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 top blast argon side opening twin-tub sample Steel liquid sampler.
Background technology
In recent years, along with developing rapidly of Steel Industrial, the quality of ferrous materials is had higher requirement.Therefore, in steel smelting procedure to molten steel take a sample, requirement aspect the chemical examination is strict.In order accurately to control the composition of molten steel, harmful element and snotter are big or small, must in time understand and grasp the situation of change of snotter in the molten steel, and function and the shape of Steel liquid sampler are had higher requirement.A lot of steel plant all are the sampler sample examinations with steel spoon or other patterns, the one, adopt the sampling of iron spoon or metal bucket, and 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 the long paper pipe.Although these sampler are easily practical but have common defective: the one, when the iron spoon passes slag blanket the impurity in the slag blanket being brought into affects result of laboratory test in the sampler; The 2nd, thus be that air is easy to molten steel is carried out the accuracy that oxidation affects result of laboratory test when molten steel enters what be full of in the sampler before the sampler.
Summary of the invention
The purpose of this utility model is to provide a kind of top blast argon side opening twin-tub sample Steel liquid sampler, bring into the impurity in the slag blanket in the sampler when solving the steel spoon and passing slag blanket and thereby molten steel enters before the sampler air in the 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 top blast argon side opening twin-tub sample Steel liquid sampler, by paper tube, slag retaining cap, refractory sleeve, the steel pipe sleeve, bottom, argon blowing lance and fire resistive material one, fire resistive material two, fire resistive material three, fire resistive material four form; Sampler inside is by fire resistive material three, refractory sleeve, steel pipe sleeve and bottom sealing form, the first half is refractory sleeve, Lower Half is the steel pipe sleeve, the top is fire resistive material three, having interface in the middle of the fire resistive material three is connected with argon blowing lance, steel pipe sleeve coated outside paper tube, purpose is and the refractory sleeve equal diameter that then one deck paper tube is wrapped up again in steel pipe sleeve and refractory sleeve outside, and steel bushing bobbin and refractory sleeve are closely coupled together, and outside this layer paper tube purpose is in order to allow fire resistive material two wrap up, and point-like all is paper tube among the figure.Steel pipe sleeve and bottom are bonding through glue, and are sealed the bottom by the sticking fire resistive material four of tool; Sampler sidewall middle and upper part has the molten steel inlet port, on the molten steel inlet port slag retaining cap is arranged; Slag retaining cap is bonded on the refractory sleeve through glue; Paper tube inserts fire resistive material two, and is bonding and have viscosity fire resistive material one and seal the upper end through glue.Sampler is sealed by slag retaining cap before sampling and continues to be connected with argon gas; Molten steel bucket sidewall is provided with the molten steel inlet port; The sampling finished product is the twin-tub model.
The enforcement the beneficial effects of the utility model are:
The one, the molten steel inlet port is located at the side of sampler, prevents that effectively slag is involved in molten steel inside, has further improved the precision of sampling steel analysis snotter.
The 2nd, the inside was full of argon gas before sampler was inserted and not entered molten steel below the slag blanket, can not make the molten steel oxidation, can improve chemico-analytic accuracy equally.
The 3rd, slag retaining cap is made by very thin fire resistive material, 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 sampler 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, sample volume is larger, is the twin-tub model, inserts deeplyer, can accurately guarantee the consistance of analysis result and molten steel.
The 6th, easily realize separating of institute's molten steel sample of getting and sampler, be convenient to the Accurate Analysis detection.
The 7th, 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 cut-open view of this kind Novel top Argon side opening twin-tub sample Steel liquid sampler.
Among the figure: 1 is paper tube, and 2 is that fire resistive material one, 3 is that fire resistive material two, 4 is that fire resistive material three, 5 is slag retaining cap, and 6 are fire resistive material sleeve processed, and 7 are steel pipe sleeve processed, and 8 is bottom, and 9 is that fire resistive material four, 10 is argon blowing lance.
