Astm A131 Nkoj Lub Tsev Hlau Phaj

 

Cov qauv tshuaj ntsuam xyuas rau nkoj tsim cov hlau phaj feem ntau suav nrog cov hauv qab no:
I. Kev tshuaj xyuas qhov tshwm sim
Nto zoo: Txheeb xyuas seb lub npoo ntawm lub phaj hlau puas tiaj tus thiab tsis muaj qhov tsis xws luag xws li tawg, npuas, khawb, quav, thiab slag inclusions. Qhov saum npoo yuav tsum huv si thiab tsis muaj kuab paug xws li roj stains thiab xeb.
Dimensional raug: Ntsuas qhov tuab, dav, ntev thiab lwm qhov ntev ntawm cov phaj steel los xyuas seb lawv puas ua tau raws li tus qauv xav tau. Qhov sib txawv me me yuav tsum nyob rau hauv qhov kev tso cai.
Ntug zoo: Txheeb xyuas seb cov npoo ntawm cov phaj hlau zoo li cas thiab tsis muaj qhov tsis xws luag xws li serrations thiab tawg. Cov npoo yuav tsum du thiab tsis muaj burrs.
II. Tshuaj ntsuam xyuas muaj pes tsawg leeg
Cov ntsiab lus tseem ceeb: Txheeb xyuas cov ntsiab lus ntawm cov ntsiab lus tseem ceeb xws li carbon (C), silicon (Si), manganese (Mn), sulfur (S), thiab phosphorus (P) hauv cov phaj hlau kom ntseeg tau tias lawv ua tau raws li cov qauv kev cai. Cov ntsiab lus ntawm cov ntsiab lus no yuav cuam tshuam rau lub zog, toughness, vuam kev ua tau zoo, thiab lwm yam ntawm steel phaj.
Alloying ntsiab: Rau shipbuilding steel daim hlau uas muaj alloying ntsiab, cov ntsiab lus ntawm alloying ntsiab xws li npib tsib xee (Ni), chromium (Cr), molybdenum (Mo), thiab lwm yam. Qhov sib ntxiv ntawm cov ntsiab lus alloying tuaj yeem txhim kho corrosion kuj thiab lub zog ntawm steel phaj.

 

Yam khoom	Carbon structural steel phaj
Taw qhia	Carbon structural steel plate refers to carbon steel with less than 0.8% carbon. This kind of steel contains less sulfur, phosphorus and non-metallic inclusions than carbon structural steel, and has better mechanical properties. Carbon structural steel can be divided into three categories according to different carbon content: low carbon steel (C≤0.25%), medium carbon steel (C is 0.25-0.6%) and high carbon steel (C>0.6%).
Raws li cov ntsiab lus sib txawv ntawm manganese, carbon structural steel tau muab faib ua ob pawg: cov ntsiab lus manganese ib txwm (manganese {{0}}.25%-0.8%) thiab ntau dua manganese cov ntsiab lus (manganese 0.70%{ {6}}.20%). Cov tom kawg muaj cov khoom siv kho tshuab zoo dua. Thiab kev ua tau zoo.

Dav: 0.6m-3m, lossis raws li xav tau
Nto	Ntxuav, blasting thiab pleev xim raws li cov neeg siv khoom xav tau.
Daim ntawv thov	Muaj ntau yam siv thiab muaj nyiaj ntau. Nws yog tsuas yog siv nyob rau hauv railways, txuas hniav, thiab ntau yam kev tsim kho tej yaam num los tsim ntau yam hlau Cheebtsam uas dais static loads, raws li zoo raws li cov khoom siv tsis tseem ceeb thiab feem ntau welded qhov chaw uas tsis xav tau kev kho cua sov. Feem ntau yog siv rau vuam, riveting, thiab bolting kub-kuav los tiag steel daim hlau, steel strips, seem steels thiab steel tuav rau engineering lug.
Daim ntawv pov thawj	ISO, SGS, BV.
Pob	Txheem export pob, los yog raws li xav tau.

III.Nondestructive testing:
Kev kuaj ultrasonic: Siv cov yam ntxwv nthuav tawm ntawm ultrasonic nthwv dej hauv cov phaj hlau los xyuas seb puas muaj qhov tsis xws luag hauv cov phaj hlau, xws li cov kab nrib pleb thiab kev suav nrog. Ultrasonic kuaj yog ib qho ntawm feem ntau siv nondestructive xeem txoj kev rau shipbuilding steel daim hlau. Nws muaj qhov zoo ntawm kev tshawb nrhiav ceev ceev, siab precision, thiab tsis muaj teeb meem rau tib neeg lub cev.
Magnetic particle testing: Tsim nyog rau kev kuaj xyuas qhov tsis xws ntawm qhov chaw thiab nyob ze ntawm lub phaj steel. Los ntawm kev thov cov hlau nplaum rau ntawm qhov chaw ntawm cov hlau phaj thiab tom qab ntawd nchuav cov hmoov sib nqus, ua tib zoo saib xyuas qhov kev faib tawm ntawm cov hmoov sib nqus los txiav txim seb puas muaj qhov tsis xws luag. Kev ntsuam xyuas cov khoom sib nqus muaj qhov zoo ntawm kev ua haujlwm yooj yim thiab tus nqi qis, tab sis nws tsuas tuaj yeem kuaj xyuas qhov chaw thiab qhov ze ntawm qhov chaw.
Kev kuaj hluav taws xob: Siv X-rays lossis gamma rays kom nkag mus rau cov phaj hlau kom pom qhov tsis xws luag. Kev ntsuam xyuas hluav taws xob muaj qhov ntsuas qhov tseeb, tab sis nws muaj tus nqi siab thiab qee yam kev phom sij rau tib neeg lub cev. Kev kuaj hluav taws xob feem ntau yog siv los kuaj xyuas qhov tseem ceeb lossis ua ntxiv rau lwm txoj kev kuaj tsis zoo.
