Iityhubhu ezikhazimlayo ze-silicon carbide

Iityhubhu ezikhazimlayo ze-silicon carbidengamacandelo e-ceramic aphambili amkelwa ngokubanzi ngomsebenzi wawo obalaseleyo kubushushu obuphezulu kunye nezicelo zemizi-mveliso ezonakalisayo. Iimpawu zabo zemathiriyeli ezizodwa kunye nokulungelelaniswa kolwakhiwo kubenza babaluleke kakhulu kwiindawo ezisebenza nzima. Apha ngezantsi kukho isishwankathelo seenzuzo zabo eziphambili kunye nezicelo.

1. IiPropati zeMathiriyeli eziPhezulu

I-SiC yimathiriyeli ye-ceramic esebenza kakhulu eneempawu ezibalaseleyo:

(1) Ukuchasana nobushushu obugqithisileyo: Ukukwazi ukusebenza ngokuqhubekayo kumaqondo obushushu ukuya kuthi ga kwi-1600 ° C kunye nokuvezwa kwexesha elifutshane elidlula i-1800 ° C, ukugqwesa izisombululo zemveli ezisekelwe kwisinyithi.

(2) I-High Thermal Conductivity: Nge-thermal conductivity 2-3 amaxesha aphezulu kunezinyithi, iibhubhu ze-Silicon carbide radiant zivumela ukufudumeza ngokukhawuleza kunye nokusabalalisa ukushisa okufanayo.

(3) Ukwandiswa kweThermal ephantsi: Ukwandiswa kwe-thermal encinci kunciphisa uxinzelelo ngexesha lokutshintsha kweqondo lokushisa, ukuqinisekisa ukuzinza kwesakhiwo.

(4) Ukuxhathisa ukuMnyama kunye ne-Oxidation: Ukumelana ne-asidi, i-alkalis, isinyithi esityhidiweyo, kunye neegesi ezinobundlongondlongo, naphantsi kweemeko zobushushu obuphezulu.

2.Ukuguquguquka kweZakhiwo

Iityhubhu ze-silicon carbide ezikhanyayo zinokulungelelwaniswa neemfuno ezahlukeneyo zamashishini:

(1) Uyilo oluSetyenziswa ngokwezifiso: Ifumaneka ngokuthe tye, i-U-shaped, okanye i-W-shaped configurations ukulungiselela ukusasazwa kobushushu kunye nokusetyenziswa kwendawo.

(2) Ukudityaniswa okuqinileyo: Iyahambelana neeflange zetsimbi okanye iinkqubo zokutywinwa ze-ceramic zokudibanisa ubungqina bokuvuza kwiisethingi ezinzima.

1. Izinto eziluncedo ngokuSebenza

(1) Ukusebenza kakuhle kwamandla: Ukuhanjiswa okuphezulu kwe-thermal kunciphisa ukusetyenziswa kwamandla ngokuvumela ukuhanjiswa kobushushu ngokukhawuleza.

(2) Ubomi beNkonzo ende: Iityhubhu ze-silicon carbide ezikhanyayo zihlala zihlala ixesha elide le-3-5 kunezinye iindlela zetsimbi kwiindawo ezinzima, ukunciphisa ixesha lokuphumla kunye neendleko zokutshintsha.

(3) Ukumelana ne-Thermal Shock: Ukumelana nokufudumeza ngokukhawuleza kunye nemijikelo yokupholisa ngaphandle kokuqhekeka, ilungele iinkqubo ezifuna utshintsho rhoqo lobushushu.

4. Izicelo eziphambili zoShishino

Iityhubhu ze-silicon carbide radiant zigqwesa kumacandelo abalulekileyo:

(1) I-Metallurgy: Isetyenziswa kwiziko lokutshisa, iziko lokutshisa i-carburizing, kunye neenkqubo zokubrawuza kunyango olufanayo lobushushu.

(2) Ukulungiswa kweeChemical: Khonza njengeetyhubhu zokusabela okanye i-catalyst isekela kwi-reactors ephezulu yobushushu kunye ne-pyrolysis furnaces.

(3) I-Ceramics / Glass Manufacturing: Qinisekisa ulawulo oluchanekileyo lokushisa kwii-sintering kilns kunye ne-glass-melting furnaces.

(4) Iinkqubo zokusiNgqongileyo: Ifakwe kwiindawo zokutshisa inkunkuma kunye neeyunithi zonyango zokukhupha ukujongana neegesi ezinobungozi kumaqondo aphezulu aphezulu.

5.Izinto eziluncedo zokuthelekisa ngaphaya kweendlela ezizezinye:

6. Kutheni ukhetha iityhubhu ze-Silicon carbide radiant?

Iityhubhu ezikhazimlayo zeSilicon carbide lolona khetho lufanelekileyo kumashishini abeka phambili:

(1) Uzinzo olugqithisileyo lobushushu ngaphandle kokuthotywa kokusebenza.

(2) Ukuthembeka kwexesha elide kwi-atmosphere eyonakalisayo okanye ene-oxidizing.

(3) Ukufudumeza amandla kunye okufanayo kwiinkqubo eziqhutywa ngokuchanekileyo.

I-Shandong Zhongpeng Special Ceramics Co., Ltd yenye yezona zisombululo zikhulu ze-silicon carbide zeceramic ze-ceramic e-China. I-ceramic yobugcisa be-SiC: Ubunzima be-Moh yi-9 (ubunzima be-Moh entsha yi-13), kunye nokumelana okugqwesileyo kukhukuliseko kunye ne-corrosion, i-abrasion egqwesileyo - ukuxhathisa kunye ne-anti-oxidation. Ubomi benkonzo yemveliso ye-SiC yi-4 ukuya kwamaxesha ama-5 ubude ngaphezu kwe-92% yezinto ze-alumina. I-MOR ye-RBSiC yi-5 kumaxesha e-7 ye-SNBSC, ingasetyenziselwa imilo enzima ngakumbi. Inkqubo yekoteyishini ikhawuleza, ukuhanjiswa kuthenjisiwe kwaye umgangatho ungowesibini. Sihlala sizingisa ukucela umngeni kwiinjongo zethu kwaye sibuyisele iintliziyo zethu kuluntu.
