Puas muaj cov qauv hauv tebchaws lossis kev lag luam tshwj xeeb rau Q355 steel siv hauv kev lag luam kho mob?
A: Tam sim no, tsis muaj cov qauv tshwj xeeb rau Q355 steel siv hauv kev lag luam kho mob. Nws yog raws li GB / T 1591-2018 "Low Alloy High Strength Structural Steel" thiab yuav tsum ua kom tau raws li lub zog, ruaj khov, thiab ib puag ncig cov kev cai rau cov khoom siv hauv kev lag luam rau cov khoom siv kho mob kom tiav (xws li GB 9706.1 "Cov Khoom Siv Kho Mob Hluav Taws Xob Part 1: Cov Kev Xav Tau rau Kev Nyab Xeeb thiab Kev Ua Haujlwm Zoo").
Vim li cas Q355A tsis tshua siv hauv kev lag luam kho mob?
A: Q355A tsis muaj qhov yuav tsum tau ua kom tawv nqaij, thiab nws qhov kev txwv sab sauv rau cov khoom tsis zoo xws li sulfur thiab phosphorus siab dua li qib B / C / D. Nws yog qhov ua rau txias brittleness thiab welding tawg thaum lub sij hawm ua, uas ua rau tsis zoo structural stability. Cov cuab yeej kho mob muaj qhov xav tau siab heev rau kev nyab xeeb kev ua haujlwm, thiab cov khoom siv hauv tsev yuav tsum tiv taus qhov cuam tshuam ntawm kev thauj mus los, kev teeb tsa, thiab kev siv sijhawm ntev -. Yog li, Q355A tsis tshua xaiv.
Dab tsi yog cov kev cai sib nqus rau Q355 steel siv hauv cov khoom siv kho mob (CT / MRI)?
A: Cov khoom siv MRI muaj qis / tsis yog{0}} cov kev cai sib nqus rau cov khoom siv nyob ib puag ncig. Ordinary Q355 yog cov khoom siv ferromagnetic thiab tsis tuaj yeem siv ncaj qha rau hauv cov khoom siv hauv MRI. Kev hloov kho qis- sib nqus Q355 nrog kev ua haujlwm tshwj xeeb tuaj yeem siv tau (cov ntsiab lus ferrite yuav tsum tau tswj kom txo qis permeability), lossis Q355 zoo tib yam tuaj yeem siv tsuas yog hauv cov qauv kev txhawb nqa peripheral ntawm cov khoom siv MRI (tsawg kawg 1.5m ntawm thaj chaw hlau nplaum). Cov cuab yeej CT tsis muaj qhov nruj qis- cov kev cai sib nqus, thiab Q355B / C / D zoo ib txwm siv tau.
Lub toughness ntawm Q355 puas tuaj yeem ua tau raws li qhov dynamic load-cov kev cai ntawm lub rooj ua haujlwm?
A: Yog. Cov rooj ua haujlwm yuav tsum tiv taus cov khoom hnyav los ntawm kev ua haujlwm ntawm cov neeg ua haujlwm kho mob, tus neeg mob hnyav, thiab cov khoom siv intraoperative. Q355C / D stainless hlau muaj qhov cuam tshuam lub zog Ntau dua lossis sib npaug ntawm 34J ntawm chav tsev kub (Hom V) thiab tseem siab dua lossis sib npaug rau 34J ntawm -20℃(Class D), nrog cov yas elongation Ntau dua lossis sib npaug li 20%. Nws pom tias tsis muaj kev pheej hmoo ntawm cov yas deformation los yog tawg nyob rau hauv dynamic load. Nrog rau kev tsim qauv tsim nyog, nws tuaj yeem ua tau raws li qhov xav tau ntawm kev ua haujlwm ntawm cov rooj ua haujlwm (cov qauv tsim qauv muaj peev xwm ntau dua lossis sib npaug li 200kg).
Q355 stainless hlau puas tuaj yeem siv rau sab nrauv ntawm cov khoom siv tshuaj tua kab mob tiv thaiv me ntsis ntawm cov tshuaj tua kab mob ib puag ncig?
Teb: Ordinary Q355 stainless hlau tsis yog corrosion-resistant. Qhov chaw ib puag ncig ntawm cov khoom siv tshuaj tua kab mob muaj me ntsis corrosion los ntawm cawv, chlorine - muaj cov tshuaj tua kab mob, thiab vapors, ua rau nws yooj yim rau xeb yog siv ncaj qha. Q355 casing xav tau qhov chaw tiv thaiv- kev kho corrosion (xws li electrostatic hmoov txheej, electrophoresis, lossis galvanizing). Tom qab kev kho mob, nws tuaj yeem tiv taus qhov corrosion me ntsis ntawm cov pa tshuaj tua kab mob ib puag ncig thiab ua tau raws li cov khoom siv lub neej ua haujlwm (feem ntau Ntau dua lossis sib npaug li 5 xyoos).
