Wopanga machubu opanda zitsulo adzafotokozera mwachidule zamagulu ndi ntchito ya chubu cha carbon steel.

1. General mpweya zitsulo chubu

Nthawi zambiri, chitsulo chokhala ndi mpweya wa ≤0.25% chimatchedwa chitsulo chochepa cha carbon. Mapangidwe a annealed a low carbon steel ndi ferrite ndi pearlite pang'ono. Zili ndi mphamvu zochepa komanso zolimba, pulasitiki yabwino komanso yolimba, ndipo ndiyosavuta kujambula, sitampu, extrude, Forging ndi kuwotcherera, yomwe 20Cr zitsulo zimagwiritsidwa ntchito kwambiri. Chitsulocho chimakhala ndi mphamvu zinazake. Pambuyo pozimitsa ndi kutentha kutentha pang'ono, chitsulo ichi chimakhala ndi makina abwino omveka bwino, kulimba kwa kutentha kochepa, komanso kupsa mtima sikuwonekera.

Zogwiritsa:M'makampani opanga makina, ndi oyenera kupanga magawo opangidwa ndi welded ndi magawo omwe sakhala ndi nkhawa kwambiri pambuyo popanga, kupondaponda komanso kukonza makina. M'mafakitale opangira ma turbine ndi ma boiler, amagwiritsidwa ntchito kwambiri pamapaipi, ma flanges, ndi zina zambiri zomwe zimagwira ntchito muzofalitsa zosawononga. Mitu ndi zomangira zosiyanasiyana; Ndi oyeneranso kupanga magawo ang'onoang'ono ndi apakatikati a carburizing ndi carbonitriding m'magalimoto, mathirakitala ndi kupanga makina ambiri, monga nsapato za brake m'manja, ma lever shafts, ndi mafoloko othamanga a gearbox pamagalimoto, magiya ophatikizika ndi ma camshaft pa mathirakitala, kuyimitsidwa koyimitsidwa. mitsinje, tchire lamkati ndi lakunja la olinganiza, ndi zina zotero; popanga makina olemera ndi apakatikati, monga ndodo zomangirira kapena zoponderezedwa, maunyolo, ma levers, manja, zida, ndi zina.

2. Low carbon steel chubu
Chitsulo chochepa cha carbon: Chitsulo chochepa cha carbon chokhala ndi mpweya woposa 0.15% chimagwiritsidwa ntchito pazitsulo, tchire, sprockets, ndi nkhungu zina zapulasitiki zomwe zimafuna kuuma kwakukulu ndi kukana kuvala bwino pamtunda pambuyo pa carburizing ndi kuzimitsa ndi kutentha kwapansi. Chigawo. Pambuyo pa carburizing ndi kuzimitsa ndi kutentha pang'ono, chitsulo chochepa cha carbon chimakhala ndi mawonekedwe apamwamba a carbon martensite pamwamba ndi otsika-carbon martensite pakati, kuti atsimikizire kuti pamwamba pamakhala kuuma kwakukulu ndi kukana kuvala kwakukulu pamene pakati ali ndi kuuma kwambiri. Mphamvu zabwino ndi kulimba. Ndizoyenera kupanga nsapato za brake zamanja, ma lever shafts, mafoloko othamanga a gearbox, magiya ongodutsa, ma camshaft pa mathirakitala, ma shafts oyimitsidwa, tchire lamkati ndi lakunja la zowerengera, manja, zowongolera ndi zina.

3. Sing'anga mpweya zitsulo chubu
Chitsulo chapakati cha carbon: Chitsulo cha carbon chokhala ndi mpweya wa 0.25% mpaka 0.60%. 30, 35, 40, 45, 50, 55 ndi magiredi ena ndi a sing'anga-carbon zitsulo. Chifukwa chakuti pearlite yomwe ili muzitsulo imawonjezeka, mphamvu zake ndi kuuma kwake zimakhala zapamwamba kuposa kale. Kuuma kumatha kuwonjezeka kwambiri pambuyo pozimitsa. Pakati pawo, zitsulo 45 ndizofala kwambiri. Chitsulo cha 45 ndi chitsulo champhamvu chapakati chapakati cha carbon chozimitsidwa komanso chotenthedwa, chomwe chimakhala ndi pulasitiki komanso kulimba, komanso kudula bwino. Itha kupeza zabwino zonse zamakina pozimitsa ndi kutenthetsa chithandizo, koma kuuma kwake ndikosavuta. Amagwiritsidwa ntchito popanga magawo omwe ali ndi mphamvu zambiri komanso kulimba kwapakati. Nthawi zambiri amagwiritsidwa ntchito pozimitsidwa ndi kupsya mtima kapena kukhazikika. Kuti chitsulocho chikhale cholimba chofunikira ndikuchotsa kupsinjika kwake kotsalira, chitsulocho chiyenera kuzimitsidwa ndiyeno kutenthedwa kukhala sorbite.
