Description
Technical field
The utility model relates to gets a kind of device of oxygen nitrogen sample in the molten steel, it is applicable to producing of ladle in refining, the casting process, the interior molten steel oxygen nitrogen sample of middle bag.
Background technology
Oxygen in the steel, nitrogen snotter are very big to the performance impact of steel, under many situations, gaseous impurities in the steel surpasses finite concentration can cause that steel is transformed to fragility by plasticity, thereby generation deleterious effect, but sometimes contain an amount of nitrogen in the steel, can play promotion grain refinement, the hardness that improves steel and the effect of intensity again.Therefore oxygen, nitrogen content have important directive significance to steel-making in the accurate analysis steel.
At present, the scene is carried out the oxygen nitrogen analysis and is achieved in that at first and obtains sample with sampler, the sampler system of closing after by two iron plate pressing molds forms, the front end of mould is provided with the melt introducing port, with the supporting installation of introducing port be the two ends quartz ampoules that communicate, whole sampler is wrapped up in high temperature resistant paper bag.Head is installed the slag retaining cap that a flake aluminum is made.Then, this sampler is inserted in the molten steel, the static pressure extraction sample by molten steel knocks out sample on ground after the water-cooled.At last, cut the interior specimen-specific of quartz ampoule and carry out oxygen, nitrogen analysis, all the other samples are done other constituent analysis.
Said sample is to lean on the static pressure of molten steel to obtain, molten steel enters into mould and contacts with gas in the mould, sample top layer oxygen nitrogen content will certainly be influenced by oxygen in the air, nitrogen, in addition, in this sampler, compensate when molten steel can shrink molten steel solidification in the mould in the quartz ampoule, therefore the quartz ampoule sample that cuts can present hollow state.Under influence aspect above-mentioned two, cause oxygen, nitrogen content test back data inaccurate.
Through the disclosed patent of China is retrieved, finding two similar patents one is patent " molten steel soak-in type vacuum fixed hydrogen high-speed sampler " in 1988, because also diffusion easily under the hydrogen normal temperature, in order accurately to analyze hydrogen in the steel, this sampler is provided with inside and outside two-layer steel sleeve pipe and collects molten steel, inner sleeve sample analysis remaining hydrogen content, outer tube sample analysis diffusible hydrogen content.Because it is slower that oxygen, nitrogen spread in steel, this sampler is comparatively complicated for getting oxygen nitrogen spline structure, and in addition, elements such as hydrogen, oxygen, nitrogen also can spread in the steel sleeve pipe, and are unfavorable to analytical element content.Two is utility models " a kind of vacuum type molten steel sampler " in 1992, its vacuum system is to be controlled by the cylinder that has piston, in actual production, consider the distance between operating platform and the molten steel jar, the cylinder control position of this sampler is sizable, it is very complicated to operate, so be not suitable for the sampling of large-scale ladle.
From the retrieval of Wei Pu information network two pieces of articles that relate to vacuum steel water sampler aspect are arranged, one is that 2007 " bao steel technology " delivered in " sample to clean steel ultimate analysis influence simple analysis " paper and mentioned the glass tube with vacuum sampler, and it is applied to decide producing of hydrogen sample equally.Also introduced a kind of total oxygen sampler in the literary composition, the band argon shield can be avoided the influence of air oxidation and slag in sampling process, but blowing argon gas always in the sampling process causes the inside and outside positive pressure differential that produces of sampler, is difficult to get sample.The 2nd, " with the hydrogen in the iron sleeve pipe sampler mensuration of the vacuum molten steel " that nineteen ninety " Baosteel information " delivers, it also is applied to decide producing of hydrogen sample.
Present in sum sampler does not also satisfy the sampling requirement to nitrogen oxygen.
Summary of the invention
The purpose of this utility model overcomes above-mentioned technical deficiency, and a kind of molten steel soak-in type vacuum fixed oxygen nitrogen fast sampler is provided, and it is simple in structure, easy to operate, institute's sample thief is even, fine and close, and can keep original crystal structure of sample and composition, improves accuracy of analysis.
The utility model is a kind of device of steel water oxygen-taking nitrogen sample.Its ultimate principle is with vacuumizing after high temperature resistant and the quartz ampoule sealing of enbrittling when the low temperature, when producing sample, is not the static pressure by molten steel, but by in the vacuum tube and the pressure differential that forms between the molten steel and obtain sample.
The purpose of this utility model is achieved in that and comprises sampler, and skimming device is characterized in that, sampler adds the sealing device by the quartz ampoule front and constitutes, and vacuumizes then, and sampler is fixed in the paper web, and front end is installed skimming device.
Concrete structure of the present utility model has, and quartz ampoule is placed with paper web is concentric, and makes the quartz ampoule front end expose paper web.
The related quartz ampoule internal diameter of the utility model is φ 6～φ 10mm, wall thickness 1～2mm, and length is 80～100mm.
The internal diameter of the paper web that the utility model is related is φ 30～φ 50mm, wall thickness 10～15mm, and length is 800～1000mm.
Advantage of the present utility model: simple in structure, easy to operate, the vacuum sampling, sample is even, fine and close.Need not water-cooled after the sampling, can keep its original crystal structure and composition, improve accuracy of analysis, be convenient to guiding operation.
