Kugulitsa kwa chitsimikizo cha 30CrMo aloyi zitsulo zopanga chitoliro
16Mn ndi chitsulo chochepa cha alloy champhamvu kwambiri: mpweya wa carbon ndi 0.1% - 0.25%, ndipo zinthu zazikulu za alloy manganese, silicon, vanadium, niobium ndi titaniyamu zimawonjezeredwa; Zonse za alloy zake ndizochepera 3%. Malinga ndi mphamvu, imagawidwa m'magulu anayi: 300, 350, 400 ndi 450MPa. Pali makamaka q295, Q345, Q390, Q420 ndi Q460 "Q" ndi chiyambi cha liwu lachi China la Pinyin la liwu loti "Qu" lomwe limapereka, ndipo nambala yotsatila ndiye malo ocheperako amtundu (σ s) Zizindikiro zotsatira ndi ogawanika, B, C ndi D malinga ndi zomwe zili zonyansa (sulfure ndi phosphorous) muzitsulo kuchokera pamwamba mpaka pansi ndi kusintha kwa carbon ndi manganese. Pakati pawo, zitsulo za Gulu A ndi B nthawi zambiri zimatchedwa 16Mn.
Malinga ndi mphamvu, imagawidwa m'magulu anayi: 300, 350, 400 ndi 450MPa.
Pali makamaka q295, Q345, Q390, Q420 ndi Q460.
16Mn chitoliro chachitsulo chosasunthika
16Mn chitoliro chachitsulo chosasunthika
16Mn chitoliro chachitsulo chosasunthika ndi mtundu wazinthu. Chitoliro chachitsulo chosasokonezeka kale chinkatchedwa chitoliro chachitsulo chosasokonezeka.
Njira yamakono ndi: Q345B chitoliro chopanda chitsulo. Zida zofanana ndi Q345C, Q345D ndi Q345E. Chizindikiro cha giredi A, B, C, de chikuwonetsa zofunikira zosiyanasiyana pakuyesa zotsatira. Kutentha koyeserera ndi +20 ° 0 ° mpaka 20 ° 40 ° motsatana. 16Mn ndi chitoliro chachitsulo chosasunthika.
ABCD ikuwonetsa kalasi yabwino Q235. Magiredi abwino agawika m’magiredi anayi A, B, C ndi D. kuchokera ku A mpaka D akusonyeza khalidwe kuchokera kumunsi mpaka kumtunda.
Zofunikira pamagawo osiyanasiyana amtundu ndi izi:
A - kupereka s, P, C, Mn, Si mankhwala zikuchokera ndi Fu, FY δ 5 (δ 10), 1800 ozizira kupinda mayeso akhoza kuperekedwa malinga ndi zosowa za wogula, koma palibe mphamvu mphamvu kulamulira, ndi zili carbon. ndipo manganese samatengedwa ngati njira yobweretsera.
B - perekani s, P, C, Mn, Si mankhwala opangidwa ndi Fu, FY δ 5 (δ 10), kuyesa kozizira 180 '. Amaperekanso mphamvu zogwirira ntchito AK ≥ 27j pa + 200C - kuwonjezera pa zofunikira za kalasi B, imaperekanso mphamvu zogwirira ntchito AK ≥ 27j pa 00C.
C - kuwonjezera pa zofunikira za mlingo B, mphamvu yowonongeka AK ≥ 27j pa - 200C imaperekedwanso. E -- kuphatikiza pa zofunikira za mulingo B, mphamvu yamphamvu AK ≥ 27j pa - 400C imaperekedwanso.
