Khoom Description
Lub phaj "zoo tshaj" nkoj tsim tuaj yeem sib txawv raws li cov kev xav tau tshwj xeeb thiab cov ntawv thov scenarios. Nov yog qee qhov feem ntau pom zoo shipbuilding daim hlau:
AH36 / DH36 / EH36 steel phaj:
Lub zog thiab mechanical zog: Cov no yog cov txheej txheem steel phaj uas siv dav hauv kev tsim cov nkoj. Lawv muaj cov khoom siv zoo heev, nrog lub zog tensile siab thiab zoo ductility, ua rau lawv tsim nyog rau kev tsim kho ntawm ntau hom nkoj. Lawv tuaj yeem tiv taus cov khoom hnyav thiab kev ntxhov siab uas tau ntsib los ntawm cov nkoj thaum lub sijhawm ua haujlwm, ua kom muaj kev ncaj ncees ntawm lub nkoj.
Weldability: Lawv kuj muaj qhov zoo weldability, uas yog ib qho tseem ceeb heev rau kev tsim khoom hauv nkoj vim vuam yog ib qho kev sib sau ua ke ntawm nkoj nkoj. Zoo weldability tso cai rau kev tsim kho ntawm lub nkoj kom zoo thiab ua kom zoo ntawm cov pob qij txha welded.
ABS Qib A / B Steel Phaj:
Lub zog thiab corrosion kuj: Muab los ntawm American Bureau of Shipping, cov phiaj no muab lub zog zoo thiab feem ntau muab nrog kev txhim kho corrosion. Qhov no yog ib qho tseem ceeb rau cov nkoj uas niaj hnub raug dej hiav txwv thiab cov dej hiav txwv hnyav, vim nws yuav pab kom lub neej ntev ntawm lub nkoj thiab txo cov nqi tu.
Lloyds Qib A / B Steel Phaj:
Tensile zog thiab toughness: Lloyds Register of Shipping qhia cov qib ntawm cov hlau phaj rau nkoj tsim. Lawv paub txog lawv lub zog tensile siab thiab zoo toughness zog, uas ua rau lub nkoj tiv taus ntau yam dynamic loads thiab cuam tshuam thaum lub sij hawm kev pab cuam lub neej.

Cov kev sim hardness rau high-strength shipbuilding steel daim hlau mas muaj xws li cov hauv qab no:
I. Brinell hardness test
Kev sim txoj cai:
Siv lub pob tawv tawv ntawm ib txoj kab uas hla los nias rau saum npoo ntawm cov qauv nrog lub zog ntsuas. Tom qab lub sijhawm tuav, tshem tawm lub zog ntsuas thiab ntsuas lub cheeb ntawm qhov indentation ntawm tus qauv nto.
Xam cov Brinell hardness value (HBW) los ntawm qhov indentation txoj kab uas hla. Cov mis yog HBW=F / (πD(D - √(D² - d²))), qhov twg F yog qhov kev xeem quab yuam, D yog lub cheeb ntawm lub indenter, thiab d yog qhov nruab nrab txoj kab uas hla ntawm indentation.
Scope ntawm kev siv:
Brinell hardness test yog haum rau high-strength shipbuilding steel daim hlau ntawm qhov ntau thiab tsawg. Vim nws qhov indentation loj dua, nws tuaj yeem cuam tshuam tag nrho cov yam ntxwv hardness ntawm cov khoom.
Rau cov ntaub ntawv tsis sib xws, Brinell hardness test kuj tuaj yeem muab cov txiaj ntsig zoo.
Qhov zoo:
Lub zog xeem yog loj thiab qhov chaw indentation yog loj. Nws tuaj yeem cuam tshuam qhov nruab nrab hardness ntawm cov khoom nyob rau hauv ntau yam. Cov txiaj ntsig yog qhov tseeb thiab ruaj khov.
Qhov yuav tsum tau rau qhov roughness ntawm cov khoom nto yog qhov tsawg.
Qhov tsis zoo:
Cov txheej txheem kuaj no kuj cumbersome thiab yuav tsum tau siv sij hawm ntev thiab tus qauv loj.
Lub indentation kuj loj heev thiab tej zaum yuav ua rau tej yam kev puas tsuaj rau tus qauv.
