Yam twg ntawm Q355 profile yuav tsum tau siv rau tus ncej ntawm lub tsheb thauj neeg mob, thiab vim li cas?
Teb: Q355B / C square / round tube profiles (kev qhia tshwj xeeb: 20 × 20mm ~ 40 × 40mm, phab ntsa tuab 1.5-3mm) yog nyiam. Yog vim li cas: Square / round tubes muaj cov yam ntxwv rigidity siab thiab muaj zog load- bearing peev xwm, haum rau lub dynamic load ntawm kev kho mob trolley; cov profiles yog ua tiav ua ntej, tsuas yog txiav thiab vuam thaum ua, txhim kho kev tsim khoom; 1.5-3mm phab ntsa thickness sib npaug lub zog thiab lub teeb yuag, ua kom yooj yim rau cov neeg ua haujlwm kho mob thawb.
Q355 puas tuaj yeem siv rau lub tsev ntawm cov khoom siv hauv tsev kho mob lub chaw muab tshuaj tua kab mob?
A: Yog, tab sis ob yam yuav tsum tau ua raws li: ① Siv Q355C / D qib, uas muaj cov sulfur thiab phosphorus cov ntsiab lus tsawg thiab zoo dua weldability thiab toughness; ② Lub plhaub saum npoo yuav tsum tau electrophoretically coated nrog cov txheej thickness Ntau dua los yog sib npaug ntawm 60μm kom tiv taus qhov corrosion me ntsis los ntawm siab - qhov kub thiab txias chlorine - muaj cov tshuaj tua kab mob hauv qhov chaw kom tsis muaj menyuam; Yog tias lub plhaub tau los rau hauv kev sib cuag nrog cov dej kho mob, yuav tsum muaj 304 stainless hlau hauv ob sab phlu, thiab Q355 tsuas yog yuav tsum tau siv rau sab nraud load-cov kabmob plhaub.
Hauv kev lag luam kho mob, Q355 puas tuaj yeem hloov Q235 rau cov khoom siv, thiab yuav tsum tau ceev faj dab tsi?
A: Nws tuaj yeem hloov Q235 tag nrho, thiab nws qhov kev ua tau zoo dua; Nco ntsoov peb lub ntsiab lus hauv qab no: ① Q355 muaj zog dua, yog li cov cuab yeej txiav tsim nyog (xws li cov cuab yeej carbide) yuav tsum tau siv thaum lub tshuab ua kom tsis txhob hnav cov cuab yeej ntau dhau; ② Matching vuam hlau (ER50-6) yuav tsum tau siv thaum vuam; Q235 vuam cov ntaub ntawv tsis tuaj yeem siv ncaj qha; ③ Yog tias tus qauv tsim qauv siv Q235, hloov nws nrog Q355 tuaj yeem txo cov phab ntsa tuab, txo cov khoom hnyav, thiab txhim kho tus nqi zoo.
Rau kev txhawb nqa kev kho mob (xws li IV sawv ntsug thiab cov khoom siv tshuaj ntsuam xyuas) hauv cov tsev kho mob sab nraum zoov, qib twg ntawm Q355 stainless hlau thiab kev kho saum npoo yuav tsum raug xaiv?
Teb: Q355D qib nrog kub-dip galvanizing yuav tsum raug xaiv. Q355D tuaj yeem tiv taus kev hloov pauv sab nraum zoov ntawm qhov kub thiab txias, thiab muaj qhov zoo toughness thiab cov qauv ruaj khov. Lub zinc txheej thickness ntawm kub -dip galvanizing yog ntau dua los yog sib npaug rau 85μm, uas yog resistant rau sab nraum zoov los nag thiab plua plav corrosion. Kev pabcuam lub neej ntawm kev txhawb nqa yog ntau dua lossis sib npaug li 10 xyoo, tsis tas yuav tsum tau saib xyuas ntau zaus.
Dab tsi yog cov qauv tsim qauv rau Q355 cov khoom siv hauv cov khoom siv kho mob?
Teb: Cov ntsiab cai tseem ceeb yog **"tsis yog-kev sib cuag nrog tib neeg lub cev, lub zog sib piv, kev ua raws li qhov tseeb, thiab ib puag ncig traceability"**. Tshwj xeeb: ① Txhua Q355 cov khoom siv hauv tsev yuav tsum tsis txhob nkag mus rau tib neeg lub cev lossis cov kua dej kho mob; ② Lub zog tsim yuav tsum muaj qhov muaj kev nyab xeeb txaus (feem ntau Ntau dua lossis sib npaug li 1.5) kom ua tau raws li cov khoom thauj -cov kabmob, kev vibration, thiab cov kev xav tau ntawm kev siv cov khoom siv sij hawm ntev -; ③ Dimensional precision thiab geometric tolerances yuav tsum tau yoog raws li cov kev cai sib dhos ntawm cov khoom siv kho mob; ④ Tag nrho cov txheej txheem yuav tsum ua kom tau raws li qhov yuav tsum tau muaj kev tiv thaiv ib puag ncig thiab kev taug qab, thiab ua tau raws li tag nrho -tsim ntawv pov thawj thiab kev tswj kom zoo.
