Sa516Gr60 yog tsim tawm hauv cov hluav taws xob kom tawg los ntawm cov ntaub pua tsev hluav taws los ntawm cov steel hlau, ua rau cov hlau ntshiab. Lub phaj yog tsim los ntawm poling hlau nplaum, txias nws, thiab nias nws mus rau hauv ib daim ntawv tiaj tus. Lub tiaj tus, lub voos plaub hau tuaj yeem dov ncaj qha lossis txiav los ntawm cov hlau sib tw. Steel phaj yog catalorized los ntawm tuab raws li nram no: nyias phaj<8 mm (thinnest 0.2 mm), medium-thick plate 8-60 mm, and extra-thick plate 60-120 mm.
Sa516Gr60 steel phaj loj, qhov hnyav, thiab kev ua kom muaj kev zam txim:
Qhov ntev, cov duab, thiab kev ua kom muaj txiaj ntsig ntawm cov hlau phaj yuav tsum ua raws li cov qauv hauv tebchaws.
Lub thickness kam kam rau ntawm cov phaj steel yuav tsum ua raws li chav kawm b kev ua phem ntawm GB / T709. Thaum thov txog, lub phaj yuav xa nrog chav kawm C thev GB / T709.
SA516Gr60 Tus Kab Mob Hlau Hlau Steel
Thickness -} Cov kev ua tau zoo rau SA516Gr60 steel phaj: Z15, thiab Z35.
Tsis - Qhov Yuav Tsum Tau Txais rau SA516Gr60 Hlau Phaj: Thawj, thiab Tertiary Soj ntsuam.
Z - Kev Taw Qhia Cov Khoom Ntawm Sa516Gr60 Hlau Hlau
1. Dab tsi yog z - kev taw qhia?
Z {-}}}}}}} akellar kua muag tiv thaiv cov hlau, "feem ntau hu ua z {1} kev qhia khoom. Hauv cov qauv hlau txuas nrog welds, thaum lub phaj steel thickness yog 40 mm lossis ntau dua} Lamellar kua muag yog qhov teeb meem nrog cov phiaj tuab, yog li z - kev taw qhia cov khoom kuaj yog qhov tsim nyog.
2. Z {{{1} Kev qhia kev lag luam thiab lawv qhov kev cuam tshuam rau ntawm cov hlau phaj
Cov phiaj tuab hlau feem ntau yog cov ntau dua li ua rau lamellar vim tias qhov tsis muaj teeb meem muaj, thiab cov tuab neeg weld, qhov ntau dua cov vuam kev ntxhov siab thiab deformation. Txhawm rau hais txog qhov teeb meem no, z - kev taw qhia steel yog qhov zoo tshaj plaws siv. Hom hlau no yog tsim los ntawm ib qib kev tshwj xeeb ntawm cov qauv hlau (hu ua niam txiv hlau) thiab undergoes tshwj xeeb smelting thiab kev kho mob. Nws cov lus faj sulfur yog tsawg dua ib - tsib tsib hais txog ntu deminal, thiab nws txo ntawm tshooj yog saum toj 15%. Cov khoom siv mechanical ntawm cov hlau phaj raws nws cov tuab (feem nws ductility) yog hu ua z {8} kev taw qhia khoom. Cov khoom no tuaj yeem txiav txim siab los ntawm kev kuaj mob Tensile ntawm cov hnoos qeev thiab feem ntau ntsuas los ntawm kev txo thaj chaw. Z {{11 11}}}}}}}}}}}}}}}}}} Kev taw qhia cov qib steel qib kev kawm Z25, lossis Z25 tom qab tus niam txiv qib steel. Tus lej tom qab Z sawv cev rau qhov chaw txo qis (%).
SA516Gr60 Hlau Phaj Txiav Tej Txheej Txheem:
Kev txiav txim siab: SA516GR60 steel thoj xyuas thiab, tom qab ntsib txhua qhov kev ua tau zoo, raug txiav raws li cov txheej txheem txiav. Txiav thiab txiav raws li kev kos duab yog tau. Feem ntau, cnc ntshav txiav los yog cnc laser txiav yog qhov xav tau rau daim hlau mus txog 20 hli tuab. Rau cov hlau 30 hli tuab los yog tuab dua, CNC nplaim txiav yog feem ntau siv los tswj cov khoom txiav thiab sijhawm.
