setting of furnace temp in real time through temperature thermocouple.
