Seamless steel yeeb nkab yog ib hom yeeb nkab uas tau tsim los ntawm cov khoom siv hlau, uas yog cua sov thiab tho. Cov txheej txheem no yog hu ua kub dov thiab nws tsim cov yeeb nkab seamless yam tsis muaj seams lossis welds.
Kev ua haujlwm ntawm cov yeeb nkab seamless muaj ob peb kauj ruam.
Billet npaj. Cov khoom billet yog soj ntsuam thiab rhuab mus rau qhov kub thiab txias. 1200 degree rau carbon steel pas nrig.
Piercing: lub rhuab billet yog pierced nrog ib tug mandrel los tsim ib tug hollow raj.
Rolling: lub rhuab billet yog dov mus rau hauv daim ntawv los tsim nws mus rau hauv ib tug seamless yeeb nkab.
Sizing: cov yeeb nkab txuas ntxiv dov thiab ncab mus rau qhov ua tiav qhov xav tau loj thiab tuab.
Kev kho cua sov: cov yeeb nkab yuav dhau los ua cov txheej txheem kho cua sov xws li annealing lossis quenching los txhim kho nws cov khoom siv kho tshuab.
Hom seamless yeeb nkab li bellowing.
Carbon steel seamless yeeb nkab. Cov yeeb nkab no yog tsim los ntawm cov pa roj carbon steel, cov kav dej no tau siv dav hauv ntau yam kev siv xws li kev thauj mus los roj thiab roj, kev txhawb nqa cov qauv, thiab cov kav dej dav dav.
Alloy steel seamless yeeb nkab. Cov yeeb nkab no yog tsim los ntawm cov hlau alloy, uas muaj cov ntsiab lus ntxiv xws li chromium, manganese, lossis npib tsib xee. Lawv yog siv nyob rau hauv daim ntawv thov uas yuav tsum tau siab zog, corrosion kuj, thiab kub kuj.
Stainless hlau seamless yeeb nkab. Cov yeeb nkab no ua los ntawm stainless hlau. Cov kav dej no muaj zog tiv taus corrosion thiab siv rau hauv cov ntawv thov kev nyiam huv thiab kev ua haujlwm ntev yog qhov tseem ceeb, xws li hauv kev lag luam khoom noj thiab khoom siv kho mob.
