LR AH36 SHIPBUILDING STEEL Plate

Ua raws li cov qauv ntawm Lloyd's Register (LR) kev faib tawm hauv zej zog ua piv txwv, cov kev cai tshwj xeeb rau kev ua haujlwm ntawm LR AH36 shipbuilding steel phaj yuav suav nrog cov hauv qab no (cov kev xav tau tiag tiag yuav txawv nyob ntawm qhov tshwj xeeb ntawm cov kev faib tawm sib txawv thiab cov phiaj xwm tshwj xeeb. xav tau):

Tshuaj muaj pes tsawg leeg:

- Cov ntsiab lus ntawm cov pa roj carbon (C) feem ntau muaj qee yam kev txwv los xyuas kom meej lub zog thiab weldability ntawm cov hlau.
- Cov ntsiab lus ntawm manganese (Mn) yuav tsum muaj nyob rau hauv cov kev cai, uas yuav pab txhim kho lub zog thiab toughness ntawm cov hlau.
- Cov ntsiab lus ntawm cov ntsiab lus xws li silicon (Si), phosphorus (P), thiab sulfur (S) kuj yuav tsum tau tswj hwm ntawm cov qib tshwj xeeb kom ntseeg tau ntau yam khoom ntawm cov hlau. Piv txwv li, qhov kev xav tau dav dav rau cov ntsiab lus phosphorus tsawg dua lossis sib npaug rau 0.025%, thiab rau cov ntsiab lus sulfur tsawg dua lossis sib npaug li 0.015%.

Mechanical Properties:

- Lub zog yield (sab saum toj yield zog) Ntau dua lossis sib npaug li 355 MPa.
- Lub zog tensile nyob nruab nrab ntawm 490 - 630 MPa.
- Lub elongation tom qab tawg ntau dua lossis sib npaug li 21%.
- Hais txog kev cuam tshuam toughness, muaj cov kev cai tshwj xeeb rau kev cuam tshuam lub zog nqus ntawm qhov kub sib txawv. Piv txwv li, ntawm 0 degree , rau cov hlau daim hlau nrog lub thickness tsis pub tshaj 50 hli, lub longitudinal thiab transverse cuam tshuam lub zog nqus yuav tsum tsis pub tsawg tshaj 34J thiab 24J feem; thaum lub thickness yog 50 - 70mm, qhov ntev thiab transverse cuam tshuam lub zog nqus yuav tsum tsis pub tsawg tshaj 41J thiab 27J feem; Thaum lub thickness yog 70 - 150mm, qhov ntev thiab transverse cuam tshuam lub zog nqus yuav tsum tsis pub tsawg tshaj 50J thiab 34J feem.

Delivery State: Feem ntau yog xa hauv lub xeev normalized.

Dimensions, Shape, Weight and Allowable Deviations: Lawv yuav tsum tau ua raws li cov kev cai ntawm cov qauv muaj feem xyuam (xws li GAH36/T709), thiab qhov qis deviation ntawm thickness feem ntau yog -0.3 hli.

Steel Phaj Nto Zoo:

- Lub nto yuav tsum tsis txhob muaj teeb meem xws li npuas, nti, tawg, folds, inclusions, thiab nias-hauv nplai.
- Yuav tsum tsis muaj qhov pom kev pom ntawm qhov muag liab qab.

Lwm yam yuav tsum tau muaj:

- Raws li qhov yuav tsum tau muaj ntawm tus neeg yuav khoom thiab los ntawm kev pom zoo ntawm tus neeg muag khoom thiab tus neeg yuav khoom, kev sim tsis muaj kev puas tsuaj, xws li kev kuaj xyuas qhov tsis zoo, tuaj yeem ua tiav. Rau cov hlau phaj nrog Z-kev taw qhia kev ua tau zoo (xws li Z15, Z25, Z35), sib raug Z-kev taw qhia kev ntsuas kev ua tau zoo kuj yuav tsum tau.

Hauv kev tsim khoom tiag tiag, cov ntsiab lus hauv qab no kuj yuav tsum tau sau tseg:

1. nruj me ntsis tswj kev tswj cov ntaub ntawv raw kom ntseeg tau tias cov qib steel, cua sov tooj, tus naj npawb ntawm daim, specifications, thiab qhov hnyav ntawm lub nkoj phaj billet yog raws li daim ntawv pov thawj zoo, lub nto zoo ua raws li cov kev cai, thiab lawv yog stacked los ntawm steel qib, kub tooj, thiab specifications raws li xav tau.
2. Ua raws li cov txheej txheem ntawm kev xa cov hlau los ntawm cov cua sov, ua kom tiav cov txheej txheem kub ntawm tus lej nrhiav, thiab zam qhov tshwm sim ntawm cov txheej txheem kev sib tsoo vim muaj cov lej sib xyaw.
3. Thaum lub sij hawm ua cua sov, nws yog ib qho tsim nyog los tswj cov cua kub thiab qhov kub ntawm txhua ntu. Piv txwv li, qhov cua sov feem ntau yog 8 - 10 min / cm, thiab qhov kub siab tshaj plaws cua sov tsis tshaj 1300 degree.
4. Thaum lub sij hawm dov, yuav tsum tau them nyiaj mloog mus rau qhov pib dov kub, piv txwv li, feem ntau yog nyob nruab nrab ntawm 1000 - 1100 degree . Rau cov ntaub ntawv ntawm kev tswj-kub dov, nws yog ib qho tsim nyog los xyuas kom meej tias qhov pib kub ntawm kev ua tiav dov, qhov kawg dov kub, thiab cov txheej txheem txias tom qab dov ua raws li qhov yuav tsum tau ua. Piv txwv li, rau cov hlau phaj nrog cov lus qhia ntawm 9 - 14mm, cov pa rolling tuaj yeem siv tau, nrog rau qhov pib kub ntawm qhov kawg dov ntawm 900 degree , thiab cua txias lossis dej txias rau 670 - 750 degree ; rau steel daim hlau nrog ib tug specification ntawm 14 - 36 hli, tswj-kub dov yog saws, nrog rau pib kub ntawm tag dov ntawm 950 degree, thiab dej txias rau 670 - 750 degree .

Hauv kev xaus, tsuas yog ua raws li cov kev cai tshwj xeeb ntawm kev ua tiav cov qauv kev ua haujlwm tuaj yeem ua tau zoo thiab kev ua haujlwm ntawm LR AH36 shipbuilding steel daim hlau ua tau raws li qhov yuav tsum tau ua ntawm kev tsim kho nkoj. Hauv cov haujlwm tshwj xeeb, cov ncauj lus kom ntxaws yuav tsum tau ua rau muaj feem cuam tshuam rau kev faib tawm hauv zej zog cov ntsiab lus thiab cov ntaub ntawv kev tshaj lij.
