Thaum ntsib kev txiav txim uas yuav tsum tau tsim tawm, nws yog feem ntau tsim nyog yuav tsum tau lees tias yog cov qhua tuaj noj mov kom ob tog tuaj yeem pom zoo.

Cov txheej txheem ntau lawm ntawm seamless steel kav feem ntau yog suav nrog cov kauj ruam hauv qab no:

1. Billet npaj
Cov ntaub ntawv raw ntawm Seamless Steel kav yog cov kauj ruam hlau lossis kev cuam tshuam, feem ntau zoo carbon steel lossis cov hlau tsis muaj hlau. Lub billet yog ntxuav, nws cov nto yog kuaj xyuas qhov tsis xws luag, thiab txiav mus rau qhov ntev yuav tsum tau ua.

2. Cua sov
Lub billet tau xa mus rau cov cua sov cua sov kom muaj cua sov, feem ntau nyob rau cua sov ntawm txog 1200 ℃. Cov cua kub no yuav tsum muaj kev ua kom muaj txiaj ntsig thaum lub sijhawm ua cua sov kom cov txheej txheem perforational tom qab tuaj yeem ua kom yooj yim.

3. Perforation
Lub based rhu yog perforated los ntawm perforator los ua ib lub raj hollow. Cov kev siv perforation zoo ib txwm yog "oblique dov perforation", uas siv ob txoj kev sib hloov ob tog thaum tig mus rau pem hauv ntej thaum tig mus rau nws, yog li ntawd qhov chaw yog hollow.

4. Rolling (ncab)
Perforated ntxhib yeeb nkab yog ncab thiab qhov loj me los ntawm ntau yam khoom siv. Muaj feem ntau ob txoj kev:

Nruam cov qauv rolling: Siv ntau-kis Rolling Mill rau maj kom maj mam muab cov yeeb nkab txuas thiab txo cov phab ntsa tuab.

Yeeb Nkab Ua Nkaus Txoj Kev: Siv ib lub Mandrel los pab txhim kho thiab dov thiab siv lub diam uas hla ntawm cov yeeb nkab steel.

5. Sizing thiab txo
Txhawm rau kom ua tiav qhov yuav tsum tau ua kom zoo, cov ntaub xo tiag yog ua tiav hauv lub pob zeb sizing lossis txo zeb. Los ntawm kev khawb txuas ntxiv thiab ncab, sab nraud ntawm txoj hlua thiab phab ntsa tuab ntawm cov yeeb nkab raug hloov kho.

6. Kev kho cua sov
Txhawm rau txhim kho cov khoom siv tshuab ntawm cov yeeb nkab steel thiab tshem tawm sab hauv kev ntxhov siab, cov txheej txheem kev kho cua sov feem ntau xws li ib txwm muaj, tempering, quenching. Cov kauj ruam no tuaj yeem txhim kho cov tawv thiab ruaj khov ntawm cov yeeb nkab steel.

7. Ncaj thiab txiav
Cov yeeb nkab steel tom qab kev kho cua sov yuav bent thiab xav tau kom ncaj qha los ntawm ib tug ncaj. Tom qab ua kom ncaj, cov yeeb nkab steel tau txiav rau qhov ntev yuav tsum tau los ntawm cov qhua tuaj noj mov.

8. Kev Soj Ntsuam
Seamless steel kav yuav tsum tau yauv nruj nruj ua tau zoo kev tshuaj xyuas, uas feem ntau suav nrog cov hauv qab no:

Cov tsos tshuaj tshuaj xyuas: Tshawb xyuas seb puas muaj cov kab nrib pleb, tsis xws luag, thiab lwm yam nyob rau saum npoo ntawm cov yeeb nkab steel.
Kev soj ntsuam dimension: ntsuas seb txoj kab uas hla, phab ntsa thickness thiab ntev ntawm cov hlau yeeb ua kom tiav.
Tshuaj Tiv Thaiv Lub Cev: xws li Tensile Xeem, Cuam Tshuam, Hardness Kuaj, thiab lwm yam.
Tsis yog-kev sim ua txhaum: Siv ultrasound lossis xoo hluav taws xob txhawm rau paub seb puas muaj cov kab nrib pleb lossis pores sab hauv.
9. Ntim thiab xa khoom
Tom qab dhau mus kuaj, cov yeeb nkab steel yog kho nrog kev kho xeb thiab tiv thaiv xeb xeb raws li yuav tsum tau ua, thiab ntim khoom thiab xa khoom.

Los ntawm cov kauj ruam saum toj no, lub seamless steel kav tsim tawm yog siv dav hauv cov roj, tshuaj, boiler, boiler, corrosion tsis kam thiab cov kws kho zoo.
