Nov yog ntau yam khoom rau koj xaiv los ntawm
1. Vim li cas thiaj muaj flange tawg tom qab vuam
Hauv kev tsim cov khoom ntim khoom, thaum lub stainless hlau flange thiab lub tog raj kheej yog welded, yuav muaj kab nrib pleb nyob rau hauv lub caj dab ntawm flange, tsis nyob rau hauv vuam seam.Dab tsi yog qhov teeb meem?Vim li cas thiaj muaj qhov xwm txheej zoo li no?Ua ntej ntawm tag nrho cov, cia peb txheeb xyuas cov laj thawj ntawm qhov kub tawg.
Cov kab nrib pleb kub yog cov kab nrib pleb tsim nyob rau hauv qhov kub siab thaum lub sij hawm txias txheej txheem ntawm vuam, feem ntau yog nyob rau hauv cov hlau weld, thiab ib tug me me nyob rau hauv qhov ze seam cheeb tsam.Nws tuaj yeem muab faib ua crystallization (solidification) tawg, liquefaction tawg thiab polygonal tawg.Crystalline tawg yog hom ntau tshaj plaws, feem ntau nyob rau hauv welds ntawm carbon steels muaj ntau impurity ntsiab (S, P, Si thiab C), ib-theem austenitic stainless hlau, txhuas thiab nws alloys thiab lwm yam welded lug.Lub ntsiab tseem ceeb cuam tshuam yog vuam tensile kev nyuaj siab, qis melting point eutectic (tshuaj muaj pes tsawg leeg ntawm cov hlau weld), lub degree ntawm overheating ntawm lub welded ob leeg (txheej txheem).
2.Yuav ua li cas kom tsis txhob kub tawg
Judging los ntawm cov duab, 304 stainless hlau muaj zog plasticity.Yog tias nws yog forged flange, cov txheej txheem vuam yuav tsum tau xoob, thiab cov kab nrib pleb feem ntau tsis tshwm sim.Yog tias nws yog ib qho casting, qhov xwm txheej no yuav tshwm sim.Yog li, hauv kev xyaum, peb yuav ua li cas kom tsis txhob tawg ntawm qhov chaw ua haujlwm?Kev ntsuas los txo qhov nyiam ntawm kub tawg muaj xws li:
1) Txo cov ntsiab lus ntawm impurity ntsiab xws li S thiab P hauv cov khoom.
2) Kev ua kom zoo ntawm Mn / S piv tuaj yeem hloov Fe ntawm Fe-FeS qis-melting eutectic los ua MnS nrog lub melting point ntawm 1620Co, yog li txhim kho qhov tawg tsis kam ntawm vuam.
WC = 0.10 ~ 0.12%, WMn = 2.5% ua ntej nws ua haujlwm
WC = 0.13 ~ 0.20%, WMn = 1.8% los yog tsawg dua
WC = 0.21 ~ 0.23%, qhov muaj txiaj ntsig zoo ntawm WMn yog nqaim.
3) Siv cov txheej txheem vuam tsim nyog thiab cov txheej txheem los tswj cov kab hluav taws xob tawm tswv yim thiab txo cov vuam overheating.
4) Ntxiv Ti, Mo, Nb lossis tsis tshua muaj ntiaj teb cov ntsiab lus rau cov khoom siv vuam los tiv thaiv kev txhim kho ntawm cov nplej nplej, kho cov nplej, thiab txhim kho kev ua tau zoo.
