1.Lub zog tensile (σb): Lub zog siab tshaj plaws (Fb) uas cov qauv ua rau muaj qhov nro thaum nws rub, muab faib los ntawm qhov kev ntxhov siab (σ) tau los ntawm qhov chaw hla ntu ntu (Yog li) ntawm cov qauv, hu ua tensile zog ( σb), hauv N / mm2 (MPa). Nws sawv cev rau lub peev xwm siab tshaj plaws ntawm cov khoom siv hlau los tiv thaiv kev puas tsuaj hauv qhov nro. Qhov twg: Fb - qhov siab tshaj plaws quab yuam cov qauv tiv thaiv thaum nws rub, N (Newton); Yog li - thawj qhov chaw hla ntu ntawm cov qauv, mm2.
2.yield point (σs): cov khoom siv hlau nrog qhov tshwm sim tshwm sim, qhov kev ntxhov siab thaum cov qauv tuaj yeem txuas ntxiv mus ntxiv yam tsis muaj qhov nce hauv qhov quab yuam (tseem nyob twj ywm) thaum lub sij hawm ncab, hu ua yield point. Yog tias lub zog txo qis, cov ntsiab lus sab saud thiab qis dua yuav tsum tau paub qhov txawv. Chav tsev ntawm qhov taw tes tawm yog N / mm2 (MPa). Upper yield point (σsu): qhov siab tshaj plaws ua ntej cov qauv yields thiab lub zog ua ntej txo; Qis yield point (σsl): qhov tsawg kawg nkaus kev ntxhov siab nyob rau hauv lub yielding theem thaum lub sij hawm pib cov nyhuv tsis suav rau. Qhov twg: Fs - yield quab yuam (qhov tsis tu ncua) ntawm cov qauv hauv qhov nro, N (Newton) Yog li - thawj ntu ntu ntawm cov qauv, mm2.
3.elongation tom qab so: (σ) Hauv qhov ntsuas tensile, qhov feem pua ntawm qhov nce ntawm qhov ntev ntawm cov qauv tom qab rub tawm nws cov nplai mus rau qhov ntev ntawm qhov ntsuas thawj yog hu ua elongation. Qhia hauv σ, chav tsev yog %. Qhov twg: L1 - qhov ntev ntawm qhov hnoos qeev tom qab tus qauv raug rub, mm; L0 - qhov ntev ntawm tus qauv lub suab, mm.
4.Fractional shrinkage: (ψ) Hauv kev sim tensile, qhov siab tshaj plaws shrinkage ntawm qhov chaw hla ntu ntawm nws qhov shrinkage tom qab cov qauv raug rub tawm raws li feem pua ntawm qhov qub ntu ntu yog hu ua fractional shrinkage. Qhia ua ψ, hauv %. Qhov twg: S0 - thawj qhov chaw hla ntu ntawm cov qauv, mm2; S1 - qhov tsawg kawg nkaus ntu ntu ntawm qhov shrinkage tom qab cov qauv raug rub tawm, mm2.
5.Hardness Performance index: lub peev xwm ntawm cov khoom siv hlau los tiv thaiv qhov indentation ntawm ib qho khoom tawv rau hauv qhov chaw, hu ua hardness. Nyob ntawm txoj kev sim thiab qhov kev thov, hardness tuaj yeem muab faib ua Brinell hardness, Rockwell hardness, Vickers hardness, Shore hardness, microhardness thiab kub hardness. Rau lub raj feem ntau siv hauv Brinell, Rockwell, Vickers hardness peb.
Brinell hardness (HB): Siv cov hlau los yog carbide pob ntawm ib txoj kab uas hla, nias lub zog ntsuas (F) rau saum npoo ntawm cov qauv, tshem tawm lub zog ntsuas tom qab lub sijhawm tuav, thiab ntsuas qhov indentation txoj kab uas hla (L) nyob rau saum npoo ntawm cov qauv. Tus nqi ntawm Brinell hardness yog qhov quotient tau los ntawm kev faib cov kev xeem quab yuam los ntawm qhov chaw ntawm lub ntsej muag kheej kheej ntawm qhov indentation. Qhia ua HBS (steel pob) hauv N / mm2 (MPa).
Kub-dip galvanized steel kav yog siv dav hauv kev tsim kho, tshuab, thee mining, tshuaj lom neeg kev lag luam, hluav taws xob, tsheb ciav hlau, tsheb kev lag luam, kev loj, txuas hniav, ntim khoom, chaw ua si, kev ua liaj ua teb, roj av machinery, prospecting machinery thiab lwm yam kev lag luam. .
Galvanized steel yeeb nkab yog welded steel yeeb nkab nrog kub dip lossis electro galvanized nto. Galvanization tuaj yeem ua rau muaj kev tiv thaiv corrosion ntawm cov kav hlau thiab ua rau lub neej ntev. Galvanized steel yeeb nkab muaj ntau yam kev siv, nrog rau kev siv los ua cov kav dej rau cov dej tsis tshua muaj xws li dej, roj thiab roj, nws kuj tseem siv tau los ua cov kav dej roj thiab cov kav dej hauv cov roj av, tshwj xeeb tshaj yog nyob rau hauv marine roj teb, raws li ib tug roj rhaub, condensation cooler thiab thee distillation thiab roj ntxuav exchanger rau tshuaj coking khoom, thiab raws li ib tug txhawb thav duab yeeb nkab rau trestle yeeb nkab piles thiab mining pits lwm.
Cov yeeb nkab dej, roj yeeb nkab, cov yeeb nkab scaffolding, laj kab kev loj, lub hau npog, thiab lwm yam.
