Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, is only used for explaining the present invention, and is not considered as limiting the invention.
The specific steps of casting alloy product quality detection method according to embodiments of the present invention are described below with reference to Fig. 1.
As shown in figure 1, casting alloy product quality detection method according to embodiments of the present invention, comprises the following steps：
S1：By furnace alloying to molten condition, during refining, contained using sampling instrument from furnace and take conjunction
Golden liquid sample；S2：Alloy liquid sample in sampling instrument is poured into mould and cooled down to generate detection sample；S3；Detection
Detect the product quality of sample.
It is understood that furnace alloying is to molten condition, it is aluminium alloy by process product during refining
Body takes out part and imported in mould, and after alloy liquid cools down generation detection sample completely, the quality of detection detection sample can be with
The alloy solution of furnace is prejudged in the quality as final products.If testing result is satisfied the criteria, the conjunction in furnace
Gold solution is used directly for casting.But if testing result is not inconsistent standardization, that is to say, that detection sample is the qualified production in portion
Product, it is believed that the alloy solution existing defects in furnace, it is impossible to be directly used in casting.Staff can with according to testing result,
Working condition, raw material components to furnace etc. adjust, and are then repeating above-mentioned detecting step.The casting of the embodiment of the present invention
The quality of casting alloy product can be predicted by making alloy product quality determining method so that staff can adjust smelting in time
Parameter, so as to improve the qualification rate of product, probability of doing over again is reduced, saves prime cost.
Casting alloy product quality detection method according to embodiments of the present invention, by using sampling instrument in alloy solution
Contained during refining process and take alloy and generation is detected into sample, staff can predict casting by detecting the product quality of sample
Make the quality of alloy product.
In certain embodiments, step S3 also comprises the following steps：Q1：The surface crystallization situation of observation detection sample is to examine
Survey air content, the dregginess of detection sample.It should be noted that the form of surface crystallization being capable of reaction detection to a certain extent
The air content and dregginess of sample outer surface, and detect sample surfaces crystalline condition can represent to a certain extent casting close
The surface crystallization situation of golden product.Therefore, staff can predict casting by detecting air content and the dregginess of sample
