Raws li hnub so dhau los, peb tau rov 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 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 nce ntxiv tsis ntev los no. Txhawm rau kom ntseeg tau tias peb tuaj yeem muab cov khoom lag luam zoo thiab cov kev pabcuam txuas ntxiv, cov nqi ntawm qee qhov kev txiav txim yuav tsum tau hloov kho.
Yog li ntawd, peb thov kom koj ua tib zoo saib xyuas cov teeb meem hauv qab no thaum muab xaj:
1. Kev sib txuas lus raws sij hawm: Yog tias koj muaj ib qho kev txiav txim uas tab tom sib tham lossis tab tom yuav muab tso, thov hu rau peb pab neeg kom sai li sai tau kom paub meej cov ntaub ntawv nqi tshiab.
2. Kev hloov kho tus nqi: Vim kev lag luam hloov pauv, tus nqi ntawm qee qhov kev txiav txim yuav hloov. 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. Transparency thiab kev txhawb nqa: Peb tau cog lus los tswj kom pom tseeb ntawm kev hloov kho tus nqi thiab muab cov lus piav qhia ntxaws txog kev hloov pauv ntawm tus nqi. Yog tias koj muaj lus nug lossis xav paub ntxiv, thov hu rau peb.
Seamless steel yeeb nkab yog cov yeeb nkab steel tsis muaj welds, uas yog siv dav hauv ntau yam kev lag luam. Nws cov yam ntxwv tseem ceeb yog lub zog siab muaj peev xwm, zoo corrosion kuj, thiab siab dabtsi yog khoov lub zog, yog li nws ua tau zoo nyob rau hauv ib puag ncig tshwj xeeb xws li kev kub siab thiab kub tsis kam. Cov txheej txheem ntawm cov kav dej seamless steel tau muab faib ua ob peb kauj ruam tseem ceeb, thiab kev tswj xyuas nruj nruj yog nqa tawm los ntawm kev ua cov khoom siv raw mus rau cov khoom kawg.
Cov txheej txheem ntau lawm
Kev tsim cov seamless steel kav pib nrog round steel billets. Round steel billets yog rhuab mus txog 1200 ℃ nyob rau hauv ib lub qhov cub cua sov thiab nkag mus rau cov txheej txheem kub dov. Cov txheej txheem kub dov siv lub tshuab tho los txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm Cov kauj ruam no txiav txim siab qhov pib zoo ntawm cov yeeb nkab steel thiab ua kom lub zog ntawm cov yeeb nkab steel.
Tom ntej no, lub pierced tube billet yog ntxiv nthuav thiab tsim los ntawm cov txheej txheem dov. Qhov kub, siab thiab ceev thaum lub sij hawm dov txheej txheem yuav tsum tau tswj xyuas kom meej qhov loj, phab ntsa thickness uniformity thiab nto zoo ntawm cov yeeb nkab steel.
Tom qab tsim, cov yeeb nkab steel yuav tsum tau mus los ntawm kev ua kom txias thiab ncaj. Kev ua kom txias yog kom sai txo cov yeeb nkab los ntawm qhov kub thiab txias mus rau chav sov kom ntseeg tau tias kev ruaj ntseg ntawm cov qauv metallographic ntawm cov khoom. Straightening yog tshem tawm cov dabtsi yog khoov los yog lwm yam deformation uas yuav tshwm sim thaum lub sij hawm tsim khoom thiab xyuas kom meej qhov ncaj ntawm cov yeeb nkab.
Thaum kawg, cov yeeb nkab steel kuj yuav tsum tau ua kom nruj nruj thiab ua tiav. Cov kev ntsuam xyuas no suav nrog kev kuaj xyuas qhov tsis zoo ntawm ultrasonic, eddy tam sim no nrhiav tau, thiab lwm yam, feem ntau yog kom ntseeg tau tias tsis muaj qhov tsis xws luag hauv cov yeeb nkab steel seamless thiab ua tau raws li cov qauv siv. Qee cov kav dej seamless steel tseem yuav raug kho cov txheej txheem xws li pickling thiab phosphating los txhim kho lawv cov corrosion kuj.
Kev ceev faj rau kev siv seamless steel kav
Raws li cov khoom siv muaj zog, siab-resistant thiab corrosion-resistant, seamless steel kav yog dav siv nyob rau hauv cov roj av, tshuaj, hluav taws xob, machinery thiab lwm yam lag luam. Txawm li cas los xij, txawm tias nws qhov kev ua tau zoo tshaj plaws, kev siv kom raug thiab kev saib xyuas yog qhov tseem ceeb los xyuas kom meej tias nws txoj haujlwm ruaj khov mus ntev hauv qhov chaw ua haujlwm. Cov hauv qab no yog kev ceev faj rau seamless steel kav thaum siv:
1. Xaiv cov khoom tsim nyog thiab cov lus qhia tshwj xeeb
Seamless steel kav muaj nyob rau hauv ntau yam ntaub ntawv thiab specifications. Thaum siv lawv, koj yuav tsum xaiv cov khoom tsim nyog raws li kev thov tshwj xeeb scenario. Cov kev ua haujlwm sib txawv (xws li kev ua haujlwm siab, qhov kub thiab txias, corrosiveness ntawm qhov nruab nrab, thiab lwm yam) muaj cov kev xav tau sib txawv rau cov khoom siv seamless steel kav. Piv txwv li, thaum thauj cov xov xwm kub kub, cov kav dej kub-resistant steel yuav tsum tau siv; nyob rau hauv ib puag ncig corrosive heev, seamless steel kav ua los ntawm stainless hlau los yog lwm yam corrosion-resistant cov ntaub ntawv yuav tsum tau siv. Yog li ntawd, ua ntej kev yuav khoom, koj yuav tsum ua kom nkag siab txog cov kev tsis zoo thiab siv cov xwm txheej ntawm cov yeeb nkab steel kom tsis txhob muaj kev nyab xeeb los ntawm kev xaiv cov khoom siv tsis raug.
2. Ua tib zoo saib rau txoj kev sib txuas ntawm cov kav dej thaum lub sijhawm teeb tsa
Txij li cov kav hlau tsis muaj seamless tsis muaj welds, lawv cov qauv kev ntseeg tau zoo dua, tab sis txoj kev sib txuas yuav tsum tsim nyog thaum lub sijhawm teeb tsa. Cov kev sib txuas feem ntau suav nrog flange kev sib txuas, xov txuas thiab vuam. Rau lub sijhawm kub siab thiab kub siab, vuam yuav tsum tau ceev faj tshwj xeeb, thiab qhov zoo ntawm cov vuam ncaj qha cuam tshuam rau kev pabcuam lub neej ntawm cov kav dej. Yog li ntawd, thaum lub sij hawm tsim kho, nws raug nquahu kom cov kws tshaj lij ua haujlwm kom ntseeg tau tias cov vuam tsis sib xws, tsis muaj qhov hws thiab tawg.
3. Kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua
Txawm hais tias cov kav dej seamless steel muaj kev tiv thaiv corrosion thiab ua haujlwm ntev, lawv tseem yuav tsum tau kuaj xyuas thiab tswj xyuas tsis tu ncua thaum siv, tshwj xeeb tshaj yog nyob rau hauv kev kub siab, kub kub los yog corrosive ib puag ncig. Cov kav dej tau raug rau lub sijhawm ua haujlwm ntev thiab kev yaig nruab nrab, thiab cov kab nrib pleb me me lossis cov ntsiab lus corrosion yuav tshwm sim. Kev ntsuam xyuas ultrasonic li niaj zaus, ntsuas kev sim thiab xeb kev sim siab tuaj yeem pab txhawm rau txhawm rau pom cov khoom zais hauv lub sijhawm thiab zam dhau kev sib raug zoo.
4. Tsis txhob siv ntau dhau
Seamless steel kav muaj lawv tsim siab tshaj plaws kev coj tus kheej muaj peev xwm thiab siab tshaj plaws ua haujlwm kub. Thaum siv, cov qauv tsim thiab cov kev cai yuav tsum tau ua kom tsis txhob muaj kev siv ntau dhau. Kev kub siab thiab kev siv overtemperature yuav ua rau deformation ntawm cov yeeb nkab, txo lub zog, thiab txawm tias rupture los yog to. Yog li ntawd, cov neeg ua haujlwm yuav tsum nruj me ntsis saib xyuas kev ua haujlwm siab thiab kub ntawm cov kav dej kom ntseeg tau tias nws ua haujlwm nyob rau hauv qhov chaw nyab xeeb.
5. Tiv thaiv kev puas tsuaj rau sab nraud
Thaum lub sij hawm kev thauj mus los, tuav thiab kev teeb tsa, seamless steel kav yuav raug cuam tshuam rau sab nraud thiab kev sib txhuam, uas yuav ua rau muaj kev puas tsuaj rau saum npoo thiab txawm cuam tshuam lawv lub zog tag nrho. Yog li ntawd, thaum tuav thiab khaws cia, kev tiv thaiv yuav tsum tau siv kom tsis txhob muaj kev sib cuag nrog cov khoom ntse, thiab tsis txhob rub cov yeeb nkab steel ntawm qhov siab, tshwj xeeb tshaj yog thaum cov yeeb nkab phab ntsa nyias.
6. Tiv thaiv sab hauv nruab nrab los ntawm kev scaling los yog clogging
Thaum siv mus sij hawm ntev, qhov nruab nrab hauv cov raj xa dej tuaj yeem tso rau hauv txheej txheej, tshwj xeeb tshaj yog thaum xa dej, chav dej lossis lwm yam xov xwm uas ua rau scaling. Scaling rau sab hauv phab ntsa ntawm lub raj xa dej yuav ua rau muaj kev tiv thaiv sab hauv ntawm lub raj xa dej, txo cov kev xa tawm, thiab txawm tias ua rau muaj kev cuam tshuam. Yog li ntawd, nws raug nquahu kom ntxuav nws tsis tu ncua thiab siv cov tshuaj ntxuav kom huv rau descaling thaum tsim nyog.
