Abstract
The utility model relates to a combination liquid steel and molten slag sampling device, wherein the lower end of a sleeve is connected with a cup base; a liquid steel cup with a cup plug is embed in the cup base; the upper end of the spoon holder of a slag spoon is connected with an adjusting cup sheathed on the upper part of the sleeve, and the adjusting ring can adjust the position of the slag spoon. Therefore, the sampling device can sample liquid steel and molten slag synchronously, avoid cases and foreign materials in liquid steel sample, accurately represent the relation between liquid steel and molten slag, and provide parameters close to practice for steelmaking process. The sampling device has simple structure, low production cost, low weight and flexibility; the liquid steel cup and the slag spoon can be used repeatedly, to realize two purposes in one device. The device can reduce sampling time, save labor and material resource.
Description
Technical field
The utility model belongs to steel-makingization check field, relates in particular to a kind of combined type sampler that can extract molten steel and slag sample simultaneously.
Background technology
In the STEELMAKING PRODUCTION process, in order accurately to control the composition of steel, must in time understand and grasp the situation of change of snotter in molten steel, slag and the molten steel, therefore take molten steel and slag sample just to become a requisite process means.At present, the mode of sampling mainly contains following three kinds:
1, adopts the iron dipper sampling: utilize the iron spoon of belt length handle, in molten steel, get the molten steel sample earlier and get slag specimen again.
2, adopt the fast sampler sampling: the sampler that the two and half chamber sheets that utilize front end to be provided with port involute, get molten steel sample slag removing sample earlier.
3, common bucket lifting sampler sampling: utilize the oblate iron original mold that is equipped with in the external short paper pipe of long paper pipe, get the molten steel sample earlier and get slag specimen again.
Though above-mentioned sampler has his own strong points, the common defective that exists is: taking molten steel sample and slag sample all is to carry out in two steps, promptly gets the molten steel sample earlier, and then gets the slag sample.Owing to can only take molten steel and slag sample separately, therefore not only waste of manpower, material resources waste time, and complex operation step, have increased sampling personnel's labour intensity.Especially be that molten steel, the slag sample of being got there are differences in time, its correlativity is relatively poor, will directly have influence on precision of analysis.
Summary of the invention
The purpose of this utility model is exactly at the existing problem of above-mentioned sampler, aims to provide a kind ofly can take molten steel sample and slag sample synchronously, makes analysis result more approach the combined type sampler of actual constituent situation.
For this reason, the technical solution taked of the utility model is:
A kind of combined type molten steel, slag sampler are made up of sleeve pipe, cup, molten steel cup, slag spoon, kettleholder and regulating ring; The sleeve pipe lower end is connected with cup, the embedded molten steel cup of cup, and the kettleholder upper end that has the slag spoon is connected on the regulating ring that is set in sleeve pipe top.
Described molten steel cup rim of a cup is provided with the cup plug.
The enforcement the beneficial effects of the utility model are:
The one, realized that molten steel sample and slag sample take simultaneously, make molten steel that sample can a certain moment of accurate response and the relation between the slag, for the process for making adjustment provides more parameter near actual conditions.
The 2nd, adopt the molten steel cup to get the molten steel sample, guaranteed that ghost does not appear in the molten steel sample of getting, both can carry out chemical analysis, can be used for carrying out the snotter check again; And the molten steel cup can also be reused.
The 3rd, the molten steel rim of a cup adopts the shutoff of low-melting glass of plug, avoids that slag enters by slag blanket the time, guarantees the degree of purity of the molten steel sample of getting.
The 4th, whole sampler structure is simple, and is cheap, and configuration is compact, light practicality; The slag spoon is easy for installation, and the position adjustment is flexible, and reusable.
Five is that a device is dual-purpose, and a people once can finish whole sampling process at short notice, and is easy to operate and safe, shortened sample time relatively, reduced labour intensity, saved the man power and material.
Description of drawings
Accompanying drawing is combined type molten steel, slag sampler cut-open view.
Among the figure: 1 is sleeve pipe, and 2 is cup, and 3 is the molten steel cup, and 4 is the cup plug, and 5 is the slag spoon, and 6 is kettleholder, and 7 is regulating ring.
Embodiment
By accompanying drawing as seen, the utility model is made up of sleeve pipe 1, cup 2, molten steel cup 3, cup plug 4, slag spoon 5, kettleholder 6 and regulating ring 7.The cup 2 of a upper end open is welded in the lower end of the sleeve pipe 1 that the employing common steel tube is made, and sets molten steel cup 3 in the cup 2, is plugged with wooden cup plug 4 on the rim of a cup of molten steel cup 3.The lower end of kettleholder 6 has slag spoon 5, and the upper end connects a regulating ring 7, and regulating ring 7 is sleeved on the top of sleeve pipe 1, and can move up and down along sleeve pipe 1, so that adjust the position of slag spoon 5.
During sampling, earlier according to the position of the good slag spoon 5 of thickness adjusted on sleeve pipe 1 of molten slag layer, sampling gun that then will be identical with sleeve pipe 1 internal diameter inserts in the sleeve pipe 1.The operator is inserted into this sampler in the molten steel more fast, and molten steel cup 3 is immersed in the molten steel, and slag spoon 4 then enters in the slag.After wooden cup plug 4 burnt rapidly, molten steel will enter in the molten steel cup 3.After the proposition of this sampler, molten steel sample in the molten steel cup 3 and the slag sample in the slag spoon 5 are taken out and can test.After pouring out the steel stone roller and slag stone roller of cooled and solidified, molten steel cup 3 and slag spoon 5 can also be used for taking a sample next time.
Implement Comparative Examples:
Adopt molten steel and slag composition assay after the utility model and common sampler are taken a sample as follows:
Molten steel and slag composition assay when table 1 adopts the utility model sampling
Molten steel and slag composition assay when table 2 adopts common sampler to take a sample
As seen, be to take a sample at one time though adopt the utility model and common sampler from last tabulation 1 and table 2, it is basic identical therefore to get molten steel component.But, because the time that common sampler is got the slag sample lagged behind 2 minutes than getting the molten steel sample, variation has taken place in therefore obviously visible its slag composition, promptly can not accurate response synchronization molten steel and slag composition between actual relationship, the utility model then can avoid producing this error.
Claims (2)
