Graphite crucibleSilicon carbide graphite crucibleyog ib lub thawv ua los ntawm graphite raws li raw khoom, yog li nws muaj zoo heev kub kuj thiab yuav siv tau nyob rau hauv industrial hlau smelting los yog casting. Piv txwv li, hauv lub neej niaj hnub, koj tuaj yeem nkag siab tias feem ntau muaj cov tub lag luam nyob rau hauv cov cheeb tsam nyob deb nroog uas kho cov lauj kaub txhuas lossis cov lauj kaub txhuas. Cov cuab yeej lawv siv yog crucibles. Cov nplooj ntawv txhuas yog muab tso rau hauv lub crucible thiab rhuab nrog hluav taws kom txog thaum lawv yaj mus rau hauv cov dej txhuas, ncuav nws rov qab mus rau qhov tawg ntawm lub lauj kaub, txias nws, thiab tom qab ntawd nws tuaj yeem siv tau. Txawm li cas los xij, graphite crucibles thiab silicon carbide crucibles yog siv hauv kev lag luam. Ntawm lawv, graphite crucibles muaj thermal conductivity zoo, tab sis lawv nquag oxidation thiab muaj kev puas tsuaj loj. Silicon carbide graphite crucibles muaj qhov ntim loj dua thiab siv lub neej ntev dua li graphite crucibles. Peb tau tshwj xeeb hauv kev muag khoom thiab kev tsim khoom ntawm crucibles rau 40 xyoo. Cov graphite crucibles peb tsim yog dav haum rau smelting kub, nyiaj, tooj liab, hlau, txhuas, zinc, thiab tin, raws li zoo raws li rau ntau yam smelting thiab cua sov txoj kev xws li coke, roj rauv, natural gas, hluav taws xob rauv, thiab lwm yam. graphite crucibles peb tsim tau raug qhuas los ntawm cov neeg siv khoom tshiab thiab qub rau lawv cov khoom zoo thiab kev ua haujlwm ruaj khov. Peb kuj qhia txog cov txheej txheem siab tshaj plaws crucible - isostatic siab crucible forming method - raws li kev lag luam thiab cov neeg siv khoom xav tau, Thiab kev soj ntsuam nruj nruj, cov silicon carbide crucible tsim los ntawm cov thev naus laus zis no muaj cov yam ntxwv ntawm qhov ntim siab, kub tsis kam, ceev. thermal conductivity, acid thiab alkali corrosion kuj, siab kub zog, thiab siab oxidation kuj. Nws lub neej kev pabcuam yog 3-5 npaug ntawm graphite crucibles. Nyob rau tib lub sijhawm, nws txuag roj thiab txo kev siv zog rau cov neeg ua haujlwm. Tus nqi ntawm lub zog-txuag isostatic siab crucibles thiab lub zog-txuag isostatic siab crucibles ua rau cov khoom no dav siv rau smelting ntawm non-ferrous hlau.
Graphite crucibles tuaj yeem siv rau hauv ntau lub qhov cub, xws li hluav taws xob rauv, nruab nrab zaus furnaces, gas furnaces, kilns, thiab lwm yam, rau smelting kub, nyiaj, tooj liab, hlau, txhuas, zinc, tin, thiab alloys. Txoj kev teeb tsa raug rau graphite crucible thiab silicon carbide crucible
1. Lub hauv paus ntawm graphite crucible yuav tsum muaj tib lub kab uas hla los yog loj dua li hauv qab ntawm lub crucible, thiab qhov siab ntawm lub crucible platform yuav tsum siab tshaj lub nozzle los tiv thaiv hluav taws los ntawm kev txau mus rau lub crucible.
2. Thaum siv cov pob zeb refractory li cov ntxhuav crucible, yuav tsum siv cov cib refractory, uas yog tiaj tus thiab tsis khoov. Tsis txhob siv cov ntaub ntawv cib ib nrab lossis tsis sib xws. Nws yog qhov zoo dua los siv cov graphite crucible tuaj txawv teb chaws.
3. Lub rooj crucible yuav tsum tau muab tso rau ntawm qhov chaw nruab nrab ntawm melting thiab melting, nrog coke hmoov, straw tshauv, los yog refractory paj rwb ua lub ncoo kom tsis txhob adhesion ntawm crucible thiab crucible rooj. Tom qab muab lub crucible, nws yuav tsum yog theem.
4. Qhov luaj li cas ntawm lub crucible thiab lub qhov cub lub cev yuav tsum sib phim, thiab qhov kev ncua deb ntawm lub crucible thiab melting phab ntsa yuav tsum tsim nyog, tsawg kawg yog 40mm los yog ntau tshaj.
Thaum thauj cov beaked crucible rau hauv lub qhov cub, qhov sib txawv ntawm kwv yees li 30-50MM yuav tsum tau tshwj tseg nyob nruab nrab ntawm lub hauv qab ntawm crucible nozzle thiab cov cib refractory, thiab tsis muaj dab tsi yuav tsum tau muab tso rau hauv qab. Lub nozzle thiab lub qhov cub phab ntsa yuav tsum smoothed nrog refractory paj rwb. Cov phab ntsa ntawm lub cub tawg yuav tsum tau kho cov cib refractory thiab cov crucible yuav tsum tau padded nrog corrugated cardboard nrog ib tug tuab ntawm txog 3 hli raws li lub thermal expansion qhov chaw tom qab cua sov.
Kev tsim cov thev naus laus zis ntawm graphite crucibles feem ntau yog cuam tshuam nrog cov qauv, cov khoom siv raw, cov cuab yeej tsim khoom, thiab thev naus laus zis. Nyob rau hauv cov nqe lus ntawm raw khoom xaiv, peb tsuas yog siv refractory av nplaum, aggregates, ntuj graphite, thiab lwm yam. Raws li qhov sib txawv zog ntawm txhua crucible, cov khoom xyaw thiab cov qauv peb xaiv kuj txawv, feem ntau yog reflected nyob rau hauv qhov sib txawv proportions ntawm ntau yam raw khoom. Cov txheej txheem yog los ntawm compression molding, teb molding, thiab tes molding, uas yog graphite molding. Tom qab ua cov molding, nws yog ib qho tseem ceeb kom nco ntsoov kom qhuav nws. Tom qab kuaj xyuas, nws tsim nyog, thiab cov khoom tsim nyog tuaj yeem glazed
