N\u00ebse keni kaluar ndonj\u00ebher\u00eb koh\u00eb pran\u00eb furrave industriale ose furrave me temperatur\u00eb t\u00eb lart\u00eb, e dini q\u00eb element\u00ebt ngroh\u00ebs p\u00ebsojn\u00eb d\u00ebme t\u00eb m\u00ebdha. Kam hyr\u00eb n\u00eb shum\u00eb impiante ku element\u00ebt metalik\u00eb ishin duke u p\u00ebrkulur ose po digjeshin shum\u00eb shpejt, dhe disa opsione qeramike thjesht nuk mund t\u00eb p\u00ebrballonin ciklet e vazhdueshme termike. K\u00ebtu shufrat prej karbidi silikoni kan\u00eb fituar reputacionin e tyre me kalimin e viteve.<\/p>\n

K\u00ebto shufra jan\u00eb b\u00ebr\u00eb nga karbidi i silicit me past\u00ebrti t\u00eb lart\u00eb, i cili formohet dhe m\u00eb pas sinterizohet n\u00eb temperatura jasht\u00ebzakonisht t\u00eb larta.

Ajo q\u00eb m\u00eb p\u00eblqen tek ato \u00ebsht\u00eb se formojn\u00eb vet\u00eb nj\u00eb shtres\u00eb mbrojt\u00ebse silik\u00eb kur nxehen. Kjo shtres\u00eb ndihmon n\u00eb ngadal\u00ebsimin e oksidimit t\u00eb m\u00ebtejsh\u00ebm, gj\u00eb q\u00eb \u00ebsht\u00eb nj\u00eb arsye e madhe pse ato mund t\u00eb zgjasin shum\u00eb n\u00ebse furra \u00ebsht\u00eb vendosur si duhet.<\/p>\n

N\u00eb praktik\u00eb, shufrat prej karbidi silikoni p\u00ebrdoren n\u00eb pjekjen e qeramik\u00ebs, shkrirjen e qelqit, metalurgjin\u00eb me pluhur dhe n\u00eb t\u00eb gjitha llojet e trajtimeve termike.

I kam par\u00eb t\u00eb vazhdojn\u00eb t\u00eb funksionojn\u00eb n\u00eb cikle q\u00eb do t\u00eb shkat\u00ebrronin shum\u00eb element\u00eb metalik\u00eb.<\/p>\n

N\u00eb krahasim me element\u00ebt MoSi\u2082, ato shpesh jan\u00eb m\u00eb me kosto efektive p\u00ebr shum\u00eb procese oksiduese dhe mund t\u00eb jen\u00eb pak m\u00eb t\u00eb tolerueshme n\u00eb p\u00ebrdorimin e p\u00ebrditsh\u00ebm, megjithat\u00eb secili ka vendin e vet.<\/p>\n

Megjithat\u00eb, ato nuk jan\u00eb t\u00eb p\u00ebrsosura. \u00c7\u00ebshtja m\u00eb e madhe praktike \u00ebsht\u00eb se rezistenca e tyre rritet me kalimin e koh\u00ebs.

Kam v\u00ebn\u00eb re se shkaqet kryesore t\u00eb d\u00ebshtimit t\u00eb hersh\u00ebm zakonisht nuk jan\u00eb vet\u00eb materialet. Shpesh jan\u00eb kontrolli i dob\u00ebt i energjis\u00eb, kontaminimi nga atmosfera ose trajtimi i pap\u00ebrshtatsh\u00ebm.

Kostojn\u00eb m\u00eb shum\u00eb n\u00eb fillim sesa element\u00ebt metalik\u00eb t\u00eb zakonsh\u00ebm, por n\u00eb aplikimet q\u00eb k\u00ebrkojn\u00eb v\u00ebrtet temperatura t\u00eb larta dhe jet\u00ebgjat\u00ebsi t\u00eb gjat\u00eb, kostoja totale shpesh rezulton m\u00eb e favorshme sepse nuk keni nevoj\u00eb t\u00eb z\u00ebvend\u00ebsoni element\u00ebt \u00e7do disa muaj. Edhe nga ana e energjis\u00eb mund t\u00eb jen\u00eb t\u00eb favorshme, ve\u00e7an\u00ebrisht kur furra \u00ebsht\u00eb projektuar p\u00ebr nj\u00eb shp\u00ebrndarje t\u00eb mir\u00eb t\u00eb nxeht\u00ebsis\u00eb.<\/p>\n

Koh\u00ebt e fundit shum\u00eb nga shufrat m\u00eb t\u00eb reja vijn\u00eb me skajet e ftohta t\u00eb p\u00ebrmir\u00ebsuara dhe me nj\u00eb q\u00ebndrueshm\u00ebri m\u00eb t\u00eb mir\u00eb nga fabrika, gj\u00eb q\u00eb ndihmon si n\u00eb efikasitet ashtu edhe n\u00eb jet\u00ebgjat\u00ebsi.

N\u00eb fund t\u00eb fundit, ato nuk jan\u00eb ndonj\u00eb material mrekullie, por kur i p\u00ebrshtatni p\u00ebr pun\u00ebn e duhur dhe i trajtoni si duhet, ato thjesht vazhdojn\u00eb t\u00eb funksionojn\u00eb.
