Cov txiav kev ntawm duplex stainless hlau

Date:Jun 21, 2019

Cov txheej txheem feem ntau siv rau austenitic stainless hlau thiab cov pa roj carbon hlau tuaj yeem siv rau duplex stainless hlau txiav, tab sis qee qhov kev hloov kho rau cov tsis xws li tsim nyog kom haum rau cov khoom kho tshuab thiab cov khoom cua sov.

1. Sawv

Duplex stainless hlau yog qhov nyuaj dua kom pom dua cov pa roj carbon hlau vim nws lub zog loj, kev ua haujlwm siab lub zog thiab tsis muaj kev suav nrog uas ua rau ua cov nti tawg. Kev siv lub tshuab ua kom muaj zog, muaj zog pom cov tshuab ncaj, tshuab ntxhua pom lub ntsej muag, qeeb-rau-nruab nrab ceev txiav nrawm, muaj cov khoom hnyav, thiab txaus coolant txaus (nyiam dua ib qho kev sib xyaw ntawm lubrication thiab cua txias) Cov emulsifier tso cai pom cov hniav hloov pauv coolant rau lub workpiece, thiab lwm yam, kom muab cov txiaj ntsig zoo tshaj plaws. Qhov txiav txiav ceev thiab pub tus nqi yuav tsum zoo ib yam li 316 austenitic stainless hlau.

2. Txiav

Lub duplex stainless hlau txiav rau cov cuab yeej siv tib yam li 304 thiab 316 stainless hlau, thiab feem ntau tsis tas yuav muaj kev kho kom haum tshwj xeeb. Txawm li cas los xij, vim lub siab shear lub zog ntawm duplex stainless hlau, nws yog qhov tsim nyog yuav tsum tau nce lub zog shear lossis txo shear tuab.

Rau cov ntawv kub dov thiab txias dov ua cov ntaub npauj, qhov shear zog ntawm stainless hlau yog kwv yees li 58% ntawm lub zog tensile. Raws li qhov muaj tiag tiag cov plaub txiab dag piv, duplex stainless hlau coj zoo li thicker 316 stainless hlau. Yog li ntawd, nyob rau hauv ib qho tshwj xeeb shear, lub siab tuab ntawm 2304 thiab 2205 duplex stainless hlau tuaj yeem raug txiav txog 75% ntawm cov tuab ntawm 304 thiab 316 stainless hlau, thaum lub siab tshaj plaws tuab uas super duplex stainless hlau tuaj yeem raug sheared yog dog dig austenitic 65 % ntawm lub cev stainless hlau.

austenitic stainless steels and carbon steels can be used for duplex stainless steel cutting

3. Muag daj

Pa ya hlau chev slitters tuaj yeem siv los txiav duplex stainless hlau coil thiab kab txaij. Lub duplex stainless hlau kauj tau pub los ntawm uncoiler thiab dhau los ntawm kev sib tsoo xov lub ntsej muag ntawm cov cuab yeej qis dua ntawm cov kab sib chaws, thiab coj rov qab rewinds lub sheared steel kauj. Txoj hauj lwm ntawm lub dab hniav tuaj yeem hloov kho kom haum raws li qhov xav tau qhov sib txawv ntawm cov coil. Txij li lub zog ntawm duplex stainless hlau yog siab dua li ntawm austenitic stainless hlau, hnav cov cuab yeej slitting thiab ruaj khov ntawm ntug yog qhov nyuaj los tswj. Ua kom tau txais cov txiaj ntsig ntev ntev kom zoo ntawm duplex stainless hlau kauj yuav tsum tau siv cov cuab yeej steel los yog carbide inserts.

4. xuas nrig ntaus

Ntaus nrig tuaj yeem pom raws li qhov nyuaj ntawm kev txiav plaub hau. Lub zog siab, kev ua haujlwm ceev nrawm thiab tsim kua muag tsis kam ua rau duplex stainless hlau kuj nyuaj rau punch thiab hnav lub cuab yeej. Lub ntsiab lus nkag kom zoo dua thiab cov hauv paus ntsiab lus yog kho cov duplex stainless hlau raws li ob chav-tuab austenitic stainless hlau. Punching ntawm high alloyed duplex stainless hlau nrog ntau dua nitrogen cov ntsiab lus yog qhov nyuaj dua.

5. Ntshav thiab laser txiav

Duplex stainless steels feem ntau ua tiav siv tib lub plasma txiav thiab laser txiav khoom siv li austenitic stainless hlau. Lub siab dua thermal conductivity thiab cov ntsiab lus sulfur tsawg ntawm duplex stainless hlau yuav muaj qhov cuam tshuam me ntsis ntawm qhov tsis zoo, tab sis zoo siab tuaj yeem tau txais tsis muaj kev kho tshwj xeeb. Lub tshav kub cuam tshuam cheeb tsam (HAZ) ntawm lub plasma txiav cov txheej txheem feem ntau nqaim, kwv yees 0.25 hli (0.010 nti), vim hais tias kev txiav yog ib qho hla, kev ua haujlwm ceev, thiab daim ntawv txias sai. Kev ua haujlwm ntawm lub weld bevel thiab cov nplawm ntawm cov hlau nyob ze lub hauv paus hlau thaum lub sijhawm vuam cov txheej txheem tshem tawm cov cua sov cheeb tsam ntawm lub qhov ntshav ntuag. s sib txawv.
