Kub Rolled Txheej Txheem Hlau H Nqaj S355JR HEM280
Tus ntoo khaub lig-ntu qhov ntev ntawm HEM280 qauv HAR BAR yog: qhov siab (H) yog 310 lub hli; Flth Dav (B) yog 288 hli; Web tuab (t₁) yog 18,5 hli; Flange tuab (t₂) yog 33 hli.
S355JR Cov Txheej Txheem Hlau H Tsua yog mus rau European txheem qis-alloy High-zog qauv hlau, uas ua raws li lub en {3}} txheem. Cov tshuaj lom neeg muaj pes tsawg leeg ntawm S355jr H Beam khoom siv: carbon (c) tsawg dua lossis sib npaug ntawm {0. toughness.
Cov txiaj ntsig lub zog ntawm s355jr h-nqaj hlau qauv sib txawv nrog cov tuab. Nws yog 355 MPa thaum lub tuab yog tsawg dua lossis sib npaug nrog kev txo qis dua nrog cov tuab 34 {5}} mm); Lub zog tensile yog 470-630 mpa. Qhov kev cuam tshuam nyuaj yog ntau dua lossis sib npaug rau 27 j ntawm +20 degree.
Kev tsim kho cov kws kho vaj tse: Tsim nyog rau cov txheej txheem sib xyaw nrog kev muaj peev xwm ntau xws li txuas hniav thiab cov tsev nce siab.
Kev tsim tshuab: siv rau cov khoom siv xws li cranes thiab kev siv tshuab uas yuav tsum tau tiv thaiv kev qaug zog thiab cuam tshuam.
Lwm cov teb: scenes nrog high cov kev xav rau corrosion tsis kam thiab muaj zog xws li tsheb tsim thiab marine engineering.
Cov Cheeb Tsam Thov ntawm Hem280 (S355JR Beam Steel)
Lub Tsev Cov Qauv: Siv cov nqaj muaj kev nce siab, lub vov ntawm cov nroj tsuag muaj zog thiab lwm cov scenes, cov kabmob ntsug thiab kab rov tav loads.
Choj engineering: haum rau cov qauv qauv ntawm cov choj, choj txiav caj dab, cov kab teeb, cov kabmob tsis muaj zog ntawm cov tsheb thiab ntuj ib puag ncig.
Kev tsim khoom machinery: Kev tsim khoom siv cov tshuab machinery xws li crane booms, excavator chassis, thiab tsuas cov khoom siv chassis, thiab cov khoom siv mining kom muaj zog thiab nkees tsis kam.
Marine Engineering thiab nkoj: raws li cov khoom siv xws li Hull decks, thiab offshore platform trusses, tiv taus dej hiav txwv corrosion thiab yoj.
Zog thiab khoom siv: siv rau hauv cov khoom siv hluav taws xob xws li cua tshuab hluav taws xob yees thiab txhawb nqa hydraulic kom tiv thaiv kev ntxhov siab nyob rau hauv kev ua haujlwm nyuaj.
Tsheb thauj mus los: Siv nyob rau hauv tsheb thauj khoom, kev xa nkoj choj thiab kev ncua tsheb tshuab kom ntseeg tau kev nyab xeeb thiab kev ntseeg tau.
