LR DH36, LR EH36, Lr FH32 Shipbuilding Steel Phaj

 

 

LR EH 36:

 

Taw qhia: Kuj tseem muaj ntawv pov thawj los ntawm Lloyd's Register, nws yog lub zog siab-siab kub-kub shipbuilding phaj. Qhov "E" qhia tias cov phaj hlau muaj qhov zoo dua qhov kub thiab txias. Lub ntsiab lus ntawm "H" thiab "36" zoo ib yam li DH36.

Tshuaj muaj pes tsawg leeg (general range): Carbon (C) Tsawg dua lossis sib npaug rau {{0}}.18%, silicon (Si) Tsawg dua lossis sib npaug rau 0.50%, manganese (Mn) 0. sib npaug rau 0. rau 0.20%, npib tsib xee (Ni) Tsawg dua lossis sib npaug li 0.40%, molybdenum (Mo) Tsawg dua lossis sib npaug li 0.08%, niobium (Nb) 0.02 - 0.05%, vanadium (V) 0. los yog sib npaug li 0.015%.

Mechanical zog: Yield zog (ReH) Ntau dua los yog sib npaug rau 355 MPa, tensile zog (Rm) 490 - 630 MPa, elongation (A%) Ntau dua lossis sib npaug 21. Qhov cuam tshuam lub zog (AKV2) feem ntau yog {{4} }J ntawm -40 degree .

Kev xa khoom raws li txoj cai: Kub dov, TMCP (thermomechanical tswj kev ua haujlwm). Normalizing, tempering, quenching, thiab lwm yam kuj tuaj yeem ua raws li qhov xav tau.

Nto zoo: Cov txheej nyias nyias ntawm nplai, xeb, thiab tsis pom kev roughness, reticulation, khawb, thiab lwm yam hauv zos tsis xws luag tshwm sim los ntawm nias-hauv nplai thiab yob uas tsis cuam tshuam nrog kev soj ntsuam saum npoo raug tso cai. Txawm li cas los xij, qhov tob yuav tsum tsis txhob ntau dua qhov tsis zoo sib txawv ntawm cov hlau thickness thiab yuav tsum xyuas kom meej qhov tsawg kawg nkaus tso cai thickness ntawm cov hlau.

Quenching	Tsis siv rau ib txwm siv. Feem ntau, AH36 marine steel phaj tsis quenched.

 

LR FH32:

 

Taw qhia: Muaj ntawv pov thawj los ntawm Lloyd's Register, "F" qhia txog qhov kub thiab txias. Nws feem ntau yog siv rau hauv nkoj thiab marine engineering cov qauv nrog cov kev xav tau siab dua rau kev ua haujlwm ntawm qhov kub thiab txias. Muaj plaub qib zoo: A, D, E, thiab F. Qhov cuam tshuam ntawm qib F tuaj yeem ncav cuag -60 degree .

Tshuaj muaj pes tsawg leeg: Zoo ib yam li DH36 thiab EH36, tab sis cov ntsiab lus tshwj xeeb yuav txawv raws li nws qhov kev ua tau zoo ntawm qhov kub thiab txias.

Mechanical zog: Nws muaj lub zog muaj zog thiab zoo kub-kub toughness. Cov txiaj ntsig tshwj xeeb tuaj yeem raug xa mus rau cov qauv tsim nyog lossis cov ntaub ntawv muab los ntawm cov tuam ntxhab.

Kev xa khoom raws li txoj cai: Kub dov yog siv los ua thawj lub xeev kho cua sov. TMCP lossis N-xeev daim hlau nkoj tuaj yeem muab tau.

Z-kev taw qhia kev ua haujlwm: Cov qib Z-kev coj ua tau zoo yog Z15, Z25, thiab Z35. Rau FH32 steel phaj qib, Z-kev taw qhia kev ua tau zoo yog sawv cev los ntawm FH32Z15, FH32Z25, FH32Z35 lossis FH32-Z15, FH32-Z25, FH32-Z35.

Qhov yuav tsum tau ua kom zoo: Cov hlau phaj nto yuav tsum tsis txhob muaj teeb meem tsis xws luag xws li npuas, nti, tawg, folds, inclusions, thiab pressed-in scale. Cov hlau yuav tsum tsis muaj qhov pom kev delamination.
