Types ntawm carbon steel kav:
Carbon steel kav yuav muab faib uaseamless kavthiabwelded kav(steel seam steel kav,kauv kav, high zaus welded steel kav) raws li txoj kev tsim khoom. Seamless steel kav yog tsim los ntawm kub dov los yog txias txias, thiab muaj lub zog siab thiab nruj. Welded steel yeeb nkab yog tsim los ntawm dov steel phaj los yog steel sawb mus rau hauv ib tug cylindrical zoo, thiab ces txuas lub weld seams los ntawm kuj welding, submerged arc vuam thiab lwm txoj kev.
Cov pa roj carbon steel seamless kav tau muab faib ua ob hom: kub dov (extruded) seamless steel kav thiab txias-draw (dov) seamless steel kav vim lawv cov txheej txheem tsim khoom sib txawv. Cold drawn (dov) raj tau muab faib ua ob hom: cov raj puag ncig thiab cov raj tshwj xeeb.
1) Kub dov (extruded) seamless steel yeeb nkab: round tube billet → cua sov → tho → peb-yob cross dov, nruam dov los yog extrusion → stripping → sizing (los yog txo) → txias → straightening → hydraulic kuaj (los yog Flaw detection) → cim → cia
2) Cold drawn (dov) seamless steel yeeb nkab: round tube dawb paug → cua sov → tho → taub hau → annealing → pickling → oiling (tooj liab plating) → multi-pass txias drawing (txias dov) → blank raj → tshav kub kho → straightening → hydrostatic kuaj (kev kuaj pom qhov tsis haum) → cim → khaws cia
Classification ntawm carbon steel:
Mild steel (tseem hu ua lub teeb steel):
Cov ntsiab lus carbon feem ntau yog nyob nruab nrab ntawm {{0}}.04% thiab 0.30%. Cov pa roj carbon tsawg muaj qhov zoo ductility thiab toughness, tuaj yeem ua tiav kub thiab txias, thiab yooj yim rau vuam. Feem ntau siv cov hlau tsis tshua muaj xws li Q195, Q215, Q235, thiab lwm yam.
Nruab nrab carbon steel:
Cov ntsiab lus carbon feem ntau yog nyob nruab nrab ntawm {{0}}.30% thiab 0.60%. Cov pa roj carbon nruab nrab muaj lub zog siab thiab hardness, tab sis tsis tshua muaj ductility thiab toughness. Feem ntau siv nruab nrab carbon steels suav nrog 45 # steel, 40Cr thiab lwm yam.
High Carbon Steel:
Cov ntsiab lus carbon feem ntau yog nyob nruab nrab ntawm 0.60% thiab 2.00%. High carbon steel muaj lub zog siab thiab hardness, tab sis tsis tshua muaj ductility thiab toughness, thiab tsis zoo weldability. Feem ntau siv high carbon steels xws li 65Mn, T8, T10, thiab lwm yam.
Carbon steel kav yuav muab faib ua seamless steel kav thiab welded steel kav raws li txoj kev ntau lawm. Seamless steel kav yog tsim los ntawm kub dov los yog txias txias, thiab muaj lub zog siab thiab nruj. Welded steel yeeb nkab yog tsim los ntawm dov steel phaj los yog steel sawb mus rau hauv ib tug cylindrical zoo, thiab ces txuas lub weld seams los ntawm kuj welding, submerged arc vuam thiab lwm txoj kev.
