A53 mkulu kuthamanga opanda msokonezo zitsulo chitoliro wopanga
A53 opanda zitsulo chitoliro ndi zinthu American muyezo zitsulo chitoliro, mmene a53-a ndi lofanana zoweta 10 # zitsulo, a53-b ndi lofanana zoweta 20 # zitsulo, ndi a53-f ndi lofanana zoweta Q235 zakuthupi. Njira zazikulu zopangira chitoliro chopanda chitsulo cha A53 ndizojambula zozizira komanso kugudubuza kotentha. Kusiyanitsa kwakukulu pakati pa awiriwa ndikuti kupanga chitoliro chozizira chosasunthika chosasunthika kumakhala kovuta kwambiri kuposa kugudubuza kotentha. Maonekedwe, chitoliro chachitsulo chosasunthika chozizira ndi chachifupi kuposa chitoliro chachitsulo chosasunthika chotentha. Kukhuthala kwa khoma la chitoliro chachitsulo chosasunthika chozizira nthawi zambiri chimakhala chocheperako kuposa chitoliro chachitsulo chosasunthika chotentha, koma mawonekedwe ake amawoneka owala. Pamwamba pa otentha adagulung'undisa zitsulo chitoliro ndi akhakula. Njira yayikulu yopangira ndi chubu chozungulira chopanda kanthu → kutentha → perforation → kugudubuza katatu pamtanda, kugudubuza mosalekeza kapena kutulutsa → kuvula chitoliro → kukula (kapena kuchepetsa) → kuziziritsa → kuwongola → kuyesa kwa hydrostatic (kapena kuzindikira zolakwika) → kuyika chizindikiro → malo osungira. Kuwerengera chilinganizo cha kulemera kwa mita imodzi ya A53 yopanda chitsulo chitoliro: 0.02466 * khoma makulidwe * (m'mimba mwake akunja - makulidwe a khoma).
Chitoliro chachitsulo chosasunthika chokwera kwambiri komanso chitoliro cha boiler chothamanga kwambiri ndi mtundu wa chitoliro cha boiler, chomwe chili mgulu la chitoliro chopanda chitsulo. Njira yopangira ndi yofanana ndi chitoliro chosasunthika, koma pali zofunikira zokhwima pazitsulo zachitsulo zomwe zimagwiritsidwa ntchito popanga chitoliro chachitsulo. Machubu a boiler othamanga nthawi zambiri amagwiritsidwa ntchito pansi pa kutentha kwambiri komanso kupanikizika kwambiri. Machubu opopera oponderezedwa kwambiri amagwiritsidwa ntchito makamaka popanga machubu otenthetsera, machubu otenthetsera, machubu a mpweya, machubu akulu a nthunzi, ndi zina zambiri zama boiler othamanga kwambiri komanso othamanga kwambiri.
Machubu otenthetsera otsika komanso apakatikati gb3087-2008 ndi machubu otenthetsera kwambiri GB5310-2008 ndizitsulo zapamwamba kwambiri za carbon structural zitsulo zotentha komanso zoziziritsa (zopindika) zopanda msoko zopangira machubu otentha kwambiri, machubu amadzi otentha otsika komanso othamanga kwambiri. ma boiler okhala ndi zida zosiyanasiyana ndi machubu otentha kwambiri, machubu akulu a utsi, machubu ang'onoang'ono a utsi ndi machubu a njerwa opangira ma locomotive boilers. Chitoliro chachitsulo chosasunthika (GB / t8162-2008) ndi chitoliro chachitsulo chosasunthika pamapangidwe ambiri komanso makina.
Mafotokozedwe ndi mawonekedwe: machubu achitsulo a GB5310-2008 osasunthika a ma boiler othamanga kwambiri, m'mimba mwake wakunja kwa machubu otentha ndi 22 ~ 530mm, ndipo makulidwe a khoma ndi 20 ~ 70mm. Chitoliro chozizira chokoka (chozizira) chimakhala ndi mainchesi akunja a 10 ~ 108mm ndi makulidwe a khoma la 2.0 ~ 13.0mm.
Chitoliro chapadera chopangidwa ndi chitsulo chosasinthika ndi dzina lambiri la chitoliro chopanda chitsulo chokhala ndi mawonekedwe ena kupatula chitoliro chozungulira. Malinga ndi mawonekedwe osiyanasiyana ndi kukula kwa chitsulo chitoliro gawo, akhoza kugawidwa mu ofanana khoma makulidwe apadera-woboola pakati zitsulo chitoliro (code D), osalingana khoma makulidwe wapadera woboola pakati zitsulo chitoliro (code BD) ndi variable awiri woboola pakati wapadera woboola pakati. Chitoliro chachitsulo chosasinthika (code BJ). Chitoliro chapadera chowoneka bwino chachitsulo chimagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana omangira, zida ndi zida zamakina. Poyerekeza ndi chitoliro chozungulira, chitoliro chowoneka mwapadera nthawi zambiri chimakhala ndi mphindi yokulirapo ya inertia ndi gawo modulus, ndipo chimakhala chopindika komanso kukana kugwedezeka, komwe kumatha kuchepetsa kwambiri kulemera kwake ndikusunga chitsulo:
(1) High khalidwe mpweya structural zitsulo makalasi monga 20g, 20mng ndi 25mng.
(2) Aloyi structural zitsulo makalasi: 15mog, 20mog, 12crmog, 15CrMoG, 12CR2MOG, 12crmovg, 12Cr3MoVSiTiB, etc.
(3) Kuphatikiza pa kutsimikizira kapangidwe ka mankhwala ndi makina, machubu a boiler a 1Cr18Ni9 ndi 1cr18ni11nb omwe amagwiritsidwa ntchito muzitsulo za dzimbiri zosagwira kutentha adzayesedwa ndi hydrostatic test, flaring and flattening test imodzi ndi imodzi. Mipope yachitsulo iyenera kuperekedwa pakatenthedwe.
Komanso, pali zofunika zina za microstructure, kukula kwa tirigu ndi decarburization wosanjikiza wa chitoliro yomalizidwa zitsulo.
