Shipbuilding Steel Phaj AB EH36

Kev pabcuam: Sandblasting thiab primer

Lub cev muaj zog ua rau muaj teeb meem ntxiv. Lub zog tensile tsis txaus yog ib qho kev txhawj xeeb tsis tu ncua. Thaum lub zog tensile ntawm lub phaj hlau tsis txaus, nws yuav raug puas tsuaj thaum raug kev quab yuam tseem ceeb, uas yog ib qho teeb meem tseem ceeb rau kev ncaj ncees ntawm lub nkoj. Kev tawm dag zog lub zog tsis ua raws li cov qauv tuaj yeem ua rau muaj kev ruaj ntseg ntawm cov qauv raws li nws qhia txog lub ntsiab lus uas cov khoom pib deform mus tas li. Qhov qis elongation tus nqi implies tsis zoo ductility, ua rau muaj kev pheej hmoo ntawm brittle fractures. Hardness uas siab dhau los yog qis dhau tuaj yeem cuam tshuam rau lub phaj hnav tsis kam thiab muaj peev xwm tiv taus qhov cuam tshuam.

Cov defects saum npoo yog ib qho yooj yim pom tab sis tseem ceeb teeb meem. Cracks, pits, inclusions, los yog laminations tuaj yeem ua rau lub ntsej muag ntawm cov phaj hlau, tab sis lawv qhov cuam tshuam mus deb tshaj qhov zoo nkauj. Cov kab nrib pleb tuaj yeem nthuav tawm hauv kev ntxhov siab, ua rau lub zog ntawm cov phaj tsis muaj zog. Pits thiab inclusions tuaj yeem ua raws li cov ntsiab lus kev ntxhov siab, pib ua tsis tiav hauv kev thauj khoom. Laminations tuaj yeem ua rau delamination ntawm cov phaj txheej, txo nws cov peev txheej tag nrho.

Internal defects feem ntau zais ntau dua thiab nyuaj kom pom. Pores, looseness, thiab incomplete welding nkag mus yog ib qho teeb meem sab hauv. Cov teeb meem no tsis yooj yim pom ntawm qhov muag liab qab thiab feem ntau yuav tsum muaj kev sim siab uas tsis muaj kev puas tsuaj xws li kev sim ultrasonic, kev tshuaj xyuas cov khoom sib nqus, lossis kuaj hluav taws xob. Pores tuaj yeem txo qhov ntom thiab lub zog ntawm cov khoom, thaum looseness tuaj yeem cuam tshuam qhov homogeneity thiab tag nrho zoo. Tsis tiav vuam nkag tuaj yeem ua rau cov pob qij txha tsis muaj zog, ua rau muaj kev pheej hmoo ntawm kev ua tsis tiav ntawm cov kev sib tshuam tseem ceeb.

Weldability yog ib qho tseem ceeb uas tuaj yeem tsim teeb meem yog tias tsis muaj qhov sib npaug. Weldability tsis zoo tuaj yeem ua rau kev tsim cov vuam tawg thaum lub sijhawm vuam txheej txheem. Cov kab nrib pleb no tuaj yeem nthuav tawm thiab cuam tshuam qhov kev ncaj ncees ntawm kev sib koom ua ke welded. Lub zog weld tsis txaus tuaj yeem ua rau qhov kev sib txuas tsis ruaj khov, cuam tshuam rau tag nrho cov qauv kev ruaj ntseg ntawm lub nkoj.

Cov txheej txheem tsim khoom kuj tseem ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov zoo ntawm cov phaj steel. Kev tswj tsis zoo ntawm kev kho cua sov thiab lub sijhawm ntev tuaj yeem ua rau tsis sib haum xeeb microstructure thiab txhua yam khoom. Tsis sib xws dov tuaj yeem ua rau muaj kev hloov pauv hauv cov tuab thiab cov khoom siv kho tshuab thoob plaws lub phaj, qhia qhov tsis muaj zog thiab cov ntsiab lus tsis ua haujlwm.

Txhawm rau kom ntseeg tau qhov zoo ntawm Shipbuilding Steel Phaj AB EH36 ua raws li cov qauv nruj thiab cov kev cai ntawm kev tsim nkoj, nws yog ib qho tseem ceeb uas yuav tsum tau ceev faj txog cov teeb meem no thaum lub sij hawm soj ntsuam zoo. Cov txheej txheem kev soj ntsuam nruj me ntsis, kev siv cov cuab yeej tshuaj ntsuam xyuas qib siab, thiab cov kws tshaj lij ntawm cov kws tshuaj ntsuam xyuas tsim nyog yog qhov tseem ceeb hauv kev txheeb xyuas thiab daws cov teeb meem tam sim no. Tsuas yog los ntawm kev tswj hwm qib siab ntawm kev tswj hwm zoo tuaj yeem lav qhov kev nyab xeeb thiab kev ntseeg siab ntawm cov nkoj tsim siv cov khoom tseem ceeb no.

Qhov zoo ntawm Shipbuilding Steel Phaj AB EH36 tsis yog tsuas yog ib qho teeb meem ntawm cov kev qhia tshwj xeeb xwb tab sis kuj yog qhov teeb meem ntawm kev nyab xeeb thiab kev ua neej nyob ntev hauv qhov hnyav marine ib puag ncig. Txhua yam ntawm cov txheej txheem tshuaj xyuas zoo yuav tsum tau ua tiav nrog kev ua tiav thiab kev mob siab rau kev tiv thaiv kev ncaj ncees ntawm cov nkoj thiab lub neej ntawm cov neeg caij nkoj.
