Seamless steel kav yuav muab faib ua carbon structural steel, low alloy structural steel, thiab alloy structural steel. Feem ntau siv cov ntaub ntawv muaj xws li kub dov seamless steel kav, txias dov seamless steel kav, thiab txias-draw seamless steel kav. Lawv feem ntau yog kho cua sov seamless steel kav. , kev kho cua sov ntawm cov kav dej txias-dov seamless steel kav yog qhov nyuaj dua li cov kav dej kub-dov seamless steel kav. Kub-dov seamless steel kav yog tsim los txuas ntxiv ntawm cov kab ntau lawm. Cold-dov seamless steel kav thiab txias-draw seamless steel kav tsis tas yuav tsim, thiab txias-dov seamless steel kav tsis tas yuav tsim. Qhov saum npoo zoo thiab qhov tseeb qhov tseeb ntawm cov yeeb nkab seamless steel yog zoo dua li cov kav hlau kub-dov.
Cold-dov hlau yog cov hlau tsis muaj carbon. Vim nws cov ntsiab lus carbon tsawg thiab zoo plasticity, nws tuaj yeem ua tau txias-kuav los tiag. Nyob rau hauv cov nqe lus ntawm kev ua tau zoo, qhov zoo ntawm cov ntaub ntawv txias-kuav los tiag yog zoo dua li cov ntawv kub-dov hlau vim oxide nplai yuav raug tsim tawm ntawm cov hlau thaum kub dov. Rolling yog nqa tawm saum toj no lub recrystallization kub ntawm cov khoom siv hlau, thaum txias dov yog hais txog dov hauv qab ntawm recrystallization kub ntawm cov khoom hlau. Txhua cov khoom siv hlau muaj nws tus kheej recrystallization kub.
Kub dov txhais tau hais tias cov khoom yuav tsum tau rhuab thaum lub sij hawm los yog ua ntej steel dov txheej txheem, feem ntau mus rau recrystallization kub.
Txias dov txhais tau hais tias cov txheej txheem steel dov tsis tas yuav tsum tau cua sov ntawm cov khoom, los yog nws yog rhuab mus rau recrystallization kub ntawm cov khoom.
Kub-dov seamless steel yeeb nkab khoom yog qhov yooj yim ntxhib. Nyob rau hauv cov nqe lus ntawm ntau lawm technology, kub-dov seamless steel kav thiab txias-dov seamless steel kav yog ua tiav nyob rau hauv high kub thiab yuav tsis hloov cov yam ntxwv ntawm cov hlau. Cold-drawn seamless steel kav tsis muaj. .
Nyob rau hauv cov nqe lus ntawm kev siv, qhov kom zoo dua ntawm txias-dov seamless steel yeeb nkab yog ua kom puas lub casting qauv ntawm cov hlau ingot thiab tshem tawm cov tsis xws luag nyob rau hauv lub microstructure, yog li ua rau cov steel qauv ntom thiab txhim kho cov neeg kho tshuab zog.
Qhov tsis zoo ntawm cov kav dej kub-dov seamless steel kav yog tias tom qab kub dov, cov hlau suav nrog hauv cov hlau raug nias rau hauv cov ntawv nyias thiab delamination tshwm sim, uas ua rau kev ua haujlwm tsis zoo thiab muaj peev xwm tsim kua muag. Cov cua txias tsis sib xws ua rau muaj kev ntxhov siab, uas tuaj yeem ua rau muaj teeb meem loj xws li deformation, stability, thiab qaug zog tiv thaiv. Ntxiv mus, nws yog ib qho nyuaj rau tswj lub thickness thiab ntug ntawm kub-kuav los tiag steel khoom. Yuav muaj qhov txawv tsis zoo ntawm qhov ntev thiab tuab ntawm cov hlau. Yog li ntawd, tsis muaj txoj hauv kev los tswj cov ntug, thickness, ntev, lub kaum sab xis, thiab ntug ntawm cov hlau.
