Tam sim no, kev kho cov roj flue hauv Suav teb feem ntau yog ntub dej desulfurization. Cov roj flue uas tsim los ntawm txoj kev no yog corrosive ntau dua li lwm cov txheej txheem, thiab kev ua haujlwm ntawm cov pob zeb chimneys maj mam ua tsis tau raws li qhov xav tau ntawm cov txheej txheem desulfurization tam sim no. Lub chimneys hauv tsev tau maj mam mus txog lub neej tsim, thiab ntau thiab ntau lub chimneys tab tom ntsib kev rhuav tshem lossis kho dua tshiab. Lub built-intitanium steel composite phajchimney tuaj yeem cais cov pob zeb ua lub tog raj kheej los ntawm cov roj flue, uas tuaj yeem txo qis tus nqi corrosion thiab ua kom ntev lub sijhawm corrosion. Lub vuam seam ntawm titanium nto yog qhov tsis muaj zog txuas rau corrosion kuj ntawm titanium nto. Qhov vuam zoo ncaj qha cuam tshuam rau kev pab cuam lub neej ntawm cov khoom, yog li nws yog ib qho tseem ceeb tshwj xeeb los xyuas kom meej qhov vuam zoo ntawm titanium nto.
1. Lub hauv paus ntsiab lus ntawm cov txheej txheem vuam
(1) Lub zog tag nrho ntawm titanium-steel composite chimney yog los ntawm cov pa roj carbon steel, thiab titanium txheej tsuas yog ua lub luag haujlwm ntawm kev sib khi thiab tiv thaiv corrosion. Qhov vuam ntawmtitanium steel clad phajcladding (titanium steel) txais argon arc vuam. Txhawm rau kom ntseeg tau tias titanium txheej tsis oxidized los ntawm tshav kub thaum cov pa roj carbon steel ib feem ntawm lub substrate yog welded, titanium txheej nyob ib ncig ntawm lub substrate welding yog trimmed, thiab ib tug titanium sawb yog txuas rau vuam thiab sealing.
(2) Titanium tuaj yeem nqus tau hydrogen sai sai thaum qhov kub siab tshaj 300 degree, oxygen tuaj yeem nqus tau sai thaum nws siab tshaj 450 degree, thiab nitrogen tuaj yeem nqus sai sai thaum nws siab tshaj 600 degree, uas yog, "oxidation". Thaum cov pa phem no nkag mus rau hauv titanium, lub plasticity thiab toughness ntawm cov welded sib koom yuav hloov pauv loj, tshwj xeeb tshaj yog saum 882 degree, cov nplej ntawm cov pob qij txha yog coarsened, thiab cov qauv martensite yog tsim thaum lub sij hawm txias, uas ua rau kev sib koom ua ke muaj zog, hardness, thiab hardness. Lub plasticity thiab toughness txo, lub siab nyiam overheat yog hnyav, thiab kev sib koom tes yog nkig heev. Yog li ntawd, qhov kub thiab txias ntawm titanium yuav tsum nruj me ntsis tswj nyob rau hauv 300 degree thaum lub sij hawm tsim ntawm cov txheej txheem tsis thiab vuam txheej txheem.
2. Welding zoo tswj ntsuas
1) Tom qab titanium steel-clad phaj nkag mus rau hauv qhov chaw, nws yog ib qho tsim nyog los tiv thaiv cov khoom tiav kom tsis txhob muaj kab mob thiab kev puas tsuaj rau titanium nto. Thaum lub titanium-steel composite phaj yog dov, lub yob yuav muaj kev sib cuag ncaj qha nrog titanium nto, thiab qhwv cov yas zaj duab xis ntawm yob tuaj yeem tiv thaiv titanium nto.
2) Cov pa steel phaj clamps muaj cov hniav ntawm ib sab thiab cov thawj coj ntawm lwm qhov. Sib tsoo sab ntawm tus thawj tiaj tus thiab welded ib daim hlau nyias. Thaum lub titanium composite phaj yog hoisted, sab hniav yog nyob rau hauv kev sib cuag nrog cov pa roj carbon steel txheej, thiab cov tshiab nyias hlau phaj tsub kom qhov kev sib cuag nto ntawm lub phaj clip thiab titanium txheej, txo lub siab ntawm titanium txheej, thiab xyuas kom meej tias. titanium txheej tsis puas.
3) Lub deformation ntawm coil phaj thaum lub sij hawm thauj mus los yuav ua rau kom cov kev kho ntawm lub teeb-up. titanium txheej yog nyob rau sab hauv ntawm lub chimney steel, thiab nws yuav inevitably cuam tshuam rau titanium nto thaum lub sij hawm kho. Txo kev thauj mus los deformation tuaj yeem txo qhov kev ua haujlwm ntawm kev kho, yog li txo qhov cuam tshuam ntawm titanium nto. Ua ib lub tsheb thauj neeg tshwj xeeb, thiab siv lub forklift rau lub nkoj luv luv kom txo tau qhov deformation ntawm lub kauj.
4) Ua ntej vuam, nws yuav tsum tau ua tib zoo tshem tawm cov oxides, nitrides, roj stains, noo noo, thiab lwm yam organic pollutants nyob rau saum npoo ntawm vuam thiab vuam hlau.
5) Thaum lub sij hawm kub dov txheej txheem ntawm titanium-steel clad phaj, titanium nto yog coated nrog ib tug tso tawm neeg sawv cev, thiab tus neeg sawv cev tso tawm yog kho nyob rau saum npoo ntawm titanium txheej tom qab cov khoom tiav. Tom qab qhov kev xeem welding, weld seam yog oxidized thiab discolored tiag. Txhawm rau tshem tawm cov khoom tso tawm ntawm cov titanium nto ze ntawm qhov vuam, los ntawm kev sim, kev sib tsoo, tshuaj ntxuav nrog carbon tetrachloride, txiv tsawb dej, thiab lwm yam tshuaj ntxuav tsis tuaj yeem tshem tawm cov kua dej tawm. Thiab lwm yam kev siv tshuab, cov txiaj ntsig tau pom tau tias kev txhaj tshuaj peening tuaj yeem tshem tawm cov titanium nto curing tso tawm tus neeg sawv cev.
3. Vuam ib puag ncig
Thaum lub sij hawm CO2 gas-shielded vuam thiab argon arc vuam, cua ceev yuav tsum tsis pub tshaj 2m / s. Yuav tsum tau ntsuas cua thiab nag los tiv thaiv rau qhov chaw vuam. Txij li cov hlau sab hauv yog tsim nyob rau hauv lub pob zeb chimney, sab saum toj ntawm lub chimney thiab qis manhole qhov rooj yuav tsum tau ntsia. Kaw, uas tuaj yeem ua kom ntseeg tau qhov kev xav tau ntawm ib puag ncig vuam.
