Munzvimbo yeimwe crystal furnace tekinoroji, kunyatsoita uye kurongeka kwekutonga kwekupisa ndiko kwakakosha. Kuwana yakaringana tembiricha kufanana uye kugadzikana kwakakosha mukukura emhando yepamusoro makristasi mamwe. Kugadzirisa matambudziko aya,graphite heatersdzakabuda semhinduro inoshamisa, nekuda kweiyo yakasarudzika yekupisa conductivity. Muchinyorwa chino, tichaongorora kukosha kweiyo graphite heaters uye basa ravo mundima yekupisa yemafuta ekristaro imwe chete.
Graphite, imhando yekabhoni, ine yakasarudzika zvivakwa zvinoita kuti ive chinhu chakanakira chepamusoro-tembiricha application. Imwe midziyo yakadaro ndiyo yakanakisa yekupisa conductivity. Graphite ine yakanyanya kupisa yekupisa conductivity, ichiibvumira kukurumidza uye nemazvo kutamisa kupisa mukati mechimiro chayo. Iyi yakasarudzika hunhu inoita kuti ive sarudzo yakanaka kunekudziyisa zvinhumune imwe crystal furnaces.
Iyo yekupisa conductivity yegraphite inogona kuverengerwa kune yayo yakasarudzika crystal chimiro. Graphite ine zvikamu zvekabhoni maatomu akarongwa mune hexagonal lattice. Mukati mechikamu chimwe nechimwe, maatomu ekabhoni akasungwa zvakasimba, achigadzira mabhondi akasimba akasimba. Zvisinei, kubatana pakati pezvikamu hakuna simba, zvichiita kuti pave nekugadzirwa kwemavara ane maerekitironi akasununguka anogona kufamba nyore nyore. Aya maerekitironi emahara anobatsira kune graphite yakakwirira yemagetsi uye yekupisa conductivity.
Mumunda wekupisa wemafuta ekristaro imwe chete,graphite heaterskuita basa rakakosha mukuwana kudziyisa chaiko uye kwakafanana. Nekuitisa kupisa zvakanaka, vanobatsira kuchengetedza tembiricha inodiwa mukati mekukura kwekristaro. Iyo yakanakisa yekupisa conductivity yegraphite inova nechokwadi chekuti kupisa kunogovaniswa zvakaenzana padenga rehita, kuderedza tembiricha yekupisa uye hotspots. Kufanana uku kwakakosha pakudzorwa uye kunoenderana kukura kwekristaro imwechete, iyo inokanganisa zvakananga kunaka kwavo uye zvivakwa.
Uyezve, iyo yakakwirira yekupisa conductivity yegraphite heatersinobvumira kukurumidza kupisa uye kutonhora kutenderera, kuderedza nguva yekugadzirisa mukukura kwekristaro imwe chete. Iyo inoshanda yekupisa kupisa inopihwa negraphite inoita kuti choto chisvike painoda tembiricha nekukurumidza, ichiwedzera chibereko mukugadzirwa kwekristaro. Pamusoro pezvo, kugona kutonhora nekukurumidza mushure mekukura kwekuita kunofambisa kukurumidza kubviswa kwekristaro uye kuderedza iyo yakazara nguva yekugadzira.
Graphite heatersvanoratidzawo kugadzikana kwakanaka kwekupisa, zvichiita kuti vakwanise kutsungirira tembiricha yakanyanyisa inowanikwa munzvimbo imwechete yekristaro yevira. Vanogona kushanda patembiricha dzakakwirira pasina kushatisa kwakanyanya kana kukanganisa. Uku kugadzikana kwekupisa kunovimbisa hupenyu hurefu uye kuvimbika kwezvidziviriro, kuderedza zvinodiwa zvekuchengetedza uye kuderera mukukura kwekristaro.
Imwe mukana wegraphite heatersiko kuenderana kwavo ne vacuum kana inodzorwa mamiriro ekunze anowanzo shandiswa mukukura kwekristaro imwe chete. Graphite ikemikari inert uye haibatike nemagasi mazhinji, ichiibvumira kuchengetedza zvinhu zvayo zvekupisa munzvimbo dzakasiyana siyana. Izvi zvakasiyana-siyana zvinogadziragraphite heatersinokodzera kuwanda kwemaitiro ekukura kwekristaro, kusanganisira Czochralski, Bridgman, uye nzira dzinoyangarara dzenzvimbo.
Mukupedzisa, iyo yakasarudzika thermal conductivity yegraphite heatersinoita kuti ive yakakosha mumunda wekupisa wemafuta ekristaro imwe chete. Kugona kwavo kutamisa kupisa zvakanaka uye kuchengetedza tembiricha yakafanana kwakakosha pakukura kunodzorwa kwemhando yepamusoro yemakristasi. Graphite heaters inogonesa kukurumidza kupisa uye kutonhora kutenderera, inosimudzira chibereko, uye inopa yakanakisa kugadzikana kwekupisa munzvimbo dzakanyanyisa. Sezvo kudiwa kwepamusoro-kushanda kwekristaro imwe chete kuri kuramba kuchikura, kukosha kwemagraphite heaters mukufambisa mberi tekinoroji yekukura kwekristaro haigone kuwedzeredzwa.
