42CRMO Chitoliro Chopanda Zitsulo
Cholinga cha chitoliro chachitsulo cha 42crmo: Chitsulo chapadera cha milatho ndi "42crmo", kalasi yapadera yachitsulo yazitsulo zamagalimoto ndi "42CRmo", ndipo kalasi yapadera yachitsulo yazitsulo ndi "42Crmo".Chitsulo chamtunduwu chimadalira kusintha zomwe zili mu carbon (C) kuti ziwongolere makina azitsulo.Choncho, malinga ndi mlingo wa okhutira mpweya, chitsulo chamtunduwu akhoza kugawidwa mu: Low mpweya zitsulo - mpweya zili zambiri zosakwana 0,25%, monga 10, 20 zitsulo, etc.;Sing'anga mpweya zitsulo-carbon zili zambiri pakati pa 0,25 ndi 0.60%, monga 35, 45 zitsulo, etc.;mpweya wa carbon steel-carbon carbon nthawi zambiri umaposa 0.60%.Chitsulo chamtunduwu nthawi zambiri sichimagwiritsidwa ntchito popanga mapaipi achitsulo.
Palibe kupsa mtima kodziwikiratu, kupindika pang'ono pakuzimitsa, kuchepa kwa kutopa kwambiri komanso kukana kukhudzidwa kangapo pambuyo pozimitsa ndi kutenthetsa chithandizo, kulimba kwamphamvu kwa kutentha kwapang'onopang'ono, kulimba kwamphamvu kwambiri komanso mphamvu yokhazikika pa kutentha kwakukulu.Chitsulocho nthawi zambiri chimagwiritsa ntchito kuzimitsa pamwamba pambuyo pozimitsa ndi kutentha ngati ndondomeko ya kutentha.
42crmo ndi zinthu zachitsulo.Kale, dzina lachitsulo.Dzina ndi: Q345B, zipangizo zofanana ndi Q345a, Q345c, Q345e, khalidwe kalasi chizindikiro ABCDE zikutanthauza kuti zotsatira mayeso kutentha si chofunika +20 madigiri 0 madigiri -20 madigiri 40 madigiri ABCD akuimira khalidwe mlingo Q235 mfundo mlingo mlingo. Pali magawo anayi a A, B, C, D, kuchokera ku A mpaka D omwe khalidweli limachokera kumunsi mpaka pamwamba.
Zofunikira pamagawo osiyanasiyana amtundu ndi izi:
A——Patsani mankhwala a S, P, C, Mn, Si ndi fu, fy, δ5 (δ10), malinga ndi zosowa za wogula, 1800 ozizira bend mayeso angaperekedwe, koma palibe mphamvu mphamvu kulamulira, carbon zomwe zili ndi manganese sizimaganiziridwa kuti ndizoyenera kupereka.
B——Perekani S, P, C, Mn, Si chemical composition and fu, fy, δ5 (δ10), kuyesa kozizira kwa 180’.Imaperekanso mphamvu zoyendera pa +200C, Ak≥27J
C-Kuphatikiza pa zofunikira zomwezo monga Kalasi B, imaperekanso mphamvu zokhuza Ak≥27J pa 00C.
D---- Kuphatikiza pa zofunikira za mulingo B, imaperekanso mphamvu yamphamvu Ak≥27J pa -200C.E---- Kuphatikiza pa zofunika za mulingo B, imaperekanso mphamvu yamphamvu Ak≥27J pa -400C.
Kumene mapaipi achitsulo a 42crmo opanda msoko ndi mapaipi achitsulo wamba amagwira ntchito motsatana: Mapaipi achitsulo amagawidwa m'mapaipi ozizira komanso otentha.
