1. Dab tsi yog cov yam ntxwv tseem ceeb ntawm 10 # seamless steel yeeb nkab?Teb: Lub ntsiab chemical muaj pes tsawg leeg ntawm 10 # seamless steel yeeb nkab yog tswj raws li nram no: C (0.07%-0.14%), Si (0.17%-0.37%), Mn (0.35%-0.65%), P≤0.035%, S≤0.035%. Nws yog cov hlau tsis muaj cov pa roj carbon tsawg nrog cov ntsiab lus qis, zoo plasticity thiab toughness, thiab yooj yim ua thiab tsim, uas yog tsim rau kev thauj mus los ntawm cov dej tsis tshua muaj siab thiab cov khoom siv dav dav.
2. Dab tsi yog qhov txawv ntawm 20 # seamless steel yeeb nkab thiab 10 # seamless steel yeeb nkab raws li cov khoom siv kho tshuab?Teb: Piv nrog 10 # seamless steel yeeb nkab, 20 # seamless steel yeeb nkab muaj cov pa roj carbon ntau dua, yog li nws cov khoom siv kho tshuab zoo dua me ntsis: lub zog tensile ntawm 20 # yog 410 -550MPa, lub zog tawm los yog ≥245MPa, thiab elongation yog ≥25%; Thaum lub zog tensile ntawm 10 # yog 335-475MPa, lub zog tawm los yog ≥195MPa, thiab qhov elongation yog ≥31%. 20# yog qhov tsim nyog rau kev thauj mus los nruab nrab ntawm cov kua nruab nrab thiab cov khoom siv tshuab nrog lub zog siab dua.
3. 35 # seamless steel yeeb nkab puas tuaj yeem siv los ua cov khoom siv tshuab?Teb: Yog. 35# seamless steel yeeb nkab yog nruab nrab carbon steel nrog lub zog nruab nrab (lub zog tensile 530-680MPa, yield zog ≥315MPa) thiab zoo toughness. Tom qab quenching thiab tempering kev kho cua sov, nws cov cuab yeej siv tau zoo tuaj yeem txhim kho ntxiv, uas yog siv dav hauv kev tsim cov tshuab shafts, txuas cov pas nrig thiab lwm yam khoom siv thauj khoom uas xav tau qee lub zog thiab toughness.
4. Qhov siab tshaj plaws ua haujlwm kub ntawm 45 # seamless steel yeeb nkab yog dab tsi?Teb: Qhov siab tshaj plaws ntev -lub sij hawm ua hauj lwm kub ntawm 45 # seamless steel yeeb nkab tsis ntau tshaj 450℃. Thaum qhov kub siab tshaj 450 degree, nws lub zog yuav txo qis, thiab oxidation thiab decarburization yuav yooj yim tshwm sim, uas yuav cuam tshuam rau lub neej kev pab cuam. Nws tsis haum rau siab - qhov chaw ua haujlwm kub xws li boiler raj.
5. Tus qauv twg yog 20# seamless steel yeeb nkab rau kev thauj mus los ntawm cov kua dej ua raws, thiab nws cov ntawv thov yog dab tsi?Teb: 20 # seamless steel yeeb nkab rau kev thauj mus los ntawm cov kua dej feem ntau ua raws li GB / T 8163 tus qauv. Nws yog dav siv hauv kev thauj mus los ntawm dej, roj, roj thiab lwm yam dej nruab nrab hauv roj av, tshuaj, hauv nroog thiab lwm yam lag luam. Nws tseem tuaj yeem siv los ua cov khoom siv dav dav hauv kev tsim khoom, xws li hydraulic kheej kheej thiab lub tes tsho bearing.
