Stainless hlau seamless yeeb nkab yog ib qho ntev sawb ntawm cov hlau nrog lub hollow cross - ntu thiab tsis muaj nqaws ib puag ncig nws.
1. Kev tsim qauv thiab ua haujlwm ntawm Seamless Steel Kav:
Smelting>Ingot>Rolling>Sawing>Peeling>Perforation>Annealing>Acid Cleaning>Ash Coating>Cold Drawing>Cutting Head>Acid Cleaning>Chaw ntim khoom
2. Cov yam ntxwv ntawm Seamless Steel Kav:
Los ntawm cov txheej txheem saum toj no, nws tsis yog qhov nyuaj kom pom tias: Firstly, cov tuab dua kev lag luam tuab ntawm cov khoom, cov kev coj ua yooj yim thiab nws cov nqi ntau dua; Thib ob, cov txheej txheem ntawm cov khoom txiav txim nws cov kev txwv. Feem ntau, seamless steel kav muaj tsawg daim ntawv tuab: cov chaw tsis sib xws ntawm cov yeeb nkab, thiab nyuaj rau tshem tawm pockarks, thiab cov pob dub nyob sab hauv thiab sab nraud; Thib peb, nws cov kev kuaj pom thiab kev sib sau yuav tsum ua cov txheej txheem offline. Yog li ntawd, nws ua rau pom nws zoo dua hauv kev kub siab, muaj zog, thiab cov khoom siv neeg kho tshuab cov khoom siv.
3, Welded Steel Yeeb Nkab
Welded steel yeeb nkab, sau cov yeeb nkab luv, yog cov hlau stainless hlau ua los ntawm vuam hlau phaj los yog cov hlau sib tsoo tom qab tau tsim los ntawm lub tshuab thiab pwm.

2. Cov yam ntxwv ntawm Welded Hlau Kav:
Los ntawm cov txheej txheem saum toj no, nws tsis yog qhov nyuaj kom pom tias: Ua ntej, cov khoom lag luam tuab hauv chav tsev thiab cov khoom siv vuam, ua rau nws tsis muaj kev lag luam tsawg dua thiab siv tau. The thinner the wall thickness, the lower its input-output ratio will be; Thib ob, cov txheej txheem ntawm cov khoom txiav txim siab nws cov txiaj ntsig thiab qhov tsis zoo. Feem ntau, welded steel kav muaj cov siab tawv, muaj kev sib cav sib luag ntawm cov hlau sib tw (kev txiav txim siab sab nraud ntawm qib steel), thiab tuaj yeem kho tau rau txhua qhov ntev. Yog li ntawd, nws ua kom pom nws cov kev lag luam thiab kev ua kom zoo nkauj hauv qhov siab- precision, nruab nrab cov ntawv thov siab muag.
Muaj chloride ions nyob rau hauv ib puag ncig kev siv. Chloride ions tau dav tam sim no, xws li ntsev, hws stains, seawater, hiav txwv, hiav txwv, av, thiab lwm yam. Stainless hlau corrodes sai nyob rau hauv muaj ntawm chloride ions, txawm tshaj tawm cov qes qis- cov hlau. Yog li yuav tsum muaj rau kev siv ib puag ncig stainless hlau, thiab nws yuav tsum tau ua kom tsis tu ncua kom tshem cov hmoov av thiab tswj kev nyiam huv thiab ua kom huv.
316 thiab 317 stainless hlau (saib cov khoom ntawm 317 stainless hlau hauv qab) yog molybdenum muaj hom stainless hlau. Cov ntsiab lus Molybdenum hauv 317 stainless hlau yog siab me dua li tias hauv 316 stainless hlau nyob rau hauv cov hlau, nws tag nrho cov kev ua tau zoo dua rau 310 thiab 304 stainless hlau. Nyob rau hauv cov kev mob siab ntau, 316 stainless hlau muaj ntau yam ntawm sulfuric corrosion, yog li nws yog siv nyob rau hauv cov av marine. Nrog rau kev txhim kho ntawm kev lag luam kev lag luam, daim ntawv thov ntawm stainless hlau kav tau dhau los ua ntau zuj zus. Nws yuav undenedly coj txog kev hloov tshiab hauv ntau thaj teb.
