Ukuthuthukiswa kwenqubo yokwelapha ukushisa yensimbi yeketanga eliphakeme engu-23MnNiMoCr54
Ukwelashwa ngokushisainquma ikhwalithi kanye nokusebenza kwensimbi yochungechunge oluyindilinga, ngakho-ke inqubo yokwelapha ukushisa enengqondo nephumelelayo iyindlela ephumelelayo yokuqinisekisa ukuzinza okuhle kwensimbi yochungechunge oluphezulu.
Inqubo yokwelashwa ngokushisa kwensimbi ye-chain ye-23MnNiMoCr54 ephezulu
Indlela yokushisa yokungenisa imvamisa ephakathi inezici zesivinini sokushisa esisheshayo kanye ne-oxidation encane, engagcini nje ngokuhambisana nokukhiqizwa okuluhlaza okwamanje, kodwa futhi ifinyelela izinkomba ezithile zamandla nokuqina kweketanga lensimbi eyindilinga. Inqubo ethile yokwamukela ukwelashwa kokushisa kokungenisa imvamisa ephakathi ukusebenzisa isithando esiqhubekayo sokungenisa imvamisa ephakathi semishini yokushisa enamandla aphezulu kuqala, ukuze kutholakale ukuhlukaniswa kokucima nokushisa kweketanga lensimbi eyindilinga. Izinga lokushisa lokucima nokushisa ngaphambi kokuba iketanga lifakwe emlilweni lilawulwa ngokuqinile ngokulinganisa izinga lokushisa le-infrared. Ngokusebenzisa ukuhlolwa okusebenzayo, kutholakale ukuthi indawo yokupholisa yokucima nokushisa ngamanzi, Izinga lokushisa lamanzi lilawulwa ngaphansi kwama-30 ℃. Amandla okushisa okucima kufanele alawulwe phakathi kwama-25-35kw, ijubane leketanga kufanele lilawulwe ku-8-9hz futhi izinga lokushisa kufanele lilawulwe phakathi kwama-930 ℃ -960 ℃, ukuze ubulukhuni besendlalelo esiqinile kanye neketanga kuhlangabezane nezidingo ezithile zekhwalithi. Amandla okushisa enqubo yokufudumala alawulwa ku-10-20kw futhi izinga lokushisa lilawulwa ku-500 ℃-550 ℃. Ijubane leketanga ligcinwa phakathi kuka-15 no-16Hz.
(1) Esigabeni sokuqala sokwenzauchungechunge lwesixhumanisi sensimbi oluyindilinga, indlela yokwelapha ukushisa iyisithando esikhanyayo, njengesithando somlilo esijikelezayo. Isithando somlilo esijikelezayo sisetshenziselwa ukufudumala. Le ndlela idinga isikhathi eside sokushisa kanye nokusebenza kahle okuphansi, okunye okudinga uchungechunge olude lokudonsa. Kuyo yonke inqubo yokushisa yeketanga, ngenxa yezinga eliphezulu lokushiswa komhlaba, kunzima ukuthola izinhlamvu ze-austenite ezinhle kakhulu, okugcina kuholele ekhwalithini ejwayelekile yeketanga lensimbi eliyindilinga elikhiqizwa ngaleso sikhathi. Ngokuthuthuka okuqhubekayo kobuchwepheshe bokwelapha ukushisa, indlela yokushisa ephakathi nendawo eyathuthukiswa esigabeni sakamuva isetshenziswa kabanzi, futhi ikhwalithi yokwelapha ukushisa yeketanga lensimbi eliyindilinga ithuthukisiwe kakhulu.
(2) Ubuchwepheshe bokushisisa iketanga, ukusetshenziswa kokuqala kokushisa okufanayo, ugesi. Ukuthuthukiswa kokuzinza kakhulu ukufudumala okuphakathi nendawo kanye nokushisa okufanayo kanye nokushisa okufanayo. Lokhu okubizwa ngokuthi ukushisa okufanayo kuwukucabangela ukuthi ubunzima bengxenye ngayinye yesixhumanisi seketanga buyafana ngemva kokushisa, kodwa isixhumanisi seketanga senziwe ngokushisisa. Uma izinga lokushisa lokushisa liphansi kakhulu, ijoyinti lokushisisa lilula ukuphuka, kanti ubunzima besixhumanisi seketanga buphakeme, ukungqubuzana phakathi kwengalo eqondile kanye nokushintsha okuphakathi kwe-conveyor nakho kulula kakhulu ukukhiqiza imifantu. Uma izinga lokushisa lokushisa liphansi, ukuqina kweketanga nakho kungancishiswa. Ukushisa okuhlukile kusebenzisa ukushisa kwe-induction, okulungele kakhulu izimo zokushisa zeketanga, okungukuthi, ingxenye ephezulu yehlombe leketanga inobunzima obukhulu kanye nokumelana nokuguguleka, kanti ingalo eqondile inobunzima obuphansi kanye nokuqina okuhle. Le ndlela yokwelapha ukushisa ingathuthukisa kakhulu ikhwalithi yeketanga.
