DIN2391 Cold drawn Seamless Steel yeeb nkab thiab raj

Cold drawn steel tube yog nrog kub dov steel coil li raw khoom, thiab tandem txias dov pickled kom tshem tawm oxide nplai, nws tiav dov nyuaj yob, dov nyuaj ntim vim qhov nruam txias deformation tshwm sim los ntawm txias hardening zog, hardness nce qhov taw qhia tsis kam. tawv yas, stamping kev ua tau zoo yuav deteriorate, uas tsuas yog siv tau yooj yim deformation ntawm qhov chaw.

Cold Drawn Seamless Mechanical Tubing

Rolling nyuaj yob yuav siv tau raws li raw khoom ntawm kub-dip galvanizing cog, kub dip galvanizing kab teem annealing kab. Rolling nyuaj yob hnyav yog feem ntau 6 mus rau 13.5 tons, lub coil txoj kab uas hla ntawm 610mm.

Cov xwm txheej ntawm kev xa khoom:

Lub sij hawm	Cim	Kev piav qhia
Txias-tiav/ nyuaj (Cold-finished as-drawn)	BK	Tsis muaj kev kho cua sov tom qab lub txheej txheem txias txias kawg. Yog li ntawd, cov hlab ntsha tsuas muaj tsawg deformability.
Txias-tiav/ mos (mob ua haujlwm txias)	BKW	Tom qab kev kho cua sov kawg muaj lub teeb ci tiav (kev kos duab txias) Nrog rau kev ua tiav tom qab, lub raj tuaj yeem ua kom txias (xws li khoov, nthuav dav) hauv qee qhov kev txwv.
Annealed	GBK	Tom qab cov txheej txheem txias txias kawg, cov hlab yog annealed nyob rau hauv ib qho chaw tswj los yog nyob rau hauv lub nqus tsev vacuum.
Li qub	NBK	Cov hlab yog annealed saum toj ntawm qhov hloov pauv sab saud hauv qhov chaw tswj hwm lossis hauv qab lub tshuab nqus tsev.
