Description

Technical Field

[0001] The utility model relates to the technical field of iron and steel metallurgy, in particular to a device for forming a standard control sample for direct-reading spectral analysis. Background Art

[0002] The blast furnace smelting of Panzhihua Steel Xichang Steel Vanadium mainly uses vanadium-titanium magnetite. The molten steel and hot metal contain elements such as vanadium and titanium. There are few commercially available direct-reading spectral calibration samples containing vanadium and titanium, and it is impossible to comprehensively cover the direct-reading spectral standard control samples of vanadium-titanium-containing molten steel and hot metal in Xichang Steel Vanadium. At the same time, compared with ordinary iron ore smelting blast furnaces, the furnace temperature is lower, the fluidity of the hot metal is slow, and the cooling speed is extremely fast. Ordinary forming devices cannot take and form regular, uniform and easy-to-artificially-excite vanadium-titanium spectral control samples.

[0003] In order to improve the detection accuracy of vanadium-titanium-containing steel samples, it is necessary to specially make a sampling and forming device for steel samples containing vanadium-titanium components suitable for Xichang Steel Vanadium Company, so that the sample excitation is convenient and the "white mouth" effect is good, and it can be used for the quality control and value transfer of steel samples containing vanadium-titanium elements in Xichang Steel Vanadium.

[0004] At present, commercially available standard samples are mainly used for the quality control and value transfer of direct-reading spectra, but the drift correction effect for samples containing vanadium and titanium elements is not ideal, and it is impossible to accurately monitor the detection accuracy of samples.

[0016] In order to more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the following will briefly introduce the drawings required for use in the description of the embodiments or the prior art. Obviously, the following-described drawings are some embodiments of this utility model. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0017] See the attached Figures 1-3 , a device for forming a standard control sample for direct-reading spectral analysis proposed by this utility model includes a cylindrical main body 1. Among them, an upper region inside the cylindrical main body 1 is coaxially provided with a sample injection port 2; a middle and lower region inside the cylindrical main body 1 is coaxially provided with a sample forming area 3; a sample injection channel 4 is coaxially provided between the sample injection port 2 and the sample forming area 3, and the upper and lower ends of the sample injection channel 4 are respectively coaxially communicated with the sample injection port 2 and the sample forming area 3.

[0018] Both the sample injection port 2 and the sample forming area 3 are cylindrical cavities, and the diameter of the sample forming area 3 is larger than that of the sample injection port 2; the sample injection channel 4 is also a cylindrical cavity. In this embodiment, the diameter of the sample injection port 2 is 25 cm and the height is 10 cm; the diameter of the sample forming area 3 is 33 cm and the height is 53 cm; the diameter of the sample injection channel 4 is 9 cm and the height is 18 cm.

[0019] In this embodiment, the material of the cylindrical main body 1 is low-alloy high-strength structural steel, which has good cold stamping properties.

[0020] The working principle of the utility model is as follows: Place the device directly in the sampling area, with the sample injection port 2 facing upward and the sample forming area 3 facing downward. Inject the molten steel sample through the sample injection port 2. The sample quickly flows into the interior of the sample forming area through the sample inlet channel 4 and solidifies. The sample is first cooled through the sample inlet channel 4 and then quickly cooled and formed for the second time inside the sample forming area 3. After the sample is cooled and formed, gently tap the cylindrical main body 1 from above, and the sample will automatically fall off, and the spectral analysis standard control sample is then prepared.
