1. Kev qhia luv luv txog cov yeeb nkab qauv

Cov yeeb nkab tsis muaj qhov txuas rau cov qauv (GB/T8162-2008) yog siv rau cov qauv dav dav thiab cov qauv kho tshuab ntawm cov yeeb nkab tsis muaj qhov txuas. Cov yeeb nkab tsis muaj qhov txuas tau muab faib ua ntau yam kev siv sib txawv.

Cov yeeb nkab tsis xeb hlau tsis muaj qhov txuas rau cov qauv (GB / T14975-2002) yog cov yeeb nkab kub-dov (extruded, nthuav dav) thiab txias-kos (dov) seamless ua los ntawm cov hlau tsis xeb siv hauv tshuaj lom neeg, roj av, textile, kev kho mob, khoom noj, tshuab thiab lwm yam lag luam, cov yeeb nkab tiv taus corrosion thiab cov khoom siv thiab cov khoom.

GB/T8162-2008 (seamless yeeb nkab rau cov qauv) yog siv rau cov qauv dav dav thiab cov qauv kho tshuab. Nws cov khoom sawv cev (hom): carbon hlau 20, 45 hlau, Q235, hlau alloy Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo, 42CrMo thiab lwm yam.

Cov yeeb nkab hlau tsis muaj qhov txuas

Vim nws cov txheej txheem tsim khoom txawv, nws muab faib ua cov yeeb nkab hlau kub dov (extruded) seamless thiab cov yeeb nkab hlau txias rub (dov) seamless ob hom. Cov yeeb nkab txias rub (dov) muab faib ua cov yeeb nkab voj voog thiab cov yeeb nkab zoo li tshwj xeeb ob hom.

A. Kev txheeb xyuas ntawm cov txheej txheem ntws

Kub dov (extruded seamless steel tube): lub raj kheej kheej kheej → cua sov → perforation → peb-yob hla dov, txuas ntxiv dov lossis extrusion → raj stripping → sizing (lossis txo) → txias → raj dawb paug → ncaj → kev sim siab dej (lossis kev kuaj pom qhov tsis zoo) → cim → khaws cia.

Kev kos duab txias (dov) cov yeeb nkab hlau tsis muaj qhov tsis sib xws: lub raj kheej kheej kheej kheej → cua sov → perforation → heading → annealing → pickling → oiling (tooj liab plating) → ntau-pass txias kos duab (txias dov) → lub raj dawb paug → kev kho cua sov → ncaj → kev sim siab dej (qhov tsis zoo nrhiav) → cim → cia.
