Description

Technical Field

[0001] The utility model belongs to the technical field of steelmaking, and in particular relates to a convenient steel sampling device for refining. Background Art

[0002] In the steel industry, the composition of steel samples is an important basis for testing whether steel products are qualified. Therefore, in the process of steel smelting, steel samples must be extracted from molten steel and cooled and solidified into shape, and then the formed steel samples must be quickly demolded for component analysis by the spectrometer so as to respond to the smelting process in time, thereby ensuring that the smelted steel products meet the standard requirements. The sampling process is as follows: immerse the molten steel sampler in the molten steel for 4 to 6 seconds, so that the molten steel flows into the sampler to form a steel sample, and then lift it up after immersion for 4 to 6 seconds, and then immerse the sampler in cold water for 10 seconds, so that the steel sample is cooled and solidified into shape by means of quenching.

[0003] At present, the existing molten steel samplers on the market, such as the "A Rapid Molten Steel Sampling Device" disclosed in the Chinese Utility Model Patent Application No. 201922416147.X, are used to extract steel samples, and can cool and solidify the steel samples in a chilled manner. When the steel samples need to be cooled by natural air cooling, their internal structure can accelerate the natural cooling time of the steel samples, thereby accelerating the solidification of the steel samples. However, the device still has the following disadvantages: since the molten steel sampler is wrapped in high-temperature molten steel during sampling, and the temperature drops sharply and solidifies after leaving the molten steel, the steel sample is difficult to demold by shaking alone, and it needs to be knocked dozens of times manually to demold. During the knocking process, the high-temperature molten steel remaining in the molten steel sampler will produce sparks and splash everywhere. Despite wearing a protective mask, the staff still has the risk of being scalded; and in the process of knocking the molten steel sampler, the broken slag inside it will be scattered everywhere, and the staff will waste time cleaning it.

The intermediate pin cylinder 9 is fixedly connected to the work table 3 through a cylinder fixing bracket 10.

[0027] The pneumatic structure includes a pneumatic foot valve 12, which is arranged under the workbench and corresponds to the position of the intermediate pin shaft cylinder 9. The pneumatic foot valve 12 can change its position according to the staff's foot-stepping direction; the intermediate pin shaft cylinder 9 is connected to the pneumatic foot valve 12 through an air source pipeline 11, and one side of the pneumatic foot valve 12 is also connected to a compressed air branch pipe through the air source pipeline 11.

[0028] The working principle of the utility model is as follows:

[0029] See also Figure 1-3 As shown: when using this device, the staff first sticks the molten steel sampler 15 on the placement groove 7, and then steps on the pneumatic foot valve 12, so that the output end of the intermediate pin shaft cylinder 9 drives the matching extrusion groove 8 to move toward the placement groove 7.

[0030] When the paired extrusion groove 8 and the placement groove 7 are adapted and aligned, the staff releases the pneumatic foot valve 12 with their foot, so that the output end of the intermediate pin cylinder 9 is synchronously retracted. At this time, the molten steel sampler 15 can be pulled out of the clamping ring. Then the staff gently shakes the molten steel sampler 15, so that the steel sample is demolded from the molten steel sampler 15 and falls onto the movable cover 13. At the same time, the slag in the molten steel sampler 15 is also scattered on the movable cover 13 under the partition of the side guard plate 6. Next, after the steel sample is completely cooled, it can be labeled and sent for inspection.

[0031] After the steel sample is sent for inspection, the movable cover 13 is opened, so that the slag scattered from the molten steel sampler 15 due to shaking falls into the slag collection box 14.

[0032] The utility model uses the pneumatic principle to make the paired extrusion groove 8 and the placement groove 7 adapt and squeeze the molten steel sampler 15, so as to achieve the technical effect that the steel sample can be demoulded by gently shaking the molten steel sampler 15, thereby reducing the risk of scalding of the staff, and in the process of shaking, the slag can be scattered on the movable cover 13 through the partition of the side guard plate 6.

The utility model has a simple structure and is easy to operate. At the same time, it can reduce the danger of operation and labor intensity, and can be widely used in the molten steel sampling process in the steel industry.
