Ndi zinthu ziti zomwe zili bwino kwambiri popangira mapanelo a nsagwada?

Pali zinthu zingapo zomwe ziyenera kuganiziridwa posankha zinthu zopangira nsagwada, kuphatikizapo mphamvu ya nsagwada yomwe imayenera kupirira, kuuma ndi kuphulika kwa zinthuzo, komanso kukwera mtengo kwake. Malinga ndi zotsatira zakusaka, zotsatirazi ndizomwe zili zoyenera kwambiri popangira mbale za nsagwada:
Chitsulo Chapamwamba cha Manganese:
Chitsulo chokwera cha manganese ndi chinthu chachikhalidwe cha mbale ya nsagwada ya nsagwada, yomwe ili ndi zotsatira zabwino zokana katundu ndi mawonekedwe owumitsa. Pansi pa kukakamizidwa, chitsulo chapamwamba cha manganese chikhoza kulimbikitsidwa mosalekeza, kotero kuti nthawi zonse chimavala ndi kulimbikitsidwa pa ntchito mpaka atavala mpaka sichikhoza kugwiritsidwa ntchito.
Pamene mbale yapamwamba ya manganese yachitsulo ikakhudzidwa kapena kuvala, kusintha kwa martensitic komwe kunachititsa kuti austenite kukhale kosavuta, ndipo kukana kuvala kumakhala bwino.
Chitsulo Chapakatikati cha Manganese:
Chitsulo chapakati cha manganese ndikuchepetsa zomwe zili ndi manganese muzitsulo zazitsulo za manganese, ndikuwonjezera zinthu zina kuti zithandizire kukana kwake. Malinga ndi kutsimikizira koyeserera, moyo weniweni wautumiki wa mbale yachitsulo yachitsulo ya manganese ndi pafupifupi 20% kuposa chitsulo chokwera cha manganese, ndipo mtengo wake ndi wofanana ndi chitsulo chokwera cha manganese.
High Chrome Cast Iron:
Chovala chachitsulo chachitsulo cha chromium chokhala ndi nsagwada chimakhala cholimba kwambiri, koma chimakhala chosalimba. Chifukwa chake, opanga ena atengera njira yopangira nsagwada zophatikizika, kuphatikiza chitsulo cha chromium chachikulu ndi chitsulo cha manganese chambiri kuti asunge kukana kuvala komanso kukhala ndi kulimba kwabwino.
Chitsulo Chapakatikati cha Carbon Low Alloy:
Chitsulo chapakati cha carbon low alloy cast chitha kugwiritsidwa ntchito mosiyanasiyana chifukwa chakulimba kwake komanso kulimba kwake. Zinthuzi zimatha kuthana ndi mikhalidwe ya mbale ya nsagwada m'malo osiyanasiyana ogwira ntchito.

Chitsulo chosinthidwa chapamwamba cha manganese:
Pofuna kupititsa patsogolo moyo wautumiki wa mbale ya nsagwada, zida zosiyanasiyana za nsagwada zapangidwa, monga kuwonjezera Cr, Mo, W, Ti, V, Nb ndi zinthu zina kuti zisinthe chitsulo chachikulu cha manganese, ndi kulimbikitsa kubalalika. chithandizo cha chitsulo chachikulu cha manganese kuti chiwongolere kuuma kwake koyamba ndi kutulutsa mphamvu.
Zophatikizika:
Enambale za nsagwadantchito zipangizo gulu, monga mkulu chromium kuponyedwa chitsulo ndi mkulu manganese zitsulo gulu zakuthupi, mbale nsagwada amapereka masewera athunthu avale kukana mkulu chromium kuponyedwa chitsulo ndi kulimba mkulu wa chitsulo mkulu manganese, kuti moyo utumiki wa mbale nsagwada. wakhala bwino kwambiri.
Posankha nsagwada, m'pofunika kusankha mogwirizana ndi zochitika zenizeni za ntchito ndi makhalidwe akuthupi. Mwachitsanzo, chitsulo chachikulu cha manganese ndichoyenera kugwiritsidwa ntchito nthawi zambiri, pomwe chitsulo chapakati cha manganese ndi choyenera kuzinthu zolimba kwambiri, chitsulo chokwera cha chromium ndi choyenera kugwiritsidwa ntchito povala kwambiri, ndipo chitsulo chapakati cha carbon low alloy cast ndi choyenera kuvala sing'anga. mikhalidwe. Chilichonse chili ndi ubwino wake ndi zofooka zake, kotero kusankha zinthu zoyenera kumafuna kulingalira mozama za ntchito ndi mtengo wake.
