Q345B lalikulu-m'mimba mwake wopanda msokonezo lalikulu chitsulo chitoliro ndi yaitali zitsulo mankhwala ndi gawo dzenje ndipo palibe seams, amene amapangidwa ndi zitsulo chitoliro chosakanizika ngati maziko a chuma anagubuduza kapena ozizira kujambula. Poyerekeza ndi zida zachitsulo zolimba monga zitsulo zozungulira, mapaipi achitsulo osasunthika okhala ndi mainchesi akulu amakhala opepuka pakulemera kwake pomwe kupindika ndi mphamvu zopindika ndizofanana. Ndiwo zitsulo zotsika mtengo ndipo zimagwiritsidwa ntchito kwambiri popanga zida zamakina ndi zida zamakina.

Q345B lalikulu m'mimba mwake opanda msokonezo mipope lalikulu zitsulo akhoza kugawidwa mu mipope lalikulu zitsulo ndi mipope wapadera woboola pakati zitsulo malingana ndi mawonekedwe osiyana mtanda gawo. Pamene gawo lozungulira lozungulira likukhudzidwa ndi kupanikizika kwa ma radial mkati kapena kunja, mphamvuyo imakhala yofanana. Choncho, mipope yambiri yachitsulo ndi mipope yozungulira. Komabe, mapaipi ozungulira amakhalanso ndi malire. Mwachitsanzo, pansi pa mkhalidwe wa kupindika kwa ndege, chitoliro chozungulira sichikhala champhamvu ngati mapaipi achitsulo opanda msoko ndi mapaipi amakona anayi mu mphamvu yopindika. Mapaipi a square ndi amakona anayi amagwiritsidwa ntchito kwambiri m'mafelemu ena aulimi, zitsulo ndi mipando yamatabwa, etc. Mipope yachitsulo yooneka ngati yapadera yokhala ndi mawonekedwe ena apakati amafunikiranso malinga ndi ntchito zosiyanasiyana.

Kodi ubwino wa Q345B lalikulu m'mimba mwake lalikulu zitsulo chitoliro ndi chiyani?
1. Pamwamba pa Q345B chitoliro chachitsulo chachikulu chokhala ndi m'mimba mwake chimakhala cholimba kwambiri ndipo chimakhala ndi mankhwala odana ndi dzimbiri komanso anti-dzimbiri. Mlingo wa okosijeni sudzakhala wothamanga kwambiri ndipo dzimbiri loyera silipanga paipi yachitsulo.
2. Imakhala ndi anti-corrosion and wear-resistant properties, kupanga chitoliro chachitsulo chosasunthika kukhala ndi moyo wautali wautumiki.
3. Mipope yachitsulo yopanda msoko imatetezedwa. Pambuyo pakuwotcha, galvanizing yotentha yotentha imachitidwa pa malo aliwonse a chitoliro chachitsulo chosasunthika, ndipo malo ozungulira ndi a concave amatetezedwa.
4. Chifukwa chitoliro chachitsulo chosasunthika chimakhala chotentha-kuviika malata kunja, chimapulumutsa nthawi yojambula kapena kupukuta, kupanga zomangamanga kukhala zosavuta.
5. Mipope yachitsulo yovimbika yotentha sidzaundana kapena kusweka ngakhale mkati mwa masiku 39, kuwapanga kukhala abwino kwambiri kumadera akumpoto.

Pakuvomerezedwa kwa polojekiti ya Q345B lalikulu-diameter lalikulu lachitsulo chitoliro, ndikofunikira kulabadira kusasinthika kwa ngodya zinayi, ndipo kupatuka kwa mbali zinayi kuli mkati mwa muyezo wadziko lonse. Muyezo wapadziko lonse wosinthitsa mapaipi opanda msoko ndi amakona anayi nthawi zambiri ndi: GB/T3094-2008, ndipo ukadali mulingo uwu. Cholakwika chamulingo wa R angle chasinthidwa. Chitoliro chachitsulo chowala cha square ndi champhamvu kwambiri kuposa chitoliro chowongoka cha square zitsulo potengera kukakamiza. Mtengo wa chitoliro chowala chachitsulo chowala ndi osachepera kwambiri. Chitoliro chowala chachitsulo chokhala ndi zitoliro chimakhala ndi mapeto a chitoliro panthawi yokonza. Pankhani ya mchira wosalala, kusankha mchira ndi muyeso wowonjezera.

Chifukwa chiyani mapaipi achitsulo a Q345B okhala ndi mainchesi akulu ayenera kutumizidwa? Chifukwa chachikulu ndi kukonza khalidwe la Q345B lalikulu m'mimba mwake lalikulu zitsulo mapaipi, kuphatikizapo:
(1) Pankhani yachitsulo cha carbon high ndi high alloy steel, kuzimitsa kumatha kukhala ndi mphamvu kuti ipititse patsogolo kubowola.
(2) Ponena za chitsulo chochepa cha carbon, kuzimitsa kungalowe m'malo mwa chithandizo cha kutentha kukonzekera kuzimitsa kulowetsedwa kungathe kuchepetsa mapindikidwe a mapaipi opanda phokoso ndikuchepetsa ndalama zopangira.
(3) Ponena za zitsulo zokhala ndi mpweya wambiri, kuzimitsa kumatha kuchotsa maukonde ogawa simenti, zomwe zimapindulitsa ku spheroidizing annealing.
(4) Kwa mipope ikuluikulu ndi sing'anga-kakulidwe opanda msokonezo kapena castings zitsulo ndi kwambiri anasintha mtanda zigawo, kuzimitsidwa angagwiritsidwe ntchito m'malo kutentha mankhwala kuchepetsa chizolowezi mapindikidwe ndi ang'onoang'ono kapena kukonzekera kutentha mankhwala.
(5) Zigawo zotsutsana ndi kutentha zowonongeka za mapaipi opanda phokoso zimatha kuzimitsidwa kuti zithetse kuwonongeka kwa kutentha kwambiri kuti athe kutenthedwanso.
(6) Amagwiritsidwa ntchito mu aluminiyamu kufa castings kuonjezera zachibadwa ferrite zili ndi kupititsa patsogolo mphamvu ndi kuvala kukana castings.
