Keeb kwm kev loj hlob ntawm cov yeeb nkab hlau tsis sib haum
Kev tsim cov yeeb nkab hlau tsis muaj qhov sib txuas muaj keeb kwm ze li ntawm 100 xyoo. Cov kwv tij German Mannesmann tau tsim thawj lub tshuab tho ob lub yob hla lub raj hauv xyoo 1885, thiab lub tshuab zeb yeeb nkab tsis tu ncua hauv xyoo 1891. Xyoo 1903, Swiss RC stiefel tau tsim lub tshuab zeb yeeb nkab tsis siv neeg (tseem hu ua lub tshuab zeb yeeb nkab saum toj kawg nkaus). Tom qab ntawd, ntau lub tshuab txuas ntxiv xws li lub tshuab zeb yeeb nkab txuas ntxiv thiab lub tshuab rub yeeb nkab tau tshwm sim, uas tau pib tsim kev lag luam yeeb nkab tsis muaj qhov sib txuas niaj hnub. Xyoo 1930, vim yog kev siv peb lub tshuab zeb dov yeeb nkab, extruder thiab lub tshuab zeb dov txias tsis tu ncua, ntau yam thiab zoo ntawm cov yeeb nkab hlau tau txhim kho. Xyoo 1960, vim yog kev txhim kho ntawm lub tshuab zeb yeeb nkab txuas ntxiv thiab kev tshwm sim ntawm peb lub yob tho, tshwj xeeb tshaj yog kev vam meej ntawm lub tshuab txo qhov nro thiab lub tshuab casting tsis tu ncua, kev ua haujlwm zoo dua thiab kev sib tw ntawm cov yeeb nkab tsis muaj qhov sib txuas thiab cov yeeb nkab vuam tau txhim kho. Xyoo 1970, cov yeeb nkab tsis muaj qhov sib txuas thiab cov yeeb nkab vuam tau khaws cia, thiab cov yeeb nkab hlau thoob ntiaj teb tau nce ntxiv ntawm tus nqi ntau dua 5% ib xyoos. Txij li xyoo 1953, Tuam Tshoj tau muab qhov tseem ceeb rau kev txhim kho kev lag luam yeeb nkab seamless, thiab tau pib tsim ib lub tshuab tsim khoom rau dov txhua yam yeeb nkab loj, nruab nrab thiab me. Feem ntau, cov yeeb nkab tooj liab kuj siv cov txheej txheem ntawm billet hla dov thiab tho.
Daim ntawv thov thiab kev faib tawm ntawm cov yeeb nkab hlau tsis sib haum
Daim Ntawv Thov:
Cov yeeb nkab hlau tsis muaj qhov tsis sib xws yog ib hom hlau seem kev lag luam, uas ua lub luag haujlwm tseem ceeb heev hauv kev lag luam hauv tebchaws. Nws yog siv dav hauv roj av, kev lag luam tshuaj lom neeg, boiler, chaw tsim hluav taws xob, nkoj, kev tsim tshuab, tsheb, aviation, aerospace, zog, geology, kev tsim kho, kev lag luam tub rog thiab lwm yam.
Kev faib tawm:
① Raws li cov duab ntawm seem: cov yeeb nkab voj voog thiab cov yeeb nkab tshwj xeeb.
② raws li cov khoom siv: cov yeeb nkab carbon, cov yeeb nkab hlau alloy, cov yeeb nkab hlau tsis xeb thiab cov yeeb nkab sib xyaw.
③ raws li hom kev sib txuas: cov yeeb nkab txuas threaded thiab cov yeeb nkab welded.
④ raws li hom kev tsim khoom: kub dov (extrusion, jacking thiab nthuav dav) yeeb nkab thiab txias dov (kos duab) yeeb nkab.
⑤ raws li lub hom phiaj: boiler yeeb nkab, roj qhov dej yeeb nkab, pipeline yeeb nkab, structural yeeb nkab thiab tshuaj chiv yeeb nkab.
Kev tsim cov thev naus laus zis ntawm cov yeeb nkab hlau tsis sib xws
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 tshuaj xyuas lub raj mis → cua sov lub raj mis → kev tho qhov → dov lub raj → rov ua kom sov lub raj nyoos → kev ntsuas qhov loj (txo) → kev kho cua sov → kev ncaj lub raj tiav lawm → kev ua tiav → kev tshuaj xyuas (tsis puas tsuaj, lub cev thiab tshuaj lom neeg, kev sim zaum kawg) → kev khaws cia.
② Cov txheej txheem tseem ceeb ntawm cov yeeb nkab hlau txias dov (kos) seamless
Kev npaj ua ntej → pickling thiab lubrication → dov txias (kos duab) → kev kho cua sov → ncaj → tiav → tshuaj xyuas.
Daim ntawv qhia txog cov txheej txheem ntau lawm ntawm cov yeeb nkab kub dov seamless yog raws li nram no:
