Ungayisebenzisa njani i-silicon carbide crucible ekucoceni isinyithi?

Isizathu sokuba kuthenii-silicon carbide crucibleIxabiso layo elisebenzayo liphezulu kakhulu ngenxa yeempawu zayo ezifanayo.iipropati zekhemikhali ezizinzileyo, ukuhanjiswa kobushushu obuphezulu, i-coefficient yokwandisa ubushushu obuphantsikunye nokumelana nokuguguleka okuhle. Ukongeza ekusetyenzisweni njenge-abrasive, ikwanazo nezinye izinto ezininzi ezisetyenziswayo. Umzekelo, ukugquma i-silicon carbide powder eludongeni lwangaphakathi lwe-turbine impeller okanye i-cylinder block ngenkqubo ekhethekileyo kunokuphucula ukumelana nokuguguleka kwayo kwaye kwandise ubomi bayo benkonzo ngokuphindwe ka-1 ukuya ku-2; Izinto ezisemgangathweni ophezulu ezimelana nomlilo ezenziwe ngayo zinezibonelelo zokubaukumelana nobushushu, umthamo omncinci,ubunzima obuphantsi, amandla aphezulu kunye nesiphumo esihle sokonga amandla. I-silicon carbide yodidi oluphantsi (equlethe malunga ne-85% SiC) yi-deoxidizer egqwesileyo. Ingakhawulezisa isantya sokwenza intsimbi, incedise ulawulo lwekhemikhali kwaye iphucule umgangatho wentsimbi.
Ekusetyenzisweni kwe-silicon carbide crucible, indima yokuzivocavoca kunye nokucoca isinyithi iqinisekiswe kakhulu ngabasebenzisi. Kwishishini lokusetyenziswa kwe-crucible, indawo ye-silicon carbide crucible inokuthiwa ibaluleke kakhulu.
Ngenxa yokuba i-silicon carbide yenziwe ngeisanti ye-quartz, i-petroleum coke, uthuli lwesarha kunye nezinye izinto ngokusebenzisa umthambo wobushushu obuphezulu kwisithando sokumelana, i-silicon carbide crucible inamandlaukumelana nomliloubuchule kwimisebenzi yokuzilolonga ngesinyithi, ngoko ke kwanele ukuqinisekisa ubushushu obuphezulu obufunekayo kumthambo, ukunciphisa kakhulu ubunzima bokucocwa kwesinyithi, ukonga iindleko kunye nokuphucula ukusebenza kakuhle kokusetyenziswa.
