1. Dab tsi yog qhov sib npaug ntawm 45 # carbon steel seamless yeeb nkab? Nws txhais li cas?
Teb: Cov pa roj carbon sib npaug (CE) ntawm 45 # carbon steel yog li 0.45% -0.55%. Cov pa roj carbon sib npaug yog qhov taw qhia los ntsuas qhov weldability ntawm steel. Qhov siab dua qhov sib npaug ntawm cov pa roj carbon monoxide, qhov zoo dua qhov weldability, uas yog vim li cas 45 # yeeb nkab tsis yooj yim rau vuam.
2. Dab tsi yog qhov tsis xws luag ntawm carbon steel seamless kav?
Teb: Cov teeb meem tshwm sim muaj xws li: cov kab nrib pleb ntawm qhov chaw, nti, qhov pits, kev sib txuas sab hauv, huab cua npuas, tsis sib xws ntawm phab ntsa thickness, thiab khoov. Cov teeb meem no yuav cuam tshuam rau lub siab -cov kabmob muaj peev xwm thiab kev pabcuam lub neej ntawm cov yeeb nkab, yog li lawv yuav tsum tau muab tshem tawm thaum kuaj xyuas.
3. Puas yog 20 # carbon steel seamless yeeb nkab siv los ua cov khoom siv tshuab?
Teb: Nws tuaj yeem siv los ua kom qis -load mechanical shafts. 20# carbon steel muaj plasticity zoo thiab machinability, tab sis nws lub zog tsis siab. Rau siab -load shafts, 45 # lossis 16Mn seamless yeeb nkab tom qab quenching thiab tempering yog tsim nyog.
4. Dab tsi yog qhov sib txawv ntawm cov khoom ntawm carbon steel seamless yeeb nkab thiab stainless hlau yeeb nkab?
Teb: Cov pa roj carbon steel seamless yeeb nkab yog tsim los ntawm cov pa roj carbon thiab hlau, nrog cov tsis zoo corrosion; stainless hlau yeeb nkab muaj chromium, npib tsib xee thiab lwm yam alloying ntsiab, uas muaj corrosion kuj zoo heev, tab sis tus nqi siab dua. Cov pa roj carbon steel kav yog siv rau kev thauj mus los hauv kev lag luam, thaum cov kav hlau stainless siv rau lub sijhawm corrosive.
5. Yuav ua li cas xaiv cov qib ntawm carbon steel seamless yeeb nkab raws li kev ua haujlwm?
Teb: ① Tsis tshua muaj siab, tsis tshua muaj load, kev thauj mus los dav dav: xaiv 10 # lossis 20 # cov pa roj carbon zoo tib yam; ② Nruab nrab thiab siab siab, nruab nrab load, yuav tsum tau muaj zog thiab toughness: xaiv 16Mn siab - specification carbon steel; ③ Kev thauj khoom siab, siab zog, tsis muaj vuam yuav tsum tau: xaiv 45 # nruab nrab carbon steel (tom qab kev kho cua sov); ④ Tsawg kub lossis cuam tshuam- lub sijhawm tiv taus: muab qhov tseem ceeb rau 16Mn.
