Zomangira mafakitale amapangidwa akalumikidzidwa zosiyanasiyana ndi miyezo.DIN934

Zomangira mafakitale amapangidwa mu akalumikidzidwa zosiyanasiyana ndi miyezo.Zitsulo kaloti ali ndi luso mkulu kwambiri kuyimitsa kupsyinjika mkulu kwambiri mchikakamizo cha kutentha mankhwala, kutsogolera kusankha aloyi izi popanga mabawuti zitsulo ntchito mu zomangamanga mafakitale.Ferroalloy zitsulo ndi amtengo mpweya wambiri wa carbon ndi katundu wapamwamba kwambiri kuposa chitsulo choyera, chomwe chimakhala chofewa kwambiri.Zoonadi, kuwonjezera pa carbon, mankhwala okhazikika monga manganese, silicon, sulfure, phosphorous, ndipo nthawi zina ngakhale vanadium (vanadium imawonjezeredwa kuzitsulo zachitsulo zomwe zimafuna elasticity) amapezeka muzitsulo zachitsulo.
M'makampani omangamanga, ma bolts ndi mtedza amagwiritsidwa ntchito kwambiri popanga mashedi, milatho, madamu ndi magetsi. kapena kuwotcherera arc pogwiritsa ntchito maelekitirodi, malingana ndi kufunikira kolumikizana ndi mbale yachitsulo ndi beam. Njira iliyonse yolumikizira ili ndi ubwino ndi kuipa kwake, zomwe tidzakambirana pansipa.
Zomangira zomwe zimagwiritsidwa ntchito popanga zolumikizira zomangira zimapangidwa ndi chitsulo chapamwamba kwambiri, chomwe nthawi zambiri chimakhala chitsulo cha giredi 10.9. Gulu 10.9 zikutanthauza kuti kulimba kwamphamvu kwa wononga zomangira ndi pafupifupi 1040 N/mm2, ndipo imatha kupirira mpaka 90% ya zonse. kupsinjika komwe kumagwiritsidwa ntchito ku wononga thupi m'dera zotanuka popanda kusinthika kosatha.Poyerekeza ndi chitsulo cha 4.8, chitsulo cha 5.6, chitsulo chowuma 8.8, zomangira zomangira zimakhala ndi mphamvu zolimba kwambiri komanso zimakhala ndi chithandizo cha kutentha chovuta kwambiri popanga.
Mosiyana ndi muyezo muyezo hexagon mabawuti ndi mtedza, muyezo hexagon mabawuti ndi mtedza amapangidwa molingana ndi DIN931 muyezo monga magiya theka, malinga DIN933 muyezo monga magiya zonse, ndi zomangira hexagonal ndi osavuta, nthawi zambiri amapangidwa malinga ndi muyezo DIN6914.Kuphatikiza mtedza pa Zomangira zomangira zimakhalanso ndi thupi komanso kutalika kuposa mtedza wamba wa hex wopangidwa ku DIN934, wowonetsa kukana kupsinjika kwambiri, wopangidwa ku DIN6915. Zomangira zapamangidwezi zimakhala ndi 10HV ndipo nthawi zambiri zimakhala zakuda zakuda za matt phosphating kuti zithandizire kukhazikika kwa dzimbiri kapena kuviika kotentha kokhala ndi malata kapena kuya. siliva chrome matt, onse okhala ndi zitsulo zomaliza.Amagwiritsidwa ntchito mu zinc ndipo ali ndi kukana kwabwino kwa chilengedwe.
