Insimbi ekwazi ukumelana nokushisa ephansi, iqine kunensimbi engu-12CrMo, ukuqina kancane kancane, ku-500-550 ° C noma ngaphansi inokumelana nokushisa okuphezulu nokumelana ne-oxidation, kanye nezakhiwo ezinhle zomshini, ukusebenziseka kalula nokubanda kwepulasitiki okuhle. weldability fair. Isetshenziselwa ikakhulukazi ukukhiqizwa kwamapayipi ensimbi angenamthungo ahlukahlukene kanye neshidi.



15CrMo Izicelo:



Ipayipi lesitimu eliyinhloko lamapharamitha omusi angu-510 ° C, 530 ° C amapharamitha wesitimu amashubhu we-boiler superheater, ama-catheter kanye nekhanda le-steam elicindezela kakhulu, ngemuva kokucisha nokushisa, ekamelweni lokushisa lingasetshenziswa ukwenza izingxenye ezihlukahlukene ezibalulekile zomsebenzi.

Izakhiwo zemishiniIzinto Zensimbi ezilingana ne-SCM415
Ukwelashwa kokushisa kuyisilinganiso esisebenza kahle kakhulu sokuthuthukisa nokuguqula izakhiwo zensimbi eyindilinga eyi-alloy engu-15CrMo. Idlala indima ebaluleke kakhulu ekuthembekeni komkhiqizo kanye nomnotho. Ukwelashwa kokushisa kwensimbi eyindilinga eyi-15CrMo ingxubevange ngokuvamile kuhlanganisa ukwelashwa okuvamile kokushisa (i-annealing, normalizing, quenching, tempering) kanye nokwelashwa kokushisa okungaphezulu (ukucisha ubuso nokwelashwa kokushisa ngamakhemikhali—i-carburizing, i-nitriding, i-metalizing, njll.).

Ebunjiniyela bemishini, izingxenye eziningi zemishini, njengama-crankshafts, amagiya, ama-camshaft ezinjini ezivuthayo zangaphakathi, namagiya kuzinciphisi ezibalulekile, azidingi nje kuphela ukuqina obanele, ipulasitiki namandla okugoba emnyombo, kodwa futhi zidinga ukushuba okuphezulu kwendawo ngaphakathi kogqinsi oluthile. . Ukuqina, ukumelana nokugqoka okuphezulu namandla aphezulu okukhathala. Izindlela ezibalulwe ngenhla ezihlukahlukene zokwelapha ukushisa zinzima ukuhlangabezana nezidingo zokusebenza ezingenhla ngesikhathi esifanayo, futhi ukusetshenziswa kokwelashwa kokushisa okungaphezulu kuyindlela ephumelela kakhulu yokufeza lezi zidingo zokusebenza ngesikhathi esifanayo.

Ukwelashwa kokushisa okungaphezulu kuyindlela yokwelapha ukushisa eshintsha izici ezingaphezulu zensimbi eyingxube yengxubevange engu-15CrMo ngokushintsha ukwakheka kongqimba olungaphezulu.
I-surface quenching iwukwelapha ukushisa okushintsha isakhiwo esingaphezulu ngakunye ngaphandle kokushintsha ukwakheka kwamakhemikhali okungaphezulu. Ingabonakala ngefrikhwensi ephezulu, imvamisa emaphakathi noma indlela yokushisa yamanje yokungenisa imvamisa yamandla noma indlela yokushisa ilangabi. Isici esivamile ukuthi ubuso bensimbi eyindilinga eyi-15CrMo i-alloy round bushiselwa ngokushesha kumazinga okushisa okucisha, futhi lapho ukushisa kungadluliswa emgodleni wengxenye, kuphole ngokushesha, ukuze ukuqina kwendawo kuphezulu, kodwa umgogodla usenokuqina okuphezulu.

Ukwelashwa ngamakhemikhali kuyindlela yokwelapha ukushisa eshintsha ukwakheka kwamakhemikhali nokwakheka kongqimba olungaphezulu lwensimbi eyindilinga eyi-15CrMo. Ukwelashwa kokushisa ngamakhemikhali kungahlukaniswa kube izindlela ezifana ne-carburizing, nitriding, carbonitriding, kanye ne-metalizing ngokuya ngezakhi ezihlukene ezingenwe ebusweni bensimbi eyindilinga eyi-15CrMo. Isebenza kahle kakhulu ekuthuthukiseni nasekuthuthukiseni ukumelana nokugqokwa, ukumelana nokugqwala nokumelana nokukhathala kwensimbi eyindilinga eyi-15CrMo. Njengamanje, ukwelashwa kokushisa kwamakhemikhali kuye kwathuthuka ngokushesha, futhi kunezicelo eziningi zobuchwepheshe obusha.
