Kev Siv Tshuab Ntawm Super Duplex Stainless Hlau Welded Yeeb Nkab

Kev Siv Tshuab Ntawm Super Duplex Stainless Hlau Welded Yeeb Nkab

Date:Jan 10, 2019

Txawm li cas los xij, super duplex steel yog nkag siab rau theem peb nag lossis daus, xws li cov kev sib txuas intermetallic, thiab yuav ua li cas los tswj cov txheej txheem hauv vuam thiab kev kho cua sov yog qhov teeb meem nyuaj hauv kev tsim cov khoom no.


Paub tab Super Duplex Steel S32750 welded yeeb nkab tsim cov txheej txheem yog:


1, cov txheej txheem tshwj xeeb: cov khoom siv tshuaj xyuas-steel phaj ultrasonic qhov khuam pom pom-planer ntug-molding-pre-vuam - tag nrho lub voj voos-txiav-vuam-taag txoj kab uas hla + kub kho-yeeb nkab kawg ntxiv-weld txoj kev kuaj-yeeb nkab qhov kawg mus kuaj-hydraulic kuaj-pickling passivation-tiav cov khoom tshuaj ntsuam xyuas Cim Ntim chaw tus neeg.


2, moulding hauv kev lag luam ntawm ncaj ncaj seam welded yeeb nkab, qhov nyuaj ntau lawm nyob rau hauv txoj kev siv tau zoo ntawm khoov lub caij rau ntug ntawm cov hlau siv, kev siv cov tshuaj molding tshuab yog qhov nyuaj los daws, thiab duplex stainless hlau tawm los muaj zog ntawm txog ob zaug lub sij hawm dog dig austenitic stainless hlau, nws molding yog qhov nyuaj ntau. FFX (Flexible moulding) raws li cov tshuab moulding tshiab siv ntse siv cov nro cov nyhuv thaum lub kauj yog khoov rau ntau qhov khoov thaum kawg rau ntawm ntug ntawm cov hlau nqaj hlau, thiab los ntawm kev siv cov kev ua haujlwm zoo ntawm yob infinity, moulding degree ntawm khoov ntug yuav tuaj yeem hloov kho raws li qhov muaj zog thiab tuab ntawm txoj hlua khi steel kom thiaj li ua tiav cov vuam zoo.


3, vuam rau qhov kev siv ntawm lub tshuab ntshav arc vuam (PAW) thiab tungsten Argon arc vuam (GIAW) txheej txheem vuam kev. Ua ntej tshaj plaws, kev siv ntshav ntawm arc vuam nkag mus rau fusion, thiaj li ua tiav ntawm cov vuam ib leeg, ob npaug moulding nyhuv, tom qab siv Tungsten argon arc vuam rau kev sau thiab npog, vuam siv kev tiv thaiv ntshiab argon. Txhawm rau txo qhov nyiam ntawm cov teeb meem theem nag lossis daus, cov txheej txheem welding kom deb li deb tau los siv qis kab hluav taws xob, kab lub zog zoo tshaj tsis tshaj 16kj / cm. Tsis tas li, txheej txheej nug qhov kub thiab txias yog qhov tseem ceeb heev rau lub vuam ntawm duplex steel, yuav tsum tswj tau qis dua 100 ℃, qhov kub tsis sib xyaw ua haujlwm siab yuav ua rau muaj qhov cuam tshuam ntawm cov teeb meem theem nag lossis daus, thiab thaum kawg cuam tshuam rau cov khoom lag luam.


4, kev kho cua sov tom qab vuam kev kho cua sov siv cov induction rauv kom tag nrho cov yeeb nkab cov khoom siv tshuaj, kev kho cua sov txog 1050-1120 ℃, dej txau txias kom txog 40 ℃ hauv qab no.
