Lub ci ci annealed stainless hlau raj tuaj yeem siv dav hauv kev sib pauv cua sov, boilers, txias, thiab cua sov.
1. Lub ntsiab lus ntawm kev ci ntsa iab
Ci annaling (BA) yog hais txog cov khoom siv steel hlau nyob rau hauv ib qho cua sov, thiab tom qab ntawd cov khoom siv hluav taws xob txo qis, thiab tom qab ntawd cov khoom siv hluav taws xob kom zoo dua, Cov txheej tiv thaiv tuaj yeem tiv thaiv corrosion thiab yaig.
Feem ntau hais lus, saum npoo ntawm cov yeeb nkab steel yog smoother thiab ci dua. Feem ntau, cov txheej txheem no tau pom los ntawm ib leeg-raj hauv online ci analing khoom siv. Kev siv ua rauv muffle rauv tsis yog yuav tsum tau ua preheated, uas ua rau kev siv zog loj; Nws tseem muaj cov huab cua tsis zoo, uas ua rau cov yeeb nkab kom ua dub tom qab annealing thiab xav tau pickled.
Hangao Machinery) Tech ( Lubricees Ntse-Txuag Online Ntsig Intruction Cov Khoom Siv Analealing Seko Ntxiv mus, vim tus qauv tsim nyog, tsis tas yuav siv cov dej nyab, thiab tus nqi txaus yog me me, tsuas yog ob peb liv ib feeb. Thiab muaj cov tshuaj tiv thaiv kev tso pa tawm thiab hlawv kom tiv thaiv hydrogen los ntawm kis mus rau ib puag ncig ib puag ncig thiab cov xwm txheej txaus ntshai.
Nyob rau hauv tus txheej txheem ntawm kev ci ntsa iab, qee yam tseem ceeb heev rau qhov zoo ntawm cov yeeb nkab steel. Yog hais tias tus txheej txheem ci ci ci tsis raug, nws yuav ua rau tawg thiab tejzaum nws corrosion. Lub raj xaav tau yooj yim feem ntau nyob rau hauv lub xeev ci ci ntsa iab.
2. Ua ntej ci annealing
Cov yeeb nkab ntawm cov yeeb nkab yuav tsum huv huv, thiab yuav tsum tsis muaj lwm tus neeg txawv teb chaws lossis av. Txhua yam sab laug nyob rau saum npoo ntawm cov yeeb nkab yuav ua kev puas tsuaj rau saum npoo ntawm cov yeeb nkab thaum ua.
3. Ntxiv cov roj hauv roj
Lub annealing cua yuav tsum yog cov pa-dawb, cais cov khoom, thiab ua ib lub tshuab nqus tsev. Ntxig roj nkig, hydrogen lossis argon, kom tau txais cov nyhuv ci.
4. Annealing kub
Kev siv tshuab kub ib qho yuav tsum tau txiav txim siab raws li cov qib sib txawv ntawm cov qauv stainless hlau. Feem ntau, lub annealing kub ntawm Austenitic steel yog tsawg kawg yog 1040 degrees, thiab lub sijhawm siv tsis tseem ceeb. Lub siab dua yog tsim nyog yuav muaj lub zog ci ntsa iab. Cov cua kub yuav tsum tau sai li sai tau, cov cua sov qeeb yuav ua rau oxidation.
Qee cov hlau ferritic stainless yuav tsum muaj kev kub siab qis dua, xws li TP439, uas tsis tuaj yeem ua rau muaj kev sib tw ci ci, thiab dej quenching yuav ua rau kev tsim cov tshuaj oxide.
Tom qab cov annead ci, nkag mus rau theem kawg ntawm sizing thiab ncaj. Qhov saum npoo ntawm stainless hlau raj nthuav qhia cov teeb ci ci, thiab lub raj ci ci ci tsis tas yuav pickled.
5. Lub hom phiaj thiab qhov zoo ntawm kev ci ntsa iab
(1) Tshem tawm cov khoom ua haujlwm hnyav thiab tau txais kev zoo ntawm daim hlau sib dhos;
(2) Tau txais lub ci ci, tsis-oxidized, thiab corrosion-resistant nto;
(3) Kev kho kom zoo ua rau lub ntsej muag yob du, thiab lub ci ci ci tuaj yeem tau txais yam tsis muaj kev kho tom qab.
