Cov cuab yeej cuab tam thiab kev saib xyuas ntawm CCS Nkoj Hlau Phaj DH36
CCS Nkoj Hlau Phaj DH36 yog dav siv hauv kev lag luam nkoj tsim vim nws cov khoom siv zoo heev thiab ua haujlwm ntev. Cia peb tshawb xyuas cov khoom no thiab kev saib xyuas kom ntxaws.
Cov khoom siv kho tshuab ntawm CCS Ship Steel Phaj DH36 yog qhov tseem ceeb tshaj plaws rau kev ua kom muaj kev ncaj ncees thiab kev nyab xeeb ntawm cov nkoj. Lub zog tawm los ntawm cov phaj hlau no feem ntau yog li ntawm 355 txog 490 MPa, muab qhov tsim nyog tiv thaiv deformation nyob rau hauv load. Qhov no txhais tau hais tias lub phaj tuaj yeem tiv taus kev ntxhov siab tseem ceeb yam tsis muaj kev hloov pauv mus tas li.
Lub zog tensile ntawm DH36 feem ntau nyob nruab nrab ntawm 490 thiab 620 MPa, qhia tias nws muaj peev xwm tiv thaiv kev tawg thaum raug rub tawm. Lub elongation ntawm kev tawg, ib qho kev ntsuas ntawm cov khoom ductility, feem ntau tshaj 20%, tso cai rau cov hlau deform rau ib yam dab tsi ua ntej fracturing. Qhov ductility no yog qhov tseem ceeb hauv kev nqus lub zog thaum lub sij hawm thauj khoom dynamic, xws li cov uas tau ntsib los ntawm cov nkoj hauv hiav txwv.
Qhov cuam tshuam toughness ntawm CCS Ship Steel Phaj DH36 yog lwm yam khoom tseem ceeb. Ntawm qhov kub thiab txias, feem ntau yog -40 degree, cov hlau tuav ib theem ntawm kev cuam tshuam, ua kom nws cov kev ua tau zoo nyob rau hauv ib puag ncig hnyav marine. Qhov cuam tshuam lub zog nqus tau nyob rau hauv cov xwm txheej no feem ntau tau teev tseg tias yog tus nqi tsawg kawg nkaus, xws li 27 J nyob rau hauv qhov kev taw qhia longitudinal thiab 18 J nyob rau hauv txoj kev transverse.
Nyob rau hauv cov nqe lus ntawm hardness, DH36 feem ntau muaj ib tug Rockwell hardness tus nqi nyob rau hauv ib tug tshwj xeeb ntau yam, nyob ntawm seb lub tshav kub kev kho mob thiab ua tej yam kev mob. Qhov hardness no ua rau nws hnav tsis kam thiab muaj peev xwm tiv taus kev puas tsuaj.

Tam sim no, cia peb tig mus rau kev saib xyuas ntawm CCS Nkoj Hlau Phaj DH36. Kev saib xyuas kom zoo yog qhov tseem ceeb los ua kom lub neej ntev thiab khaws cov khoom siv hluav taws xob ntawm cov hlau phaj nyob rau hauv ib puag ncig marine.
Kev tshuaj xyuas tsis tu ncua yog ib qho tseem ceeb ntawm kev saib xyuas. Kev kuaj pom pom yuav tsum tau ua kom pom cov cim ntawm corrosion, tawg, lossis lwm yam kev puas tsuaj ntawm lub phaj. Kev saib xyuas tshwj xeeb yuav tsum tau them rau cov cheeb tsam uas nyiam hnav thiab tsim kua muag, xws li cov npoo thiab cov pob qij txha.
Kev tiv thaiv corrosion yog qhov tseem ceeb tshaj plaws. Txhawm rau tiv thaiv cov hlau los ntawm corrosive los ntawm cov dej ntsev, kev siv cov tshuaj tiv thaiv corrosion yog tsim nyog. Cov coatings no ua raws li kev thaiv, tiv thaiv kev sib cuag ncaj qha ntawm cov hlau thiab nruab nrab corrosive. Hom thiab thickness ntawm txheej yuav tsum raug xaiv raws li cov kev khiav hauj lwm tshwj xeeb thiab lub neej ntev ntawm lub nkoj.
Kev ntxuav lub phaj hlau kuj tseem ceeb heev. Cov khib nyiab, ntsev deposits, thiab lwm yam kab mob yuav tsum tau muab tshem tawm sai li sai tau kom tsis txhob muaj zog corrosion. Qhov no tuaj yeem ua tiav los ntawm kev ntxuav lub siab los yog siv cov tshuaj ntxuav kom tsim nyog.
Welded pob qij txha xav tau kev saib xyuas tshwj xeeb thaum kho. Lawv yuav tsum tau kuaj xyuas kom pom tias muaj kev tawg lossis qaug zog. Periodic re-welding lossis reinforcement tej zaum yuav tsim nyog los xyuas kom meej qhov kev ncaj ncees ntawm cov qauv.
