Kuzimitsa ndi kutentha, komwe ndi njira yochizira kutentha yomwe nthawi zambiri imachitika pamapeto omaliza a zidutswa, imatsimikizira katundu wamakina apamwamba.
JINDALAI amaperekaCold Worked, Hot Rolled and Forged Steels for Quenching and Tempering yopereka mayankho osinthira makonda malinga ndi zomwe akufuna komanso zofunikira zina kuti akwaniritse zosowa za kasitomala aliyense malinga ndi magiredi ndi mbiri. Kampani yathu, ndi 10nthambi-maofesimuChinandi mphamvu yogawa pachaka yokwana 200,000 Tons, ndiye bwenzi labwino kwambiri lokulitsa bizinesi yanu.
Kodi Quench & Tempered Steel ndi chiyani?
Zitsulo zonse zimakhala ndi carbon, zomwe zimapangitsa kuti zikhale zovuta. Mpweya wochuluka wa carbon ukhoza kufooketsa kukhulupirika kwa chitsulo. Njira zozimitsa ndi kupsa mtima zimagwiritsidwa ntchito kuonjezera makina a carbon steel popanda kuwonjezera carbon.
Chitsulo chokhala ndi mpweya wambiri chimakhala ndi 0,60 mpaka 1.00% ya carbon content poyerekeza ndi 0.05 mpaka 0.25% ya chitsulo chochepa. Pamene chitsulo cha carbon high-carbon chikudutsa njira yozimitsira ndi kupsya mtima, mphamvu zake zamakina zimapangitsa kuti zikhale zolimba komanso zolimba.
Njirayi imawonetseranso zitsulo zazitsulo kuti ziziziziritsa mofulumira (kuzimitsa) ndikutenthanso ndi njira yoziziritsira pang'onopang'ono (kutentha). Njira zonse zozimitsa ndi kutenthetsa zili ndi udindo wowonjezera mphamvu ndi kulimba kwachitsulo.
Njira masitepe For Qkusokoneza ndiTempering
Pofuna kulimbikitsa kuuma ndi mphamvu yachitsulo, chithandizo chapadera cha kutentha, chotchedwa quenching ndi kutentha, chapangidwa. Kutentha ndi kutentha kungathe kugawidwa m'magulu atatu:
Austenitizing → kutentha pamwamba pa mzere wa GSK kudera la austenite
Quenching → kuziziritsa mwachangu m'munsimu γγ-αα-kusintha
Tempering → kutenthetsanso mpaka kutentha pang'ono ndikuzizira pang'onopang'ono
