Be to, d\u0117l atsparumo korozijai ir dilimui jie puikiai tinka vario, aliuminio, \u0161vino, cinko, anglies metalams, taip pat vidutinio sunkumo ar retiems lydiniams. Tiglius reik\u0117t\u0173 pakeisti, kai juose atsiranda nusid\u0117v\u0117jimo po\u017eymi\u0173, pavyzd\u017eiui, tinklelio pavidalo \u012ftr\u016bkim\u0173 ar \u012fdubim\u0173 vidiniame pamu\u0161ale, ma\u017eas lydymosi greitis arba l\u0117tas oksidacijos greitis.<\/p>\n
Tigliai atlieka svarb\u0173 vaidmen\u012f pramoniniuose ir laboratoriniuose procesuose, lydant med\u017eiagas itin auk\u0161toje temperat\u016broje. Galima \u012fsigyti \u012fvairi\u0173 form\u0173 ir dyd\u017ei\u0173 tigli\u0173, tinkam\u0173 \u012fvairioms reikm\u0117ms, o renkantis tiglius atsi\u017evelgiama \u012f j\u0173 darbin\u0119 temperat\u016br\u0105, med\u017eiag\u0173 savybes ir kain\u0105 - tarp populiariausi\u0173 pasirinkim\u0173 yra molio grafitas, silicio karbidas, cirkonio aliuminio oksidas ar net iridis.<\/p>\n
Norint pasiekti optimali\u0173 rezultat\u0173 lydant ir rafinuojant metalus bei kitas med\u017eiagas auk\u0161toje temperat\u016broje, labai svarbu pasirinkti tinkam\u0105 tigl\u012f. Tinkamas tiglis turi b\u016bti atsparus fiziniams pa\u017eeidimams ir cheminei korozijai, kartu palaikyti did\u017eiausi\u0105 lydymo greit\u012f, i\u0161eig\u0105 ir kokybi\u0161k\u0105 liejimo greit\u012f.<\/p>\n
sic tigliai, pasi\u017eymintys dideliu atsparumu terminiams sm\u016bgiams, yra idealus b\u016bdas suma\u017einti energijos s\u0105naudas didelio kar\u0161\u010dio aplinkoje - nuo lydymo ind\u0173 iki krosni\u0173. Be to, kai kuriuose modeliuose \u012frengta pirometro ki\u0161en\u0117, tod\u0117l stebint i\u0161lydyto metalo temperat\u016br\u0105 galima dar labiau suma\u017einti reaktyviosios energijos suvartojim\u0105, taigi ir energijos s\u0105naudas.<\/p>\n
Atsparumas fiziniams pa\u017eeidimams taip pat labai svarbus ilgalaikiam tiglio naudojimui. Sunki\u0173 metal\u0173 luit\u0173 ar kit\u0173 tanki\u0173 med\u017eiag\u0173 kritimas \u012f krosn\u012f gali pa\u017eeisti jos talpykl\u0105 ir sukelti ankstyv\u0105 jos gedim\u0105, tod\u0117l reik\u0117t\u0173 taikyti tinkam\u0105 \u012fkrovimo praktik\u0105, \u012fskaitant didesn\u0117s apimties med\u017eiag\u0173 pad\u0117jim\u0105 ant mink\u0161t\u0173 pagrind\u0173 prie\u0161 \u012fdedant jas \u012f tigl\u012f ir automatin\u0117s \u012fkrovimo sistemos su j\u0117gos kontrol\u0117s galimyb\u0117mis naudojim\u0105.<\/p>\n
Sic tigliai pasi\u017eymi puikiu cheminiu atsparumu lydant metalus ir lydinius su auk\u0161tomis virimo temperat\u016bromis, pvz., turin\u010dius didel\u012f vario kiek\u012f. D\u0117l savo inerti\u0161kumo ir ilgaam\u017ei\u0161kumo jie taip pat tinka stiklo ir keramikos med\u017eiagoms apdirbti; d\u0117l inerti\u0161kumo stikl\u0105 ir keramik\u0105 apdirbti lengviau, nes juose n\u0117ra metalini\u0173 ter\u0161al\u0173, pavyzd\u017eiui, r\u016bg\u0161\u010di\u0173 ar \u0161arm\u0173; be to, jie gerai atspar\u016bs korozijai ir oksidacijai.<\/p>\n
Renkantis tigl\u012f lydymo procesams, labai svarbu atsi\u017evelgti \u012f med\u017eiagas ir s\u0105lygas. J\u016bs\u0173 tiek\u0117jas tur\u0117t\u0173 tur\u0117ti daug \u017eini\u0173 apie tigli\u0173 konstrukcijas, kad pad\u0117t\u0173 suderinti konkre\u010dias lydalo savybes su konkre\u010diomis tigli\u0173 konstrukcijomis. Be to, norint i\u0161vengti tiglio sugadinimo naudojimo metu, pavyzd\u017eiui, \u012f j\u012f \u012fmetus sunkius luitus ar liejinius, jo konstrukcija gali suskilti arba \u012ftr\u016bkti, o tai gerokai sutrumpint\u0173 jo tarnavimo laik\u0105; norint tai padaryti saugiai, labai svarbu laikytis geros \u012fkrovimo praktikos, pavyzd\u017eiui, i\u0161 prad\u017ei\u0173 \u012f tigl\u012f krauti lengvas med\u017eiagas, o tik po to ant amortizuojan\u010di\u0173 pagrind\u0173 d\u0117ti sunkesnes med\u017eiagas ir tik tada palaipsniui pilti sunkesnius gaminius.<\/p>\n
I\u0161ankstinis tigli\u0173 kaitinimas prie\u0161 kiekvien\u0105 lydym\u0105 pad\u0117s i\u0161vengti terminio \u0161oko ir strukt\u016bros pa\u017eeidim\u0173, nesvarbu, ar tai b\u016bt\u0173 automatin\u0117 kaitinimo sistema su programuojamu valdikliu, ar tiesiog i\u0161ankstinis kaitinimas kar\u0161tais oro ar duj\u0173 d\u016b\u017eiais prie\u0161 kiekvien\u0105 naudojim\u0105. Taip jie pasieks maksimali\u0105 darbin\u0119 temperat\u016br\u0105 ir neperkais.<\/p>\n
Silicio karbido grafito tiglio atsparumas kar\u0161\u010diui, kaip ir atsparumas chemin\u0117ms med\u017eiagoms, priklauso nuo to, kokiems metalams ir lydiniams lydyti ir laikyti jis naudojamas. Be to, nuo krosnies tipo ir galingumo priklauso jo naudojimo trukm\u0117.<\/p>\n
Kad tiglis b\u016bt\u0173 kuo ma\u017eiau pa\u017eeistas, geriausia lydymo praktika yra tinkamas \u012fkrovimas; tai rei\u0161kia, kad luitai ir liejiniai atsargiai metami \u012f tigl\u012f, o ne sandariai u\u017ekem\u0161ami. Taip suma\u017einsite fizinius pa\u017eeidimus, pavyzd\u017eiui, \u012fskilimus ir \u012ftr\u016bkimus. D\u0117l nepakankamo i\u0161lydyto metalo mai\u0161ymo taip pat gali kilti problem\u0173, kaip ir d\u0117l per didelio fliuso kiekio arba per greito \u017eemos kokyb\u0117s \u0161lak\u0173 prid\u0117jimo \u012f tigl\u012f.<\/p>\n
Tiglio eksploatavimo pabaigos po\u017eymiai yra ploni \u012ftr\u016bkimai ant jo sieneli\u0173 arba \u012fdubimai jo pavir\u0161iuje; kiti po\u017eymiai - l\u0117tesnis lydymosi greitis arba korozijos po\u017eymiai ant paties tiglio.<\/p>\n
sic tigliai yra populiarus pasirinkimas laboratorijose ir mokslini\u0173 tyrim\u0173 \u012fstaigose d\u0117l ma\u017eo atsparumo \u0161iluminiams sm\u016bgiams, didel\u0117s temperat\u016bros tolerancijos ir ilgaam\u017ei\u0161kumo. \u0160ie tigliai yra \u012fvairi\u0173 form\u0173, dyd\u017ei\u0173 ir med\u017eiag\u0173, su pilstomaisiais snapeliais ir (arba) pirometrin\u0117mis ki\u0161en\u0117mis, kad b\u016bt\u0173 galima lengvai steb\u0117ti temperat\u016bros nustatymus, tod\u0117l jie tapo geriausiu pasirinkimu lydant spalvotuosius metalus \u012fvairiose krosnyse, pvz., k\u016brenamose kuru, elektrin\u0117se var\u017ein\u0117se ar indukcin\u0117se krosnyse.<\/p>\n
Sic tigli\u0173 ilgaam\u017ei\u0161kumas priklauso nuo j\u0173 konstrukcijos med\u017eiagos ir geb\u0117jimo atlaikyti chemin\u0119 erozij\u0105 bei staigius temperat\u016bros poky\u010dius. Aliuminio oksido tigliai yra labai patvar\u016bs cheminei erozijai, o j\u0173 kaina yra prieinama; be to, jie populiar\u016bs d\u0117l atsparumo terminiams sm\u016bgiams. Be to, d\u0117l j\u0173 vidutin\u0117s kainos juos lengva reformuoti - to negali pasi\u016blyti aliuminio oksidas.<\/p>\n
Silicio karbido grafito tigliai yra puikus pasirinkimas liejyboje d\u0117l j\u0173 didelio atsparumo auk\u0161tai temperat\u016brai ir cheminei erozijai. Naudojami metal\u0173 ir lydini\u0173 lydymui prie\u0161 juos i\u0161lydant, d\u0117l ma\u017eo j\u0173 dr\u0117kinamumo i\u0161lydyti metalai ir lydiniai neu\u017eter\u0161iami, o d\u0117l j\u0173 i\u0161skirtinio \u0161ilumos laidumo taupoma energija, kartu ma\u017e\u0117ja i\u0161metam\u0173 ter\u0161al\u0173 kiekis ir saugoma aplinka.<\/p>\n
Ilgaam\u017ei\u0161kumas ypa\u010d svarbus, kai reikia da\u017enai pilti ir papildyti degal\u0173 atsargas. Tigliai, sukurti taip, kad atlaikyt\u0173 tokias operacijas, prailgina savo tarnavimo laik\u0105 ir suma\u017eina laiko s\u0105naudas juos valant po kiekvieno naudojimo.<\/p>\n
Norint u\u017etikrinti ilgalaik\u0119 s\u0117km\u0119 naudojant tigl\u012f, reikia glaudaus metalo lydymo \u012fmon\u0117s ir tiek\u0117jo bendradarbiavimo, kad b\u016bt\u0173 galima suderinti savybes su eksploatavimo s\u0105lygomis. Atlikite lydom\u0173 metal\u0173 ir lydini\u0173 inventorizacij\u0105; glaud\u017eiai bendradarbiaukite su tiek\u0117ju, kad pasirinktum\u0117te ideal\u0173, visus reikalavimus atitinkant\u012f tigl\u012f; \u0161i partneryst\u0117 u\u017etikrina saug\u0105, optimal\u0173 veikim\u0105 ir ilgalaik\u012f tigli\u0173 tinkamum\u0105 naudoti.<\/p>\n
