Kev txhim kho ntawm stainless hlau yeeb nkab fittings:
Ua ntej, Tuam Tshoj cov hlau ntau lawm feem ntau yog siv cov txheej txheem qub-fashioned blast-kuav converter, thiab cov khoom siv hluav taws xob rau cov hlau tsuas yog 15% ntawm tag nrho cov khoom tsim tawm ntawm cov hlau tsis huv. Txhawm rau txhim kho lub zog ntawm cov hlau thiab hlau ntau lawm thiab tshem tawm cov fetters ntawm coking thee peev txheej rau kev tsim cov hlau thiab hlau, kev txhim kho ntawm cov hlau txo qis yog ib txoj hauv kev tseem ceeb.
Qhov thib ob, kev kho dua tshiab ntawm cov khoom lag luam stainless hlau lub luj tshib thiab kev hloov kho ntawm cov qauv khoom xav tau cov khoom siv hlau hlau, thiab cov hlau txo ncaj qha yog ib qho tseem ceeb raw khoom rau kev tsim cov hlau zoo heev thiab net steel.
Thib peb, cov cuab yeej tsim khoom lag luam yog qhov xav tau ceev nrooj ntawm cov hlau zoo hlau casting thiab forging blanks, thiab tsis muaj kev tsim khoom thiab muab cov hlau zoo hlau casting thiab forging blanks yog ib qho tseem ceeb cuam tshuam rau kev loj hlob sai ntawm Tuam Tshoj cov khoom tsim kev lag luam. Txoj kev loj hlob ntawm kev txo cov hlau ncaj qha, siv ncaj qha txo cov hlau ua cov khoom siv los tsim cov hlau zoo hlau casting thiab forging blanks, yuav txhawb txoj kev loj hlob ntawm Tuam Tshoj cov khoom tsim kev lag luam.
Txoj kev loj hlob ntawm kev txo cov hlau ncaj qha yog ib txoj hauv kev tseem ceeb kom ua tiav kev txuag hluav taws xob thiab kev txo qis hauv kev lag luam hlau thiab hlau.
Qhov tsis txaus ntawm cov khoom seem hlau yog qhov tseem ceeb cuam tshuam rau kev txhim kho ntawm Tuam Tshoj txoj kev lag luam hlau thiab hlau, txo kev siv hluav taws xob ib tuj ntawm cov hlau, thiab kho cov qauv ntawm cov khoom steel. Tuam Tshoj tus kheej tsim cov khoom seem tsis tuaj yeem ua tau raws li qhov xav tau ntawm cov hlau thiab hlau ntau lawm nyob rau lub sijhawm luv luv, cov khoom seem tsis yog tsuas yog kim, tab sis kuj nws qhov ntau thiab zoo yog qhov nyuaj rau kev ua kom tau raws li qhov xav tau ntau lawm. Tsim cov hlau txo qis ncaj qha thiab hloov cov khoom seem nrog cov hlau ncaj qha txo qis yog qhov zoo tshaj plaws los daws cov teeb meem ntawm cov khoom tsis txaus ntawm cov khoom seem hauv Suav teb.
Carbon steel luj tshib preheating yog qhov zoo los txo qhov kub ntawm qhov chaw ntawm cov hlau thiab tiv thaiv cov kab nrib pleb, uas yog cov txheej txheem tseem ceeb ntawm vuam carbon steel, preheating tuaj yeem txhim kho kev sib koom ua ke thiab txo cov kev ntxhov siab tom qab vuam. Feem ntau, lub preheating kub ntawm 35 thiab 45 steel yog 150 ~ 250 degree, thiab cov ntsiab lus carbon yog siab dua los yog lub thickness thiab nruj yog loj, thiab cov tawg nyiam yog loj, lub preheating kub yuav nce mus rau 250 ~ 400 degree. Yog tias qhov vuam loj dhau lawm thiab tag nrho cov preheating yog qhov nyuaj, lub hauv paus preheating tuaj yeem ua tau, thiab cov cua sov ntawm lub hauv paus preheating yog 150 ~ 200mm ntawm ob sab ntawm cov vuam sib txuas. Thaum cov txheej txheem electrode tso cai, qhov yooj yim electrode yog nyiam.
Yog tias kev tshem tawm kev ntxhov siab tsis tuaj yeem ua tom qab vuam, kev kho cua sov yuav tsum tau ua tam sim ntawd. Nyob rau hauv cov nqe lus ntawm tsim kev nyuaj siab ib leeg, lub siab tsis kam ntawm carbon steel luj tshib yog zoo dua. Txawm li cas los xij, vim muaj ntau yam, qhov tseeb phab ntsa tuab ntawm cov yeeb nkab cua sov hauv pem teb feem ntau yog txhua yam ntawm cov kav dej hauv cov phab ntsa tuab no tuaj yeem ua tau raws li cov kev xav tau ntawm cov cua sov hauv pem teb, thiab qhov zoo ntawm lub teb chaws tus qauv carbon steel luj tshib yeeb nkab tsis tuaj yeem cuam tshuam. ; Thermal conductivity: Cov yeeb nkab uas siv rau hauv pem teb cua sov yuav tsum muaj cov thermal conductivity zoo, tsis kub kub poob siab tsis kam mus rau qhov kub tsis tshua muaj kev ua haujlwm. Cov pa roj carbon steel yuav tsum tau ceev faj nyob rau hauv cov txheej txheem vuam, siv nyob rau hauv qhov tsim nyog ib puag ncig, tas li ua tiav cov khoom tseem ceeb, vuam hauv qhov chaw tseem ceeb, thiab txiav txim siab zoo. Groove form Qhib qhov vuam rau hauv U-shaped zawj hom kom deb li deb tau rau vuam. Yog hais tias nws yog ib qho tsis xws luag, cov duab ntawm qhov zawj khawb tawm los ntawm rab chais yuav tsum du, thiab lub hom phiaj yog txo qhov kev faib ua feem ntawm lub hauv paus hlau rau hauv cov hlau weld kom txo tau cov ntsiab lus carbon nyob rau hauv weld thiab tiv thaiv cov kab nrib pleb.
