Yuav ua li cas seamless hlwb hlwb tsim?

1. Qhia rau txog tus nplha tshuab hlau ua rau zoo li no

Tus nplha tshuab hlau ua rau zoo li no yog hom kab hlau uas muaj lub voj voos, kab hlau ceg peb sab los yog ceg plaub sab uas muaj qhov hluv hluv hauv ntim, thiab tsis muaj qhov khoov khoov. Tus nplha tshuab hlau ua rau zoo li no yog ua los ntawm kab hlau los yog tus tshuab hlau uas ua nrog los ua kab hlau tshiab, tom qab ntawd ua los ntawm kev ua kab hlau hnyav, kab hlau ntsuab los yog kab hlau ntsuab. Tus nplha tshuab hlau ua rau zoo li no muaj lub hauv kab hlau hluv hluv, siv ntau heev rau kev tiv thaiv cov ntsuab, kab hlau thiab kab hlau kab peb sab thiab lwm yam kab hlau uas tseem ceeb, nyob rau hauv kev ua kom zoo thiab ua kom txuas mus li, lub nplha hlau muaj qhov zoo li no muaj qhov zoo li no yog hom kab hlau uas muaj kev lag luam zoo heev, siv ntau heev rau kev tsim cov khoom siv thiab cov khoom siv ua rau siab, xws li cov kab hlau siv rau kev kho tshuab ntoo hlau thiab lwm yam.

2. Tus nplha tshuab hlau ua rau zoo li no lub sijhawm ntawm kev hloov pauv

Seamless steel yeeb nkab ntau lawm muaj keeb kwm ze li ntawm 100 xyoo. Cov kwv tij German Manisman thawj zaug tau tsim lub tshuab ob-siab skew thom khwm hauv xyoo 1885, thiab kev tsim lub caij nplooj ntoos hlav dov tshuab hauv xyoo 1891. Xyoo 1903, Swiss R.C.Stiefel tau tsim lub tshuab tsis siv neeg cov yeeb nkab dov tshuab (tseem hu ua cov yeeb nkab sab saum toj dov tshuab), thiab tom qab ntawd tau tshwm sim cov yeeb nkab txuas txuas ntxiv rau lwm lub tshuab, thiab tom qab ntawd tau tshwm sim cov yeeb nkab txuas txuas ntxiv rau lwm lub tshuab. seamless steel yeeb nkab kev lag luam. Hauv xyoo 1930, ntau yam zoo ntawm cov yeeb nkab steel tau txhim kho los ntawm kev siv peb-siab yeeb nkab dov tshuab, extruding tshuab thiab lub caij txias yeeb nkab dov tshuab. Nyob rau xyoo 1960, vim yog kev txhim kho ntawm cov yeeb nkab txuas txuas txuas ntxiv, qhov tshwm sim ntawm peb-yob perforator, tshwj xeeb tshaj yog daim ntawv thov ntawm nro txo tshuab thiab nruam casting billet ua tiav, txhim kho kev tsim khoom, txhim kho cov yeeb nkab seamless thiab welded yeeb nkab kev sib tw muaj peev xwm. Nyob rau hauv lub 70′s seamless yeeb nkab thiab welded yeeb nkab yog abreast, lub ntiaj teb no steel yeeb nkab tso zis ntawm tus nqi ntawm ntau tshaj 5% ib xyoos twg. Txij li thaum xyoo 1953, Tuam Tshoj tau txuas qhov tseem ceeb rau kev tsim cov yeeb nkab steel seamless kev lag luam, thiab tau pib tsim cov txheej txheem ntau lawm rau dov ntau yam loj, nruab nrab thiab me kav. Cov yeeb nkab tooj liab kuj tseem siv ingot cross - dov perforation, raj zeb dov, coil txheej txheem.

3. Siv thiab qauv ntawm cov ntim hlav ua ntim

Tus Tshiab:

Cov ntim hlav ua ntim yog qhov chaw ua lag luam hlav, muaj qhov chaw pib tseem ceeb hauv lub neej ntawm lub ntiaj teb, siv tshaj tawg hauv petroleum, kev lag luam tshuaj, thawv, lwm lub voj voog, tshuab nrov, kev lag luam tshwj xeeb, hlav hlau, aviation, av, kho vaj tse, kho mob, tshav ntiaj, geology, chaw ua vaj tse thiab kev lag luam tsev neeg thiab lwm yam.

Qauv:

(1) Txij li qhov qauv, nws txiav pov mus rau qhov chaw ua pov thiab qhov chaw ua pov

(2) Txij li cov nta raws li: cov ntim hlav carbon, cov ntim hlav alloy, cov ntim hlav stainless, cov ntim composite

(3) Txij li kev nyob: cov ntim muab taw, cov ntim ua taw

(4) Txij li kev tsim khoom: hot rolling (extrusion, top, expansion) pipe, cold rolling (drawing) pipe

(5) siv los ntawm: thawv hlav, hlav hlav, hlav hlav, hlav hlav, hlav hlav tshuaj...

4, kev tsim khoom hlav hlav hlav

① Kev tsim khoom tshwj xwm (kev saib xyuas tshwj xwm) ntawm cov neeg hlau hlau ua rau hauv ntaus:

Pov thawj kev prepare thiab kev saib xyuas → pov thawj kev hla → ua hlau hlau → tsim hlau hlau → hla dua pov thawj → kho (txo) lub kaum → kev hla → zoo siab hlau hlau → zoo qhov chaw → zoo nkhwv (tsis ua haujlwm, nram qab thiab saib xyuas ntawv) → khoov

② Cold rolled (drawing) kev tsim hlau hlau hlau tshwj xwm

Kev prepare pov thawj → hla thiab lub zog → hla ntxiv (drawing) → kev hla → zoo siab → zoo qhov chaw → zoo nkhwv → saib xyuas.
