Ukusetyenziswa kunye neempawu ze-graphite sagger crucible

I-Crucible ingasetyenziselwa ukufudumeza ngamandla inani elikhulu leekristale. I-Crucible ingahlulwahlulwa ibeisixhobo sokubethela igrafayithikwayeisixhobo sokuqhumisa se-quartz. I-Graphite crucible inomoya ofanelekileyo wokushisa kunye nokumelana nobushushu obuphezulu; Xa isetyenziswa kubushushu obuphezulu, i-coefficient yokwandiswa kobushushu incinci kakhulu. Inokumelana okunamandla kobushushu obugqithisileyo kunye nokubanda. Ayimelani ne-asidi enamandla kunye ne-alkali. Ifanelekile ukufudumeza iintlobo ngeentlobo zolwelo; Ukongeza kwi-chemistry, ii-graphite crucibles zisetyenziswa kakhulu kwi-metallurgy, i-casting, oomatshini, kushishino lweekhemikhali nakwamanye amasebe; I-graphite crucible yenziwe ngezinto ze-graphite zendalo, ezigcina ukufudumeza okukhethekileyo komlilo we-graphite. I-graphite crucible isetyenziselwa kakhulu ukunyibilikisa iintsimbi ezingenayo i-ferrous ezifana nobhedu, i-aluminium kunye ne-alloy. Kukho iimpawu ezingenakubalwa ze-graphite crucible ngokwayo. Apha siza kudwelisa ngokufutshane enye okanye ezimbini zakho.
1. Ungcoliseko oluncinci, kuba amandla acocekileyo afana negesi yendalo okanye igesi enyibilikisiweyo angasetyenziswa njengepetroli kwaye ungcoliseko oluncinci lungasetyenziswa.
2. Ukusetyenziswa kwamandla aphantsi, kuba isixhobo sokucoca igrafiti sinocwangciso olufanelekileyo, isakhiwo esiphucukileyo kunye nezixhobo ezintsha. Emva kovavanyo, ukusetyenziswa kwamandla kuphantsi kunokohlobo olufanayo lwesithando somlilo.
Isithando somlilo esinobuqhophololo obuphezulu, i-graphite crucible, sisetyenziselwa ukunyibilikisa igolide, isilivere kunye neentsimbi ezinqabileyo.Izinto zokubethela zeseramikhiZisetyenziswa kakhulu kwiilabhoratri kunye nokunyibilikisa iplatinum, igolide kunye neentsimbi ezinqabileyo. Ngaba i-graphite crucible ingasetyenziswa kubushushu obuphezulu be-2000 ℃ phantsi kwemeko yomoya? Ngaba iya kubola kwaye i-oxidize ngamandla? Ngaba iya kuyi-carburize isinyithi esinyibilikisiweyo? Eyona nto ibalulekileyo kukuba i-carburize iyabulala. Kwiimeko eziqhelekileyo, inokufikelela kuma-2000 degrees emoyeni, kodwa iya kuyi-oxidize ngokukhawuleza. Ingxaki ye-metal carburization kufuneka ikho. Ngoku kukho i-anti carburize coating ekhethekileyo kwimarike, ekuthiwa inefuthe elihle.
