Abstract
The utility model discloses a high temperature-resistant, strong corrosion-resistant double-layered crucible, which comprises a crucible A and a crucible B, the crucible A serves as a primary reactor, and the crucible B serves as a secondary protective reactor. Both the crucible A and the crucible B are made of high-grade refractory material, and the material of the crucible depends on an experimental reagent corrosion mechanism. The crucible A is an ordinary crucible, and three angled supports, on which the crucible A is placed, are arranged in the crucible B, and can keep a proper distance between the outer wall of the crucible A and the inner wall of the crucible B. During an experiment, if the crucible A is corroded out by reagent under high temperature and strong corrosion, the experiment can go on in the crucible B. If the crucible A is not corroded out, the crucible B can be repetitively used.
Description
Technical field
The present invention relates to a kind of double crucible of high temperature resistant, deep-etching.
Technical background
At present, crucible is used comparatively extensive in field of metallurgy, be mainly the individual layer crucible.If under high temperature, deep-etching situation, the individual layer crucible may be unable to born erosion and be penetrated, and this phenomenon happens occasionally in the metallurgical melt test.In order to strengthen the anti-erosion performance of crucible, select anti-material according to the erosion mechanism of metallurgical melt, can slow down the corrosion of crucible thus, but under harsh experimental condition, crucible also might be unable to bear erosion.So at this kind phenomenon, the present invention arises at the historic moment.
Summary of the invention
The double crucible that the purpose of this invention is to provide a kind of high temperature resistant, deep-etching.
The present invention adopts following technical scheme to realize its purpose, a kind of double crucible, and it comprises two crucibles of A, B, and the A crucible is as primary reactor, and the B crucible is the second class protection reactor.Crucible material is decided by the test reagent erosion mechanism, all chooses the senior processing and fabricating of anti-the material and forms.The A crucible is common crucible, and B crucible inside is provided with three angle holders, is used to support A crucible and control A crucible outer wall and B crucible inwall in suitable distance.
It is extremely convenient that the present invention uses, and reagent is inserted in the A crucible, the A crucible put into the B crucible again and can be inserted experimental enviroment and use.
The novel invention crucible of this kind can use in high-intensity experimental enviroment.Three angle holders of B crucible are used to place the A crucible, prevent that simultaneously the A crucible from contacting with the B crucible.Though A, B crucible material are decided by the test reagent erosion mechanism, promptly corrosion resistance is strong, and very under the exacting terms, the A crucible can be etched and penetrate condition.Unique distinction of the present invention is: when the A crucible be etched penetrate after, test can be continued in the B crucible, and can destruction test equipment.In addition, if the A crucible is not etched and penetrates, then the B crucible can repeatedly use.

Figure 1B is the A-A direction cut-away view of A crucible shown in Figure 1;
Fig. 2 is the structure chart of B crucible;
Fig. 2 B is the A-A direction cut-away view of A crucible shown in Figure 2;

The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing.
High temperature resistant, the double crucible of being able to bear strong corrosion of the present invention comprises A, B crucible, and the A crucible is as primary reactor, and the B crucible is the second class protection reactor.During test, reagent is inserted the A crucible, and the A crucible is put into the B crucible.If the A crucible is corroded penetrate, then test in the B crucible and continued, built-in three angles holder of B crucible is used to place the A crucible, and its angle holder can be controlled A crucible outer wall in addition and B crucible inwall distance is suitable., the A crucible is zigzag with the part that the B crucible is contacted, in case high temperature melting causes A, B crucible to fuse than large tracts of land, is convenient to separate A, B crucible, does not penetrate if the A crucible is corroded in test, and then the B crucible can repeatedly use.
Embodiment 1
Just brave bridge iron ore (TFe=60.06%, FeO (%)=28.22, SiO2 (%)=2.96, Al2O3 (%)=3.98, MgO (%)=2.44, CaO (%)=0.58, TiO2 (%)=6.47, S (%)=0.12, P (%)=0.01), flux and coal (C (%)=76.43, ash content (%)=15.29, fugitive constituent (%)=7.78, CaO (%)=1.59, SiO2 (%)=7.80, S (%)=0.35, powder fragmentation P (%)=0.050) (≤30mm), be 1.1 according to basicity, join carbon ratio C/O and be 1.1 technological parameter proportioning mixing, insert in the A corundum crucible, be inserted in again in the B corundum crucible, will test A, the B crucible is put into resistance furnace, temperature adjustment to 1600 ℃, under the condition of oxygen-enriched top blowing, take off titanium, constant temperature 30 minutes after the off-test, finds that the A crucible does not have corrosion to penetrate, then broken A crucible, sampling detects.The B crucible is intact, does not then have to corrode under the situation about penetrating at the A crucible, and the B crucible can repeatedly use.
Embodiment 2
Above-mentioned raw materials is identical, test temperature, and basicity is identical, constant temperature 60 minutes, after the off-test, it is penetrating to find that the A crucible has been etched, and molten iron and slag are all fallen in the B crucible, then broken B crucible, sampling detects.The A crucible penetrates, and the B crucible continues melting as reactor, so in this test, with broken B crucible, detect the slag ferrous components, the B crucible is being disposable use in such cases.
Claims (3)
1. double crucible; comprise A, B crucible; the A crucible is as primary reactor; the B crucible is the second class protection reactor; built-in three angles holder of B crucible; be used to place the A crucible, its angle holder can be controlled A crucible outer wall in addition and B crucible inwall distance is suitable, and the A crucible is zigzag with the part that the B crucible is contacted.
2. double crucible according to claim 1 is characterized in that: reagent is inserted the A crucible, and the A crucible is put into the B crucible.
