Ngokumalunga nokupholisa kwe imibhobho yokuhlobisa insimbi engenasici kwinkqubo yokuvelisa, iimfuno zobugcisa ezisetyenziswa apha ziphezulu kakhulu.Ngokomzekelo, ukuba ukulawulwa kweqondo lokushisa akulungile, okubangelwa ukuveliswa kwe-316 yoxinzelelo lwe-thermal kunye noxinzelelo lwesakhiwo, umbhobho wensimbi unokuqhekeka okanye uphazamise.Okulandelayo, IHangao Tech (i-SEKO Machinery) iya kwazisa ngokweenkcukacha ulwazi lokuvelisa imibhobho yentsimbi yokuhombisa yokupholisa:
Ngenxa yokwabiwa kwakhona koxinzelelo lwangaphakathi ngexesha lokucutshungulwa, ityhubhu yentsimbi yokuhlobisa iya kuphazamiseka, kwaye ukuchaneka kokucubungula akunakuqinisekiswa.Ukongezelela, ukuphatha iinxalenye ezinkulu kuxhomekeke kuxinzelelo olushiyekileyo.Zonke ezi ityhubhu zokuhombisa intsimbi engenastainless kufuneka ziyeke ukukhululeka koxinzelelo emva komatshini orhabaxa.Ukususwa kwe-annealing yoxinzelelo lwangaphakathi ngokuqhelekileyo kukuhlobisa ityhubhu yensimbi engenasici.Kwi-500-550 ° C, yayisetyenziswe ngaphambili kwiqondo lokushisa kwe-50 ukuya kwi-100 imizuzu, i-3 ukuya kwiiyure ze-5 okanye ngaphezulu (kuxhomekeke kwinani leziko ezifakiweyo) ukugcina uxinzelelo lwangaphakathi ixesha elide.Kubizwa ngokuba ukuguga kwendalo, kodwa le ndlela inde kakhulu kwaye ayisoloko isetyenziswa.
Xa ityhubhu yokuhombisa yensimbi engenastainless ipholile, umphezulu kunye nezinye iindawo ezibhityileyo zivame ukuvelisa ulwakhiwo olumhlophe, oluqinileyo, olumhlophe.Ke ngoko, iityhubhu eziqhelekileyo zokuhombisa intsimbi engenasici kufuneka zifakwe okanye zilungelelaniswe ukuphelisa iziphene zokuphosa.Iqondo lobushushu le-annealing okanye lesiqhelo liphakathi kwama-850 kunye nama-950°C.Iqondo lokushisa ligcinwa kwiiyure ezingama-1-2, i-cementite ihlanganiswe kwigraphite kunye ne-austenite (inqanaba lokuqala le-graphitization).Yethu i-intanethi eqhubekayo eqaqambileyo yomlilo yokutshisa inokukunceda.Ayifuni ukufudumeza kwangaphambili, inokufikelela kubushushu obufanelekileyo bokutshisa ngaphakathi kwemizuzwana eyi-10 emva kokuqala.
Ngaphezu koko, idibaniswe nenkqubo ye-PLC, unokubona ngokuthe ngqo idatha yexesha langempela, ukubeka iliso ngexesha langempela loxinzelelo lomoya, ukuhamba kwamanzi, ukushisa okusebenzayo, isantya.Ngexesha lokupholisa okulandelayo kwesithando somlilo, i-cementite yesibini kunye ne-eutectoid cementite ziya kuhlanganiswa kwigraphite (oko kukuthi, inqanaba lesibini legraphitization).Ekugqibeleni, i-perlite yongezwa kwi-ferrite okanye i-ferrite matrix ukunciphisa ubunzima kunye namandla okuphosa.Ukongeza, inkqubo ye-cementing yi-850-950 ° C, kodwa i-cementite kwinkqubo yokulinganisa, enokunciphisa ixesha lokupholisa lobunzima betyhubhu yensimbi engenasici, inokufumana amandla athile kunye nobunzima be-matrix ye-pearlite kunye. .
