Peb Cov Txheej Txheem Tseem Ceeb ntawm A213 Stainless Hlau Welded Pipes

• Cold Rolling thiab Annealing

Txias Rolling: Cov txheej txheem no suav nrog kev siab thiab tensile deformation. Thaum smelting tuaj yeem hloov kho cov tshuaj muaj pes tsawg leeg ntawm cov ntaub ntawv steel, txias dov tsis hloov cov tshuaj muaj pes tsawg leeg ntawm A213 steel. Hloov chaw, nws cuam tshuam txog kev hla lub kauj los ntawm cov chais ntawm cov khoom siv txias dov nyob rau hauv ntau yam kev ntxhov siab kom txo nws cov tuab. Qhov kawg precision dov kauj ruam ua kom lub coil lub thickness raug, feem ntau nyob rau hauv 0.03 hli.

Annealing: Tom qab txias dov, lub kauj yog muab tso rau hauv ib qho tshwj xeeb annealing rauv thiab rhuab mus rau ib tug tshwj xeeb kub (900-1100 degrees Celsius). Qhov ceev ntawm lub qhov cub annealing yog kho kom ua tiav qhov xav tau hardness. Rau cov khoom siv softer, lub annealing ceev yog qeeb, uas ua rau tus nqi nce. Ob leeg 201 thiab 304 yog austenitic stainless hlau thiab yuav tsum tau ceev cua sov thiab txias thaum lub sij hawm annealing kom zoo rov qab metallurgical qauv puas los ntawm txias dov. Yog li ntawd, annealing yog ib kauj ruam tseem ceeb. Tsis zoo annealing tuaj yeem ua rau muaj teeb meem xeb.

Cov txheej txheem kev kho cua sov hlau yuav ua rau cua sov lub workpiece mus rau qhov kub thiab txias, tswj nws ntawm qhov kub thiab txias rau ib lub sijhawm, thiab tom qab ntawd maj mam txias nws. Lub hom phiaj ntawm annealing yog:

1. Txhawm rau txhim kho lossis tshem tawm ntau yam teeb meem ntawm cov txheej txheem thiab cov kev ntxhov siab uas tshwm sim thaum lub sij hawm casting, forging, dov, thiab vuam txheej txheem, yog li tiv thaiv deformation thiab tawg ntawm lub workpiece.
2. Ua kom soften lub workpiece kom yooj yim machining.
3. Txhawm rau txhim kho cov qauv ntawm cov nplej thiab txhim kho microstructure, yog li txhim kho cov khoom siv kho tshuab ntawm cov khoom ua haujlwm thiab npaj cov khoom siv rau kev kho cua sov zaum kawg thiab kev tsim cov yeeb nkab.

• Slitting

Slitting suav nrog txiav stainless hlau coils rau hauv ib daim hlab ntawm qhov xav tau dav rau kev ua haujlwm ntxiv thiab kev tsim cov yeeb nkab. Thaum lub sij hawm slitting txheej txheem, nws yog ib qho tseem ceeb los xyuas kom meej kev tiv thaiv kom tsis txhob khawb cov coils. Kev saib xyuas yuav tsum tau them rau qhov dav thiab qhov tseeb ntawm cov slits, nrog rau kev tiv thaiv burrs thiab cov npoo ntse, uas tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov yeeb nkab tsim cov txheej txheem. Kev ua tsis zoo slitting tuaj yeem ua rau muaj qhov tsis xws luag hauv cov kav dej welded, ncaj qha cuam tshuam cov txiaj ntsig ntawm cov khoom kawg.

• Polishing

Tom qab cov yeeb nkab A213 raug tsim, nws dhau los ua polishing siv lub tshuab polishing. Kev kho saum npoo ntawm cov qauv thiab cov kav dej zoo nkauj feem ntau suav nrog ntau cov txheej txheem, suav nrog polishing, uas tuaj yeem muab faib ua ci ntsa iab (daim iav), 6K, thiab 8K tiav kom tau raws li ntau tus neeg siv khoom.

Raws li kev paub txog steel yeeb nkab xa khoom, GNEE Group muab hwm A213 stainless hlau welded kav rau txhua tus neeg siv khoom. Thov hu rau peb yog tias koj xav tau peb cov khoom.
