Kev txhim kho keeb kwm ntawm seamless steel yeeb nkab
Seamless steel yeeb nkab ntau lawm muaj keeb kwm ze li ntawm 100 xyoo.Cov kwv tij German Mannesmann thawj zaug tau tsim ob lub yob hla rolling piercer nyob rau hauv 1885, thiab lub sij hawm cov yeeb nkab zeb nyob rau hauv 1891. Nyob rau hauv 1903, lub Swiss RC stiefel invented lub automatic yeeb nkab zeb (tseem hu ua lub saum toj kawg nkaus yeeb nkab zeb).Tom qab ntawd, ntau lub tshuab txuas ntxiv xws li cov yeeb nkab txuas txuas ntxiv thiab cov yeeb nkab jacking tshuab tau tshwm sim, uas tau pib tsim cov kev lag luam niaj hnub seamless steel yeeb nkab.Nyob rau xyoo 1930, vim yog siv peb cov yeeb nkab dov zeb, extruder thiab lub caij txias dov zeb, ntau yam thiab zoo ntawm cov kav hlau steel tau txhim kho.Nyob rau xyoo 1960, vim yog kev txhim kho ntawm cov yeeb nkab txuas txuas ntxiv thiab qhov tshwm sim ntawm peb yob piercer, tshwj xeeb tshaj yog kev vam meej ntawm kev nro txo zeb thiab nruam casting billet, kev tsim khoom tau zoo dua qub thiab kev sib tw ntawm seamless yeeb nkab thiab welded yeeb nkab tau txhim kho.Nyob rau xyoo 1970, cov yeeb nkab tsis muaj seamless thiab welded yeeb nkab tau ua kom nrawm, thiab lub ntiaj teb cov yeeb nkab tso tawm tau nce ntawm tus nqi ntau dua 5% ib xyoos.Txij li thaum xyoo 1953, Tuam Tshoj tau txuas qhov tseem ceeb rau txoj kev loj hlob ntawm seamless steel yeeb nkab kev lag luam, thiab tau pib tsim cov txheej txheem ntau lawm rau dov txhua yam loj, nruab nrab thiab me kav.Feem ntau, cov yeeb nkab tooj liab kuj tau txais cov txheej txheem ntawm billet cross dov thiab tho.
Daim ntawv thov thiab kev faib tawm ntawm seamless steel yeeb nkab
Daim ntawv thov:
Seamless steel yeeb nkab yog ib hom kev lag luam seem hlau, uas ua lub luag haujlwm tseem ceeb hauv kev lag luam hauv teb chaws.Nws yog dav siv hauv roj av, tshuaj lom neeg kev lag luam, boiler, fais fab chaw nres tsheb, nkoj, machinery manufacturing, tsheb, aviation, aerospace, zog, geology, kev tsim kho, tub rog kev lag luam thiab lwm yam departments.
Kev faib tawm:
① Raws li cov duab seem: lub voj voog ntu yeeb nkab thiab cov yeeb nkab tshwj xeeb.
② raws li cov khoom siv: carbon steel yeeb nkab, alloy steel yeeb nkab, stainless hlau yeeb nkab thiab cov yeeb nkab sib xyaw.
③ raws li hom kev sib txuas: threaded txuas yeeb nkab thiab welded yeeb nkab.
④ raws li hom ntau lawm: kub dov (extrusion, jacking thiab expansion) yeeb nkab thiab txias dov (kos duab) yeeb nkab.
⑤ raws li lub hom phiaj: boiler yeeb nkab, roj zoo yeeb nkab, cov yeeb nkab yeeb nkab, cov yeeb nkab thiab cov yeeb nkab yeeb nkab.
Kev tsim technology ntawm seamless steel yeeb nkab
① Cov txheej txheem tseem ceeb (kev tshuaj xyuas tseem ceeb) ntawm kub dov seamless steel yeeb nkab:
Tube dawb paug npaj thiab tshuaj xyuas → tube dawb paug cua sov → perforation → raj dov → reheating ntawm raw raj → sizing (txo) → tshav kub kho → straightening ntawm tiav lawm raj → xov → soj ntsuam (nondestructive, lub cev thiab tshuaj, lub rooj zaum kuaj) → warehousing.
② Cov txheej txheem tseem ceeb ntawm cov khaub thuas dov (kos) seamless steel yeeb nkab
Kev npaj dawb → pickling thiab lubrication → txias dov (kos duab) → kho cua sov → straightening → tiav → tshuaj xyuas.
Cov txheej txheem ntau lawm khiav daim ntawv ntawm kub dov seamless steel yeeb nkab yog raws li nram no:
