Description

Technical Field

[0001] This utility model belongs to the field of blast furnace sampling devices, and more specifically, relates to a blast furnace molten iron sampling device. Background Technology

[0002] In the steel production process, the blast furnace is a crucial component. By taking molten iron samples in front of the furnace for testing and analysis, the composition of the molten iron at the time of sampling can be clearly determined. Based on a comprehensive analysis of the molten iron composition, adjustments can be made to the blast furnace conditions. Therefore, taking molten iron samples in front of the furnace is one of the most important tasks.

[0003] Currently, when taking samples of molten iron in our plant's blast furnace system, the commonly used tool is the sampling spoon (such as the one used by the furnace operator for casting molten iron) Figure 1 As shown), after scooping molten iron from the trough with a sampling spoon, pour it into a mold (as shown). Figure 2 As shown in the diagram, a piece of iron about 15cm long is then manually inserted, bearing the batch number of the molten iron. This process involves numerous steps and lasts a long time. Because the temperature of the molten iron can reach over 1400 degrees Celsius, and the ambient temperature in front of the blast furnace is high, the labor intensity for furnace workers is high, and accidents such as burns and heatstroke are likely to occur.
