12Cr1MoVG siab siab alloy steel yeeb nkab zoo kev ruaj ntseg

Vim muaj cov txheej txheem tsim khoom sib txawv, nws tau muab faib ua kub dov (extruded) seamless steel yeeb nkab thiab txias rub (dov) seamless steel yeeb nkab. Cold drawn (dov) yeeb nkab tau muab faib ua cov yeeb nkab thiab cov yeeb nkab tshwj xeeb.

ib. Txheej txheem kev khiav dej num

Kub dov (extruded) seamless steel yeeb nkab: round raj dawb paug → cua sov → perforation → peb yob cross dov, nruam dov los yog extrusion → yeeb nkab stripping → sizing (los yog txo) → txias → blank raj → straightening → hydrostatic test (los yog flaw detection) → npav → warehouse.

Cold drawn (dov) seamless steel yeeb nkab: round tube dawb paug → cua sov → perforation → taub hau → annealing → pickling → oiling (tooj liab plating) → multi pass txias drawing (txias dov) → blank raj → tshav kub kho → straightening → hydrostatic test (qhov tsis zoo nrhiav) → npav → warehousing.
