Imbali yoPhuhliso yeSilicon carbide crucible

Kwintsimi ye-metallurgy, imbali yemveliso ye-Silicon carbide crucible esetyenziselwa ukunyibilikisa izinyithi ezingenayo i-ferrous inokulandelwa emva kwe-1930s. Inkqubo yayo eyinkimbinkimbi ibandakanya ukutyunyuzwa kwezinto eziluhlaza, ukudibanisa, ukujikeleza ngesandla okanye ukwenza umqulu, ukomisa, ukudubula, i-oiling kunye nobungqina bomswakama. Izithako ezisetyenzisiweyo ziquka i-graphite, udongwe, i-pyrophyllite clinker okanye i-high-alumina bauxite clinker, i-monosilica powder okanye i-ferrosilicon powder kunye namanzi, exutywe kwinqanaba elithile. Ngokuhamba kwexesha, i-silicon carbide iye yadityaniswa ukunyusa umgangatho we-thermal conductivity kunye nokuphucula umgangatho. Nangona kunjalo, le ndlela yemveli isebenzisa amandla aphezulu, umjikelo wemveliso omde, kunye nelahleko enkulu kunye nokuguqulwa kwinqanaba lemveliso eligqityiweyo.

Ngokuchaseneyo, eyona nkqubo yanamhlanje iphambili yokwenziwa kwecrucible kukucinezela isostatic. Le teknoloji isebenzisa i-graphite-silicon carbide crucible, kunye ne-phenolic resin, i-tar okanye i-asphalt njenge-agent ebophelelayo, kunye negraphite kunye ne-silicon carbide njengezona zixhobo eziphambili. I-crucible ebangelwayo ine-porosity ephantsi, ubuninzi obuphezulu, ukuthungwa okufanayo kunye nokumelana nokugqwala okuqinileyo. Nangona ezi nzuzo, inkqubo yokutshisa ikhupha umsi onobungozi kunye nothuli, okubangela ukungcoliseka kwendalo.

Ukuveliswa kwemveliso ye-Silicon carbide crucible ibonisa ushishino oluqhubekayo lokufuna ukusebenza kakuhle, umgangatho kunye noxanduva lokusingqongileyo. Njengoko iteknoloji ihambela phambili, kugxilwe ekuphuhliseni iindlela zokunciphisa ukusetyenziswa kwamandla, ukunciphisa imijikelo yemveliso kunye nokunciphisa impembelelo yokusingqongileyo. Abavelisi be-Crucible bahlola izinto ezintsha kunye neenkqubo zokufezekisa ezi njongo, zijolise ekubetheni ukulingana phakathi kwesithethe kunye nesimanje. Njengoko imfuno yokunyibilikiswa kwesinyithi engasebenziyo iqhubeka nokukhula, uphuhliso lwemveliso ye-crucible luya kudlala indima ebalulekileyo ekubumbeni ikamva lesinyithi.
