Precision Cold Drawn Tube
Main ntchito: Magalimoto, njinga zamoto, firiji zida, mbali hayidiroliki, mayendedwe, masilinda pneumatic, ndi makasitomala ena amene ali ndi zofunika mkulu zitsulo chitoliro kulondola, kusalala, ukhondo, ndi katundu makina.
1, Mbali yayikulu ya chitoliro chachitsulo chosasunthika ndikuti ilibe msoko wowotcherera ndipo imatha kupirira kupanikizika kwambiri.Chogulitsacho chikhoza kukhala chowawa kwambiri ngati choponyedwa kapena zigawo zozizira.
2, Chitoliro chozizira bwino chomwe chimakokedwa makamaka ndi dzenje lamkati, ndipo kukula kwa khoma lakunja kumakhala kulolerana kolimba komanso kolimba, ndipo kulondola kwake ndikokwera kwambiri.
Kuzizira kozizira (kapena kutsika kwamphamvu kwamphamvu) kwa chitoliro chozizira chachitsulo chowala bwino kumawonetsedwa ndi kutentha kwamphamvu-brittleness kusintha Tc.Chitsulo choyera kwambiri (0.01% C) chili ndi Tc ya 100C, ndipo chimakhala chokhazikika pansi pa kutentha uku.Ambiri a alloying zinthu ozizira adagulung'undisa mwatsatanetsatane kuwala chitsulo chitoliro kukweza toughness-Chimaona kusintha kutentha kwa ozizira adagulung'undisa mwatsatanetsatane kuwala zitsulo chitoliro ndi kuonjezera chizolowezi ozizira Chimaona.Pamene ductile fracture ili pamwamba pa kutentha kwa chipinda, kupasuka kwa chitoliro chozizira chozizira chowala kwambiri ndi fracture ya dimple, ndipo pamene fracture ya brittle pa kutentha kochepa, ndi fracture ya cleavage.
Zifukwa otsika kutentha embrittlement ozizira adagulung'undisa mwatsatanetsatane kuwala zitsulo chitoliro ndi:
(1) Pamene dislocations kwaiye gwero dislocation pa mapindikidwe otsekedwa ndi zopinga (monga malire a tirigu, wachiwiri wofanana), kupsyinjika m'deralo kuposa mphamvu ongoyerekeza ozizira adagulung'undisa mwatsatanetsatane wowala zitsulo chitoliro ndipo zimayambitsa microcracks.
(2) Zomangika zingapo zomangika zimapanga microcrack pamalire ambewu.
(3) Zomwe zimachitika pa mphambano ya ma slip band awiri {110) zimayambitsa kusuntha kosasunthika %26lt;010%26gt;, yomwe ndi microcrack yoboola pakati, yomwe imatha kung'ambika motsatira {100} ndege yodutsa (onani Chithunzi 1b).
Zomwe zimawonjezera kuzizira kozizira kwa mapaipi achitsulo owala bwino ndi awa:
(1) Chinthu cholimbitsa yankho cholimba.Phosphorus imawonjezera kutentha kwamphamvu kwambiri;palinso molybdenum, titaniyamu ndi vanadium;pamene zomwe zili zochepa, zimakhala ndi zotsatira zochepa, koma pamene zomwe zili pamwambazi, zinthu zomwe zimawonjezera kutentha kwa kusintha kwamphamvu ndi silicon, chromium ndi mkuwa;chepetsani kulimba-chibwibwi Kutentha kwa kutembenuka ndi faifi tambala, ndipo kulimba-chimayima kutembenuka kutentha ndi manganese.
(2) Zinthu zomwe zimapanga gawo lachiwiri.Chofunikira kwambiri pakuzizira kozizira kwa mipope yachitsulo yowoneka bwino ndi gawo lachiwiri ndi mpweya.Ndi kuwonjezeka kwa carbon zili ozizira adagulung'undisa mwatsatanetsatane mipope zitsulo owala, zili pearlite ozizira adagulung'undisa mwatsatanetsatane kuwala zitsulo mipope ukuwonjezeka, ndi kuwonjezeka pafupifupi 1% ya buku la pearlite.Kutentha kwa kusintha kwamphamvu-brittle kunakwera ndi 2.2 ° C pafupifupi.Chithunzi 2 chikuwonetsa zomwe zili mu kaboni muzitsulo za ferrite-pearlite pa brittleness.Kuphatikizika kwa ma microalloying monga titaniyamu, niobium ndi vanadium kumapanga ma nitrides obalalika kapena ma carbonitrides, zomwe zimapangitsa kuti kutentha kwapaipi kozizira kozizira kwambiri kukwera.
(3) Kukula kwambewu kumakhudza kutentha kwakusintha kwamphamvu.Mbewu zikafukira, kutentha kwamphamvu kumawonjezeka.Kuyeretsa njere kumachepetsa chizoloŵezi chozizira chozizira cha mipope yachitsulo yowala kwambiri, yomwe ndi njira yogwiritsidwa ntchito kwambiri.
