Cov hom crucibles tuaj yeem faib ua peb pawg:

Thawj hom tooj liab smelting crucible, nrog nws tus lej specification;

Hom thib ob yog tooj liab alloy crucibles, uas muaj 100 tus lej tshwj xeeb ncig thiab 100 tus lej ncig;

Peb hom crucible rau steelmaking muaj 100 qhov ntau thiab tsawg

Cov specifications (loj) ntawm lub crucible feem ntau yog sawv cev los ntawm tus lej xaj loj. Thawj crucible muaj peev xwm yaj 1000g ntawm tooj dag, thiab nws qhov hnyav yog 180g. Lub melting tus nqi ntawm lub crucible thaum melting txawv hlau los yog alloys yuav xam tau los ntawm multiplying bulk ntom specification tus naj npawb ntawm crucible los ntawm cov hlau thiab alloy coefficients.

Cov khoom siv raw rau kev tsim cov crucibles tuaj yeem muab faib ua peb hom: thawj, crystalline natural graphite, thib ob, malleable refractory, thiab thib peb, calcined hard kaolin skeleton clinker

Nyob rau hauv xyoo tas los no, cov khoom siv hluav taws xob kub-resistant xws li silicon carbide, alumina, corundum, thiab ferrosilicon tau siv los ua pob txha clinker rau crucibles. Hom clinker no muaj qhov cuam tshuam loj rau kev txhim kho cov khoom zoo ntawm crucible, txhim kho crucible ntom thiab txhua yam muaj zog.

2. Nickel crucibles yog tsim rau melting qauv ntawm NaOH Na2O2, Na2CO3 NaHCO3, thiab alkaline cov kuab tshuaj uas muaj KNO3. Lawv tsis haum rau melting qauv ntawm acidic kuab tshuaj xws li KHSO4 los yog NaHS04, K2S2O7 los yog Na2S2O7, raws li zoo raws li alkaline sulfide fluxes muaj sulfur.

3. Quartz crucible

(1) Quartz crucibles tuaj yeem siv qis dua 1450 degrees Celsius, nrog ob hom: pob tshab thiab opaque. Semi pob tshab quartz crucibles ua los ntawm arc txoj kev yog cov ntaub ntawv tseem ceeb rau kev kos duab loj-inch monocrystalline silicon thiab tsim loj-scale integrated circuits. Niaj hnub no, cov teb chaws tsim nyob rau hauv kev lag luam semiconductor tau hloov me me pob tshab quartz crucibles nrog crucible no. Nws muaj qhov zoo xws li purity siab, muaj zog kub tsis kam, loj loj, siab precision, zoo rwb thaiv tsev, txuag hluav taws xob, thiab ruaj khov zoo.

(2) Tsis tuaj yeem sib cuag nrog HF, yooj yim cuam tshuam nrog caustic soda thiab alkali hlau carbonates ntawm qhov kub thiab txias

(3) Quartz crucibles yog tsim rau melting kuaj nrog K2S2O7 thiab KHSO4 li fluxes, thiab kho cov qauv nrog Na2S207 (thawj qhuav ntawm 212 degrees) raws li fluxes

(4) Quartz yog nkig thiab nquag tawg, yog li ceev faj thaum siv nws

(5) Tsuas yog HF, cov kua qaub zoo tib yam dilute inorganic tuaj yeem siv los ua cov kua dej huv

4. Porcelain crucible

(1) tuaj yeem tiv taus cua sov txog li 1200 degrees

(2) Haum rau cov qauv molten ntawm cov kua qaub xws li K2S207

(3) Nws feem ntau tsis haum rau melting nrog alkaline tshuaj xws li Na0H, Na202, thiab Na2CO3 li fluxes los tiv thaiv corrosion ntawm ceramic crucibles. Ceramic crucibles yuav tsum tsis txhob kov nrog hydrofluoric acid

(4) Porcelain crucibles feem ntau yog ntxuav los ntawm boiling nrog dilute HCl

5. Corundum crucible

(1) Corundum crucible yog tsim los ntawm ntxeem tau molten aluminium oxide, uas yog ruaj khov thiab resistant rau melting

(2) Corundum crucibles yog tsim rau yaj cov qauv uas tsis muaj zog alkaline tshuaj xws li anhydrous Na2C03 li fluxes, tab sis tsis haum rau melting kuaj nrog muaj zog alkaline thiab acidic tshuaj xws li Na202 thiab NaOH li fluxes (xws li K2S 207)
