Chifukwa cha mtengo wapadziko lonse wazitsulo zachitsulo, posachedwapa mitengo yachitsulo inakwera kwambiri ndipo mtengo wachitsulo wa nkhumba unayamba kukwera. Komanso kuteteza zachilengedwe kumakhudzanso kuti wothandizila wapamwamba kwambiri wa carburizing watha. Kenako mtengo wachitsulo ukhoza kukwera mwezi wamtsogolo. Nazi mfundo zotsatirazi:
1 Chitsulo cha nkhumba ndi coke
Ku Shandong, Shanxi, Jiangsu, Hebei, Henan ndi madera ena ngakhale kuti zitsulo zotumizidwa ndi zazing'ono, koma pali opanga ochepa kwambiri pakupanga kotero kuti kusungirako sikokwanira. Kukwera kwa msika wazitsulo, mtengo wa coke ndi ore umakhudza kuti mitengo yachitsulo yakwera, sabata yatha chitsulo cha nkhumba chinakwera 1% - 3%, coke inanyamuka 2% ndipo zonsezo zachepetsedwa. Kuchuluka kwamphamvu kwachilimwe kumabwera, kufunikira ndi mtengo wa coke upitilira kukula. Koma chifukwa cha kutentha kwakukulu ndi nyengo yopuma imabwera, zitsulo ndi zoyambira 'zofuna zachitsulo za nkhumba sizili bwino, Zikuyembekezeka kuti mtengowo ukuwonjezeka osati mochuluka kwambiri panthawi yochepa.
2 Zowonongeka ndi carburizing wothandizira
The cupola of foundry anachotsedwa chifukwa cha zinthu zachilengedwe, mabungwe ambiri anayamba kusintha pafupipafupi magetsi ng'anjo kusungunuka, ntchito mtengo wotsika ndi zobwezerezedwanso zitsulo zitsulo ndi carburizing wothandizila kupanga ductile chitsulo kapena imvi chitsulo. graphite carburizing agent ndiye mfungulo, koma theka loyamba la chaka chitetezo cha chilengedwe chidapangitsa kuti mafakitole ambiri atsekedwe ndipo wosungira mafuta atha. Kuphatikiza apo, mitengo ya zinthu zakale idakwera kwambiri kotero kuti mtengo wamafakitale ukukwera komanso mitengo yopangira mapaipi achitsulo & zokometsera zitha kukweranso.
