42crmo umbhobho wentsimbi ongenamthungo

Inkcazelo emfutshane:

Iinkcukacha ngemveliso:

Ububanzi bangaphandle bombhobho wensimbi 20-426

Umbhobho wentsimbi ubukhulu bodonga lwe-20-426

Intshayelelo yemveliso:

Injongo ye-42crmo ipayipi yensimbi engenamthungo: intsimbi ekhethekileyo yebhulorho yi "42crmo", intsimbi ekhethekileyo ye-automobile girder yi "42CRmo", intsimbi ekhethekileyo yesitya soxinzelelo "42Crmo".Olu hlobo lwensimbi luxhomekeke ekuhlengahlengisweni kwekhabhoni (C) umxholo wokuphucula iimpawu ze-mechanical zensimbi, ngoko ke, ngokutsho kwekhabhoni ephezulu kunye nephantsi, olu hlobo lwensimbi lunokwahlulwa lube: intsimbi ephantsi ye-carbon - carbon umxholo ngokubanzi ungaphantsi kwe-0.25%, njenge-10, i-20 yentsimbi, njl.;I-carbon steel ephakathi - umxholo wekhabhoni uphakathi kwe-0.25 ~ 0.60%, njenge-35, i-45 yensimbi, njl njl.Intsimbi enjalo ayiqhelekanga ukwenza imibhobho yentsimbi.

Iinkcukacha zenkqubo:

Inkcazo yokusebenza eshushu

Ubushushu bokufudumala 1150 ~ 1200 ° C, ukuqala kweqondo lokushisa 1130 ~ 1180 ° C, ubushushu bokuphela > 850 ° C, φ> 50mm, ukupholisa okucothayo.

Ukucaciswa kwesiqhelo

Ubushushu obuqhelekileyo 850 ~ 900 ° C, ngaphandle kwe-oven umoya obandayo.

Inkcazo yobushushu obuphezulu bobushushu

Ubushushu bobushushu bungama-680 ~ 700°C, ngaphandle kwe-oven ebandayo yomoya.

Inkcazo yokucima kunye nokufudumala

Ukushisa kwe-preheating 680 ~ 700 ° C, ukucima ukushisa kwe-840 ~ 880 ° C, ukupholisa ioli, ukushisa kwe-580 ° C, ukupholisa kwamanzi okanye ukupholisa ioli, ubunzima ≤217HBW.

Ukucaciswa kokuqina kunye nokuqina phantsi - ukucima ubushushu

Ukucima iqondo lobushushu 900°C, iqondo lobushushu 560°C, ukuqina (37±1) HRC

Inkcazo yokwenza lukhuni kunye nokuthoba

Ukucima iqondo lokushisa 900 ° C, iqondo lokushisa 150 ~ 180 ° C, ubunzima 54 ~ 60HRC.
