Seamless Steel Yeeb Nkab Ua Li Cas

Seamless steel kav yog tsim los ntawm cov txheej txheem hu ua seamless yeeb nkab manufacturing, uas muaj cov kauj ruam hauv qab no:
Melting thiab Casting:
Cov txheej txheem pib nrog melting ntawm raw cov ntaub ntawv, feem ntau hlau ore, carbon steel, los yog tsawg alloy steel, nyob rau hauv lub cub tawg. Cov hlau molten yog tom qab ntawd nchuav rau hauv pwm los ua cov kab ntawv puag ncig lossis cov duab cylindrical.
Piercing:
Cov khoom billets yog rhuab mus rau qhov kub thiab txias thiab ces pierced ntawm qhov chaw uas siv ib tug tho zeb. Qhov no tsim ib tug hollow plhaub nrog ib tug ntxhib internal nto.
Kub Rolling:
Cov pierced billets yog ntxiv rhuab thiab dhau los ntawm ib tug series ntawm dov mills kom txo lawv txoj kab uas hla thiab phab ntsa thickness. Cov txheej txheem kub dov no elongates thiab tsim cov yeeb nkab.
Qhov loj me:
Cov yeeb nkab kub dov yog tom qab ntawd dhau los ntawm lub tshuab sizing kom ua tau raws li qhov xav tau qhov ntev thiab kam rau ua. Cov txheej txheem no ua kom zoo dua cov kab uas hla, phab ntsa thickness, thiab roundness ntawm cov yeeb nkab.
Cua txias:
Tom qab sizing, seamless yeeb nkab yog ceev ceev txias siv cua los yog dej kom stabilize nws cov qauv thiab txhua yam khoom.
Straightening:
Cov kav dej yuav dhau los ua cov txheej txheem ncaj los kho qhov khoov lossis deformations uas tshwm sim thaum lub sijhawm tsim khoom.
Txiav thiab Finishing:
Cov kav dej raug txiav mus rau qhov ntev uas yuav tsum tau ua thiab raug rau ntau yam txheej txheem tiav, xws li beveling, xaus threading, lossis txheej, nyob ntawm seb lawv xav siv.
Kev Tshawb Fawb thiab Kev Xeem:
Txhua cov yeeb nkab seamless tau soj ntsuam nruj thiab kuaj kom ntseeg tau tias nws ua tau raws li cov qauv kev ua tau zoo thiab kev ua tau zoo. Qhov no yuav suav nrog kev tshuaj xyuas qhov muag, kev kuaj xyuas qhov ntev, kev sim tsis muaj kev puas tsuaj (piv txwv li, ultrasonic lossis magnetic particle kuaj), thiab kev sim tshuab (xws li, tensile lossis hardness testing).
Marking thiab ntim:
Cov kav dej feem ntau yog cim nrog cov ntaub ntawv tseem ceeb, xws li qhov loj me, qib khoom siv, cov chaw tsim khoom lub npe, thiab cov xov tooj cua sov. Tom qab ntawd lawv tau ntim rau kev khaws cia lossis kev thauj mus los.
Seamless steel kav tau paub txog lawv qhov sib xws, lub zog, thiab muaj peev xwm tiv taus kev kub siab thiab kev siv kub. Vim tias lawv tsis muaj cov welded seam pom nyob rau hauv cov kav dej welded, cov kav dej seamless tsis tshua muaj kev cuam tshuam thiab feem ntau nyiam rau kev siv tseem ceeb hauv kev lag luam xws li roj thiab roj, petrochemicals, thiab hluav taws xob tsim hluav taws xob. Cov txheej txheem tsim seamless ua kom cov khoom zoo ib yam thiab txhim khu kev qha uas tuaj yeem ua tau raws li cov qauv kev lag luam nruj.
