Cov khoom lag luam
Peb lub chav hlau Duplex cheat ua raws li Astm A240 / A240 / A240M cov qauv, nrog rau cov microstructure uas yog kwv yees 50% austenite 50% ferrite. Qhov kev sib npaug no muab nws ob qho tib si loj zog thiab txoj kev ua kom muaj zog tshaj plaws (pren
Nyob rau hauv cov dej hiav txwv ntxuav dej Nws yog ib qho khoom lag luam xaiv roj thiab roj pipelines, tshuaj xyuas cov nroj tsuag, thiab offshore cov qauv uas nyob rau qhov twg ruaj khov feem ntau.
Kev Ua Hoobkas
Hais txog kev kho deg, peb tuaj yeem ua tau ib qho thiab passivation. Qhov saum npoo tom qab pickling tag nrho ua raws li cov astm A380 tus qauv, nrog lub ro roughness ra hauv qab no 1.6μm, thiab cov nplai thiab oxide yog kho kom huv. Kev Kho Mob Passivation yuav tsim 4-63M tiv thaiv zaj duab xis - Qhov no tau sim los ntawm x-tshav zaub fluorescence, uas tuaj yeem nce cov xeb tsis kam los ntawm 35%.
Peb tseem nruj tswj cov kev pabcuam slitting thiab tej kev txiav txim siab: Qhov yuam kev dav yog tswj tau nyob rau hauv ± 0.15mm, thiab txoj kev ncaj ntawm cov hlau coil ib zaug tsawg dua 1 hli. Nyob rau hauv txoj kev no, thaum cov neeg yuav rov qab los ua nws rau hauv cov khoom tiav, yuav muaj khib nyiab ntau thiab nws yuav yooj yim dua.
Ntau lawm lub zog
Peb khiav 3 tshwj xeeb chav hlau ntau lawm, siv cov thev naus laus zis ntau lawm, ua kom cov ntsiab lus hydrogen hauv qab 3ppm-qhov no nres cov kab mob hydrogen-induced tawg. Peb lub lab lab siv kho qhov muag kho qhov muag (qhov tseeb 0.001%) txhawm rau txheeb xyuas txhua tus kab ke, thiab peb ua haujlwm cuam tshuam ntawm -40 Qib (ib astm E23) kom paub meej.
Nrog rau txhua xyoo cov txiaj ntsig ntawm 30000 tons, peb nyob nraum ib qho ntawm ob peb lub chaw ua haujlwm hauv Tebchaws Europe thiab Asia uas tuaj yeem tsim cov Duplex Steel kauj nrog ruaj khov ferrite-Austenite ratios. Peb khaws 1000 tons hauv Tshuag, npog 0.5-6mm thicknesses.
Hoobkas cog lus cog lus
Kev txiav txim tshaj 30 tons tau txais 6% qhov ntim luv nqi thiab kev kho kom dawb. Peb lav tau tias yog tias muaj coil tsis ua raws li A240 tus qauv lossis qhia pitting tsis pub dhau 3 xyoos, peb yuav hloov nws nyob rau hauv tag nrho cov kev puas tsuaj los ntawm kev qeeb.
