1. Kev Taw Qhia Txog Cov Yeeb Nkab Hlau Tsis Muaj Qhov Txuas
Cov yeeb nkab hlau tsis muaj seamless yog ib hom hlau puag ncig, plaub fab, thiab plaub fab uas muaj qhov khoob thiab tsis muaj qhov sib txuas ib puag ncig. Cov yeeb nkab hlau tsis muaj seamless yog ua los ntawm cov hlau ingot lossis cov raj khov kho uas muaj qhov perforated rau hauv cov raj wool, thiab tom qab ntawd ua los ntawm kev kub dov, txias dov lossis kos txias. Cov yeeb nkab hlau tsis muaj seamless muaj qhov khoob, ntau tus siv rau kev xa cov kav dej kua, cov yeeb nkab hlau thiab cov hlau puag ncig thiab lwm yam hlau khov kho, tib lub sijhawm muaj zog khoov thiab torsional, lub teeb yuag, yog ib hom hlau seem nyiaj txiag, siv dav hauv kev tsim cov khoom siv thiab cov khoom siv kho tshuab, xws li cov hlau scaffolding roj drilling.
2. Keeb kwm ntawm kev tsim cov yeeb nkab hlau tsis muaj seamless
Kev tsim cov yeeb nkab hlau tsis muaj seamless muaj keeb kwm ze li ntawm 100 xyoo. Cov kwv tij German Manisman tau tsim thawj lub tshuab tho ob-siab skew hauv xyoo 1885, thiab kev tsim lub tshuab dov yeeb nkab periodic hauv xyoo 1891. Xyoo 1903, Swiss RCStiefel tau tsim lub tshuab dov yeeb nkab tsis siv neeg (tseem hu ua lub tshuab dov yeeb nkab sab saum toj), thiab tom qab ntawd tau tshwm sim lub tshuab dov yeeb nkab tas mus li thiab lub tshuab thawb yeeb nkab thiab lwm yam tshuab txuas ntxiv, pib tsim kev lag luam yeeb nkab tsis muaj seamless niaj hnub. Xyoo 1930, qhov zoo ntawm ntau yam yeeb nkab hlau tau txhim kho los ntawm kev siv lub tshuab dov yeeb nkab peb-siab, tshuab extruding thiab tshuab dov yeeb nkab txias periodic. Xyoo 1960, vim muaj kev txhim kho ntawm lub tshuab dov yeeb nkab tas mus li, qhov tshwm sim ntawm peb-yob perforator, tshwj xeeb tshaj yog kev siv lub tshuab txo qhov nro thiab kev ua tiav ntawm kev ua tiav ntawm cov khoom siv casting tas mus li, txhim kho kev ua haujlwm ntau lawm, txhim kho kev sib tw ntawm cov yeeb nkab tsis muaj seamless thiab cov yeeb nkab welded. Xyoo 1970, cov yeeb nkab tsis muaj seamless thiab cov yeeb nkab welded tau sib tw, cov yeeb nkab hlau thoob ntiaj teb tau tsim tawm ntau dua 5% ib xyoos. Txij li xyoo 1953, Tuam Tshoj tau muab qhov tseem ceeb rau kev tsim cov yeeb nkab hlau tsis muaj seamless, thiab thaum xub thawj tau tsim ib lub tshuab tsim khoom rau dov ntau yam yeeb nkab loj, nruab nrab thiab me. Cov yeeb nkab tooj liab kuj tseem siv tau rau kev dov ingot hla perforation, raj zeb dov, thiab txheej txheem kos duab coil.
3. Siv thiab kev faib tawm ntawm cov yeeb nkab hlau tsis sib xws
Siv:
Cov yeeb nkab hlau tsis muaj qhov tsis sib xws yog ib hom hlau hla kev lag luam, muaj txoj haujlwm tseem ceeb heev hauv kev lag luam hauv tebchaws, siv dav hauv roj av, kev lag luam tshuaj lom neeg, boiler, chaw tsim hluav taws xob, nkoj, kev tsim khoom siv, tsheb, aviation, aerospace, zog, geology, kev tsim kho thiab tub rog thiab lwm yam.
Kev faib tawm:
(1) Raws li cov duab seem, nws muab faib ua cov yeeb nkab seem voj voog thiab cov yeeb nkab seem tshwj xeeb
(2) Raws li cov khoom siv: cov yeeb nkab carbon, cov yeeb nkab hlau alloy, cov yeeb nkab stainless hlau, cov yeeb nkab sib xyaw
(3) Raws li hom kev sib txuas: cov yeeb nkab txuas threaded, cov yeeb nkab welded
(4) Raws li txoj kev tsim khoom: kub dov (extrusion, sab saum toj, nthuav dav) yeeb nkab, txias dov (kos duab) yeeb nkab
(5) los ntawm kev siv: boiler yeeb nkab, roj qhov yeeb nkab, pipeline yeeb nkab, qauv yeeb nkab, tshuaj chiv yeeb nkab……
4, cov txheej txheem tsim cov yeeb nkab hlau tsis muaj seamless
① Cov txheej txheem tsim khoom tseem ceeb (txheej txheem tshuaj xyuas tseem ceeb) ntawm cov yeeb nkab hlau kub dov seamless:
Kev npaj thiab kev tshuaj xyuas lub raj xa dej → cua sov lub raj xa dej → qhov tho → dov lub raj → rov ua kom lub raj sov dua → kho (txo) txoj kab uas hla → kho cua sov → ncaj lub raj tiav lawm → ua tiav → kev tshuaj xyuas (tsis ua puas tsuaj, lub cev thiab tshuaj lom neeg, kev tshuaj xyuas rooj) → khaws cia
② Cov txheej txheem tseem ceeb ntawm cov yeeb nkab hlau tsis sib txuas (kos duab) txias dov
Kev npaj ua ntej → pickling lubrication → txias dov (kos duab) → kev kho cua sov → ncaj → tiav → tshuaj xyuas.
