Kuphathwe ngokushisaAmazinyo ebhakede le-caterpillarZinikeza ukuqina okungenakuqhathaniswa. Zinikeza ukusebenza okuphezulu kanye nokonga okukhulu kwezindleko zesikhathi eside. Lokhu kuzenza zibe yisinqumo esifanele semisebenzi enzima yokuthutha umhlaba.Izinyo lensimbi ye-CAT alloykuqinisekisa ukuthembeka ezimweni ezinzima. Abaqhubi bayazuza ekwakhiweni kwabo okuqinile.
Izinto Ezibalulekile Okufanele Uzicabangele
- Ukwelashwa ngokushisa kwenzaAmazinyo ebhakede le-caterpillar kuqine kakhulu. Lokhu kuzisiza ukuthi zihlale isikhathi eside futhi zimelane nokuphula imisebenzi enzima yokumba.
- La mazinyo akhethekile agubha kangcono futhi ngokushesha. Lokhu kusho ukuthiimishini yakho sebenza kahle kakhulu futhi wenze okwengeziwe.
- Ukusebenzisa amazinyo ahlinzwe ngokushisa konga imali ngokuhamba kwesikhathi. Adinga ukushintshwa okuncane kanye nokulungiswa okuncane, okunciphisa izindleko zizonke.
Ukuqina Okuthuthukisiwe Kwamazinyo Ebhakede Le-Caterpillar Eliphathwa Ngokushisa
Isayensi Ebangela Ukwelashwa Kokushisa Kokuphila Isikhathi Eside
Ukwelashwa ngokushisa kuguqula ngokuyisisekelo izakhiwo zensimbi, okwenza kube kuhle kakhulu ekusetshenzisweni okunzima njengokuthutha umhlaba. Amazinyo ebhakede le-caterpillar adlula enkambisweni ephelele yokwelashwa ngokushisa. Abakhiqizi basebenzisaizinto ezisezingeni eliphezulungezinhlobo zamakhemikhali ezizinzile. Le nqubo ithuthukisa kokubili ubulukhuni kanye nokuqina. Isakhiwo esincane sensimbi ephathwa ngokushisa sinegalelo ngqo ekwandiseni isikhathi eside. Izinqubo zokucima ezilungiselelwe zifeza i-martensite enhle. Lesi sakhiwo esincane sinikeza inhlanganisela enhle yamandla aphezulu, ukumelana nokuguguleka, kanye nokuqina. Sivumela amazinyo ebhakede ukuthi amelane nokuthinteka okukhulu, ukucindezela, kanye namandla okugoba. Lokhu kuholela empilweni yenkonzo ende uma kuqhathaniswa nezinto ezinezakhiwo ezincane eziqinile noma eziqinile. Isibonelo, insimbi engu-30CrMnSi ifinyelela ukuqina komthelela okuhle (74 J) ngokushisa kokucima okuhle okungu-870 °C, okunikeza i-martensite enhle. Ukuphambuka kuleli zinga lokushisa, kungaba ngaphansi noma ngaphezulu, kunciphisa ukuqina komthelela. Amazinga okushisa aphansi aholela ekuqineni okungalingani noma i-ferrite eyengeziwe. Amazinga okushisa aphezulu abangela ukugoba kwe-austenite kanye ne-martensite eqinile.
| Uhlobo Lwensimbi | Izinga Lokushisa Lokucima (°C) | Isakhiwo esincane | Izakhiwo |
|---|---|---|---|
| 30CrMnSi | 870 | I-martensite enhle kakhulu | Amandla aphezulu, ukuqina okuhle, ukuqina okuphezulu komthelela (74 J) |
| 30CrMnSi | Ngaphansi kuka-870 | I-austenitization engalingani noma i-ferrite eyengeziwe | Ukuqina komthelela okunciphile |
| 30CrMnSi | Ngaphezulu kuka-870 | I-martensite emangelengele (ngenxa yokwanda kokusanhlamvu kwe-austenite) | Ukuqina komthelela okunciphile |
Lesi sakhiwo sangaphakathi esicwengekile siyinto ehlukanisayo ebalulekile.
