Abstract
The utility model relates to a static-pressure cylinder-type sampler for molten steel. The utility model is mainly characterized in that a thin paper tube is sheathed in a thick paper tube, the left end of the thin paper tube is connected with a refractory supporting pad whose left end is connected with a refractory sampling mold, an opening at the left end of the refractory sampling mold is connected with a quartz tube whose outside is sheathed with a small iron tube, the outside of the small iron tube is connected with a paper pad and refractory cements, the left end of the small iron tube is sheathed with a small iron cap, and the left end of the thick paper tube is sheathed with a big iron cap. The utility model has the main application that the sampler breaches a slag blanket to take out cylindrical steel samples in the molten steel, and the molten steel is sampled rapidly, safely, accurately and easily.
Description
The utility model relates to a kind of molten steel sampler, especially a kind of static pressure column type Steel liquid sampler.
In steel smelting procedure, to molten steel sample examination aspect, most steelworkss also all are with the chemical examination of steel dipper sampling at present.After molten steel was come out of the stove, with the dipper sampling chemical examination, the steel spoon will be taken a sample in molten steel by the slag layer when this method was got molten steel in stokehold or steel ladle, and this just brings slag or other impurity into sometimes unavoidably, therefore, and also with secondary sample.Need behind the molten steel to go out casting censorship sample with the steel bale-out, in casting, come in contact, produce secondary oxidation with air, secondary nitrogenize, carbonization, this just influences the accuracy of molten steel chemical examination.With the sampling repeatedly owing to slag inclusion sometimes when casting of steel dipper sampling, this has just increased the duration of heat, and the operating personnel's accident of burning easily takes place again.
The purpose of this utility model provides and a kind ofly can make molten steel sampling break through slag blanket to take a sample in molten steel, and make the censorship sample in sampling operation from the molten steel liquid state to solid-state, in sampler, once finish.Make the molten steel analysis data accurate, be the smelting iron and steel operating personnel, quick, easy, safe and reliable instrument is provided on sampling method.
The utility model is achieved like this, thin paper tube is with the rag paper pipe outward, connect fire-resistant pad at thin paper tube left end, fire-resistant pad has vent port, what be connected with fire-resistant pad is fire-resistant original mold, fire-resistant original mold left end opening part is connected with high temperature resistant quartz ampoule right-hand member, high temperature resistant quartz ampoule is with iron pipe outside the left side, in fire-resistant original mold left part and iron pipe junction paper washer is arranged, the paper washer left end is connected with fire cement, the iron pipe left end connects small iron cap, is with big chapeau de fer at rag paper pipe left end, and big chapeau de fer has through hole.
During use, will insert in the thin paper tube of Steel liquid sampler and the thin identical iron pipe of paper tube internal diameter, the operator inserts sampler in the molten steel with iron pipe, and the degree of depth is to be as the criterion by slag blanket.At this moment molten steel dissolves big chapeau de fer, and small iron cap takes out sampler because the static pressure molten steel of molten steel flows in the fire-resistant original mold from quartz ampoule again from molten steel, break paper tube and get tapping sample.
The utility model compared with prior art has following advantage:
1, safe and reliable, simple to operate, data are accurate
2, cost is low, and is economical and practical, easily promotes
Concrete structure of the present utility model and embodiment are provided by the following drawings
Figure one is that the utility model general structure is cutd open and shown synoptic diagram
Below in conjunction with accompanying drawing concrete structure of the present utility model and embodiment are described in further detail.
Shown in accompanying drawing one, rag paper pipe 10 is enclosed within on the thin paper tube 11, connect fire-resistant pad 7 at thin paper tube 11 left ends, has vent port 12 on the fire-resistant pad, connect fire-resistant original mold 6 at fire-resistant pad 7 left ends, fire-resistant original mold 6 left end opening parts connect quartz ampoule 4, quartz ampoule 4 outsides are with iron pipe 3, in iron pipe 3 and fire-resistant original mold 6 junctions, be with paper washer 5, paper washer 5 left ends are equipped with fire cement 9, are with the left end that small iron cap 2, big chapeau de fer 1 are enclosed within rag paper pipe 10 at iron pipe 3 left ends, have through hole 8 on big chapeau de fer top.
When sampling, in the thin paper tube of sampler, insert and the thin identical iron pipe of paper tube internal diameter, sampler is passed through to insert in the molten steel behind the slag, molten steel melts big chapeau de fer, small iron cap and flows in the fire-resistant original mold from quartz ampoule, again sampler is taken out from molten steel, break paper tube, get tapping sample.
