Description

Technical Field

[0001] The utility model belongs to the technical field of the application of liquid steel detection during casting, and particularly relates to a sampling and transportation device based on high-precision liquid steel. Background Art

[0002] Liquid die forging, also known as squeeze casting and continuous casting and forging, is a new metal forming process that combines the characteristics of casting and is similar to die forging. It directly pours a certain amount of molten metal into a cavity coated with a lubricant, continuously applies a mechanical static pressure, and uses the easy flowability of metal during casting solidification and forging technology to cause plastic deformation of the already solidified hard shell, so that the metal crystallizes and solidifies under pressure and forcibly eliminates shrinkage cavities and porosity formed due to solidification shrinkage, in order to obtain liquid die forging parts without casting defects.

[0003] Liquid die forging has the advantages of simple casting process, low production cost, and complex part shapes, and also has the characteristics of fine grain, uniform structure, good mechanical properties, and high forming accuracy of die forging products. There are mainly the following points: (1) During the forming process, the unfrozen metal liquid crystallizes and solidifies and flows into shape under the action of isostatic pressure from beginning to end; the solidified metal layer undergoes plastic deformation under pressure, has a hot deformation structure, fine grains, and uniform structure. At the same time, the pressure makes the outer side of the part closely adhere to the inner wall of the mold, making the shape and size of the workpiece accurate; (2) Since the first solidified layer undergoes plastic deformation and consumes a part of the energy, the isostatic pressure experienced by the metal liquid is not a fixed value, but decreases as the solidified layer thickens; (3) Under the action of pressure in the solid-liquid zone, forced feeding occurs, which can eliminate defects such as shrinkage cavities and porosity inside the part and improve the mechanical properties of the part; (4) Compared with ordinary hot die forging, the fluidity of the metal liquid is much greater than that of solid metal, and the performance of filling the mold cavity is better, and a more complex part can be formed in one pass with a set of molds; (5) The density and mechanical properties are basically the same as those of die forgings.

[0004] In the metal forming process of liquid die forging, the molten steel needs to be detected. At present, the off-line analysis method is adopted for the analysis of the steel water composition during steelmaking. The general operation is as follows: During steelmaking, the steelworker uses a sampler or a ladle to take samples of the steel water, and sends the samples to the chemical composition analysis laboratory, and uses a direct reading spectrometer to analyze the composition of the sent steel samples.

[0005] In this process, problems such as how to synchronously sample and transport the liquid steel in different melting equipment to the laboratory for detection, and how to prevent heat loss during transportation from affecting the detection results are urgently needed to be solved currently.

[0006] Therefore, based on the above problems, the utility model provides a diversion device for docking liquid die forging steel water and a mold. Content of the Utility Model
