Description

Technical Field

[0001] The utility model relates to the technical field of metallurgy, in particular to a molten iron sampling device for a molten iron tank car. Background Art

[0002] Molten iron sampling is the process of quickly taking out samples from the liquid molten iron for rapid spectral analysis, so as to obtain the composition, homogeneity and other conditions of the molten iron in the furnace, which is used to guide the smelting process; existing molten iron sampling usually uses a long-handled metal sampling cup. The staff inserts the sampling cup into the molten iron, scoops out the molten iron, and then transfers it to the analytical instrument for analysis.

[0003] The currently published patent: CN217132636U discloses a molten iron sampler. By setting a fixed circular plate, a rotating plate, a connecting rod, an L-shaped connecting rod, a gripping rod, a handle and a sampling block, when in use, the operator holds the two handles with one hand, and through the cooperation of the fixed circular plate, it is convenient to integrate and split the two sampling blocks, which is convenient for one-handed operation and simple to operate. At the same time, the operation range is small and relatively labor-saving. At the same time, the operator can free up the other hand to improve his own safety, and the practicality is high. Therefore, the molten iron sampler is convenient for one-handed operation and simple to operate. At the same time, the operation range is small and relatively labor-saving. At the same time, the operator can free up the other hand to improve his own safety.

[0004] Based on the above search, it was found that the above patent has the following problems when in use: when the molten iron sampler is in use, the staff samples the molten iron through the sampling blocks. Since the tops of the two sampling blocks are not sealed after taking out the molten iron, there are certain risks when sampling with the two sampling blocks. Since the mass of the molten iron is large, shaking is inevitable in the process of transferring the molten iron through the two sampling blocks. The molten iron can easily spill out of the two sampling blocks and scald the staff, which is dangerous. Utility Model Content
