Insimbi Yokwakha Ihlukaniswa Kanjani Ngokwesakhiwo Samakhemikhali

Insimbi ingenye yezinto ezisebenziseka kakhulu futhi ezisetshenziswa kabanzi ekusetshenzisweni kokubumba. Amandla ayo okubumba ngaphansi kwamandla okucindezela, kuhlanganiswe namandla aphezulu nokuqina, kwenza kube yinto ebalulekile ekukhiqizeni izingxenye ezibalulekile embonini yezimoto, yezindiza, yamandla, kanye neyokwakha. Enye yezindlela ezibaluleke kakhulu zokuhlukanisa insimbi yokubumba ngokwezakhi zayo zamakhemikhali. Lokhu kuhlukaniswa kusiza onjiniyela, amaqembu okuthenga, kanye nabakhiqizi ukukhetha izinga lensimbi elifanele ukuze bahlangabezane nezidingo ezithile zokusebenza.

Kungani Ukwakheka Kwamakhemikhali Kubalulekile Ekwenzeni Insimbi

Ukwakheka kwamakhemikhali kwensimbi kunquma izakhiwo zayo zomshini, impendulo yokwelashwa kokushisa, ukumelana nokugqwala, kanye nokufaneleka kwezinqubo ezahlukene zokubumba. Ngisho nezinguquko ezincane ezintweni ezifana ne-carbon, i-chromium, i-nickel, noma i-molybdenum zingathinta kakhulu ubulukhuni, ukuguquguquka, kanye nokuqina. Ngokuhlukanisa insimbi ngokwezinto zayo zokuhlanganisa, abakhiqizi bangakhetha izinto ezisebenza kahle kakhulu futhi ezingabizi kakhulu kuhlelo ngalunye.

Isibonelo, ku-i-sakysteel, ukukhetha izinga lensimbi kuhambisana ngokucophelela nendlela yokufaka izinto—kungakhathaliseki ukuthi ukufaka izinto ezishisayo, ukufaka izinto ezifudumele, noma ukufaka izinto ezibandayo—ukuqinisekisa ukuthi umkhiqizo oqediwe uhlangabezana nemigomo eqondile.

Ukuhlukaniswa Okuyinhloko Kwensimbi Yokwakha Ngokwesakhiwo Samakhemikhali

Insimbi yokwakha ngokuvamile ihlukaniswa ngamaqembu amane amakhulu ngokusekelwe ekwakhekeni kwamakhemikhali:

1. Izinsimbi Zekhabhoni

2. Izinsimbi Zengxubevange

3. Izinsimbi Zamathuluzi

4. Izinsimbi Ezingagqwali

Iqembu ngalinye linezigaba ezithile ezincike kumaphesenti kanye nohlobo lwezinto ezihlanganisiwe ezikhona.

1. Izinsimbi Zekhabhoni

Izinsimbi zekhabhoni ziwuhlobo olulula kakhulu lwensimbi, ikakhulukazi eyakhiwe ngensimbi nekhabhoni enezakhi ezincane. Okuqukethwe kwekhabhoni kuthonya kakhulu ubulukhuni, amandla, kanye nokuguquguquka.

Izinhlobo Zensimbi Yekhabhoni:

• Insimbi Ephansi Yekhabhoni (0.05% - 0.25% C)- Ukuqina okuhle kakhulu kanye nokushibilika, okusetshenziselwa amabhawodi, imiphini, kanye nokufakwa okuncane.

• Insimbi Yekhabhoni Ephakathi (0.25% - 0.60% C)– Amandla nokuqina okulinganiselayo, kulungele amagiya, ama-crankshaft, kanye nezinduku zokuxhuma.

• Insimbi Ekhabhoni Ephakeme (0.60% - 1.0% C)– Iqinile kakhulu futhi iqinile kodwa ayiboli kakhulu, isetshenziselwa izipilingi, amathuluzi okusika, kanye nezingxenye ezingagugi.

Izici Eziyinhloko:

• Ishibhile futhi itholakala kabanzi.

• Ubuchwepheshe obuhle bokusebenza emazingeni aphansi e-carbon.

• Amandla aphezulu okuqina ngokuphathwa kahle kokushisa.

2. Izinsimbi Zengxubevange

Izinsimbi ze-alloy ziqukethe izinto ezifana ne-chromium, i-nickel, i-molybdenum, i-vanadium, noma i-manganese ngaphezu kwe-carbon. Lezi zinto zithuthukisa ubulukhuni, amandla, ukuqina, kanye nokumelana nokugqwala.

Izinhlobo Ezivamile Zensimbi Ehlanganisiwe Yokwakha:

• Izinsimbi Ezine-alloy Eziphansi (≤ 5% iyonke izakhi zokuhlanganisa)– Izibonelo zifaka phakathi u-4140 no-4340, osetshenziselwa izingxenye zezimoto, izingxenye zezindiza, kanye nemigodi enzima.

• Izinsimbi Ezine-alloy Eziphezulu (izinto ezihlanganisiwe ezingaphezulu kuka-5%)– Yakhelwe ukusebenza okukhethekile, njengokumelana nokushisa okuphezulu noma ukumelana nokuguguleka okukhulu.

Izinzuzo:

• Izakhiwo zemishini ezithuthukisiwe ngaphezu kwezinsimbi zekhabhoni.

• Ukusebenza okungcono ngaphansi kwemithwalo ephezulu kanye nezimo zokuthinteka.

• Ifanele ukusetshenziswa kwezimboni okudinga kakhulu.

3. Izinsimbi Zamathuluzi

Izinsimbi zamathuluzi zenzelwe ngqo ukwenza amathuluzi, ama-dies, kanye nezikhunta. Zibonakala ngokuqina okuphezulu, ukumelana nokuguguleka, kanye nekhono lokugcina amandla emazingeni okushisa aphezulu.

Izinhlobo Ezinkulu Zensimbi Yamathuluzi Yokwakha:

• Ukuqinisa Amanzi (uchungechunge lwe-W)– Ishibhile kodwa ayimelani nokushisa, isetshenziselwa amathuluzi alula.

• Ukuqinisa Umoya (Uchungechunge lwe-A)– Ukuqina okuhle kakhulu ngesikhathi sokwelashwa kokushisa.

• Izinsimbi Ezisheshayo (uchungechunge lwe-M ne-T)– Iyakwazi ukusika ngesivinini esikhulu ngaphandle kokulahlekelwa ubulukhuni.

• Izinsimbi Zamathuluzi Ezishisayo (uchungechunge lwe-H)– Imelana nemijikelezo yokushisa nokupholisa ephindaphindwayo ezinqubweni zokubumba nezokukhipha.

Izicelo:

• Ukwakha ama-dies kanye nezibhakela.

• Amathuluzi okusika kanye nezingcezu zokubhoboza.

• Izikhunta zomjovo kanye nama-extrusion dies.

4. Izinsimbi Ezingagqwali

Izinsimbi ezingagqwali ziqukethe okungenani i-10.5% ye-chromium, eyakha ungqimba lwe-oxide olungasebenzi oluvikela ekugqwaleni. Lezi zinsimbi zilungele ukwakha izingxenye ezivezwe emswakama, amakhemikhali kanye namazinga okushisa aphezulu.

Izinhlobo Eziyinhloko Zensimbi Engagqwali Yokwakha:

• Izinsimbi Ezingagqwali Zase-Austenitic (uchungechunge lwama-300)– Okungewona ugesi, ukumelana nokugqwala okuhle kakhulu, okusetshenziswa kakhulu ekucubungulweni kokudla nasezindaweni zasolwandle.

• Izinsimbi Ezingagqwali Ze-Martensitic (uchungechunge lwama-400)– Ukuqina okuphezulu nokumelana nokuguguleka, kufanelekile emimeseni, ama-turbine blades, kanye nemigodi.

• Izinsimbi Ezingagqwali Ze-Ferritic– Ayikwazi ukumelana nogesi futhi ayigqwali, isetshenziselwa ukukhishwa kwezimoto kanye nezinhlelo zokwakha.

• Izinsimbi Ezingagqwali Ezimbili- Inhlanganisela yezakhiwo ze-austenitic neze-ferritic, ezinikeza amandla aphezulu kanye nokumelana nokugqwala.

Ithonya Lezinto Zokuhlanganisa Izinsimbi Ensimbini Yokwakha

Izinto ezithile zokuhlanganisa ensimbini zinquma ukusebenza kwayo ekwakheni nasekusetshenzisweni kokugcina:

• Ikhabhoni (C)– Kwandisa amandla nokuqina, kunciphisa ukuguguleka.

• I-Chromium (Cr)– Kuthuthukisa ukumelana nokuguguleka kanye nokumelana nokugqwala.

• I-Nickel (Ni)– Kuthuthukisa ukuqina kanye nokumelana nokugqwala.

• I-Molybdenum (Mo)– Kuqinisa amandla okushisa aphezulu kanye nokumelana nokukhukhuleka.

• I-Manganese (Mn)– Kuthuthukisa amandla nokuqina.

• I-Vanadium (V)– Kucwenga isakhiwo sezinhlamvu futhi kuthuthukisa ukumelana nokuguguleka.

• I-Silicon (Si)– Kuthuthukisa amandla kanye nokumelana nokushiswa kwe-oxidation.

Ukukhetha Insimbi Efanele Yokufaka Izicelo

Lapho bekhetha izinga lensimbi lokwakha, onjiniyela kumele bacabangele:

1. Izidingo Zemishini– Amandla, ubulukhuni, ukuqina, kanye nokumelana nokukhathala.

2. Ukumelana Nokugqwala– Kubalulekile ekusetshenzisweni kwasolwandle, kwamakhemikhali, noma kwangaphandle.

3. Amandla Okwelapha Ukushisa– Amandla okufeza izici ezifiselekayo ngokucisha, ukupholisa, noma ukuqinisa.

4. Izindleko Nokutholakala– Ukulinganisela ukusebenza kanye nemikhawulo yesabelomali.

5. Indawo Yokusebenza– Izinga lokushisa lokusebenza, ukuchayeka kumakhemikhali, kanye nezimo zomthwalo.

Ngokwesibonelo,i-sakysteelIsebenzisana eduze namakhasimende ukuze ifanise ukwakheka kwensimbi nenqubo yokwakheka, iqinisekise ukuthi umkhiqizo wokugcina uletha ukusebenza okuhle kakhulu kanye nobude besikhathi.

Izibonelo Eziwusizo Zokuhlukaniswa Kwensimbi Ekubumbeni

• Ama-crankshaft ezimoto– Ngokuvamile kwenziwa ngezinsimbi ze-alloy ze-carbon eziphakathi nendawo ezifana ne-4340 ukuze ziqine kakhulu.

• Imishayo ye-turbine yezindiza– Kudingeka izinsimbi ezine-alloy ephezulu ezinokumelana okuhle kakhulu nokushisa.

• Amathuluzi okuhlinza– Kwenziwe ngezinsimbi ezingagqwali ze-austenitic ukuze zivumelane nezinto eziphilayo futhi zimelane nokugqwala.

• Ama-dies okwakha- Kwenziwe ngensimbi yamathuluzi ashisayo e-H13 yokumelana nokushisa nokuqina.

Isiphetho

Ukuhlukanisa insimbi yokwakheka ngokwezakhi zamakhemikhali kubalulekile ukuqinisekisa ukuthi ingxenye eyenziwe yahlangabezana nezimfuneko ezidingekayo zokumelana nokushisa, ukushisa kanye nokugqwala. Izinsimbi zekhabhoni, izinsimbi ze-alloy, izinsimbi zamathuluzi, kanye nezinsimbi ezingagqwali ngayinye inendima ehlukile ekukhiqizeni, futhi ukukhetha kuncike ekusetshenzisweni okuhlosiwe, inqubo yokukhiqiza, kanye nezidingo zokusebenza.

Ngokuqonda lezi zigaba kanye nendima yento ngayinye yokuhlanganisa, abakhiqizi bangenza izinqumo ezinolwazi eziholela ezingxenyeni eziqinisiwe nezinokwethenjelwa. Ngobuchwepheshe kokubili ekukhetheni izinto kanye namasu okwakha athuthukile,i-sakysteelisalokhu ingumhlinzeki othembekile wemikhiqizo eyenziwe ngekhwalithi ephezulu kuzo zonke izimboni emhlabeni jikelele.
