Kutentha mankhwala mawonekedwe a mkulu chromium cast iron roll

Pali njira ziwiri zochizira kutentha kwa mipukutu yachitsulo cha chromium:

① Subcritical kutentha mankhwala pansi pa kutentha kwambiri kusintha;

② Chithandizo cha kutentha kwapamwamba pamwamba pa mfundo zitatu zofunika.

Nthawi zambiri mtundu wachiwiri umagwiritsidwa ntchito, ndipo njira zenizeni zimaphatikizira normalizing ndi kutentha. Pakali pano, m’malo mwa chitsulo chokwera kwambiri cha carbon high-liwiro ndi chitsulo cha chromium chopangidwa ndi chitsulo chopangira mipukutu chakhala chitukuko chachikulu cha mipukutu.

Chida chowumitsa makina opitilira muyeso chimakhala ndi mphamvu yolimba (kulemera kwa workpiece kumatha kufika matani makumi ambiri, kutalika kwa workpiece ndi mita sikisi), kuzimitsa mosalekeza, kuzimitsa kopitilira muyeso ndi ntchito zina. Ndizoyenera kwambiri kuzimitsa masikono olemetsa komanso mbali zazitali komanso zokhuthala. Makinawa ali ndi ntchito yamanja-yodziwikiratu ndipo ndi yoyenera kupanga magawo amodzi ndi batch. Kugwira ntchito kosavuta, ntchito zonse, kapangidwe koyenera, kukhazikitsa kosavuta komanso kukonza zolakwika.
