Description

Technical Field

[0001] The utility model relates to the technical field of melt sampling, and particularly relates to a melt sampling device. Background Art

[0002] The preparation method of aluminum matrix composites mainly adopts powder metallurgy preparation method and needs to add reinforcing particles. However, the size of the reinforcing particles is relatively large and there are often sharp corners, where stress concentration is likely to occur around the sharp corners. Moreover, the interfacial compatibility between the reinforcing particles and the matrix is poor, resulting in a serious decline in the ductility of the material and failing to meet the application requirements.

[0003] There is also an in-situ self-generation preparation method in the preparation method of aluminum matrix composites. This method does not require adding reinforcing particles and can generate reinforcing particles by reaction in the melt; the generated reinforcing particles are relatively fine and have good compatibility with the matrix, maintaining a relatively high ductility of the matrix while improving the strength of the material. Therefore, the in-situ self-generation preparation method is an advanced preparation method for aluminum matrix composites.

[0004] In the process of preparing aluminum matrix composites by the in-situ self-generation preparation method, it is necessary to sample on the surface and inside of the aluminum alloy melt for real-time research on the reaction situation of the aluminum matrix composites, so as to adjust the preparation parameters in a timely manner according to the reaction situation to improve the finished product performance of the aluminum matrix composites. However, most of the existing sampling components are sampling spoons, which can generally only sample on the surface of the aluminum alloy melt and sample at close range, and it is difficult to sample deep into the aluminum alloy melt and sample at a long distance, resulting in great limitations in sampling and being unable to accurately and real-time study the reaction situation of the aluminum matrix composites.

[0005] In summary, it is necessary to provide a melt sampling device to solve the problems in the prior art that it is difficult to sample deep into the aluminum alloy melt and sample at a long distance. Content of the Utility Model
