Mbiri ya chitukuko cha chitoliro chaching'ono
Matumba osawoneka achitsulo ali ndi mbiri yazaka pafupifupi 100. Mtsogoleri wa ku Germany Mannesmann woyamba adapanga mphezi iwiri yofuula mu 1885, ndipo mphero yoyipitsitsa mu 1891. Mu 1903, The Switzer Rc Staieleel adapanga mphero chabe. Pambuyo pake, makina osiyanasiyana owonjezera monga mphero yopitilira pake yaipi yopitilira, yomwe idayamba kupanga malonda amakono achitsulo osasangalatsa. Mu 1930s, chifukwa chogwiritsa ntchito chitoliro atatu ogubudumpha, bongo ndi mibadwo yozizira, yolimbana ndi nyengo yowonjezereka, zosiyanasiyana komanso mtundu wa ziphuphu zazitsulo zidakonzedwa. Mu 1960s, chifukwa cha kusintha kwa mphero yopitilira muyeso komanso kutuluka kwa msambo wovuta kuchepetsa mphero, ndikupanga mpikisano pakati pa chitoliro chopanda chisamaliro chimalimbikitsidwa. Mu 1970s, chipika chopanda chisa chosawoneka bwino chinali chitoliro chowala chinali kuthamanga, ndipo dziko lachitsulo lachitsulo limadzaza pafupifupi 5% pachaka. Kuyambira 1953, China chafunikira kwambiri pakukula kwa malonda osawoneka achitsulo, ndipo poyamba adapanga dongosolo lopanga mitundu yonse ya mapaipi akuluakulu, apakati komanso yaying'ono. Nthawi zambiri, chitoliro cha mkuwa chimasunganso njira za billet mtanda ndikuboola.
Kugwiritsa ntchito ndi kugawidwa kwa chitoliro chachitsulo chosawoneka
Ntchito:
Chitoliro chachitsulo chosawoneka ndi mtundu wa gawo lazachuma, zomwe zimachita gawo lofunikira kwambiri muchuma cha dziko lonse. Amagwiritsidwa ntchito kwambiri ku mafuta, makampani opanga mankhwala, boiler, magetsi, zotumiza, mphamvu, quogy, mphamvu, madipatimenti ena.
Gulu:
① Malinga ndi gawo la mawonekedwe: chitoliro chozungulira cha gawo ndi chitoliro chapadera cha gawo.
② Malinga ndi zinthu: Chipika chachitsulo cha kaboni, chitoliro chachitsulo, chitoliro chachitsulo chopanda kapangidwe kake ndi chitoliro.
③ Malinga ndi njira yolumikizira: chitoliro cholumikizidwa ndi chitoliro cholumikizira.
④ Malinga ndi njira yopanga: Kuchulukitsa kotentha (Kutalika, kusokosera ndi kufulumira) chitoliro komanso chitoliro.
⑤ Malinga ndi cholinga: chitoliro cha obowola, chitoliro cha mafuta, chitoliro cha mapaipi, chitoliro ndi manyowa ndi feteleza wa feteleza.
Kupanga Technology ya chitoliro chachitsulo
Njira yayikulu yopanga (njira yayikulu yoyendera) yotentha yogundana ndi chitsulo chosanjikiza:
TUBE Black Kukonzekera ndi Kuyeserera kwa In. Tsitsani BUTRE BUWLSE → Kuchepetsa (Kuchepetsa (Kuchepetsa)
② Kupanga kwakukulu kwa ozizira (Chithunzi) chitoliro chachitsulo chosawoneka
Kukonzekera kopanda kanthu → Kusaka ndi mafuta ozizira → Kutentha kwazizira (kujambula) → Kutentha kwa → Kuchepetsa → Kumaliza → Kumaliza → Kumaliza.
Kupanga ndondomeko yoyenda yotentha yotentha yachitsulo ndi motere:
