Ipayipi lensimbi elingama-42crmo

Incazelo emfushane:

Ukucaciswa kokukhiqiza:

Ububanzi bangaphandle bepayipi lensimbi 20-426

Ipayipi lensimbi odongeni ukujiya 20-426

Isingeniso somkhiqizo:

Inhloso yepayipi lensimbi elingenamthungo elingu-42crmo: insimbi ekhethekile yebhuloho yi-“42crmo”, insimbi ekhethekile yegida yemoto yi-“42CRmo”, insimbi ekhethekile yomkhumbi wengcindezi yi-“42Crmo”.Lolu hlobo lwensimbi luncike ekulungisweni kwekhabhoni (C) okuqukethwe ukuze kuthuthukiswe izakhiwo zensimbi, ngakho-ke, ngokusho kokuqukethwe kwekhabhoni ephezulu naphansi, lolu hlobo lwensimbi lungahlukaniswa lube: insimbi ephansi ye-carbon - carbon okuqukethwe ngokuvamile kungaphansi kuka-0.25%, njengensimbi engu-10, 20, njll.;I-Medium carbon steel - okuqukethwe kwekhabhoni kuvamise ukuba phakathi kuka-0.25 ~ 0.60%, okufana nensimbi engu-35, 45, njll. I-carbon steel ephezulu - okuqukethwe kwekhabhoni ngokuvamile kungaphezulu kuka-0.60%.Insimbi enjalo ngokuvamile ayisetshenziselwa ukwenza amapayipi ensimbi.

Ukucaciswa kwenqubo:

Ukucaciswa kokusebenza okushisayo

Ukushisa kokushisa 1150 ~ 1200 ° C, izinga lokushisa eliqalayo 1130 ~ 1180 ° C, izinga lokushisa lokugcina > 850 ° C, φ> 50mm, ukupholisa kancane.

Ukucaciswa okujwayelekile

Izinga lokushisa elijwayelekile lingu-850 ~ 900°C, liphuma kuhhavini elibandayo.

Ukucaciswa kokushisa okuphezulu kwezinga lokushisa

Izinga lokushisa elingu-680 ~ 700°C, liphuma kuhhavini elibandayo.

Isici sokucisha nokushisa

Ukushisa okushisa ngaphambi kuka-680 ~ 700 ° C, ukushisa okucisha i-840 ~ 880 ° C, ukupholisa kwamafutha, ukushisa okushisayo kwe-580 ° C, ukupholisa kwamanzi noma ukupholisa uwoyela, ubulukhuni ≤217HBW.

Ukucaciswa kokuqina nokuqina ngaphansi - ukucisha izinga lokushisa

Izinga lokushisa elicishayo lingu-900°C, izinga lokushisa elingu-560°C, ubulukhuni (37±1) HRC

Ukucaciswa kokuqina kwe-induction kanye nokushisa

Amazinga okushisa okucisha angu-900°C, izinga lokushisa elingu-150~180°C, ubulukhuni 54 ~60HRC.
