LR Marine Steel Phaj Qib E

LR Marine Steel Phaj Qib E yog hom nkoj tsim steel phaj ntawv pov thawj los ntawm Lloyd's Register.

 

Yam ntxwv:

 

Tshuaj muaj pes tsawg leeg: Nws muaj cov ntsiab lus tshwj xeeb xws li carbon, silicon, manganese, phosphorus, sulfur, thiab kuj tseem tuaj yeem muaj cov lej ntawm cov hlau alloying. Kev tswj cov tshuaj muaj pes tsawg leeg yog tsim los muab cov hlau nrog qee yam khoom siv thiab kev tiv thaiv corrosion.

Mechanical zog: Nws feem ntau muaj qee theem ntawm kev tawm dag zog, lub zog tensile, thiab elongation. Lub zog tawm los txiav txim siab qhov kev ntxhov siab uas cov hlau pib deform plastically. Lub zog tensile qhia tias qhov siab tshaj plaws ntawm cov hlau tuaj yeem tiv taus ua ntej tawg. Lub elongation qhia lub peev xwm ntawm cov hlau kom deform yam tsis muaj fracturing.

Corrosion kuj: Vim nws muaj pes tsawg leeg thiab cov txheej txheem tsim khoom, nws muaj qee qhov kev tiv thaiv corrosion nyob rau hauv marine ib puag ncig. Qhov no yog qhov tseem ceeb rau kev ua kom lub neej ntev thiab kev ncaj ncees ntawm cov nkoj thiab cov qauv hauv hiav txwv.

LR Marine Steel Phaj Qib E muaj qee yam kev tiv thaiv corrosion, uas yog qhov tseem ceeb hauv cov hauv qab no:
Tshuaj muaj pes tsawg leeg tsim:

 

 

Ntxiv ntawm alloying ntsiab: Nws muaj qhov tsim nyog ntawm cov khoom siv alloying xws li manganese thiab silicon. Manganese caij tuaj yeem txhim kho lub zog thiab tawv tawv ntawm cov hlau, thiab tib lub sijhawm txhim kho corrosion kuj ntawm steel rau qee yam. Nws tuaj yeem cuam tshuam nrog cov impurities xws li oxygen thiab sulfur hauv cov hlau los tsim cov khoom sib txuas ruaj khov thiab txo cov nyhuv corrosion ntawm cov impurities ntawm steel. Silicon lub caij tuaj yeem txhim kho oxidation tsis kam thiab acid tsis kam ntawm cov hlau. Nyob rau hauv ib puag ncig marine, nws tuaj yeem tiv taus qhov yaig ntawm dej hiav txwv thiab yaj cov pa oxygen, carbon dioxide thiab lwm yam khoom hauv dej hiav txwv ntawm cov hlau.

Lub luag haujlwm ntawm aluminium element: Cov ntsiab lus aluminium tsis tsawg dua 0.015%. Aluminium tuaj yeem tsim cov xim txhuas oxide tuab ntawm cov hlau. Cov oxide zaj duab xis no muaj kev ruaj ntseg zoo thiab corrosion kuj thiab tuaj yeem tiv thaiv cov pa sab nraud, ya raws thiab lwm yam corrosive los ntawm kev tiv thaiv sab hauv ntawm cov hlau thiab ua lub luag haujlwm hauv kev tiv thaiv hlau.
Kev tswj cov txheej txheem ntau lawm:

Kev tswj xyuas nruj: Thaum lub sij hawm tsim cov txheej txheem, los ntawm kev tswj xyuas nruj thiab kev tshuaj xyuas, xyuas kom meej tias cov tshuaj muaj pes tsawg leeg thiab cov txheej txheem ntawm cov hlau tsis sib xws thiab ruaj khov. Ib qho tshuaj sib xyaw ua ke tuaj yeem ua rau kev txhim kho corrosion ntawm txhua feem ntawm cov hlau nyob ib puag ncig thiab tsis txhob muaj qhov hnyav hauv zos; lub koom haum ruaj khov tuaj yeem txhim kho tag nrho lub zog thiab corrosion tsis kam ntawm cov hlau.

Cov txheej txheem kho deg: Feem ntau, qee qhov kev kho deg xws li kev tshem tawm xeb thiab xuab zeb blasting yog nqa tawm kom tshem tawm cov impurities thiab oxide nplai ntawm cov hlau nto thiab ua rau cov hlau nto du thiab tiaj tus. Ib tug du nto yuav txo tau qhov adhesion thiab tsub zuj zuj ntawm corrosive tshuaj nyob rau hauv steel nto thiab txo qhov tshwm sim tshwm sim ntawm corrosion.
Txawm li cas los xij, cov nyhuv tiv thaiv corrosion ntawm LR Marine Steel Phaj Qib E yog txheeb ze. Nyob rau hauv ib puag ncig marine hnyav rau lub sijhawm ntev, lwm yam kev tiv thaiv corrosion xws li pleev xim, galvanizing, thiab kev tiv thaiv cathodic tseem yuav tsum tau coj los txhim kho kev tiv thaiv corrosion ntawm cov hlau.

LR yog hais txog Lloyd's Register Group Limited, lub koom haum UK siab rau kev tshawb fawb thiab kev kawm hauv science thiab engineering. Nws yog lub koom haum maritime tshwj xeeb.
