IiPropati zoKuxhathisa ukonakala kweGraphite Crucibles kuShishino lweMetallurgical

Intshayelelo

Kwishishini le-metallurgical, ukusetyenziswa kwezinto ezisemgangathweni kubaluleke kakhulu ukuze kuqinisekiswe ukuveliswa okusebenzayo nokuthembekileyo kwesinyithi kunye ne-alloys. Phakathi kwezixhobo ezahlukeneyo ezisetyenzisiweyo, ii-graphite crucibles ziye zafumana ukuthandwa okuphawulekayo ngenxa yeempawu zazo zokumelana nokubola. Eli nqaku liphonononga iimpawu zokuxhathisa ukubola kweiicrucibles zegraphitekunye nendima yabo eyimfuneko kwiinkqubo ze-metallurgical.

Ukunyangwa koMhlwa kweIiCrucibles zeGraphite

I-graphite, ifom yekhabhoni, ibonisa ukuchasana okuphawulekayo ekuhlaselweni kweekhemikhali kunye namaqondo okushisa aphezulu, okwenza kube yinto efanelekileyo yezinto eziphathekayo kwi-metallurgical industry. Ukuxhatshazwa kwe-corrosion ye-graphite crucibles kubangelwa iimpawu ezizodwa zegraphite ngokwayo. Igraphite inendalo engasebenziyo, nto leyo iyithintelayo ekubeni isabele kuninzi lweeasidi, iialkali, kunye nezinye izinto eziyingozi ezidibana nazo ngexesha lokunyibilika kwesinyithi kunye nokuveliswa kwealloyi.

▪ Ukumelana neAcidi:

Iintsimbi zegraphitebonisa ukuxhathisa okugqwesileyo kwiindawo ezineasidi. Bayakwazi ukumelana nemiphumo eyingozi ye-asidi efana ne-sulfuric acid, i-hydrochloric acid, kunye ne-nitric acid. Lo mgangatho ubalulekile kwiinkqubo ezibandakanya ukuphatha iiasidi, ezifana nokuveliswa kweentsimbi ezithile kunye neeoksidi zetsimbi.

▪ Ukumelana neAlkali:

Ukongeza kwi-acids,iicrucibles zegraphitebonisa ukuxhathisa kwi-alkalis. Izinto zealkaline, ezifana nesodium hydroxide kunye nepotassium hydroxide, ziqhele ukusetyenziswa kwiinkqubo ezahlukeneyo zesinyithi.Iintsimbi zegraphitehlala ungachaphazeleki ngala ma-alkali, uqinisekisa ukuthembeka kunye nobude be-crucible ngexesha leenkqubo ezinjalo.

▪ Ukumelana ne-Oxidation:

Igraphite inokumelana ne-oxidation ebalaseleyo, nokuba kubushushu obuphezulu. Xa iphantsi kobushushu obugqithisileyo, i<em>graphite yenza umaleko okhuselayo we<em>graphite oxide kumphezulu wayo, osebenza njengomqobo ochasene ne<em>oxidation eyongezelelekileyo. Lo mhlaba uluncedo kakhulu kwizicelo apho iziphambuka zisesichengeni se-oxidizing atmosphere, njengokunyibilikiswa nokusulungekiswa kwesinyithi.

Ukunyangwa kweThermal Shock: Enye inkalo ebalulekileyo yeiicrucibles zegraphitekukuxhathisa kwabo ukothuka kwe-thermal. I-graphite ine-conductivity ephezulu ye-thermal kunye ne-coefficient ephantsi yokwandiswa kwe-thermal, eyenza ukuba ikwazi ukumelana nokutshintsha kweqondo lokushisa ngokukhawuleza ngaphandle kokuqhekeka okanye ukuphuka. Oku kuxhathisa ukothuka kwe-thermal kubalulekile kwiinkqubo ezibandakanya ukufudumeza okuphindaphindiweyo kunye nemijikelo yokupholisa, njengokuphosa isinyithi kunye nokuveliswa kwe-alloy.

Izinto eziluncedo zeGraphite Crucibles

Iipropathi zokuxhathisa ukubola kwe-graphite crucibles zibonelela ngeenzuzo ezininzi kwishishini lesinyithi:

▪ Ubomi Obude:

I-Graphite crucibles inobomi obude xa kuthelekiswa ne-crucibles yendabuko eyenziwe ngezinto ezifana nodongwe okanye i-ceramic ngenxa yokumelana kwabo okuphezulu kwi-corrosion kunye ne-thermal shock.

▪ Ukuphuculwa koMgangatho weMveliso:

Ubume obungaguqukiyo be-graphite crucibles buqinisekisa ukuba isinyithi esinyibilikisiweyo okanye i-alloy ihlala ingahlambulukanga, ekhokelela kwiimveliso eziphezulu eziphezulu.

▪ Ukusebenza kakuhle kwamandla:

Iicrucibles zegraphite zine-conductivity efanelekileyo ye-thermal, eyenza ukuhanjiswa kobushushu okusebenzayo, ukuhanjiswa kobushushu obufanayo, kunye nokunciphisa ukusetyenziswa kwamandla ngexesha lenkqubo yokunyibilika.

Iindleko-Ukusebenza: Nangona ekuqaleni zibiza kakhulu kunezinye izinto ezinqamlekileyo, i-graphite crucibles 'ubomi obude kunye nokusebenza okuphezulu kubenza ukuba bakhethe iindleko ezisebenzayo ekuhambeni kwexesha.

Ukuqukumbela

Iicrucibles zegraphite zidlala indima ebalulekileyo kwishishini lesinyithi, libonelela ngeempawu ezikhethekileyo zokuxhathisa ukubola, ukuxhathisa ukothuka kwe-thermal, kunye nokumelana ne-oxidation. Ukukwazi kwabo ukumelana neemeko ezinzima ezidibana nazo ngexesha lokunyibilika kwesinyithi kunye nokuveliswa kwe-alloy kubenza babaluleke kakhulu kwiinkqubo ezahlukeneyo ze-metallurgical. Ngokukhetha i-graphite crucibles, abavelisi banokuqinisekisa umgangatho wemveliso ophuculweyo, ubomi obude be-crucible, ukusebenza kakuhle kwamandla, kunye nokusebenza kakuhle kweendleko. Njengoko i-metallurgical industry iqhubela phambili, i-graphite crucibles iya kuhlala iyinto ethembekileyo kwaye ibalulekileyo ekufuneni ukuveliswa kwesinyithi ngokufanelekileyo kunye nomgangatho ophezulu.
