Mfundo Zoti Mugwiritse Ntchito Pogwiritsa Ntchito Makina A Kutentha Kwamafupipafupi a Rail Rail Quenching
Tikamagwiritsa ntchito makina otenthetsera pafupipafupi kwambiri ndi chida chothandizira kuzimitsa njanji zowongolera, tiyenera kulabadira mfundo izi:
a. Kusankhidwa kwa makina othamanga Pazifukwa zina za magawo ena amachitidwe, pang’onopang’ono liwiro losunthira, ndizowonjezera zolimba, koma magwiridwe antchito amafupika. Ngati liwiro kusuntha ndi wosakwiya, kuuma pamwamba adzachepetsedwa, kotero liwiro kusuntha ayenera lizilamuliridwa mu uthunthu wa 1.2 ~ 3mm / s.
b. Kusankha kothetsa kutentha kwachinsinsi ndichinsinsi. Kutentha koyenera kwambiri kotsekera kuyenera kukhala pamwamba pa kutentha, komanso kusungunuka kwa phosphorous eutectic pansipa 957 ° C. Nthawi zambiri, kutentha kwa 900-950 ° C ndikoyenera.
c. Kuthetsa sing’anga: Chifukwa cha kuchuluka kwa graphite mu chitsulo chosungunuka, kuchuluka kwa kutentha kumachepa, ndipo nthawi yomweyo, mphamvu ya Si ndi Mn element 1 zinthu zimachepetsa kuzizirako kovuta. Chifukwa chake, kutentha kwapafupipafupi kotentha kotsekemera kwazitsulo zachitsulo sikutanthauza kutentha kwambiri kwa sing’anga yotseka. Nthawi zambiri, madzi apampopi amapopera madzi kuzirala, ndipo kuthamanga kwa madzi ndi 0.1 ~ 0.15MPa.
