Seamless steel yeeb nkab 301 304

Seamless steel yeeb nkab yog cov khoom siv tubular ua los ntawm cov hlau tsis muaj welded seam. Nws yog tsim los ntawm cov txheej txheem uas yuav tsum tau tho ib qho khoom siv hlau los tsim lub plhaub hollow. Cov txheej txheem no ua kom muaj cov qauv txuas ntxiv thiab homogeneous thoob plaws hauv cov yeeb nkab lub cev. Qhov tsis muaj seam muab nws ntau qhov zoo ntawm cov kav dej welded, xws li lub zog siab dua thiab zoo dua rau kev siab.

Cov txheej txheem pib nrog cov khoom siv hlau puag ncig, uas yog rhuab mus rau qhov kub siab (feem ntau nyob ib ncig ntawm 1200 - 1300 degrees Celsius). Tom qab ntawd nws tau dhau los ntawm lub tshuab tho. Lub pob zeb piercing muaj ib tug conical zoo li tus piercing plug thiab rollers. Raws li lub billet tig thiab txav mus rau pem hauv ntej, lub ntsaws ntsaws rau hauv nruab nrab ntawm lub billet, tsim ib lub raj hollow. Piv txwv li, nyob rau hauv cov txheej txheem Mannesmann, lub billet yog pierced los ntawm ib tug rotating piercer thiab ces elongated nyob rau hauv cov kauj ruam tom ntej dov.Tom qab tho, lub raj txuas ntxiv dov los txo nws txoj kab uas hla thiab phab ntsa thickness mus rau qhov xav tau qhov ntev. Qhov no yog ua los ntawm ib tug series ntawm dov stands. Cov txheej txheem dov pab txhim kho cov khoom siv kho tshuab ntawm cov yeeb nkab, xws li nws lub zog tensile thiab hardness. Sizing mills yog siv los xyuas kom meej cov yeeb nkab ua tau raws li qhov yuav tsum tau muaj qhov ntev, xws li lub taub sab nraud thiab phab ntsa tuab tolerances.Vim qhov kev npaj siv cov yeeb nkab seamless steel, nws yuav raug kho cua sov. Cov txheej txheem kho cua sov zoo li quenching thiab tempering tuaj yeem txhim kho cov yeeb nkab lub zog thiab toughness. quenching yuav ua kom txias cov yeeb nkab los ntawm qhov kub thiab txias, thiab tempering yog cov txheej txheem rov ua dua tom qab los txo cov kev ntxhov siab sab hauv thiab txhim kho ductility.
