I-4145H iyinsimbi ehlelekile esetshenziselwa ikakhulukazi ukukhiqiza kanye nokusetshenziswa kwamathuluzi okumba imithombo kawoyela. Insimbi icutshungulwa esithandweni se-arc futhi icutshungulwe ngobuchwepheshe bokucwenga okuthambile. Ngaphezu kwalokho, imishini yokubhoboza uwoyela ivame ukusetshenziselwa ukwenza ngcono ukusebenza kwezingcezu zokubhola. Uma usebenzisa insimbi engu-4145H emithonjeni eqondisayo, kungenzeka ukubhoboza nge-torque ephansi kanye nesivinini esikhulu, ngaleyo ndlela kuncishiswe ukuguga nokulimala kwezinsika zokumba.
Ngenxa yezakhiwo zensimbi ezincane ze-4145H zensimbi kanye nendawo encane yokuxhumana enembobo yokumba, kunzima ukwenza ikhadi lomehluko wengcindezi. Lesi sici senza insimbi engu-4145H ithembeke kakhulu ekusebenzeni kokumba, kuyilapho kunciphisa ukungqubuzana nomthombo kanye nokulahlekelwa okungadingekile.
Ukwakheka kwamakhemikhali kwensimbi ye-4145H nakho kuyisihluthulelo ekusebenzeni kwayo okuhle kakhulu. Isilinganiso esinengqondo sokubunjwa kwamakhemikhali singaqinisekisa ukusebenza okuzinzile kwensimbi ezindaweni eziyinkimbinkimbi ezifana nokushisa okuphezulu nokucindezela okukhulu. Ngokuvamile, ukwakheka kwamakhemikhali kwensimbi engu-4145H kuhlanganisa izakhi ezifana ne-carbon (C), i-silicon (Si), i-manganese (Mn), i-phosphorus (P), isulfure (S), i-chromium (Cr), ne-nickel (Ni). Okuqukethwe nesilinganiso salezi zakhi kungalungiswa ngokuya ngezidingo ezithile ukuze kuhlangatshezwane nezidingo zezimo zohlelo lokusebenza ezahlukene.
Njengensimbi enamandla amakhulu engxubevange, isetshenziswa kabanzi ekukhiqizeni ama-forgings futhi inezinzuzo ezilandelayo:
Amandla aphezulu: I-4145H inamandla okukhiqiza aphezulu namandla aqinile, okuvumela ama-forging ukuthi amelane nemithwalo emikhulu nezingcindezi. Lokhu kukwenza kube ukukhetha okuhle kwezinhlelo zokusebenza ezidinga izinto zokwakha zamandla aphezulu. Ukumelana nokugqokwa okuhle: Ngenxa yokwengezwa kwezakhi ze-alloying, i-4145H inokumelana okuhle nokugqokwa futhi ingamelana nemiphumela yokuguga, izinhlayiya ezilumayo, nokungqubuzana. Lokhu kwenza izinto ezisetshenziswayo zifaneleke kakhulu kuma-forgings asetshenziswa ezindaweni zokungqubuzana okuphezulu nokugqoka. Ukuqina okuhle: I-4145H inomthelela omuhle kakhulu wokuqina futhi ingagcina ukwakheka okuzinzile nokusebenza ngaphansi komthelela noma ukudlidliza. Lokhu kwenza ama-forgings asebenze ngaphansi kwezimo ezinzima futhi anokuphepha okuphezulu. Kulula ukuyicubungula: Nakuba i-4145H iyinsimbi enamandla amakhulu, isenezinto ezinhle zokucubungula. Ingakhiwa futhi icutshungulwe ngezinqubo ezinjengokubumba, ukwelashwa kokushisa, nokucubungula ngomshini ukuze kuhlangatshezwane nezidingo zomumo nosayizi abahlukene. Ukumelana nokugqwala: 4145H inokumelana nokugqwala okuhle kakhulu, ikakhulukazi ezindaweni ezishisa kakhulu nezinomswakama. Lokhu kwenza ama-forgings akwazi ukugcina ukuzinza endaweni yamakhemikhali anonya futhi andise impilo yawo yesevisi.
Kafushane, ukusetshenziswa kwensimbi engu-4145H kumathuluzi okumba umthombo kawoyela kubaluleke kakhulu. Ukucutshungulwa kwayo kwesithando somlilo se-arc kanye nobuchwepheshe bokucwenga okuthambile kunikeza izici ezinhle zokusebenza nokuqina. Isilinganiso esinengqondo sokwakheka kwamakhemikhali ayo siqinisekisa ukusebenza okuzinzile ngaphansi kwezimo zokusebenza ezinzima. Ngokuqhubeka kocwaningo kanye nokusungula izinto ezintsha, singalindela insimbi engu-4145H ukuthi ibambe iqhaza elikhulu emkhakheni wokumba umthombo kawoyela wesikhathi esizayo, ithuthukise ukusebenza kahle kokumba nokunciphisa izindleko.
