Mounting device for sub-gun probe with sampling port positioning and method of use thereof

Abstract

The invention relates to the field of converter parts or auxiliary equipment, in particular to a sublance probe installing device with a sampling opening positioning function and a using method thereof. The sublance probe installing device with the sampling opening positioning function comprises a sublance probe (1), a storage box (11), a selecting device (12) and a conveying device (13). The sublance probe installing device with the sampling opening positioning function is characterized in that the sublance probe installing device further comprises a turnover frame (21), a base (22), a driving cylinder (23), a guiding hopper (31), a gripper (32), a bracket (33), a positioning device (4) and a detection switch (5); and a positioning probe (47) is fixed to a supporting frame (42) and rightfaces the outer side face of the sublance probe (1). The using method of the sublance probe installing device with the sampling opening positioning function is characterized by comprising the following steps of a, probe feeding, b, positioning, c, probe inserting, and d, sampling in sequence. According to the sublance probe installing device with the sampling opening positioning function and the using method thereof, control is precise, and the sampling representativeness is high.

Description

technical field [0001] The invention relates to the field of converter parts or auxiliary equipment, in particular to a sub-lance probe installation device with sampling port positioning and a use method thereof. Background technique [0002] In the converter steelmaking process, the auxiliary gun is used to detect the middle and end points of the molten steel, measure the temperature, determine the oxygen and carbon, collect samples and conduct laboratory tests, and combine the smelting model to carry out static / dynamic control of the smelting process, so that the temperature composition of the tapping can reach The ideal goal is an important means to realize automatic steelmaking. The sub-lance probe has a sampling port. When the probe is immersed in molten steel, the molten steel will flow into the sampling port. After the sub-lance detection is completed and the gun is lifted, the molten steel in the sampling port condenses into a solid state, which is the sample. When ...

Problems solved by technology

When the sub-lance is lowered for detection, the oxygen blowing flow rate will be appropriately reduced, but the closer to the center line of the converter, that is, the more violent the molten steel churning at the position of the oxygen lance, the stronger the various physical and chemical reactions, and the higher the oxygen content. The sampling port is located at The cylindrical surface of the probe, the angle of the sampling port toward the center line of the converter after each probe is installed is random, the position from the center line of the converter is different, and the sampling is uncertain. The sample obtained when the sampling port is close to the center of the converter contains oxygen The amount of liquid steel is higher, and the composition of molten steel is also different from the place far away from the oxygen lance, which weakens the representativeness of the sample obtained by the probe, which is not conducive to the composition control of steelmaking
