Uma abantu abaningi bezwa 'izingxenye zamagiya ensimbi', babona into eshayayo, esindayo, futhi ngokusobala, eyisidala. Lowo umbono oyiphutha wokuqala. Iqiniso liwukuthi, ezinhlelweni ezithile zezimboni, akukho lutho olufana nokuncibilika kokudlidliza nokumelana nokugqoka kwento eyenziwe kahle. igiya lensimbi. Iqhinga alikho ekukhetheni insimbi ekhonjiwe, kodwa ekwazini kahle ukuthi isetshenziswa nini futhi kanjani. Ngibone amaphrojekthi amaningi kakhulu azenzakalelayo ensimbi noma i-ductile iron ngenxa nje yokuthi unjiniyela ubengawazi ama-nuances wegrey noma amamaki e-iron ductile for gearing. Akusona isixazululo esilingana nento eyodwa, futhi ukulenza lingalungile kusho ukwehluleka ngaphambi kwesikhathi, umsindo, nesikhathi sokuphumula esibizayo.
Ukukhetha Okubalulekile Akukhona Nje Ngamandla
Asikhulume amamaki. Insimbi empunga, njengeClass 30 noma 35, inalowo mthamo omuhle kakhulu wokudambisa engiwushilo. Kuhle kakhulu ekunciphiseni ukukhala kwegiya emishinini emikhulu, enesivinini esincane—cabanga ngemishini yezimayini noma ama-conveyor asindayo. Kodwa awukwazi ukuthatha umdwebo wegiya lensimbi bese uwuthela ngensimbi empunga. Amandla aqinile kanye nokumelana nomthelela kuphansi. Ngikhumbula iphrojekthi yegiya lengxenye yokomisa yomshini wephepha. Idizayini yokuqala yensimbi empunga yezinga eliphansi iqhubekile nokwakha imifantu emincane empandeni yamazinyo ngemva kwezinyanga ezimbalwa zokulayisha ngomjikelezo. Ukugxila kwengcindezi kwaba umbulali.
Yilapho i-ductile iron (i-nodular iron) ingena khona. Amabanga afana no-65-45-12 noma 80-55-06 ahlinzeka ngenhlanganisela engcono yamandla nokumanzisa. Iziphatha njengensimbi kodwa igcina enye yalolo mlingisi omuhle wensimbi. Sashintsha lelo giya lokugaya iphepha saliyisa ensimbini ene-ferritic-pearlitic matrix, futhi inkinga yashabalala. Ukhiye bekuwukulungisa irediyasi ye-fillet kuphrofayela yamazinyo phakathi nesigaba sokuklama ukuze ivumelane kangcono nezinto ezibonakalayo. Lona akuwona umsebenzi wezinkawu ze-CAD; kudinga ukwazi ukuthi impahla igeleza kanjani ekubunjweni nalapho ukuncipha kungase kudale izindawo ezibuthakathaka.
Bese kuba nomdlalo we-alloying element. Ukwengeza kancane i-chromium noma i-molybdenum kungakhuphula ukumelana nokugqokwa nokuba lukhuni, kodwa futhi kuthinta ukusebenza kahle.

Ngamagiya ayinkimbinkimbi ngendlela emangalisayo noma amancane anemba, ukutshala imali kungaba inketho, kodwa ngensimbi ekhonjiwe, akuvamile kakhulu ngenxa yezinga lokushisa elincibilikayo kanye nokumanzi. Ijwayeleke kakhulu kumagiya awo akhethekile. Iphuzu liwukuthi, ukukhetha phakathi kwesihlabathi, igobolondo, ngisho nokusakazwa kwe-centrifugal kuthonya ukwakheka kokusanhlamvu, ukuzwakala, futhi ekugcineni, ukusebenza kwegiya ngaphansi komthwalo. Kufanele uqondanise indlela nosayizi wegiya, ubuningi, kanye nesigaba sekhwalithi.
Imishini: Lapho Ithiyori Ihlangana Neqiniso
Yilapho amaphupho ejometri ephelele afinyelela khona iqiniso lethuluzi lokuxoxa. I-cast iron iyaphuka. Ukukhanda izinyo legiya, ikakhulukazi ukubhoboza noma ukubumba, kudinga ukusethwa okuqinile kanye nejeometri yethuluzi elithile ukugwema ukuphuka emaphethelweni. Ukupholisa (noma ukuntuleka kwakho) kuyimpikiswano enkulu. Abanye bafunga ngomshini owomile onama-carbides amboziwe ukuze bagweme ukushaqeka okushisayo kanye nengxubevange yothuli lwensimbi oluxutshwa nesipholile. Abanye basebenzisa isipholile esinengcindezi ephezulu ukukhipha ama-chips nokulawula ukushisa.
Ngincika komile noma i-MQL (umthamo omncane wokuthambisa) kwabaningi izingxenye zegiya lensimbi ngemva kokuhlangenwe nakho okubi nge-seage epholile. Sasinenqwaba yamagiya ensimbi e-ductile yebhokisi lezolimo. Ngemva komshini, okokupholisa insalela kuhlanganiswe emigodini yebhawudo namagalari kawoyela. Kubangele ukugqwala kwendawo ngesikhathi sokuthutha, okwaholela esikhalazweni esibi. Manje, sicacisa amaphrothokholi okuhlanza kanye nokomisa ngokuphelele ngemuva komshini. Kuzwakala kuyisisekelo, kodwa yile mininingwane yenqubo ehlukanisa ingxenye enhle kwethembekile.
Ukuphothula imisebenzi efana nokugaya noma ukucija ngezinye izikhathi kuyadingeka ukuze kwenziwe izinhlelo zokusebenza ezinesivinini esikhulu. Kodwa kufanele uqaphele. Ukushisa okwedlulele kokugaya kungashintsha i-microstructure engaphezulu, kudale izindawo eziqinile, eziphukayo ezingase zichitheke. Ngokuvamile kungcono ukuphokophela ukuqedwa komshini wekhwalithi ephezulu kusuka ku-hobber noma i-shaper kunokuhlela ukuyigaya yonke. Futhi, ibuyela ekuklameni yonke inqubo ihlehle kusukela engxenyeni yokugcina edingekayo.
