Kev txiav txim siab tseem ceeb rau kev ua haujlwm Stamped Khoov
Stamped khoov, tseem hu ua xovxwm khoov, yog ntau yam yeeb nkab fittings dav siv nyob rau hauv ntau yam lag luam vim lawv zoo heev corrosion kuj thiab oxidation kuj. Lawv feem ntau yog tsim los ntawm cov ntawv hlau nrog cov khoom sib xws ntawm cov kav dej thiab yog tsim los ntawm kev sib txuas ob lub voj voog khoov ua ke. Cov txheej txheem vuam rau stamped khoov yuav tsum ua raws li cov txheej txheem tshwj xeeb. Raws li cov txheej txheem vuam sib txawv siv rau ntau cov kav dej, cov khoom siv ua tiav feem ntau yog tsim los ntawm kev saib xyuas qhov taw tes rau qhov taw tes, nrog rau kev tsim kho ntawm qhov chaw ua raws li qib vuam ntawm cov kav dej, ua rau lub sij hawm "ob lub semi-stamped. khoov."
Cov ntsiab lus tseem ceeb los xav txog:
1. Corrosion thiab Oxidation Resistance:
Stamped khoov muaj zog tiv taus corrosion thiab oxidation, uas tau pab txhawb rau lawv cov kev siv dav hauv kev lag luam xws li tshuaj lom neeg engineering, chiv tsim, roj av, thiab kev tsim khoom siv kho mob.
2. Corrosion, Thaum tshav kub kub, thiab hnav tsis kam:
Stamped khoov muaj kev tiv thaiv corrosion tiv thaiv oxidative acids, organic acids, thiab cavitation. Lawv kuj yog kub-resistant thiab muaj zoo hnav tsis kam. Lawv pom cov ntawv thov hauv cov khoom siv thiab cov khoom siv hauv cov chaw tsim hluav taws xob, kev ua tshuaj lom neeg, thiab kev lag luam roj av.
3. Kev xaiv electrode:
Stamped khoov tuaj yeem coated nrog titanium-calcium lossis low-hydrogen electrodes. Thaum titanium-calcium electrodes tuaj yeem siv rau ob qho tib si alternating tam sim no (AC) thiab ncaj qha tam sim no (DC) vuam, AC vuam ua rau muaj kev nkag mus rau hauv ntiav thiab muaj feem ntau dua ntawm cov cua sov. Yog li, nws raug nquahu kom siv cov khoom siv hluav taws xob DC thaum twg los tau thaum vuam stainless hlau stamped khoov.
4. High Hardness thiab Post-Weld Cracking:
Stamped khoov muaj qib siab hardness thiab muaj feem xyuam rau tom qab vuam tawg. Txhawm rau ua kom cov welds zoo, nws yog ib qho tseem ceeb uas yuav tau xaiv cov vuam vuam uas tsim nyog. Thaum vuam stainless hlau stamped khoov ntawm tib hom, tom qab vuam cua sov yuav tsum tau kho. Qhov no suav nrog preheating rau qhov kub siab tshaj 300 degree thiab maj mam txias kom kub qis dua 700 degree. Yog tias cov khoom siv welded tsis tuaj yeem raug kho tom qab vuam kub, chromium-nickel stamped khoov yuav tsum raug xaiv. Ntau hom electrodes muaj cov yam ntxwv ntawm kev ua tau zoo, thiab lawv cov kev xaiv yog raws li cov kev cai tshwj xeeb los xyuas kom meej qhov zoo ntawm cov welded stamped khoov.
5. Alloying Elements for Enhanced Properties:
Txhawm rau txhim kho corrosion kuj thiab weldability, me me ntawm stabilizing ntsiab xws li titanium, niobium, thiab molybdenum feem ntau yog ntxiv thaum lub sij hawm tsim khoom. Qhov no ua rau zoo weldability piv rau chrome stamped khoov. Thaum siv tib hom chrome stainless hlau stamped khoov, qhov kub thiab txias ntawm qhov tsawg kawg yog 200 degree yog tsim nyog, ua raws li 800 degree annealing txheej txheem tom qab vuam. Nyob rau hauv rooj plaub uas cov welded tivthaiv tsis tuaj yeem kho cua sov, chrome-nickel stainless hlau stamped khoov yuav tsum tau xaiv.
Nyob rau hauv cov ntsiab lus, stamped khoov yog khoom plig rau lawv corrosion kuj thiab versatility nyob rau hauv ntau yam kev siv. Txhawm rau ua tiav cov vuam zoo, xaiv cov khoom siv hluav taws xob zoo, ua cov kev kho cua sov kom tsim nyog, thiab xav txog cov kev cai tshwj xeeb ntawm daim ntawv thov yog cov kauj ruam tseem ceeb hauv kev tsim khoom thiab siv cov khoom siv khoov. Cov kev txiav txim siab no ua kom lub neej ntev thiab kev ua haujlwm ntawm stamped khoov hauv kev lag luam sib txawv.
