Lub seamless steel yeeb nkab yog ua los ntawm cov plaub hau plaub hau nrog ib tug hlau ingot los yog cov khoom tube, thiab ces ua los ntawm kub dov, txias dov los yog txias.
Lub seamless steel yeeb nkab muaj qhov hollow seem thiab ntau cov kav dej rau thauj cov kua dej.
Piv nrog cov khoom siv hlau xws li cov kav hlau thiab cov hlau puag ncig, thaum lub zog tiv thaiv kev sib tw thiab kev sib tw ntawm lub zog yog tib yam, qhov hnyav yog lub teeb. Nws yog ib qho kev lag luam steel hlau. Nws yog siv dav hauv kev tsim cov qauv thiab cov khoom siv kho tshuab, xws li steel scaffolding ntawm roj av pob zeb diamond.
Seamless steel yeeb nkab txoj kev loj hlob keeb kwm
Seamless steel yeeb nkab ntau lawm muaj keeb kwm ze li ntawm 100 xyoo.
Cov kwv tij Germans Mannman thawj zaug tau tsim lub tshuab oblique dov perforation hauv xyoo 1885. Xyoo 1891, lub voj voog dov tshuab tau tsim. Yeeb nkab tshuab), ntau yam ntawm cov tshuab txuas ntxiv xws li cov tshuab txuas txuas txuas ntxiv thiab cov tshuab yeeb nkab sab saum toj tau tshwm sim yav tom ntej, thiab pib tsim cov kev lag luam niaj hnub seamless steel yeeb nkab.
Hauv xyoo 1930, qhov zoo ntawm cov yeeb nkab steel tau zoo dua qub vim yog siv peb lub tshuab dov, tshuab extrusion, thiab cyclical txias dov yeeb nkab tshuab.
Vim yog kev txhim kho ntawm lub tshuab dov hauv xyoo 1960, qhov tshwm sim ntawm peb-cov menyuam tho tshuab, tshwj xeeb tshaj yog kev vam meej ntawm daim ntawv thov nruj, thiab kev ua tiav ntawm kev nruam casting.
Nyob rau xyoo 1970, cov kav dej seamless thiab welded kav tau tsav ua ke, thiab cov khoom tsim tawm ntawm cov kav hlau hauv ntiaj teb tau nce ntawm tus nqi ntau dua 5% hauv ib xyoos. Tom qab xyoo 1953, Tuam Tshoj txuas ntxiv qhov tseem ceeb rau txoj kev lag luam seamless steel yeeb nkab, thiab nws tau pib tsim cov txheej txheem ntau lawm rau dov ntau yam loj, nruab nrab thiab me kav.
Cov kav dej tooj liab feem ntau yog siv hauv ingots kab pheeb ces kaum dov, dov raj dov cav tov, thiab cov txheej txheem ncab.
Lub hom phiaj thiab kev faib tawm ntawm seamless steel kav
Siv: Seamless steel kav yog ib hom kev lag luam steel, uas muaj txoj haujlwm tseem ceeb hauv kev lag luam hauv lub tebchaws. Nws yog dav siv hauv roj av, tshuaj lom neeg kev lag luam, boilers, fais fab chaw nres tsheb, nkoj, machinery manufacturing, tsheb, aerospace, zog, geology, kev tsim kho thiab kev tsim kho thiab kev tsim kho thiab kev tsim kho thiab kev tsim kho thiab kev tsim kho thiab kev tsim kho thiab kev tsim kho thiab kev tsim kho thiab kev tsim kho thiab kev tsim kho. Tub rog kev lag luam thiab lwm yam departments.
Kev faib tawm:
① Raws li cov duab ntawm seem: voj voog seem raj, alien seem raj
② Raws li cov khoom siv: carbon steel yeeb nkab, alloy steel yeeb nkab, stainless hlau yeeb nkab, cov yeeb nkab sib xyaw
③ Muab faib los ntawm kev sib txuas: xov txuas txuas, vuam raj
④ Raws li txoj kev tsim khoom: kub dov (squeezing, top, expansion) raj, txias dov (rub) raj
⑤ Raws li kev siv: boiler raj, roj zoo yeeb nkab, pipeline raj, structural raj, tshuaj raj
