Boron NitrideYog zoo meej rau ntau yam ntawm Molten Hlau Hu rau cov ntawv thov vim tias ntawm nws cov tshuaj lom neeg thermal tsis kam tawm tsam cov neeg feem coob ntawm Molten cov hlau. Ib qho txiaj ntsig ntxiv ntawm Boron Nitride tshaj cov conventional ceritection

Melted hlau ntws tsis tu ncua txuas ntxiv mus rau hauv pwm yog lub npe hu ua txuas ntxiv. Lub molten hlau ces solidifies mus rau hauv qhov ntev txuas ntxiv. Cov txheej txheem no yog npaj los tsim cov khoom hlau zoo li cov nplais pob zeb, billets, thiab kab teeb, thiab cov nqaj nyob hauv cov khoom sib txawv nrog cov kab hla sib xws. Nruam nruam cov txheej txheem ua ntej melting ntawm cov hlau, uas yog tom qab ntawd hliv rau hauv cov dej txias pwm. Cov hlau yog cov khoom tab sis tseem malleable raws li nws ncaim cov pwm. Qhov no ua rau nws yuav tsum ua kom zoo li ib qho uas tsis muaj kev cuam tshuam nrog cov txheej txheem casting.

Nruam casting muaj cov txiaj ntsig ntau ntau. Nws muab theem siab ntawm kev siv tshuab, uas txo tib neeg yuam kev thiab txo tus nqi ua haujlwm. Nruam casting kuj tseem yog qhov zoo heev, raws li nws ua rau:

• Ib qho kev lom zem heev

• Khib Txo

• Txo Kev Siv Zog

  
  

Kev lag luam uas yuav tsum muaj ntau ntau ntawm cov qauv ntsuas yog qhov tshwj xeeb yog qhov zoo rau kev txuas ntxiv mus txuas ntxiv. Qhov no ua rau kev tsim kho thiab tsheb tsim khoom lag luam, qhov twg qhov kev thov kom ci thiab cov nplais yog ob qho tib si sib xws thiab muaj ntau yam.

Cov txheej txheem ntawm cov khoom siv hlau meast, txawm nyob hauv lawv daim ntawv ntshiab lossis muaj kev sib hloov ntawm cov khoom siv ntawm cov khoom siv ua ntej ua ntej. Yuav kom lav cov txheej txheem kev sib xws, thiab kev ua tau zoo, nws yog qhov tsim nyog los ua kom zoo rau cov txheej txheem ntawm kub, thiab sib xyaw ua ke geometry.

Thaum ua haujlwm tau ua haujlwm ntau zaus casting thiab ncaj qha casting pwm los ua cov qauv zoo tagnrho cov duab, muaj ntau ntau yam los ntsuas. Qhov zoo ntawm cov khoom kawg yuav cuam tshuam los ntawm cov khoom ntawm cam, xws li hlau lossis ceramic. Cov khoom lag luam yuav tsum ntsuas cov khoom yuav nthuav tawm qhov tsis xws luag lossis cuam tshuam rau kev nthuav dav thermal.

Boron Nitridemuaj cov kev daws teeb meem zoo, txawm hais tias nyob rau hauv daim ntawv ntawm sintered Cheebtsam lossis thaum ua ntawv thov hauv cov kua tsim los tsim aBoron Nitridesab txheej.Qhov kev tso siab siab ntawmBoron NitrideTiv thaiv cov slurry thiab nws cov oxides los ntawm adhering rau saum npoo.Yog li ntawd, nws ua tau los txhim kho cov txheej txheem casting kev tsim khoom.

Hauv cov hlau casting cov ntawv thov,Boron Nitridetau qhia zoo ua hauj lwm zoo, tshwj xeeb tshaj yog nyob rau hauv nruam cam txuas. Kev sib tw Rings, ib qho kev hloov pauv ntawm cov chaw kub thiab txias ntawm txoj kab txuas mus ntxiv, yog tsim los ntawm cov kab kub uas tau nias lub ceron nitride ceramics uas tau machined. Qhov no yog ib qho tseem ceeb tab sis pheej yig ib qho kev tsis saib xyuas hauv cov txheej txheem casting. Cov yaj yuav tsum muaj peev xwm hla dhau lub nplhaib tawg thiab mus rau thaj chaw uas tsis muaj admering. Nws yuav tsum muaj peev xwm tiv thaiv kev hloov pauv hnyav heev. So cov nplhaib tsis ua haujlwm yuav yog kim heev. Vim li no, cov ntaub ntawv nrog cov coeffici tsis tshua muaj thiab muaj zog thermal poob siab kuj yog zoo meej.BNzoo heev nyob rau hauv daim teb no.
