Silicio karbido tigliai naudojami metal\u0173 lydymo procesuose i\u0161lydytai med\u017eiagai apsaugoti nuo u\u017eter\u0161imo ir dilimo, atlaiko auk\u0161t\u0105 temperat\u016br\u0105, pasi\u017eymi puikiu cheminiu atsparumu ir ilgaam\u017ei\u0161kumu.<\/p>\n
SiC grafito tigli\u0173 kaitinimas prie\u0161 naudojim\u0105 pad\u0117s i\u0161vengti fizini\u0173 pa\u017eeidim\u0173, nes pa\u0161alins dr\u0117gm\u0119, kuri susikaup\u0117 gamybos, sand\u0117liavimo ir transportavimo metu.<\/p>\n
Silicio karbidas (SiC) yra itin patvari med\u017eiaga, naudojama liejimo tigliams gaminti. \u0160ie indai naudojami metalui lydyti ir laikyti liejimo proceso metu, tod\u0117l jie turi atlaikyti ekstremalias temperat\u016bras ir \u0161iluminius sm\u016bgius, nesudu\u017eti ir b\u016bti atspar\u016bs korozijai, kad pailg\u0117t\u0173 j\u0173 tarnavimo laikas. SiC tigliai yra idealus pasirinkimas d\u0117l j\u0173 i\u0161skirtinio atsparumo kar\u0161\u010diui ir antikorozini\u0173 savybi\u0173.<\/p>\n
Gamybos proceso metu gamintojai i\u0161 grafito milteli\u0173 suformuoja tiglius ir juos kepa krosnyje arba krosnel\u0117je prie\u0161 impregnuodami pik\u012f ir grafitizuodami. Po to \u0161ie tigliai turi b\u016bti nuodugniai i\u0161bandyti, kad b\u016bt\u0173 \u012fsitikinta, jog jie atitinka specifikacijas; \u0161i\u0173 grie\u017et\u0173 egzamin\u0173 metu, siekiant patikrinti j\u0173 ilgaam\u017ei\u0161kum\u0105, taikoma ekstremali temperat\u016bra ir sl\u0117gis.<\/p>\n
Nors SiC grafito tigliai yra gana atspar\u016bs terminiam \u0161okui, prie\u0161 naudojant rekomenduojama juos \u012fkaitinti. Taip tiglis per greitai nesu\u0161ils, tod\u0117l gali \u012ftr\u016bkti ir sudu\u017eti. Be to, labai svarbu, kad jis neb\u016bt\u0173 veikiamas med\u017eiag\u0173, kuriose yra korozini\u0173 ar reaktyvi\u0173 element\u0173, galin\u010di\u0173 pa\u017eeisti jo vientisum\u0105 arba u\u017eter\u0161ti nuodeg\u0173 nuos\u0117domis.<\/p>\n
Silicio karbido tigliai yra atspar\u016bs korozijai, tod\u0117l tinka tam tikroms reikm\u0117ms, o d\u0117l atsparumo \u0161iluminiam sm\u016bgiui tinka lydymui ir juod\u0173j\u0173 ir spalvot\u0173j\u0173 metal\u0173 lydini\u0173 liejimui. J\u0173 efektyvus \u0161ilumos perdavimas palengvina greitesnius lydymo ir au\u0161inimo procesus. Silicio karbido tigliai taip pat atlieka verting\u0105 vaidmen\u012f juvelyrini\u0173 dirbini\u0173 liejyklose lydant tauriuosius metalus, tokius kaip auksas, sidabras, platina ir varis.<\/p>\n
Rinkdamiesi idealiai tinkant\u012f tigl\u012f, tur\u0117tum\u0117te atid\u017eiai apsvarstyti krosnies tip\u0105, lydalo talp\u0105 ir lydom\u0173 metal\u0173 tip\u0105. Be to, jo suderinamumas su bet kokiais priedais ar fliusais, kuriuos galite naudoti, u\u017etikrins kuo ilgesn\u012f jo tarnavimo laik\u0105. Tikslus jos naudojimo \u017eurnalas pad\u0117s nustatyti, kada baigiasi jos naudojimo laikas.<\/p>\n
Korozija tigliuose paprastai pasirei\u0161kia \u012fdubimais ant j\u0173 dugno pavir\u0161iaus d\u0117l juose pl\u016bduriuojan\u010di\u0173 pried\u0173 ir metalo oksido. \u0160i\u0173 nuos\u0117d\u0173 galima i\u0161vengti naudojant geresn\u0117s kokyb\u0117s \u0161lak\u0105 ir palaikant kuo \u017eemesn\u0119 temperat\u016br\u0105. Be to, fliuso prid\u0117jimas po to, kai visas metalas visi\u0161kai i\u0161silydo, gali pad\u0117ti apsaugoti tiglius nuo tolesn\u0117s korozijos \u017ealos.<\/p>\n
Silicio karbido tigliai d\u0117l savo cheminio inerti\u0161kumo ir atsparumo r\u016bg\u0161tin\u0117ms ir \u0161armin\u0117ms med\u017eiagoms idealiai tinka naudoti su reaktyviaisiais elementais ir junginiais. D\u0117l savo inerti\u0161kumo jie taip pat tinka cheminei sintezei ir reakcijoms auk\u0161toje temperat\u016broje. Paprastai gaminami i\u0161 milteli\u0173 ir ri\u0161iklio mi\u0161inio, po to formuojami norimos formos tigliai ir degami labai auk\u0161toje temperat\u016broje iki visi\u0161ko sutank\u0117jimo ir stiprumo. Baigus degim\u0105, apdirbami matmenys ir atliekama pavir\u0161iaus apdaila, kad b\u016bt\u0173 galima pristatyti galutin\u012f gamin\u012f.<\/p>\n
\u0160ie tigliai idealiai tinka spalvotiesiems metalams ir lydiniams, tokiems kaip auksas ir sidabras, lydyti, liejant gele\u017e\u012f, taip pat metalurgijos laboratorijose atliekant eksperimentus auk\u0161toje temperat\u016broje. Jie ne tik atspar\u016bs korozijai, bet ir puikiai atlaiko terminius sm\u016bgius!<\/p>\n
Nor\u0117dami u\u017etikrinti kuo ilgesn\u012f silicio karbido grafito tiglio tarnavimo laik\u0105, u\u017etikrinkite, kad jis visada b\u016bt\u0173 sausas ir \u0161varus. Valydami j\u012f po kiekvieno naudojimo, u\u017etikrinkite, kad nuo jo pamu\u0161alo b\u016bt\u0173 reguliariai pa\u0161alinami visi \u0161lakai. Be to, registruodami, kaip da\u017enai ir koki\u0105 med\u017eiag\u0105 lydote, galite numatyti, kada laikas keisti tigl\u012f, ir lengvai nustatyti, kuris tiglis geriausiai tinka j\u016bs\u0173 krosniai.<\/p>\n
Silicio karbido tigliai pasi\u017eymi ma\u017eu \u0161iluminiu pl\u0117timusi ir yra puikus \u012frankis spalvotiesiems metalams, tokiems kaip auksas, sidabras, varis, aliuminis, \u0161vinas ir cinkas bei vidutinio anglingumo plienas, lydyti. D\u0117l geb\u0117jimo i\u0161tverti auk\u0161t\u0105 temperat\u016br\u0105 ir greitus kaitinimo \/ au\u0161inimo ciklus lydymo metu \u0161ie tigliai idealiai tinka tiek tauri\u0173j\u0173 metal\u0173 lydymo \/ liejimo procesams, tiek ir naudojimui krosnyse. Juos da\u017enai galima rasti naudojamus tauri\u0173j\u0173 metal\u0173 lydymo \/ liejimo procesuose, taip pat \u0161lifuotose krosnyse.<\/p>\n
Grafitas yra itin tvirta med\u017eiaga, gerai atlaikanti auk\u0161t\u0105 temperat\u016br\u0105 ir mechanin\u0119 apkrov\u0105. Ta\u010diau jis gali \u012ftr\u016bkti, jei tiglis perkaista arba staiga pasikei\u010dia temperat\u016bra; norint apsaugoti \u0161i\u0105 med\u017eiag\u0105, prie\u0161 naudojim\u0105 tigl\u012f reik\u0117t\u0173 u\u017edengti ir \u012fkaitinti.<\/p>\n
Tiglio pa\u017eeidimus gali b\u016bti sunku i\u0161taisyti. Viena i\u0161 da\u017eniausiai pasitaikan\u010di\u0173 komplikacij\u0173 - i\u0161ilginiai \u012ftr\u016bkimai jo pavir\u0161iuje, atsirandantys d\u0117l greito mygtuko \u012fkaitinimo arba cheminio poveikio, d\u0117l kurio atsiranda \u012ftr\u016bkim\u0173. Kita galima problema yra pa\u017eeidimai d\u0117l dilimo arba cheminio poveikio, d\u0117l kuri\u0173 taip pat gali atsirasti \u012ftr\u016bkim\u0173.<\/p>\n
Norint suma\u017einti \u0161i\u0105 galimyb\u0119, labai svarbu reguliariai valyti ir nuvalyti kalkes, kad i\u0161 tiglio b\u016bt\u0173 pa\u0161alintos nuodegos - tai neleis joms paveikti b\u016bsim\u0173 lydal\u0173 ir apsaugos j\u012f nuo chemini\u0173 med\u017eiag\u0173 poveikio. Be to, stenkit\u0117s nepiktnaud\u017eiauti fliuso priedais - fliusas gali sugadinti tiglius, nes sukuria \u012ftempimo ta\u0161kus, nenumatytus j\u0173 konstrukcijoje, ir taip padidina kit\u0173 indo viet\u0173 apkrov\u0105.<\/p>","protected":false},"excerpt":{"rendered":"
