Description

Technical Field

[0001] The utility model relates to a TSC sublance probe, belonging to the technical field of sublance probes. Background Art

[0002] The sublance probe technology is the most important means for the automatic steelmaking in converters. Through the sublance measurement system, the smelting accuracy can be improved, the product quality can be enhanced, the smelting time and energy consumption can be saved, etc. At present, the samplers and carbon determination chambers of the existing TSC sublance probes are generally arranged on the side of the paper tube, and the quality of the molten steel entering the samplers and carbon determination chambers is not high, and the success rates of sampling and carbon determination are low. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a TSC sublance probe aiming at the above deficiencies. The sampler is moved from the side of the paper tube to the front end face of the paper tube, and the position of the molten steel inlet is also closer to the front end of the paper tube. The higher the quality of the molten steel entering the sampler and the carbon determination chamber, the higher the success rates of sampling and carbon determination.

[0004] To solve the above technical problems, the technical scheme adopted by the utility model is as follows: a TSC sublance probe, including a paper tube, one end of the paper tube is provided with a sand head, a sampler and a temperature measuring component are embedded at the front end of the sand head, a sample inlet is arranged at the front end of the sampler, and an aluminum protection cap is arranged at the front end of the sample inlet.

[0005] As a further improvement of the above technical scheme:

[0006] A second protection cap is arranged outside the sample inlet.

[0007] The second protection cap includes two layers, the outer layer is a paper layer, and the inner layer is an iron layer.

[0008] A deoxidation component is arranged inside the sampler.

[0009] A carbon determination chamber is arranged at the rear side of the sampler.

[0010] A molten steel inlet is arranged on one side of the paper tube, and the molten steel inlet is communicated with the carbon determination chamber.

[0011] A first protection cap is arranged at the front side of the sand head, and the first protection cap is fixedly connected with the paper tube.

[0012] The utility model adopts the above technical scheme and has the following advantages: in the utility model, the sampler is moved from the side of the paper tube to the front end face of the paper tube, and the position of the molten steel inlet is also closer to the front end of the paper tube. When sampling, the insertion depth of the TSC sublance probe into the molten steel is certain, the positions of the sample inlet of the sampler and the molten steel inlet are closer to the lower part of the molten steel, the molten steel pressure is greater, it is easier for the molten steel to enter, and the probability of the molten steel containing slag in the lower layer is smaller. The higher the quality of the molten steel entering the sampler and the carbon determination chamber, the higher the success rates of sampling and carbon determination.

Embodiment

[0019] As Figure 1 shown, a TSC sublance probe includes a paper tube 1. One end of the paper tube 1 is provided with a sand head 2. A sampler 3 and a temperature measuring component 4 are embedded at the front end of the sand head 2. A first protective cap 5 is provided on the front side of the sand head 2, and the first protective cap 5 is fixedly connected to the paper tube 1.

[0020] The front end of the sampler 3 is provided with a sampling port 6. A deoxidizing component 7 is provided inside the sampler 3 to react with the oxygen in the molten steel to remove the oxygen in the molten steel. An aluminum protective cap 8 is provided at the front end of the sampling port 6. A second protective cap 9 is provided outside the sampling port 6. The second protective cap 9 includes two layers, the outer layer is a paper layer 10 and the inner layer is an iron layer 11. The second protective cap 9 functions during the period from the failure of the first protective cap 5 to the sublance probe reaching the measurement position, preventing the molten steel from entering the sampler 3 before the sublance probe reaches the measurement position and obtaining molten steel containing steel slag.

[0021] A carbon determination chamber 12 is provided at the rear side of the sampler 3, and a molten steel inlet 13 is provided on one side of the paper tube 1. The molten steel inlet 13 is communicated with the carbon determination chamber 12.

[0022] The sampling port 6 of the sampler 3 is moved from the side surface of the paper tube to the front end surface of the paper tube, and the position of the molten steel inlet 13 is also closer to the front end of the paper tube. When sampling, the TSC sublance probe is inserted into the molten steel to a certain depth. The positions of the sampling port 6 and the molten steel inlet 13 of the sampler 3 are both closer to the lower part of the molten steel. The molten steel pressure is greater, and it is easier to introduce molten steel. Moreover, the probability of the molten steel in the lower layer containing steel slag is smaller, and the quality of the molten steel entering the sampler 3 and the carbon determination chamber 12 is higher, and the success rate of sampling and carbon determination is higher.

[0023] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
