Dab tsi yog qhov zoo ntawm DX51D + Z100 steel sawb piv rau lwm hom steel sawb?
Piv nrog rau lwm hom steel sawb, nws cov txiaj ntsig tseem ceeb nyob hauv nws qhov kev ua tau zoo tag nrho thiab cov nqi zoo heev -kev ua tau zoo. Piv nrog rau cov khaub thuas zoo tib yam- dov steel strip, zinc txheej imparts zoo heev corrosion kuj, tshem tawm qhov xav tau ntxiv los tiv thaiv- kho corrosion thiab txo cov nqi khiav hauj lwm tom qab. Piv rau kub-dip galvanized steel sawb nrog cov zinc coatings siab (xws li Z275), nws pheej yig dua, ua tau raws li cov kev xav tau ntawm cov cheeb tsam corrosive thiab tsim nyog rau cov nqi - cov haujlwm tseem ceeb. Piv nrog rau siab -lub zog alloy steel sawb, nws muaj superior txias sib sau thiab weldability, adapting rau ntau yam txheej txheem xws li dabtsi yog khoov, stamping, thiab vuam. Nws tuaj yeem ua tau raws li qhov kev xav tau ntawm kev ua haujlwm ntawm ntau yam kev lag luam, ua rau nws muaj ntau yam khoom siv uas sib npaug kev ua haujlwm, nqi, thiab kev ua haujlwm yooj yim.
Dab tsi yog qhov corrosion kuj ntawm DX51D + Z100 steel sawb?
Nws qhov kev tiv thaiv corrosion feem ntau yog nyob ntawm zinc txheej, uas tiv thaiv lub hauv paus steel sawb los ntawm kev tiv thaiv kev txi anode. Txawm hais tias zinc txheej hnyav ntawm Z100 yog nruab nrab- qis, nws tseem muab kev tiv thaiv corrosion zoo nyob rau hauv ib txwm muaj. Hauv qhov chaw qhuav hauv tsev, nws tuaj yeem nyob tau ntau xyoo. Sab nraum zoov, nyob rau hauv me me corrosive ib puag ncig (xws li nroog suburbs thiab cheeb tsam tsis muaj kuab paug), nrog rau kev tu, nws yuav kav ntev li 10-20 xyoo. Txawm li cas los xij, nyob rau hauv ib puag ncig corrosive hnyav (xws li thaj chaw ntug dej hiav txwv, thaj chaw muaj kev lag luam, thiab thaj chaw uas muaj cov av noo siab), zinc txheej depletes sai heev vim yog kev tawm tsam ntawm corrosive media xws li chloride ions thiab sulfides, uas ua rau muaj kev tiv thaiv corrosion tsawg. Yog li ntawd, ntxiv kev tiv thaiv corrosion (xws li tshuaj tsuag tshuaj tiv thaiv corrosion) yog tsim nyog.
DX51D + Z100 steel sawb puas tuaj yeem welded? Yog, nws tuaj yeem welded. Nws muaj qhov zoo tshaj plaws weldability thiab yog sib xws nrog ntau yam txheej txheem vuam, suav nrog arc vuam, tsis kam vuam, thiab roj tiv thaiv vuam. Thaum lub sij hawm vuam, zinc txheej melts ntawm qhov kub thiab txias, muaj peev xwm tsim zinc vapor. Kev tswj tsis raug ntawm vuam tsis tuaj yeem ua rau muaj qhov tsis xws luag xws li porosity thiab slag inclusions. Yog li ntawd, nws yog ib qho tseem ceeb los xaiv qhov tsim nyog vuam tam sim no, qhov hluav taws xob, thiab vuam ceev, thiab muab qhov cua txaus kom tsis txhob muaj teeb meem ntawm zinc vapor rau tib neeg lub cev. Rau cov welded pob qij txha uas yuav tsum tau ntau dua, zinc txheej nyob rau hauv lub weld cheeb tsam yuav raug tshem tawm ua ntej welding, thiab weld seam yuav tam sim ntawd kho nrog anti- kev kho corrosion tom qab vuam los xyuas kom meej corrosion kuj ntawm tag nrho cov qauv.
DX51D + Z100 steel sawb puas tuaj yeem stamped?:
DX51D yog ib qho txias- ua cov hlau nrog qee qhov℃ntawm formability, haum rau cov txheej txheem stamping yooj yim mus rau nruab nrab. Cov txheej txheem stamping yooj yim xws li kos duab ntiav, khoov, thiab blanking tuaj yeem ua tiav zoo yam tsis muaj kev tawg lossis tawg. Txawm li cas los xij, vim muaj kev txwv ntawm cov khoom muaj zog thiab elongation, ntau cov txheej txheem stamping nyuaj xws li kev sib sib zog nqus nqus thiab kev sib sau ua ke yuav ua rau muaj teeb meem kev ua haujlwm lossis txo cov khoom tawm los. Hauv cov xwm txheej no, nws raug nquahu kom xaiv qib DQ lossis siab dua steel sawb (xws li DX53D) kom ntseeg tau tias kev ua haujlwm zoo.
Lub neej kev pab cuam ntawm DX51D + Z100 steel sawb yog dab tsi?: Lub neej kev pab cuam cuam tshuam los ntawm ntau yam, nrog rau kev ua haujlwm ib puag ncig, kev ua haujlwm, thiab kev ntsuas kev saib xyuas, thiab txawv txav. Nyob rau hauv qhov chaw qhuav hauv tsev tsis muaj corrosive media, xws li cov khoom siv sab hauv ntawm cov khoom siv hauv tsev thiab cov khoom siv kho kom zoo nkauj sab hauv, lub neej kev pabcuam tuaj yeem ncav cuag 20-50 xyoo. Nyob rau hauv ib puag ncig sab nraum zoov zoo tib yam, xws li lub tsev ru tsev, qhov rooj thiab qhov rais, yog tias tsis muaj kev tiv thaiv ntxiv los tiv thaiv - kev tiv thaiv corrosion, lub neej kev pabcuam yog li 10-20 xyoo. Yog tias kev kho tshuaj tsuag tsis tu ncua, nws tuaj yeem txuas ntxiv mus rau 20-30 xyoo. Nyob rau hauv ib puag ncig corrosive heev xws li seaside cheeb tsam thiab chaw ua lag luam, yog siv ncaj qha, kev pab cuam lub neej tsuas yog 3-5 xyoo, thiab nws cov kev pab cuam lub neej yuav tsum tau txuas ntxiv los ntawm kev ntxiv cov tshuaj tiv thaiv corrosion thiab hloov tsis tu ncua.
