ABS Qib B Nkoj Hlau Phaj

Muab Cov Kev Xav Tau Tshwj Xeeb Zoo Piv txwv ntawm ABS Classification Society's Qib B Nkoj Hlau Phaj thiab Nws Daim Ntawv Thov Cov Ntaub Ntawv

Hauv kev ua haujlwm ntawm kev tsim nkoj, ABS (American Bureau of Shipping) Lub Koom Haum Saib Xyuas Kev Lag Luam tau tsim cov kev cai zoo thiab cov ncauj lus kom ntxaws ntawm Qib B Nkoj Hlau Phaj los lav kev nyab xeeb thiab kev ua haujlwm ntawm cov nkoj. Nov yog qee qhov xwm txheej tshwj xeeb ntawm cov kev xav tau zoo no nrog rau cov ntaub ntawv siv tau.

Ib qho tseem ceeb yog qhov kev xav tau ntawm cov cuab yeej cuab tam. Piv txwv li, lub zog tensile ntawm Qib B Nkoj Hlau Phaj raws li tau teev tseg los ntawm ABS yuav tsum nyob rau hauv thaj tsam ntawm 400 txog 500 MPa. Qhov no ua kom cov phaj hlau muaj lub zog txaus los tiv thaiv ntau yam quab yuam thiab kev ntxhov siab nws yuav ntsib thaum lub nkoj ua haujlwm. Lub zog tawm los, feem ntau teem ntawm 235 thiab 355 MPa, cim lub ntsiab lus ntawm cov yas deformation pib thiab yog qhov tseem ceeb rau kev txiav txim siab lub peev xwm ntawm lub phaj.

Lub elongation ntawm kev tawg, feem ntau yog li ntawm 20% mus rau 25%, qhia qhov ductility ntawm steel phaj. Cov cuab yeej no tso cai rau lub phaj kom deform mus rau ib qho twg yam tsis muaj kev tawg, muab kev nyab xeeb nyob rau hauv kev npaj txhij txog kev thauj khoom.

Hais txog cov tshuaj muaj pes tsawg leeg, cov ntsiab lus carbon yuav raug txwv rau {{0}}.22% ntawm qhov siab tshaj plaws kom sib npaug hardness thiab ductility. Manganese tuaj yeem raug teev kom nyob hauv 1.0% rau 1.6% txhawm rau txhim kho lub zog thiab tawv. Cov ntsiab lus phosphorus feem ntau yog txwv tsis pub ntau tshaj 0.045%, thiab cov ntsiab lus sulfur yog khaws cia ntawm 0.04% lossis qis dua los tiv thaiv brittleness thiab tawg.

Nyob rau hauv cov nqe lus ntawm daim ntawv thov, Qib B Ship Steel Phaj yog feem ntau siv nyob rau hauv kev tsim kho ntawm ntau yam nkoj Cheebtsam. Piv txwv li, nws tuaj yeem ua haujlwm nyob rau hauv kev tsim cov qauv hull, decks, bulkheads, thiab lwm yam khoom siv sab hauv. Lub phaj thickness tuaj yeem sib txawv nyob ntawm qhov chaw tshwj xeeb thiab ua haujlwm hauv lub nkoj. Nyob rau hauv lub hull, daim hlau nrog thicknesses li ntawm 10 mus rau 30 hli yuav siv tau, thaum lub decks, thicknesses ntawm 8 mus rau 20 hli yuav raug.
