Abstract
The utility model belongs to the field of steel metallurgy, relates to a steel sampler and analyzer, and in particular relates to a vacuumizing side-opened high-purity molten steel sampler. The sampler comprises a sampling chamber 1, a slag stopping cap 2 and a movable bottom cover 3, wherein the movable bottom cover 3 is connected with the lower end of the sampling chamber 1; a molten steel inlet is formed in the side wall of the sampling chamber; and the slag stopping cap 2 is arranged on the sampling chamber. The sampler is characterized in that the sampler is subjected to vacuumizing operation before being inserted into the molten steel, the molten steel inlet is formed in the side wall of a molten steel bucket, and the molten steel inlet is stopped by the slag stopping cap 2 after the vacuumizing operation. The sampler can be used for effectively preventing slag entering and secondary oxidation of the molten steel, and ensuring the purity of a steel sample.
Description
Technical field
The utility model belongs to the Ferrous Metallurgy field, relates to steel sample sample analysis utensil, refers to particularly a kind of novel side opening high-purity molten steel sampler that vacuumizes.
Background technology
Along with the fast development of steel industry, more and more higher to the requirement of ferrous materials.Therefore, the requirement aspect in steel smelting procedure, molten steel being chemically examined is strict.In order accurately to control the composition of molten steel, must in time understand and grasp the situation of change of snotter in molten steel, function and the shape of Steel liquid sampler are had higher requirement.A lot of steel plant are all the sampler sample examinations with steel spoon or other patterns, but have certain shortcoming.The one, adopt the sampling of iron spoon or metal bucket, utilize and take a sample in molten steel with the iron spoon of long handle; The 2nd, adopt the fast sampler sampling, the sampler that the two and half chamber sheets that utilize front end to be provided with port involute; The 3rd, common bucket lifting sampler sampling utilizes the oblate property iron original mold that is equipped with in long paper pipe.Although these sampler are easily practical but have common defective: the one, when the steel spoon passes slag blanket, the impurity in slag blanket being brought into affects result of laboratory test in sampler; The 2nd, thus be that air is easy to that molten steel is carried out oxidation and affects result of laboratory test when molten steel enters what be full of in sampler before sampler.
Summary of the invention
The purpose of this utility model is to provide a kind of side opening high-purity molten steel sampler that vacuumizes, bring into the impurity in slag blanket in sampler when solving the steel spoon and passing slag blanket and thereby molten steel enters before sampler the air in sampler and easily molten steel carried out oxidation and affect the result of laboratory test problem, aim to provide a kind of analysis result that can make closer to the sampler of actual constituent situation.
To achieve these goals, the technical solution of the utility model is:
A kind of side opening high-purity molten steel sampler that vacuumizes is comprised of sampling chamber, slag retaining cap and movable bottom.Sampling chamber lower end is connected with movable bottom, the molten steel inlet port that has on the sampling chamber sidewall after slag retaining cap gets lodged in and vacuumizes.
Have the molten steel inlet port on described sampling chamber sidewall and have slag retaining cap to block.
Described sampler first vacuumizes before inserting sampling, then blocks molten steel inlet port on sampling chamber upper side wall with slag retaining cap.
The enforcement the beneficial effects of the utility model are:
The one, the molten steel inlet port is located on the side of sampling chamber, be unfavorable for that slag can not be involved in molten steel inside, has further improved the precision that sampling steel is analyzed snotter.
The 2nd, before sampler is inserted and not entered molten steel below slag blanket, the inside vacuumizes, and can not make the molten steel oxidation, can improve chemico-analytic accuracy equally.
The 3rd, slag retaining cap is made by tagger, and wall prevents that by slag blanket the time slag from entering when inserting, and guarantees the degree of purity of the steel sample of getting.
The 4th, molten steel is full of the sampling chamber when extracting rapidly later on, and the upper opening portion molten steel flows out, and can prevent effectively that also slag is involved in molten steel inside.
The 5th, whole sampler structure is simple, and is cheap, and configuration is compact, light practicality.
Description of drawings
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Fig. 1: the utility model vacuumizes the cut-open view of side opening high-purity molten steel sampler.
In figure: 1 is the sampling chamber, and 2 is slag retaining cap, and 3 is movable bottom.
Embodiment
Referring to accompanying drawing 1, the utility model is by sampling chamber 1, slag retaining cap 2, and movable bottom 3 forms.The lower end of the cover sampling chamber 1 that the employing steel pipe is made is connected with movable bottom 3, on sampling chamber 3 sidewall openings, slag retaining cap 2 is arranged.
Before sampler is inserted sampling, first vacuumize, then block molten steel inlet port on chamber 1 upper side wall of taking a sample with slag retaining cap 2.Sampler is welded on sampling gun.The operator again with the sampler quick insertion in molten steel, when sampling chamber 1 is immersed in the position of wanting below slag blanket to take a sample, through molten steel after 1～2s, slag retaining cap 2 is melted, owing to being vacuum condition in the molten steel bucket, molten steel enters in sampling chamber 1, after continuing 2～3s, when molten steel is full of sampling chamber 1, rapidly sampler is proposed, with hammer, movable bottom 3 is knocked out after solidification of molten steel, then the molten steel sample in sampling chamber 1 is taken out and can test.Pour out the steel of cooled and solidified and cut or polish jade with an emery wheel further chemical analysis and inclusion analysis etc.
