Daim ntawv thov:

1 、 Cov roj hlawv ntawv tshiab

2 、 Tshaj Tawm Kev Hloov Tshav Kub

Cov pob hluav taws xob tshiab tsim nyog rau cov pa roj thiab cov roj nkev roj cua sov kev lag luam ntawm kev tsim hluav taws xob tshiab tau raug xaiv, tshwj xeeb tshaj yog rau cov khoom siv hluav taws xob cua kub ntawm cov hlau kev lag luam kev lag luam, kuj tseem siv loj hauv forging cog cov hluav taws xob trolley hluav taws xob, cov tshuab hluav taws xob rau cov tshuab hluav taws xob, cov tshuab hluav taws xob ntxig hluav taws xob ua hluav taws xob rov ua dua tshiab.

Properties:

Spherical pob ntawm alpha-alumina (corundum) yog tsim los ntawm sintering pob-ua hom calcined alumina ntawm qhov kub tsuas yog nyob rau hauv 3704 ° F (2040 ° C) fusion point ntawm txhuas oxide. Ob hom kev tsim cov txheej txheem: dov thiab nias.

Lub npov cia pob kub ntawm cov pob txha tsis yeem alumina yog cov khoom siv tau zoo refractory nrog cov yam ntxwv zoo kawg ntawm kev txo qis ntawm cov kab rov ua dua, siab muag kub nyob hauv siab kub load, corrosion tsis kam, siab zog, loj tshav kub cia thiab tso tawm, zoo thermal poob siab ruaj khov, zoo thermal conductivity, me me thermal expansion coefficient thiab hais txog. Raws li cov pa roj (tawg cua sov ua kom sov, hloov pauv hloov) thiab huab cua ua pa rau ob leeg ua ntej (roj, muaj qhov siab calorific nqi roj txuas ntxiv, xws li muaj cua sov cia hom), tuaj yeem ua rau cov cua sov ua kom muaj pa taws tsawg dua 20-50%, pa pa kub pa taws poob rau qis dua 150 degrees, yields los ntawm 15-20%, billet cua sov lub sijhawm luv luv 50%, oxidation hlawv poob txo 30-50% ntawm kev tiv thaiv ib puag ncig thiab txuag hluav taws xob nyhuv.Hauv cov txheej txheem ua haujlwm, alumina pob hauv lub tshav kub cia tank faib cov cua ntws mus rau hauv feem ntau me me txaus strands, thiab cov cua ntws ua lub zog ntawm lub nroo thaum nws ntws hauv cov cua sov kev sib tw hauv lub cev, uas tuaj yeem nqus tau cov cua kub nyob rau saum npoo ntawm lub tshav kub conduction lub cev, yog li cov tshuab hluav taws xob hloov tshiab tuaj yeem hloov tau feem ntau thiab sai sai.Tom qab cov pa roj kub kub dhau los ntawm tus tsim hluav taws xob, qhov kub tau nce mus txog tsuas yog li 100 ℃ qis dua qhov kub flue roj, thiab qhov ntsuas kub kub tshaj 90%.

Qhov zoo:

Corundum alumina pob yog ua los ntawm kev lag luam alumina ua cov khoom siv tseem ceeb. Nws muaj cov yam ntxwv ntawm qis qis qis, siab kub load softening ntsuas kub, corrosion tsis kam, siab zog, loj cia kub thiab tawm, zoo thermal poob siab ruaj khov, zoo thermal conductivity thiab cov lej me ntawm thermal nthuav dav.

Zog:

Dawb crystalline gravel lossis pob. Ua raws li qhov xav tau, qhov ntau thiab tsawg pob tau tsim los ntawm 1/8 txog 2 nti (kam rau ua ± 6% hli)
