Ungayenza njani imbethekile

Njengesixhobo esibalulekileyo kwitekhnoloji yokuhlaselwa yanamhlanje,I-Silicon Carbide iMbulalingokuthe ngcembe saba sisikhongozelo esithandwayo sokunyibilika inyibilike yentsimbi ngenxa yokusebenza ngokugqibeleleyo kunye neepropathi ezizodwa zezinto ezizodwa. Ingakumbi xa kusetyenzwa ukuba inyibiliki yentsimbi yentsimbi, i-Silicon Carbide Crubibs ibonise uthotho lweenzuzo zobugcisa. Eli nqaku liza kuzisa ngokweenkcukacha iimpawu zentsebenzo ze-Silicon Carbide, isicelo sayo kwiinkqubo zokuphosa, kunye nendlela yokubonelela ngezisombululo ezifanelekileyo nezinokuthembekileyo kwiinkampani zanamhlanje.

1. Yintoni i-carbide ye-carbide?
I-Silicon Carbide iMnandi sisitya esineqondo lobushushu lisebenzisa i-Silicon Carbide (i-SIC) njengeyona nto iphambili. Isetyenziselwa ikakhulu ukunyibilikisa kunye nokulungisa izinyithi ezahlukeneyo kunye ne-alloys. I-Silicon Carbide yinto yezinto zokwenziwa ngobukhali obukhulu kakhulu kunye nokuchasana nobushushu. Isetyenziswe ngokubanzi kwimihlaba ephezulu ye-tektie-teknoloji efana ne-ceramics, i-metallgy, kunye ne-semicondytors.

Kuba i-Silicon Carbide ineempawu ezibalaseleyo zomzimba kunye neekhemikhali ezinje ngembonakalo ephezulu ye-subrmal, ukwandiswa okuphakathi komhlaba okuphezulu, ukwandiswa kwe-themishini ephantsi, kunye nokungaxhathisi, kunye nokuziqhelanisa nokuziphatha kwamaqondo obushushu kunye neemeko eziphezulu.

I-2. Izibonelelo zobugcisa ze-silicon carbide intle
1. Ukunganyangeki okuphezulu kobushushu obuphezulu
I-Silicon Carbide Drubibles inamamela obushushu kakhulu obungaphantsi kwaye inokumelana nobushushu obuthile kwi-1600 ° C. Oku kubangela ukuba balungele ukunyibilikisa iintsimbi eziphakamileyo ezinjalo ngobhedu, ialuminium kunye ne-nickel. Compared with crucibles made of other materials, the strength of silicon carbide crucibles does not decrease significantly under high temperature conditions, ensuring its shape stability during the smelting process.

Olu lwazi luphezulu lobushushu oluphezulu lunceda iinkampani zithintele iinqaba ekusebenziseni okanye zokuqhekeka ngenxa yobushushu obuphezulu, ngaloo ndlela kuphucule ukuqhubeka kwemveliso kunye nokusebenza kakuhle.

2. Ukuqhubela phambili kwengqondo
Elinye inqaku elibonakalayo lezixhobo ze-selicon carbide yimfundiso yayo ephezulu ye-shirmal, evumela ukuba idluliselwe ngokukhawuleza. Oku kuthetha ukuba ngexesha lenkqubo yokunyibilika, isinyithi esityhidiweyo sinokufikelela ngokukhawuleza kwiqondo lokushisa elifunekayo, ukunciphisa ixesha lokulila kunye nokuphucula ukusebenza kwemveliso.

Le nkqubo isebenzayo yobushushu ikwanciphisa ukugqithisa intsimbi ye-molten, ukunceda ekufezekiseni ulawulo lobushushu obungaphezulu ngexesha lenkqubo yokuphosa kunye nokuqinisekisa ukuba kusemgangathweni oqhubekayo.

I-3. Ukwanda okuphezulu kwe-thermal
Ukunyanzelwa kokwandiswa kwe-shirrm kubhekiselelwa kwinqanaba lokwanda kwesixhobo kumthamo xa ushushu. I-Silicon Carbide inelungelo lokufumana ulwandiso lwe-shirmal, oko kuthetha ukuba lutshintsha kancinci ngobukhulu xa ubushushu. Ke ngoko, nakwindawo enobunkunkqele obunobushushu obuqinileyo, i-selicon carbide intle inokugcina imilo yayo yoqobo kwaye inqande ukuntywila okanye ukonakala ngenxa yokwandiswa okanye ukonakaliswa.

Ukwanda kwe-thermal osezantsi kufanelekile kwiinkqubo zokuphosa kubandakanya rhoqo ngemijikelezo yokufudumeza kunye nemijikelezo epholileyo, inkonzo yobomi benkonzo yokubethelwa.

4. Ukunganyangeki kwe-corosion efanelekileyo
Ngexesha lenkqubo yokunyibilikisa, i-molten yentsimbi iqala ngentsimbi enqabileyo, ngokuthe ngcembe ikhulisa umphezulu wayo. Nangona kunjalo, izinto ze-selicon ze-silicon zinengxaki yokulwa kakuhle yekhemikhali kwaye zinokuxhathisa ngokukhuselekileyo kotywala besinyithi, ngakumbi xa ujongene neentsimbi ezisebenzayo kakhulu ezinje ngobhedu kunye ne-aluminium.

Ukunganyangeki kwe-corosions elungileyo akunakubekisisela ubomi benkonzo, kodwa kunciphisa ukungcola okunokubangelwa kukuvela kwindawo enqamlezileyo, ekuqinisekiseni umgangatho wemveliso yokugqibela.

I-5. Amandla aphezulu ombane
I-Silicon Carbide i-Carbibles igcina amandla omatshini oPhezulu kunye namaqondo obushushu aphezulu, esenza ukuba banciphise okanye baphelise. Olu phawu luphezulu lukwenza ukuba umntu abe naye abe nokumelana nefuthe loxinzelelo lwensimbi kunye noxinzelelo lwangaphandle, ukugcina uzinzo lwezakhiwo, ukugcina uzinzo lwesakhiwo ngexesha lokunyibilika kobushushu.

I-6. Uzinzo oluhle kakhulu
Uzinzo olothusayo lubhekisa kubuchule bezinto zokuba zixhathise ukuqhekeka xa ubushushu butshintsha ngokukhawuleza. I-Silicon Carbide the Makes Instait uzinzo obothusayo kwaye ziyakwazi ukumelana nokuhamba ngokukhawuleza kweqondo lobushushu ngaphandle kokuqhekeka. Oku kubaluleke kakhulu ekuphoseni iinkqubo ezifuna ukufudumeza rhoqo nokupholisa.

Ntathu. Ukusetyenziswa kwe-Silicon Carbide ther
Ngenxa yokunganyangeki kweqondo lobushushu ephezulu, ukuqhubela phambili kwengqondo, kunye nokunganyangeki kwe-corrosion, i-Silicon carbide isetyenziswa ngokubanzi kwiinkqubo zokunyibilikisa kunye nokuphosa inyibilikisi. Oku kulandelayo ziimeko eziqhelekileyo zesicelo:

Ukuphosa ubhedu: xa unuka ubhedu,I-Silicon Carbide iMbulalis unokugcina i-iyuni iyunifomu ye-iyunifomu, ukunciphisa ukwenziwa kokungcola, kunye nokuphucula umgangatho weenxalenye zobhedu.
I-Aluminium kunye ne-Aluminium Alting: I-Alumumium iphinda iphindwe ngenkuthalo ngexesha lokunyibilika, kodwa ukunganyangeki kohlobo lwe-silicon carbide ukukhusela ukunqongophala kweAluminiyam kwaye kususela ebomini bayo.
Olunye uncumo lobushushu obuphezulu: I-Silicon Carbide iMnandi ikwakulungele ukunyibilikisa iintsimbi zeqondo eliphezulu njenge-zinc kunye ne-nickel, kwaye zilungelelaniswe kakhulu.

Ezine. Sebenzisa kunye nokugcinwa kwe-silicon carbide the ther
Ukwandisa ubomi benkonzo ye-silicon carbide, ukusetyenziswa ngokuchanekileyo kunye nokugcinwa kubalulekile. Nazi ezinye zeengcebiso:

Phambili, ngaphambi kokuba usebenzise ukuqalisa okanye ukusetyenziswa kwakhona, kuyacetyiswa ngokuthe ngcembe ukunqanda ubushushu bokukhula nokuqhekeka.
Kulumkele ukufudumeza okukhawulezayo kunye nokupholisa: Nangona i-Silicon Carbide inezinzo ezilungileyo zothusayo, ukutshintsha kweqondo lobushushu ngokukhawuleza kunokwenzakalisa itheko.
Ukuhlolwa rhoqo: Ngexesha lokusetyenziswa, hlala ujonge indawo enqamlezileyo kwiimpawu ze-rocks okanye i-corosion, kwaye uzisombulule iingxaki ezinokubakho ngexesha elifanelekileyo.
