Khoom Description
Ntxiv rau qhov ua tau zoo thiab lub zog tensile, cov cuab yeej cuab tam hauv qab no kuj tseem cuam tshuam qhov zoo ntawm LR Marine Steel Phaj Qib A:
I. Impact toughness
Qhov tseem ceeb:
Impact toughness qhia txog lub peev xwm ntawm cov hlau kom nqus tau lub zog thiab tiv thaiv kev puas tsuaj nyob rau hauv kev cuam tshuam loads. Rau cov nkoj tsim steel, nyob rau hauv ib puag ncig marine, nws yuav ntsib ntau yam kev cuam tshuam sai xws li kev cuam tshuam yoj thiab kev sib tsoo. Kev cuam tshuam zoo tuaj yeem ua kom ntseeg tau tias cov phaj hlau tsis tuaj yeem ua rau tawg tawg hauv cov xwm txheej no thiab txhim kho kev nyab xeeb ntawm cov nkoj.
Tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias ib puag ncig, qhov cuam tshuam toughness ntawm hlau tseem ceeb dua. Cov huab cua nyob hauv dej hiav txwv yog qhov nyuaj, thiab cov nkoj tuaj yeem caij nkoj hauv thaj chaw txias. Lub sijhawm no, qhov cuam tshuam toughness ntawm steel yog ncaj qha cuam tshuam rau kev ruaj ntseg ntawm lub nkoj qauv.
Kev cuam tshuam:
Tshuaj muaj pes tsawg leeg: Alloying cov ntsiab lus xws li manganese thiab npib tsib xee hauv hlau tuaj yeem txhim kho kev cuam tshuam toughness. Piv txwv li, tus nqi tsim nyog ntawm manganese tuaj yeem ua kom cov nplej zom thiab ua kom cov tawv nqaij ntawm cov hlau.
Microstructure: Cov qauv zoo ib yam thiab zoo lis pab txhim kho kev cuam tshuam toughness. Los ntawm kev siv cov txheej txheem kho cua sov kom tsim nyog, lub microstructure ntawm hlau tuaj yeem tswj tau los txhim kho qhov cuam tshuam toughness.
Kev suav thiab qhov tsis xws luag: Kev suav nrog thiab qhov tsis xws hauv cov hlau yuav txo cov kev cuam tshuam toughness. Kev tswj hwm cov txheej txheem smelting thiab dov nruj me ntsis tuaj yeem txo cov tiam ntawm kev suav thiab txhim kho cov hlau zoo.
II. Elongation
Qhov tseem ceeb:
Elongation sawv cev rau cov yas deformation muaj peev xwm ntawm cov hlau thaum ncab. Ib qho elongation ntau dua txhais tau hais tias cov hlau tuaj yeem dhau los ua qhov loj deformation yam tsis tau tawg thaum muaj kev ntxhov siab. Qhov no yog qhov tseem ceeb heev rau kev ua thiab siv cov qauv nkoj.
Thaum lub sij hawm tsim cov nkoj, cov hlau phaj yuav tsum tau ua haujlwm xws li khoov thiab stamping. Qhov zoo elongation tuaj yeem ua kom ntseeg tau tias cov phaj hlau tsis tuaj yeem ua rau tawg thiab tawg thaum ua haujlwm. Nyob rau tib lub sijhawm, thaum lub sijhawm ua haujlwm ntawm cov nkoj, cov qauv hull yuav raug rau ntau yam kev thauj khoom. Kev elongation ntau dua tuaj yeem ua rau cov hlau zoo dua rau cov khoom thauj no thiab txhim kho kev ntseeg tau ntawm cov nkoj.
Kev cuam tshuam:
Tshuaj muaj pes tsawg leeg: Steels nrog qis carbon cov ntsiab lus feem ntau muaj elongation zoo dua. Tsis tas li ntawd, ib co alloying ntsiab xws li silicon thiab manganese kuj yuav cuam tshuam elongation.
Rolling txheej txheem: Ib txheej txheem dov tsim nyog tuaj yeem ua rau cov hlau kom tau txais cov yas deformation zoo. Piv txwv li, tswj cov dov kub thiab deformation tus nqi tuaj yeem ua kom zoo dua qhov microstructure ntawm steel thiab txhim kho elongation.
