Iintsimbi zegraphiteziyaziwa ngokugqwesa kwe-thermal conductivity kunye nokumelana nobushushu obuphezulu. I-coefficient yabo ephantsi yokwandiswa kwe-thermal ivumela ukuba bamelane nokufudumeza ngokukhawuleza kunye nokupholisa. Bakwabonisa ukuxhathisa okuqinileyo kwi-asidi kunye ne-alkaline, ebonisa ukuzinza kweekhemikhali okugqwesileyo. Kwi-metallurgy, casting, machine, industry chemicals and other industry sectors, it is widely used in smelting of alloy tool metal, non-ferrous metals and their alloys, kwaye ineenzuzo ezilungileyo zobugcisa kunye nezoqoqosho. Umvelisi olandelayo weemveliso zegraphite zeHaoyu uya kwazisa amanyathelo athile okhuseleko xa usebenzisa i-graphite crucible. Izilumkiso: Bamba ngononophelo ngexesha lokuhamba ukuze ugweme umonakalo kwi-coating yomhlaba kwaye ugweme ukuqengqeleka. Gcina kwindawo eyomileyo ukukhusela ukufuma. Xa isetyenziswe kwi-oven ye-coke, i-bottom kufuneka ibe yisiseko se-crucible kunye nobubanzi obuncinane kunobubanzi obuphantsi be-crucible ukunika inkxaso efanelekileyo. Xa ulayishwa kwisithando somlilo, i-crucible ayifanele ifakwe, kwaye ukuvuleka okuphezulu akufanele kube phezulu kunomlomo wesithando somlilo. Ukuba izitena ezixhasayo zisetyenziselwa phakathi kwe-crucible top opening kunye nodonga lwesithando somlilo, izitena kufuneka zibe phezulu kunokuvulwa kwe-crucible. Ubunzima bekhava yesithando somlilo kufuneka bube eludongeni lwesithando somlilo. Ubungakanani be-coke esetyenzisiweyo kufuneka bube buncinci kunesithuba phakathi kodonga lwesithando somlilo kunye ne-crucible. Kufuneka bongezwe ngokuwa ngokukhululekileyo ukusuka ekuphakameni ubuncinane be-5 cm kwaye akufanele bafakwe. Ngaphambi kokusetyenziswa, i-crucible kufuneka ifudunyezwe ukusuka kwiqondo lokushisa ukuya kwi-200 ° C kwiiyure ezingama-1-1.5 (ngokukodwa xa kushushu okokuqala, i-crucible kufuneka iguqulwe ngokuqhubekayo ukuqinisekisa ukuba ngaphakathi nangaphandle kwe-crucible ifudumala ngokulinganayo, kwaye ubushushu obuphezulu bokuphakama yi-100 ° C). Emva kokupholisa kancinci kwaye ususe umphunga, qhubeka ufudumeza). Emva koko yafudunyezwa malunga ne-800 ° C ngeyure enye. Ixesha lokubhaka akufanele libe lide kakhulu. (Ukuba ukufudumeza okungafanelekanga kubangela ukukrazula kunye nokuqhekeka, akusiyo ingxaki yomgangatho, kwaye inkampani yethu ayinaxanduva lokubuyisela.) Iindonga zesithando somlilo kufuneka zigcinwe zikhuselekile ukukhusela ukuphambuka komlilo. Ukuba isitshisi sisetyenziselwa ukufudumeza, ilangatye akufanele litshizwe ngokuthe ngqo kwi-crucible, kodwa kwisiseko se-crucible. Izithawuni ezifanelekileyo zokubethelwa kufuneka zisetyenziselwe ukuphakamisa nokulayisha. Xa ulayisha isinyithi, umgca we-scrap kufuneka usasazwe ngaphantsi ngaphambi kokufaka ingot yensimbi. Kodwa isinyithi akufanele sibekwe kakhulu okanye kwinqanaba njengoko oku kunokubangela ukuba i-crucible iqhekeke ngenxa yokwandiswa kwesinyithi. Ukunyibilika okuqhubekayo kunciphisa ixesha phakathi kwee-crucibles. Ukuba ukusetyenziswa kwe-crucible kuphazamisekile, i-liquid eseleyo kufuneka ikhutshwe ukuze igweme ukuphuka xa iphinda iqaliswe. Ngethuba lenkqubo yokunyibilika, isixa se-ejenti yokucoca kufuneka ilawulwe ngokungqongqo. Ukusetyenziswa ngokugqithiseleyo kuya kunciphisa ubomi be-crucible. I-slag eqokelelweyo kufuneka isuswe rhoqo ukuphepha ukuguqula imilo kunye nomthamo we-crucible. Ukwakhiwa kwe-slag ngokugqithisileyo kunokubangela ukuba umphezulu udumbe kwaye uqhekeke. Ngokulandela ezi zilumkiso, unokuqinisekisa umsebenzi ofanelekileyo kunye nobomi be-graphite crucible yakho.
