Kab rov tav actting yuav tsum tau txav cov khoom siv molten los ntawm kev tuav crucible rau graphite tuag thiab txias los ua ke tsis muaj kev sib tsoo. Tom qab mus los ntawm graphite tuag thiab ob peb tuav cov khoom, cov khoom siv molten thaum kawg hla dhau ntawm lub nplhaib tawg kom nkag mus rau qhov chaw sib cais. Nws yog qhov tseem ceeb uas lub nplhaib tawg tau khaws nws txoj kev ncaj ncees thaum muaj qhov kub thiab txias thaum thaj chaw kub (solidification cheeb tsam). Nws yuav tsum tso cai rau molten cov khoom kom khiav dawb tsis muaj clinging rau lossis tsim tsa ntawm kev sib tshuam. Kev sib xyaw ua ke yog qhov tseem ceeb ntawm kab rov tav tas li casting, txawm tias lawv tshwm sim los ua qhov ncaj ncaj ntawm cov kev sib dhos tiav. Tag nrho cov cua sov yuav ploj mus hauv qhov kev tshwm sim uas cov seem no ua tsis tau lossis tawg, yuav tsum tau muaj kev nyab xeeb ntawm downtime rau feem hloov thiab kev tu.

Boron NitrideCov khoom ua kom pom zoo siab-kub tsis kam, hluav taws xob rwb thaiv tsev, thiab cua sov. Ntawm 1800 ° C, nws ua rau pom cov tshuaj ruaj khov thiab tseem ruaj khov rau cov roj carbon thiab carbon monoxide. Tsis tas li ntawd, Molten hlau, molten ntsev, thiab tsis-oxide slag tsis corrode nws. Ib qho ntxiv, BN tej zaum yuav tsim tawm rau hauv cov kev ntsuas siab thiab yog machinable. Kab rov tav nruam casting sib cais cov nplhaib ntawm Molten hlau tau ua rau kev siv ntawm Boron Nitride Rings. Nyob rau hauv ib qho chaw huab cua nrog lub tshuab nqus tsev siab, nws tuaj yeem txuas ntxiv ntub thaum muaj kev kub siab.

Boron NitrideNtiv nplhaib zoo

Tsawg Hlau Molten Wettability
Tsawg thermal expansion thiab sib piv muaj zog heev thermal conductivity
Ib qho kev sib piv tau zoo rau kev ua kom sov
Kev khiav hauj lwm kub heev nrog kev tiv thaiv tsim nyog tiv thaiv cov pa roj hauv plab

Bn Ceramicmuaj ntau hom sib xyaw,Tus snbnUa kom zoo tshaj plaws hauv cov kab rov tav nrum cov khoom siv:

Thaum nws los txog rau cov kab rov tav sib txuas ua ke ntawm cov hlau tsis muaj hlau,Snbn (Boron Nitride + Silicon Nitride)Puas yog ceramics ua yeeb yam zoo. Lub rings yog qhov zoo meej rau kev lees paub lub hnub ruaj khov thiab meej meej thaum lawv tsis-ntub rau molting hlau, oxidation-resistant, thiab xaim inert.

Qhov zoo ntawmSnbn Rhuav Lub Npog

Oxidation Resistant: txog li 1000 ° C hauv huab cua
High-temp Stable: Hauv lub tshuab nqus tsev lossis hauv roj av, nce mus txog 1700-1800 ° C
Tsis yog-ntub: txwv tsis pub swb thiab hlau los ntawm Adhering
Yaig thiab Corrosion: withstands reactive hlau thiab yog resistant

Qhov zoo ntawm covSnbn Rhuav Lub NpogPiv rau cov cim graphite

Snbn Heramic Rhuav Rings, uas tsim rau kev ua yeeb yam ntawm cov txheej txheem sib xyaw ua ke, zoo dua li cov kab sib kis tau vim tias lawv tsis muaj pa roj carbon monomat. Lawv qhov tsis ntub dej nto thiab cov qauv muaj zog nyob rau hauv tshav kub cycling lav zoo dua li qub thiab du molten hlau ntws.
