Kubwezeretsanso maoda aukadaulo, chitoliro chachitsulo cha alloy chazinthuA333 GR6, mfundo zake ndi 168.3*7.11, ndipochitoliro chachitsulo cha kaboni GB/T9948, 20#, specification ndi 114.3*6.02, ndi zina zotero.

Zotsatirazi zikuwonetsa miyezo ndi zipangizo zomwe maoda a uinjiniya adzakumana nazo:

Chitoliro chachitsulo chosapanga dzimbiri cha 20# GB8163 choyendera madzimadzi

Kodi chitoliro chachitsulo chosasunthika chimatanthauza chiyani? Chitolirochi ndi mtundu womwe timanena nthawi zambiri, monga 20#, 45#, zomwe zimayimira kapangidwe kake ka mankhwala ndi mphamvu zake monga mphamvu yokoka, mphamvu yotulutsa, ndi kuchuluka kwa kukula. Izi ndi zida za chitoliro chachitsulo chosasunthika zomwe zimagwiritsidwa ntchito kwambiri, miyezo yopangira ndi ntchito zomwe zafotokozedwa mwachidule ndi wolemba.

1.GB/T8162-2018, Mapaipi achitsulo chosasunthika, omwe amagwiritsidwa ntchito kwambiri mu uinjiniya wa zomangamanga, kukonza makina, zomangamanga ndi zina. Zipangizo zoyimira: 20#, 45#, q345b, 40Cr, 42CrMo, ndi zina zotero;

2. GB/T8163-2018, chitoliro chachitsulo chopanda msoko chonyamulira madzi, chomwe chimagwiritsidwa ntchito makamaka pakupanga mapaipi okhala ndi mphamvu yochepa. Zipangizo zoyimira: 20#, q345b;
Chitoliro chachitsulo chosapanga dzimbiri cha 45# GB8162

3.GB/T3087-2017, mapaipi achitsulo opanda zingwe a boiler okhala ndi mphamvu zochepa komanso zapakati, omwe amagwiritsidwa ntchito kwambiri popanga mapangidwe osiyanasiyana a mapaipi a nthunzi otentha kwambiri, mapaipi amadzi otentha a boiler okhala ndi mphamvu zochepa komanso zapakati, ndi mapaipi a nthunzi otentha kwambiri ndi mapaipi a njerwa za arch za boilers za locomotive.
