Kauv Welded Yeeb Nkab rau Cov Hluav Taws Xob Hluav Taws Xob hauv av EN10219
Pebkauv welded kavyog qhov kev daws teeb meem zoo tshaj plaws rau cov haujlwm uas muaj kev tiv thaiv corrosion thiab kev ua haujlwm ruaj khov yog qhov tseem ceeb. Cov txheej txheem welding tshwj xeeb tsis yog tsuas yog txhim kho lub zog ntawm cov yeeb nkab, tab sis kuj muab cov seamless nto, txo qhov kev pheej hmoo ntawm kev xau thiab kev ua tsis tiav. Qhov no ua rau lawv tshwj xeeb tshaj yog haum rau qhov hnyav ib puag ncig feem ntau ntsib hauv cov ntawv thov hauv av.
Tus qauv EN10219 ua kom peb cov kav dej tau tsim nrog qhov tseeb thiab zoo, kom ntseeg tau tias lawv tuaj yeem tiv taus cov kev kub ntxhov thiab cov teeb meem ntawm kev thauj mus los ntawm cov roj av. Tsom ntsoov rau kev ua haujlwm ntev thiab kev cia siab, peb cov kav dej welded yog tsim los muab kev ua haujlwm ntev, txo qhov kev xav tau ntawm kev tu thiab hloov ntau zaus.

a. Txoj kev deoxidation yog tsim raws li hauv qab no:FF: Tag nrho cov hlau uas muaj nitrogen khi cov ntsiab lus hauv cov nyiaj txaus los khi muaj nitrogen (xws li min. 0,020% tag nrho Al lossis 0,015% soluble Al). b. Tus nqi siab tshaj plaws rau nitrogen tsis siv yog tias cov tshuaj muaj pes tsawg leeg pom qhov tsawg kawg nkaus Al ntsiab lus ntawm 0,020% nrog qhov tsawg kawg nkaus Al / N piv ntawm 2: 1, lossis yog tias muaj lwm yam N-binding ntsiab. Cov ntsiab lus N-binding yuav tsum tau sau rau hauv Cov Ntaub Ntawv Tshawb Fawb. |
Ntxiv nrog rau lawv cov kev tsim kho rugged, cov kav dej no yog lub teeb yuag thiab yooj yim rau kev ua haujlwm, ua rau kev teeb tsa tau zoo dua thiab raug nqi. Txawm hais tias koj tab tom ua ib txoj haujlwm tshiab los yog kho dua tshiab rau qhov uas twb muaj lawm, peb cov kav dej welded muab kev sib xyaw ua ke zoo tshaj plaws ntawm lub zog, hloov tau, thiab ua raws li cov qauv kev lag luam.
Xaiv peb cov kav welded kauv rau koj cov kav dej hauv av xav tau thiab muaj kev thaj yeeb nyab xeeb ntawm lub siab uas los nrog kev siv cov khoom sib ntsibTS EN 10219qauv. Cia siab rau peb txoj kev cog lus rau kev ua tau zoo thiab kev ua tau zoo los xyuas kom muaj kev nyab xeeb thiab kev ua haujlwm ntawm koj cov khoom siv roj av.
