Thaum lub caij so tas lawm, peb tau rov qab ua haujlwm li qub. Ua tsaug rau koj txoj kev txhawb nqa thiab kev nkag siab thaum lub caij so. Tam sim no, peb tos ntsoov yuav txuas ntxiv muab cov kev pabcuam zoo thiab zoo rau koj.
Raws li qhov xwm txheej ntawm kev ua lag luam hloov pauv, peb tau pom tias cov nqi tau txuas ntxiv nce siab tsis ntev los no. Yuav kom ntseeg tau tias peb tuaj yeem txuas ntxiv muab cov khoom lag luam thiab cov kev pabcuam zoo, cov nqi ntawm qee qhov kev txiav txim yuav tsum tau hloov kho.
Yog li ntawd, peb thov kom koj ua tib zoo mloog cov hauv qab no thaum tso cov xaj:
1. Kev sib txuas lus raws sijhawm: Yog tias koj muaj ib qho kev txiav txim uas tab tom sib tham lossis yuav raug tso, thov hu rau peb pab neeg sai li sai tau kom paub meej cov ntaub ntawv nqi tshiab.
2. Kev hloov tus nqi: Vim yog kev hloov pauv ntawm kev ua lag luam, tus nqi ntawm qee qhov kev txiav txim yuav hloov pauv. Peb yuav sim peb qhov zoo tshaj plaws kom tus nqi tsim nyog thiab kho nws raws sijhawm raws li qhov xwm txheej tshwj xeeb.
3. Kev Pom Tseeb thiab Kev Txhawb Nqa: Peb cog lus tias yuav ua kom pom tseeb hauv kev hloov tus nqi thiab muab cov lus piav qhia ntxaws txog kev hloov tus nqi. Yog tias koj muaj lus nug lossis xav tau cov ntaub ntawv ntxiv, thov hu rau peb.
Cov yeeb nkab hlau tsis muaj qhov sib txuas yog cov yeeb nkab hlau uas tsis muaj vuam, uas siv dav hauv ntau qhov chaw lag luam. Nws cov yam ntxwv tseem ceeb yog lub peev xwm dais siab, tiv taus corrosion zoo, thiab lub zog khoov siab, yog li nws ua tau zoo hauv cov chaw tshwj xeeb xws li kev kub siab thiab tiv taus kub. Cov txheej txheem tsim cov yeeb nkab hlau tsis muaj qhov sib txuas tau muab faib ua ntau kauj ruam tseem ceeb, thiab kev tswj xyuas zoo nruj heev tau ua tiav los ntawm kev ua cov khoom siv raw mus rau cov khoom kawg.
Cov txheej txheem ntau lawm
Kev tsim cov yeeb nkab hlau tsis muaj qhov tsis sib xws pib nrog cov hlau puag ncig. Cov hlau puag ncig raug cua sov txog li 1200 ℃ hauv lub cub tawg thiab nkag mus rau hauv cov txheej txheem dov kub. Cov txheej txheem dov kub siv lub tshuab tho qhov hlau billets kom tsim ib lub raj billet nrog lub qhov hauv nruab nrab. Cov kauj ruam no txiav txim siab qhov pib ntawm cov yeeb nkab hlau thiab xyuas kom meej tias cov qauv ntawm cov yeeb nkab hlau muaj zog.
Tom ntej no, lub raj xa dej uas raug tho qhov yuav nthuav dav ntxiv thiab tsim los ntawm cov txheej txheem dov. Qhov kub, siab thiab qhov ceev thaum lub sijhawm dov yuav tsum tau tswj kom meej kom ntseeg tau tias qhov loj me, phab ntsa tuab sib npaug thiab qhov zoo ntawm cov yeeb nkab hlau.
Tom qab ua tiav lawm, cov yeeb nkab hlau yuav tsum tau txias thiab ncaj. Kev txias yog kom txo cov yeeb nkab sai sai los ntawm qhov kub siab mus rau qhov kub hauv chav kom ntseeg tau tias cov qauv metallographic ntawm cov khoom ruaj khov. Kev ncaj yog kom tshem tawm qhov khoov lossis lwm yam kev hloov pauv uas yuav tshwm sim thaum lub sijhawm tsim khoom thiab xyuas kom meej tias cov yeeb nkab ncaj.
Thaum kawg, cov yeeb nkab hlau kuj yuav tsum tau kuaj thiab ua tiav nruj heev. Cov kev xeem no suav nrog kev kuaj xyuas qhov tsis zoo ntawm ultrasonic, kev kuaj xyuas tam sim no eddy, thiab lwm yam, feem ntau yog kom ntseeg tau tias tsis muaj qhov tsis zoo hauv cov yeeb nkab hlau seamless thiab ua tau raws li cov qauv siv. Qee cov yeeb nkab hlau seamless kuj tseem yuav dhau los ntawm cov txheej txheem kho qhov chaw xws li pickling thiab phosphating los txhim kho lawv txoj kev tiv thaiv corrosion.
Cov kev ceev faj rau kev siv cov kav hlau tsis muaj seamless
Ua ib yam khoom siv uas muaj zog heev, tiv taus siab thiab tiv taus xeb, cov kav hlau tsis muaj qhov sib txuas tau siv dav hauv roj av, tshuaj lom neeg, hluav taws xob, tshuab thiab lwm yam lag luam. Txawm li cas los xij, txawm tias nws ua tau zoo heev los xij, kev siv thiab kev saib xyuas kom raug tseem ceeb heev kom ntseeg tau tias nws ua haujlwm ruaj khov mus sij hawm ntev hauv qhov chaw ua haujlwm. Cov hauv qab no yog cov lus ceeb toom rau cov kav hlau tsis muaj qhov sib txuas thaum siv:
1. Xaiv cov ntaub ntawv thiab cov lus qhia tsim nyog
Cov yeeb nkab hlau tsis muaj qhov sib txuas muaj ntau yam khoom siv thiab cov lus qhia tshwj xeeb. Thaum siv lawv, koj yuav tsum xaiv cov khoom tsim nyog raws li qhov xwm txheej ntawm daim ntawv thov tshwj xeeb. Cov xwm txheej ua haujlwm sib txawv (xws li kev ua haujlwm siab, kub, kev xeb ntawm cov khoom nruab nrab, thiab lwm yam) muaj cov kev cai sib txawv rau cov khoom siv ntawm cov yeeb nkab hlau tsis muaj qhov sib txuas. Piv txwv li, thaum thauj cov khoom nruab nrab kub siab, yuav tsum siv cov yeeb nkab hlau uas tiv taus cua sov; nyob rau hauv ib puag ncig corrosive heev, yuav tsum siv cov yeeb nkab hlau tsis muaj qhov sib txuas ua los ntawm cov hlau tsis xeb lossis lwm yam khoom siv tiv taus xeb. Yog li ntawd, ua ntej yuav khoom, koj yuav tsum xyuas kom meej tias nkag siab txog cov kev cai thiab kev siv cov xwm txheej ntawm cov yeeb nkab hlau kom tsis txhob muaj kev phom sij rau kev nyab xeeb los ntawm kev xaiv cov khoom siv tsis raug.
2. Ua tib zoo saib xyuas txoj kev sib txuas ntawm cov kav dej thaum lub sijhawm teeb tsa
Vim tias cov kav hlau tsis muaj qhov vuam, lawv cov qauv zoo dua, tab sis txoj kev sib txuas yuav tsum tsim nyog thaum lub sijhawm teeb tsa. Cov txheej txheem sib txuas feem ntau suav nrog kev sib txuas flange, kev sib txuas threaded thiab kev vuam. Rau qhov siab thiab kub siab, kev vuam yuav tsum tau ceev faj tshwj xeeb, thiab qhov zoo ntawm qhov vuam cuam tshuam ncaj qha rau lub neej ua haujlwm ntawm cov kav dej. Yog li ntawd, thaum lub sijhawm tsim kho, nws raug pom zoo kom cov kws tshaj lij ua haujlwm kom ntseeg tau tias qhov vuam yog sib xws, tsis muaj qhov hws thiab tawg.
3. Kev tshuaj xyuas thiab kev txij nkawm tsis tu ncua
Txawm hais tias cov kav hlau tsis muaj qhov tsis sib xws muaj kev tiv thaiv corrosion siab thiab ruaj khov, lawv tseem yuav tsum tau kuaj xyuas thiab tswj xyuas tsis tu ncua thaum siv, tshwj xeeb tshaj yog nyob rau hauv qhov siab siab, kub siab lossis qhov chaw corrosive heev. Cov kav dej raug rau lub sijhawm ua haujlwm ntev thiab qhov nruab nrab erosion, thiab cov kab nrib pleb me me lossis cov ntsiab lus corrosion yuav tshwm sim. Kev kuaj ultrasonic tsis tu ncua, kev kuaj siab thiab kev kuaj corrosion tuaj yeem pab nrhiav pom cov kev phom sij zais cia hauv lub sijhawm thiab zam kev raug mob loj.
4. Tsis txhob siv ntau dhau
Cov yeeb nkab hlau tsis muaj qhov sib txuas muaj lawv qhov tsim los rau qhov siab tshaj plaws thiab qhov kub tshaj plaws rau kev ua haujlwm. Thaum siv, yuav tsum ua raws li cov qauv thiab cov cai tsim nyog kom tsis txhob siv ntau dhau. Kev siv siab dhau thiab kub dhau yuav ua rau cov yeeb nkab puas, txo lub zog, thiab txawm tias tawg lossis xau. Yog li ntawd, cov neeg ua haujlwm yuav tsum saib xyuas qhov siab ua haujlwm thiab qhov kub ntawm cov yeeb nkab kom ntseeg tau tias nws ua haujlwm hauv qhov chaw nyab xeeb.
5. Tiv thaiv kev puas tsuaj sab nraud
Thaum lub sijhawm thauj mus los, kev tuav thiab kev teeb tsa, cov kav hlau tsis muaj seamless yuav raug kev cuam tshuam los ntawm sab nraud thiab kev sib txhuam, uas yuav ua rau puas tsuaj rau saum npoo thiab txawm tias cuam tshuam rau lawv lub zog tag nrho. Yog li ntawd, thaum tuav thiab khaws cia, yuav tsum siv cov kev ntsuas tiv thaiv kom tsis txhob kov cov khoom ntse, thiab tsis txhob rub cov kav hlau raws li qhov xav tau, tshwj xeeb tshaj yog thaum phab ntsa yeeb nkab nyias.
6. Tiv thaiv kom tsis txhob muaj cov khoom nruab nrab sab hauv los ntawm kev txhaws lossis txhaws
Thaum siv ntev, cov khoom nruab nrab hauv cov kav dej yuav tso ua ib txheej nplai, tshwj xeeb tshaj yog thaum xa dej, pa dej lossis lwm yam khoom nruab nrab uas yooj yim rau kev nplai. Kev nplai rau ntawm phab ntsa sab hauv ntawm cov kav dej yuav ua rau cov kav dej tsis kam sab hauv ntau ntxiv, txo qhov kev xa khoom zoo, thiab txawm tias ua rau txhaws. Yog li ntawd, nws raug pom zoo kom ntxuav nws tsis tu ncua thiab siv cov tshuaj ntxuav kom tshem tawm cov nplai thaum tsim nyog.
