1. Taw qhia rau cov kav hlau tsis xeb
Seamless steel yeeb nkab yog puag ncig, xwmfab thiab duab plaub hlau nrog ntu hollow thiab tsis muaj pob qij txha nyob ib puag ncig. Seamless steel kav yog ua los ntawm cov hlau ingots lossis cov raj xa khoom los ntawm kev tawg thiab tom qab ntawd ua los ntawm kub dov, txias txias lossis txias txias. Seamless steel kav muaj ntu hollow thiab feem ntau yog siv ua cov kav xa dej. Piv nrog cov hlau khov xws li cov hlau hloov pauv, cov kav hlau muaj tib yam khoov thiab ua kom muaj zog thiab hnyav dua. Lawv yog cov hlau hla ntu kev lag luam thiab tau siv dav hauv kev tsim qauv. Qhov chaw thiab cov khoom siv kho tshuab, xws li steel scaffolding rau roj xyaum, thiab lwm yam.
2. Keeb kwm ntawm kev tsim cov yeeb nkab hlau tsis sib haum
Kev tsim cov kav hlau tsis muaj txheej txheem muaj keeb kwm ze li 100 xyoo. Cov kwv tij German Manismann tau xub xub tsim ob-yob hla-dov lub tshuab hauv xyoo 1885, thiab tau tsim lub raj xa tshuab ib ntus hauv xyoo 1891. Xyoo 1903, Swiss R Stiefel (RCStiefel) tau tsim lub tshuab raj tsis siv neeg (tseem hu ua lub taub hau) dov cav). Cov yeeb nkab tshuab), ntau lub tshuab txuas ntxiv xws li cov yeeb nkab txuas txuas tsis tu ncua thiab cov tshuab xa cov yeeb nkab tau tshwm sim yav tom ntej, thiab kev lag luam niaj hnub tsis xeb hlau yeeb nkab tau pib tsim. Xyoo 1930s, vim tau txais kev siv peb lub raj xa hluav taws xob zeb zeb, lub tshuab txuas hluav taws xob, thiab lub caij txias txias lub raj zeb zeb, qhov ntau thiab zoo ntawm cov kav hlau tau txhim kho. Xyoo 1960, vim yog kev txhim kho ntawm cov raj zeb txuas mus ntxiv, qhov tshwm sim ntawm peb lub tshuab tho pob zeb, tshwj xeeb tshaj yog kev ua tiav ntawm daim ntawv thov ntawm kev txo cov nro thiab cov nruam nrum billet, txhim kho kev tsim khoom ntau ntxiv thiab txhim kho lub peev xwm ntawm cov kav dej tsis sib haum. los sib tw nrog cov yeeb nkab txuas. Hauv xyoo 1970, cov kav dej tsis sib txuas thiab cov kav dej txuas tau mus ua tes, thiab lub ntiaj teb' cov yeeb nkab steel tsim tau nce ntxiv ntawm qhov ntau xyoo ntau dua 5%. Tom qab xyoo 1953, Tuam Tshoj tau txuas qhov tseem ceeb rau kev txhim kho kev lag luam tsis muaj hlau yeeb nkab, thiab tau pib tsim cov txheej txheem tsim rau dov ntau cov kav dej loj, nruab nrab thiab me me. Cov kav tooj liab feem ntau tseem siv cov khauj khaum khawb, raj xa, thiab txheej txheej txheej txheem.
3. Kev siv thiab kev faib tawm ntawm cov kav hlau tsis xeb
Lub Hom Phiaj:
Seamless steel yeeb nkab yog ib hom kev lag luam steel, uas muaj txoj haujlwm tseem ceeb hauv kev lag luam hauv tebchaws. Nws tau siv dav hauv roj av, tshuaj lom neeg kev lag luam, boilers, chaw siv hluav taws xob, nkoj, kev tsim khoom siv tshuab, tsheb, aviation, aerospace, lub zog, geology, kev tsim kho thiab kev lag luam tub rog, thiab lwm yam haujlwm.

4. Seamless steel yeeb nkab ntau lawm txheej txheem
Ain Cov txheej txheem tseem ceeb ntawm cov kub-kuav los tiag seamless steel yeeb nkab (txheej txheem tshuaj xyuas tseem ceeb):
Kev npaj thiab tshuaj xyuas raj raj → raj cua sov cua sov → perforation → raj dov → pov tseg raj rov ua kom sov → tsau (txo) txoj kab uas hla → kho cua sov → ua kom tiav lub raj ncaj → ua tiav → tshuaj xyuas (tsis puas tsuaj, lub cev thiab tshuaj lom neeg, lub rooj zaum soj ntsuam) → cia
AinMain cov txheej txheem ntawm cov kuav los tiag txias (kos) seamless steel yeeb nkab
Kev npaj dawb paug → khaws thiab lubrication → txias txias (teeb duab) treatment kho cua sov → ncaj → tiav → tshuaj xyuas
