Kutentha mankhwala achitsulo

Kutentha kwachitsulo nthawi zambiri kumaphatikizapo kuzimitsa, kutenthetsa ndi kutsekemera.Kutentha kwachitsulo kumakhudza katundu wazitsulo.

1, kuzimitsa: Kuzimitsa ndi kutentha zitsulo 800-900 madigiri, kusunga kwa nthawi inayake, ndiyeno mofulumira kuziziritsa mu madzi kapena mafuta, amene akhoza kusintha kuuma ndi.kuvala kukana kwachitsulo, koma onjezerani kuphulika kwachitsulo.

Mlingo woziziritsa umatsimikizira zotsatira zozimitsa.Kuzizira kofulumira, kumapangitsanso kuuma kwachitsulo ndi kuvala kukana kwachitsulo, koma kumapangitsa kuti brittleness ikhale yaikulu.Kuzimitsa kwachitsulo kumawonjezeka ndi kuwonjezeka kwa carbon content.Chitsulo chokhala ndi kabonipansi pa 0.2% sangathe kuzimitsidwa ndikuwumitsidwa.

Chitolirocho chikawotchedwa ndi flange, kutentha pafupi ndi weld kumakhala kofanana ndi kuzimitsa, zomwe zingayambitse kuumitsa.Komabe, chitsulo chochepa cha carbon chokhala ndi mpweya wocheperapo 0,2% sichidzaumitsidwa ndi kuzimitsa, chomwe ndi chimodzi mwa zifukwa zomwe chitsulo chochepa cha carbon chimakhala ndi weldability wabwino.

2. Kutentha: Chitsulo chozimitsidwa ndi cholimba komanso chosasunthika, ndipo chimapangitsanso kupsinjika kwamkati.Pofuna kuchepetsa brittleness yovutayi ndikuchotsa kupsinjika kwamkati, chitsulo chozimitsidwa nthawi zambiri chimatenthedwa mpaka pansi pa 550 ° C, ndiyeno chimakhazikika pambuyo posungira kutentha kuti chiwongolere kulimba ndi pulasitiki yachitsulo ndikukwaniritsa zofunikira zogwiritsira ntchito.

3. Annealing: Pofuna kuchepetsa kuuma ndi kukonza plasticity zitsulo, atsogolere processing, kapena kuthetsa brittleness zovuta ndi kupsyinjika mkati kwaiye kuzirala ndi kuwotcherera, chitsulo akhoza kutenthedwa mpaka madigiri 800-900, ndipo pang'onopang'ono utakhazikika pambuyo kuteteza kutentha kwa. kukwaniritsa zofunikira zogwiritsidwa ntchito.Mwachitsanzo, chitsulo choyera chotsekedwa pa madigiri 900-1100 chingachepetse kuuma ndi brittleness ndikupeza malleability.
