Q345B zitsulo kapangidwe chitoliro chitsimikizo wopanga
Mu mndandanda wopanda chitoliro wachitsulo, pali chinthu chotchedwa Q345B chopanda chitsulo chachitsulo, chomwe ndi cha mndandanda wa alloy otsika. Pakati pa zipangizo zochepa za alloy, nkhaniyi ndi yofala kwambiri. Q345B chitoliro chopanda chitsulo chomwe chimatchedwa 16Mn chitoliro chopanda chitsulo. Pali njira zambiri zamagulu. Malinga ndi kupanga, pali: otentha adagulung'undisa opanda msoko chitoliro ndi ozizira adagulung'undisa msoko chitoliro. Malinga ndi cholinga chake, pali: chitoliro chachitsulo chosasunthika pamapangidwe ambiri, chitoliro chachitsulo chosasunthika chotumizira madzimadzi, chitoliro chopanda chitsulo chosapanga dzimbiri chapakati komanso chocheperako komanso chitoliro chopanda chitsulo chopopera. Malinga ndi zinthu, pali: apamwamba mpweya structural zitsulo zitsulo chitoliro chosasunthika chitsulo chitoliro, otsika aloyi structural zitsulo zitsulo chitoliro ndi aloyi zitsulo zitsulo chitoliro. Chitoliro chachitsulo chosasunthika chimagwiritsidwa ntchito kwambiri, chimatha kusinthidwa kukhala magawo amakina, omwe amagwiritsidwa ntchito kunyamula madzi kapena gasi, amagwiritsidwa ntchito ngati mayendedwe oyendetsa, ndipo amagwiritsidwa ntchito pomanga nyumba zolimba.
Muyezo wakunja wa Q345B wopanda chitsulo chitoliro ndi gb709 ndipo mulingo wamkati wamkulu ndi GB / t1591-94.
Njira yotchulira dzina ndiyofanana ndi Q345B.
Chifukwa cha kukhazikitsidwa kwa muyezo, mbale iyi yachitsulo imaloledwa kuperekedwa ndi kulolerana koipa.
Q345 opanda zitsulo chitoliro ndi mtundu wa zinthu zitsulo chitoliro. Q imayimira zokolola za nkhaniyi. Zotsatira za 345 zimatanthawuza mtengo wamtengo wapatali wa zinthu izi, zomwe zili pafupi ndi 345. Mtengo wa zokolola umachepa ndi kuwonjezeka kwa makulidwe a zinthu.
Q345A, palibe zotsatira;
Q345B, 20 ° kutentha kwachibadwa;
Q345C, 0 digiri mphamvu;
Q345D, ndi - 20 digiri zotsatira;
Q345E ndi - 40 digiri mphamvu.
Paziwopsezo zosiyanasiyana, zomwe zimakhudzidwa zimasiyananso.
Q345A, Q345B, Q345C, Q345D, Q345E, Uku ndiko kusiyana kwa magiredi, omwe makamaka amayimira kuti kutentha kwamphamvu ndikosiyana.
Q345B opanda zitsulo chitoliro ndi mtundu wa zinthu zitsulo, amene akhoza kugawidwa mu Q345A, Q345B, Q345C, Q345D ndi Q345E malinga kalasi. Zomwe zimayimira ndikuti kutentha kwamphamvu kumakhala kosiyana. Q345A, palibe zotsatira; Q345B, 20 ° kutentha kwachilengedwe; Q345C, 0 digiri mphamvu; Q345D, ndi - 20 digiri zotsatira; Q345E ndi - 40 digiri mphamvu.
Odziwika ndi kupanga ndondomeko: otentha adagulung'undisa mosokonekera chitoliro ndi ozizira adagulung'undisa msoko chitoliro.
Malinga ndi kagulu ka ntchito, pali: chitoliro chachitsulo chosasunthika pamapangidwe onse, chitoliro chachitsulo chosasunthika chotumizira madzimadzi, chitoliro chachitsulo chosasunthika chapakatikati ndi chotsika kuthamanga kwa boiler ndi chitoliro chachitsulo chosasinthika cha boiler yothamanga kwambiri.
Ndi zakuthupi: apamwamba mpweya structural zitsulo popanda zitsulo chitoliro, otsika aloyi structural zitsulo zitsulo chitoliro, aloyi zitsulo zitsulo chitoliro.
1. Chitoliro chopanda msoko (GB / t8162-2018) ndi chitoliro chachitsulo chosasunthika pamapangidwe ambiri komanso makina.
2. Chitoliro chachitsulo chosasunthika choyendetsa madzimadzi (GB / t8163-2018) ndi chitoliro chachitsulo chosasunthika chomwe chimagwiritsidwa ntchito kunyamula madzi, mafuta, gasi ndi madzi ena.
3. Chitoliro chachitsulo chosasunthika cha boiler yotsika komanso yapakatikati (gb3087-2018) ndi chitoliro chapamwamba cha carbon structural chitsulo chotenthetsera chotenthetsera komanso chozizira chokoka (chogudubuza) chopanda chitsulo chomwe chimagwiritsidwa ntchito popanga chitoliro chotentha kwambiri, chitoliro chamadzi otentha cha boiler yotsika komanso yapakatikati. , chitoliro cha nthunzi chotentha kwambiri ndi chitoliro cha njerwa cha arch cha boiler ya locomotive.
4. Chitoliro chachitsulo chosasunthika cha boiler yothamanga kwambiri (gb5310-2018) ndi chitsulo chapamwamba kwambiri cha kaboni, chitsulo cha aloyi ndi chitoliro chosasunthika chosatentha chachitsulo chosapanga dzimbiri chomwe chimagwiritsidwa ntchito popanga chotenthetsera chamadzi otenthetsera boiler ndi kupanikizika kwambiri ndi kupitilira apo.
