Silicio karbidas (SiC) - tai itin kietas, sintetiniu b\u016bdu pagamintas kristalinis silicio ir anglies junginys, kuris jau seniai naudojamas pjovimo \u012frankiams, \u0161vitriniam popieriui, siurbli\u0173 ir raketini\u0173 varikli\u0173 dilimui atsparioms dalims, ugniai atspariems pramonini\u0173 krosni\u0173 \u012fd\u0117klams, siurbli\u0173 ir raketini\u0173 varikli\u0173 dilimui atsparioms dalims ir net puslaidininkiniams \u0161viesos diod\u0173 (LED) substratams gaminti. Nuo XIX a. pabaigos SiC taip pat pla\u010diai naudojamas. Pastaruoju metu jis taip pat naudojamas kaip pramonini\u0173 krosni\u0173 ugniai atspar\u016bs \u012fd\u0117klai, kaip dilimui atsparios siurbli\u0173 ir raketini\u0173 varikli\u0173 dalys, kaip puslaidininkiniai \u0161viesos diod\u0173 (LED) substratai.<\/p>\n
Silicio karbido kaitinimo elementai yra nemetaliniai elektrin\u0117s var\u017eos kaitinimo elementai, kurie, tekant srovei, generuoja \u0161ilum\u0105, tod\u0117l puikiai tinka pramonin\u0117ms krosnims, kuriose reikia reguliuoti auk\u0161t\u0105 temperat\u016br\u0105 \u012fvairiose srityse, pavyzd\u017eiui, metalo terminio apdorojimo, keramikos ir stiklo gamybos, puslaidininki\u0173 gamybos ir kt.<\/p>\n
D\u0117l ma\u017eos var\u017eos EREMA elementai yra ekonomi\u0161kas b\u016bdas \u0161ildyti krosn\u012f nenaudojant d\u016bm\u0173 duj\u0173 - taip u\u017etikrinama geresn\u0117 darbo aplinka ir ilgesnis element\u0173 tarnavimo laikas kontroliuojant oksidacij\u0105. M\u016bs\u0173 \"NoAgeTM\" technologija dar labiau prailgina j\u0173 tarnavimo laik\u0105.<\/p>\n
\"American Elements\" si\u016blo didelio tankio rekristalizuotus SiC elementus, skirtus keramikos degimui, floatinio stiklo gamybai, spalvot\u0173j\u0173 metal\u0173 lydymo procesams, tokiems kaip sukepinimas ir litavimas, taip pat kitiems pramoniniams procesams, kuriems reikalinga temperat\u016bra iki 1625oC. \u0160ie elementai yra stryp\u0173 arba vamzd\u017ei\u0173 su viena arba keliomis kojel\u0117mis su metalizuoto aliuminio galiniais kra\u0161tais pavidalo; be to, jie gali b\u016bti \u012fvairi\u0173 geometrij\u0173, kad atitikt\u0173 klient\u0173 gamini\u0173 dizaino specifikacijas ir krosni\u0173 kriterijus.<\/p>\n
Silicio karbido kaitinimo elementai yra atspar\u016bs auk\u0161tai temperat\u016brai ir oksidacijai, tod\u0117l pailg\u0117ja j\u0173 naudojimo laikas \u012fvairiose krosnyse, pavyzd\u017eiui, keramikos, stiklo, miltelin\u0117s metalurgijos ir analiz\u0117s srityse. D\u0117l savo ilgaam\u017ei\u0161kumo jie yra patikimas pasirinkimas.<\/p>\n
Silicio karbido \u0161ildytuv\u0173 var\u017ea kinta netiesi\u0161kai priklausomai nuo temperat\u016bros. Kad elementas neb\u016bt\u0173 \u012fjungtas per didele galia, turi b\u016bti \u012fdiegta patikima valdymo sistema; jos tikslas tur\u0117t\u0173 b\u016bti nustatyti taip, kad darbin\u0117 galia b\u016bt\u0173 ma\u017eesn\u0117 ir \u012f kair\u0119 nuo \"\u0160ildytuvo galios ribin\u0117s kreiv\u0117s\".<\/p>\n
Daugelis element\u0173 yra apdoroti MHI NoAgeTM apdorojimu, kad b\u016bt\u0173 i\u0161vengta laipsni\u0161kos oksidacijos ir silicio dioksido susidarymo, kuris gali padidinti atsparum\u0105 per vis\u0105 j\u0173 eksploatavimo laikotarp\u012f. Be to, \"NoAgeTM\" padeda apsaugoti elementus nuo cheminio proceso gar\u0173 poveikio, kuris gali pa\u017eeisti j\u0173 dang\u0105 arba sukelti mechanin\u012f gedim\u0105.<\/p>\n
Silicio karbidas pasi\u017eymi dideliu mechaniniu atsparumu ir ma\u017eu \u0161iluminiu pl\u0117timusi, tod\u0117l j\u012f galima naudoti itin auk\u0161toje temperat\u016broje neprarandant tvirtumo. D\u0117l \u0161io savybi\u0173 derinio silicio karbidas yra puikus \u0161ildymo element\u0173, naudojam\u0173 sm\u016bgi\u0173 veikiamose srityse, med\u017eiag\u0173 pasirinkimas.<\/p>\n
Silicio karbidas geriau nei kiti metalai, pavyzd\u017eiui, aliuminis, atlaiko agresyvi\u0105 krosnies aplink\u0105, nes yra atsparus i\u0161lydyt\u0173 drusk\u0173, \u0161arm\u0173 ar r\u016bg\u0161\u010di\u0173 poveikiui, t. y. jo atsparumas rei\u0161kia, kad jis gali atlaikyti agresyvi\u0105 krosnies aplink\u0105, kuri pakenkt\u0173 kitiems kaitinimo elementams ir sutrumpint\u0173 j\u0173 tarnavimo laik\u0105.<\/p>\n
D\u0117l ma\u017eo SiC element\u0173 atsparumo tempimui gali kilti tam tikr\u0173 sunkum\u0173, ta\u010diau tai galima kompensuoti suderinant j\u0173 atsparum\u0105, padidinant ilgaam\u017ei\u0161kum\u0105 ir i\u0161vengiant pa\u017eeidim\u0173 eksploatacijos metu. Be to, \u0161ie elementai labai atspar\u016bs \u012fprastoms technologin\u0117ms dujoms ir chemin\u0117ms med\u017eiagoms, tod\u0117l suma\u017e\u0117ja technin\u0117s prie\u017ei\u016bros poreikis, eksploatavimo i\u0161laidos ir prastovos.<\/p>\n
M\u016bs\u0173 DM tipo silicio karbido kaitinimo elementai pritaikyti naudoti pramonin\u0117se krosnyse, metalo terminiam apdorojimui, keramikos ir stiklo gamini\u0173 gamyboje bei puslaidininki\u0173 gamyboje. J\u0173 kieta, bet trapi konstrukcija atlaiko staigius \u0161al\u010dio ir kar\u0161\u010dio poky\u010dius, nesideformuodama auk\u0161toje temperat\u016broje.<\/p>\n
\"Globar sic\" kaitinimo elementai pasi\u017eymi auk\u0161ta darbine temperat\u016bra, atsparumu oksidacijai ir korozijai, ilgaam\u017ei\u0161kumu, ma\u017ea deformacija ir paprastu montavimu. Jie pla\u010diai naudojami \u012fvairiose auk\u0161tos temperat\u016bros elektrin\u0117se krosnyse, naudojamose magnetini\u0173 med\u017eiag\u0173, keramikos, miltelin\u0117s metalurgijos, miltelini\u0173 metal\u0173 stiklo metalurgijos pramon\u0117je, taip pat kitose srityse, kuriose naudojami elektriniai \u0161ilumos \u0161altiniai, pvz.<\/p>\n
Galima naudoti \u012fvairias pavir\u0161iaus dangas, apsaugan\u010dias kaitinimo elementus nuo korozij\u0105 sukelian\u010di\u0173 proceso gar\u0173 ir prailginan\u010dias j\u0173 eksploatavimo trukm\u0119, pavyzd\u017eiui, apsaugines glaz\u016bras, silicio karbido ar volframo karbido ugniai atsparias aliuminio oksido dangas, metalo oksid\u0173 dangas arba m\u016bs\u0173 NoAge(r) apdorojim\u0105, kuris apsaugo kaitinimo elementus nuo kit\u0173 proceso gar\u0173 sukeliamos degradacijos; taip suma\u017einamas duj\u0173 poveikis ir prailginamas j\u0173 eksploatavimo laikas.<\/p>","protected":false},"excerpt":{"rendered":"
