304 304L 316 316L Hlau Stainless Tubes Kev Xa Cov Tub Rog

Date:Dec 20, 2018

Thaum cov qhua tuaj noj mov ua cov kav hlau xaj hlau, kev xa khoom xa tuaj yuav tsum tau qhia hauv daim ntawv cog lus.


Cov xwm txheej tsis muaj stainless hlau xa tawm muaj xws li kub ntxuag, txias dov, tswj yob, ib txwm ua haujlwm, npau taws, annealing, quenching, tig mus, thiab lwm yam, lub xeev yob kub yob muaj txiaj ntsig txo kev siv zog, txo tus nqi, tuaj yeem ua kom zoo dua kev ua haujlwm ntawm stainless hlau tub thiab alloys. Cov.


Kev sib tsoo txias yog kev siv kub-dov ua cov hlau tsis txias zoo li cov khoom siv los ntawm cov khoom siv raw, tom qab pickling kom tshem tawm cov tawv nqaij oxide kom txias txias tas li dov, cov khoom tiav yog dov nyuaj lub kauj, vim tias qhov kev nruam txias txias los ntawm txias tawv tawv thiaj li tias lub zog ntawm dov nyuaj kauj, hardness sawv, toughening Performance index poob, yog li nws cov kev ua tau zoo yuav zuj zus, tsuas yog siv los tsim cov qauv yooj yim


Cov yob tswj kev sib tsoo yog txoj kev tswj kev dov, uas yog, ntawm kev kho cov tshuaj lom neeg lub cev ntawm cov yeeb nkab steel hlau, los ntawm kev tswj cov cua kub, dov kub, deformation system thiab lwm qhov kev siv thev naus laus zis, tswj kev hloov txoj cai ntawm austenitic stainless hlau cov ntaub so ntswg thiab lub microstructure ntawm cov khoom hloov theem, kom ua tiav ntawm Kev Koom Tes Koom Tes, txhim kho lub zog thiab tawv ntawm lub hom phiaj. Qhov hluav taws kub zoo yog ua kom sov cov hlau tsis xeb hlau fittings rau Ac3 lossis siab tshaj 30-50 ℃, thiab tom qab ib lub sijhawm ntawm kev rwb thaiv tsev, tshem tawm los ntawm lub cub tawg rau hauv huab cua lossis tshuaj tsuag dej, tshuaj tsuag lossis tshuab ua cua txias hlau kho txheej txheem. Lub hom phiaj yog ua kom cov lis txhim kho thiab cov carbide kev faib tawm homogenization. Qhov sib txawv ntawm qhov hluav taws kub zoo thiab kev sib koom tes yog qhov hluav taws kub cua txias sai dua li qhov ceev ceev annealing txias, yog li cov ntaub so ntswg li qub yog qis dua li cov ntaub so ntswg annealing, thiab nws cov khoom siv kho tshuab tseem muaj zog.


Tsis tas li ntawd, tsuas yog sab nraum lub qhov cub cua txias tsis nyob hauv cov khoom siv, qhov kev tsim khoom yog qhov siab, kom deb li deb tau siv hluav taws xob zoo nyob rau hauv kev tsim khoom siv ua tsis muaj kev cuam tshuam. Kev thov kom sib cuag yog txheej txheem kev kho cua sov hlau uas heats cov yeeb nkab steel hlau sai sai rau qhov ntsuas kub thiab tswj kom muaj qee lub sijhawm tom qab txias nrog qhov ceev uas tsim nyog.


Ib qho ntawm cov txheej txheem tseem ceeb tshaj plaws ntawm annealing yog qhov siab tshaj plaws cua kub cua sov, thiab xaiv cov annealing cua sov ntsuas kub ntawm feem ntau cov alloys yog ua raws tus qauv duab theem ntawm cov txheej txheem alloy no.


Quenching yog hais txog qhov cua sov ntawm lub raj hlau tsis txias mus rau qhov tseem ceeb kub ntawm Ac3 lossis Ac1 saum toj no qhov kub, tom qab lub sijhawm nyob ntawm qhov kev rwb thaiv tsev, kom tag nrho lossis ib feem ntawm nws cov austenite, thiab tom qab ntawd ntau dua li qhov tseem ceeb txias txias ntawm lub nrawm txias txias rau Ms hauv qab rau martensite kev hloov pauv ntawm cov txheej txheem kho cua sov. Tempering yog hais txog qhov quenching ntawm cov yeeb nkab steel hlau, hauv qab AC1 cua sov, rwb thaiv tsev tom qab txias txias ntawm cov khoom lag luam stainless hlau kub kho txheej txheem. Tempering kev kho yog qhov txheej txheem kho kub ntawm qhov kub thiab txias tom qab quenching.


Kev ntsuas qhov kub thiab txias yog hais txog qhov kub ntawm lub siab thaum 500-650 val luv.

Qhov kev hloov kho tuaj yeem hloov kho qhov ua tau zoo thiab cov khoom ntawm stainless hlau yeeb nkab kom zoo, kom lub zog, yas thiab tawv ntawm cov yeeb nkab muaj qhov ua haujlwm tau zoo, thiaj li ua tiav theem zoo ntawm cov cuab yeej txhua yam.
