Cov kev ntsuas tseem ceeb los xyuas kom meej qhov zoo ntawm L360 steel kav muaj xws li cov hauv qab no:
Kev kuaj tshuaj muaj pes tsawg leeg
Kev tshuaj xyuas nruj me ntsis ntawm cov khoom siv raw ntawm L360 cov kav hlau steel kom ntseeg tau tias cov ntsiab lus ntawm txhua lub ntsiab lus ua tau raws li cov qauv. Piv txwv li, cov ntsiab lus carbon yuav tsum tsawg dua lossis sib npaug rau 0.26% (welded) lossis Tsawg dua lossis sib npaug rau 0.28% (seamless), cov ntsiab lus manganese yuav tsum tsawg dua lossis sib npaug li 1.40%, thiab cov ntsiab lus phosphorus thiab sulfur yuav tsum tsawg dua lossis sib npaug li 0.030%. Cov cuab yeej tshuaj ntsuam xyuas kev tshaj lij thiab cov txheej txheem yog siv los txiav txim siab qhov kev faib ua feem ntawm txhua lub ntsiab lus thiab tswj cov yeeb nkab steel zoo los ntawm qhov chaw.
Mechanical Properties Test
Tensile Test: Ntsuas lub zog tawm los, lub zog tensile thiab elongation ntawm cov yeeb nkab steel. L360 Lub zog tawm los ntawm cov yeeb nkab steel yuav tsum siab dua lossis sib npaug ntawm 360Mpa, lub zog tensile Ntau dua lossis sib npaug rau 460Mpa, thiab qhov elongation Ntau dua lossis sib npaug rau qee yam nqi. Cov qauv yog ncab los ntawm lub tshuab ntsuas tensile kom tau txais cov ntaub ntawv tseem ceeb ntawm cov khoom siv los ntsuas qhov kev ua tau zoo ntawm cov yeeb nkab steel thaum raug nro.
Impact test: Impact test test yog ua los kuaj qhov cuam tshuam ntawm cov yeeb nkab steel nyob rau hauv qhov sib txawv ntawm qhov kub thiab txias kom ntseeg tau tias nws tuaj yeem tiv taus qhov cuam tshuam rau kev siv tiag tiag thiab tsis txhob tawg tawg.
Dimensional raug kuaj pom
Siv cov cuab yeej ntsuas kom raug ntsuas cov kab sab nraud, phab ntsa thickness, ntev thiab lwm qhov ntev ntawm cov yeeb nkab steel los xyuas kom meej tias nws qhov sib txawv ntawm qhov sib txawv yog nyob rau hauv qhov kev tso cai thiab ua tau raws li cov qauv tsim thiab cov qauv tsim qauv los xyuas kom meej tias cov hlau sib txuam thiab sib khi. cov yeeb nkab thaum lub sij hawm installation thiab siv.
Kev tshuaj xyuas qhov zoo
Siv kev tshuaj xyuas qhov muag, kev tshuaj xyuas cov khoom sib nqus, kev tshuaj xyuas tam sim no thiab lwm txoj hauv kev los xyuas seb puas muaj cov kab nrib pleb, qhov pores, slag inclusions, khawb thiab lwm yam tsis xws luag ntawm cov yeeb nkab steel. Rau cov kav hlau uas muaj kev tiv thaiv corrosion, qhov zoo thiab tuab ntawm cov txheej txheem tiv thaiv corrosion yuav tsum tau kuaj xyuas kom ntseeg tau tias qhov zoo ntawm cov yeeb nkab steel yog qhov zoo thiab tuaj yeem tiv taus qhov yaig ntawm qhov chaw sab nraud.
Kev kuaj tsis muaj kev puas tsuaj
Kev kuaj ultrasonic: Siv cov kev xav thiab kev cuam tshuam ntawm ultrasonic nthwv dej thaum propagating hauv cov yeeb nkab steel, xyuas seb puas muaj qhov tsis xws luag hauv cov yeeb nkab steel, xws li cov kab nrib pleb, qhov, thiab lwm yam. qauv.
Kev ntsuas hluav taws xob: X-rays lossis -rays nkag mus rau hauv cov yeeb nkab steel kom pom cov qauv sab hauv, intuitively tso saib cov teeb meem hauv cov yeeb nkab steel, thiab muab lub hauv paus txhim khu kev qha rau kev soj ntsuam zoo.
Cov txheej txheem kuaj
Nyob rau hauv cov txheej txheem ntawm cov yeeb nkab steel, xws li steelmaking, dov, kho cua sov thiab lwm yam kev sib txuas, teeb tsa cov ntsiab lus txheeb xyuas, saib xyuas cov txheej txheem tsis zoo thiab cov khoom lag luam zoo hauv lub sijhawm, kho thiab kho cov txheej txheem ntau lawm hauv lub sijhawm, xyuas kom meej tias txhua tus txheej txheem ua tau raws li qhov xav tau. cov kev xav tau zoo, thiab yog li ua kom muaj kev ruaj ntseg zoo ntawm cov khoom kawg.
