Umshini ophazamisayo obandayo wamukela i-disc kanye nezinto ze-bar eqondile futhi USEBENZISA isimiso sokucasula kwesibili ukukhiqiza ikhanda elihlukahlukene, ikhanda elicwilisiwe, ikhanda le-semi-countersunk, isokhethi le-hexagon namanye amabhawodi ekhanda angajwayelekile kanye nezingxenye zemishini.
Ngakho-ke yiziphi izidingo zomshini wokubanda obandayo wezinto zokucubungula?
1.Ukwakheka kwamakhemikhali kanye nezakhiwo zemishini zezinto zokusetshenziswa zesihloko esibandayo somshini womgodi obandayo kuzohlangabezana nezindinganiso ezifanele.
2. Umkhiqizi womshini wesihloko esibandayo onezikhundla eziningi uchaze ukuthi impahla yaphathwa nge-spheroidization annealing, futhi ukwakheka kwe-metallographic kwento kwakuyindilinga ye-pearlite yebanga lesi-4-6.
3.ubulukhuni bezinto zokusetshenziswa, ukuze kuncishiswe ukuthambekela kokuqhekeka kwempahla ngangokunokwenzeka, ukuthuthukisa impilo yenkonzo yesikhunta futhi kudinga ukuthi impahla yokudweba ebandayo inobunzima obuphansi kakhulu ngangokunokwenzeka, ukuze kuthuthukiswe ipulasitiki.Ubulukhuni bezinto ezingavuthiwe ngokuvamile kudingeka bube phakathi kwe-HB110 kanye ne-170(HRB62-88).
4.umdwebo obandayo wokunemba kwe-intshi egcwele kufanele usekelwe ezidingweni ezithile zomkhiqizo kanye nesimo senqubo, ukukhuluma ngokuvamile, ukuze kuncishiswe ububanzi kanye nobukhulu bezidingo zokunemba ezimbalwa eziphansi.
5. Umkhiqizi womshini okhungathekisayo obandayo uchaza ukuthi izinga eliphezulu lezinto zokudweba ezibandayo lidinga ukuthi ifilimu yokugcoba kufanele ibe mnyama futhi icwebezele, futhi indawo engaphezulu akufanele imakwe ngemihuzuko, ukugoqa, imifantu, ukugqwala, izikali, imigodi, ukugoba nezinye iziphambeko.
6.Ubukhulu obuphelele bongqimba lwe-decarburization endaweni eyirediyasi yezinto zokudweba ezibandayo akumele budlule u-1-1.5% wobubanzi bempahla eluhlaza (isimo esithile sincike ezidingweni zomkhiqizi ngamunye).
7.ukuze kuqinisekiswe ikhwalithi yokwakheka okubandayo okunqunyiwe, izinto zokudweba ezibandayo ziyadingeka ukuze zibe nendawo eqinile, kodwa inhliziyo iyisimo esithambile.
8. izinto zokudweba ezibandayo kufanele zenziwe ukuhlolwa kwekhefu elibandayo, ngesikhathi esifanayo, impahla kufanele ibe kancane ezwela ukuqina okubandayo, ukuze kuncishiswe inqubo yokuguqulwa, ngenxa yokuqina kokuqina kokuqina kokumelana kwanda.
