Siv thiab ceev faj ntawm lub thawv hom tsis kam rauv / muffle rauv

Siv thiab ceev faj ntawm lub thawv hom tsis kam rauv / muffle rauv. Lub npe nrov rau muffle furnaces nyob rau hauv Suav teb yog raws li nram no: hluav taws xob furnaces, resistance furnaces, Maofu furnaces, los yog lub thawv hom kuj furnaces. High kub muffle rauv yog ib tug universal cua sov khoom. Nws tuaj yeem muab faib ua lub thawv rauv, tub rauv, lub qhov cub tawg. Muaj cov tshuab hluav taws xob hauv tsev thiab cov khoom siv hluav taws xob txawv teb chaws (American muffle furnaces, German muffle furnaces, thiab lwm yam). Lub muffle furnace yog hom kev ua haujlwm raws sijhawm, siv los ntawm cov chaw soj nstuam, kev lag luam thiab kev lag luam mining, thiab cov chaw tshawb fawb tshawb fawb txog kev tshawb fawb thiab kev txiav txim siab, nrog rau kev kho cua sov xws li quenching, annealing, thiab tempering ntawm cov hlau me me. Lub qhov cub kub kub kuj tseem siv tau rau cov cua kub kub xws li sintering, dissolution, thiab tsom xam cov hlau thiab ceramics.

"Cov khoom siv refractory ntawm lub cub tawg tshiab muaj cov dej noo. Tsis tas li ntawd, txhawm rau tsim cov txheej txheem oxide ntawm cov cua sov, nws yog ib qho tsim nyog yuav tsum tau ci ntawm qhov kub qis rau ob peb teev thiab maj mam nce qhov kub mus rau 900 degree ua ntej pib siv, thiab tuav nws rau ntau tshaj 5 teev los tiv thaiv lub cub tawg los ntawm kev tawg vim qhov kub thiab txias hloov sai tom qab raug cuam tshuam los ntawm ya raws. "
Thaum cua sov nyob rau hauv ib tug muffle furnace, lub qhov cub lub tsho yuav kub. Khaws lub cub tawg kom deb ntawm cov khoom siv hluav taws xob thiab ua kom yooj yim rau dissipate cua sov sab nraum lub qhov cub.
"Lub neej ua haujlwm ntawm lub tshuab cua sov yog nyob ntawm cov txheej txheem oxide ntawm nws qhov chaw. Kev rhuav tshem cov txheej txheem oxide yuav ua rau lub neej ntawm cov cua sov ua kom luv, thiab txhua qhov kev kaw yuav ua rau cov txheej txheem oxide puas. Yog li ntawd, nws yog ib qho tseem ceeb kom tsis txhob kaw tom qab pib. ".
"Thaum siv, qhov kub ntawm lub cub tawg yuav tsum tsis txhob siab tshaj qhov kub siab tshaj plaws kom tsis txhob kub hnyiab tawm cov hluav taws xob cua sov, thiab nws yog txwv tsis pub txhaj ntau yam kua thiab molten hlau rau hauv lub cub tawg."
Thaum ua qhov kev ntsuam xyuas ashing, nws yog ib qho tsim nyog yuav tsum tau ua kom tag nrho cov qauv ntawm lub cub hluav taws xob ua ntej muab tso rau hauv lub qhov cub ashing kom tiv thaiv cov pa roj carbon monoxide los ntawm kev puas tsuaj rau cov cua sov.
Tom qab ob peb lub voj voog ntawm cov cua sov, cov kab nrib pleb yuav tshwm sim hauv cov khoom siv insulating ntawm lub qhov cub, uas yog tshwm sim los ntawm thermal expansion thiab tsis muaj kev cuam tshuam rau qhov zoo ntawm lub cub tawg.
Lub qhov cub muffle yog ib qho kev sim thiab yuav tsum tsis txhob siv rau lwm lub hom phiaj. Cov qauv yuav tsum tau muab tso rau hauv lub crucible huv si thiab yuav tsum tsis txhob ua paug rau lub qhov cub.
8. Thaum siv lub tshuab hluav taws xob tiv thaiv, nws yuav tsum tau ua tib zoo saib xyuas kom tsis txhob muaj xwm txheej tshwm sim los ntawm kev tswj tsis siv neeg. Thaum tsis muaj ib tus neeg ua haujlwm hmo ntuj, tsis txhob siv lub qhov cub ua haujlwm.
Tom qab siv lub muffle rauv, txiav tawm lub hwj huam mov kom nws txias. Lub qhov rooj cub tawg yuav tsum tsis txhob qhib tam sim ntawd kom tsis txhob muaj qhov txias txias ntawm lub qhov cub. Thaum muaj xwm txheej ceev, lub qhov me me tuaj yeem qhib ua ntej kom ceev qhov kub thiab txias. Lub qhov cub qhov rooj tsuas yog qhib thaum qhov kub thiab txias qis dua 200 degree.
10. Thaum siv lub cub tawg, ua tib zoo saib xyuas kev nyab xeeb thiab tsis txhob scalding.
