1. Cov txheej txheem txheej txheem:
Vim hais tias ntawm cov kav hlau alloy 'kev tsim cov txheej txheem sib txawv, lawv tau muab faib ua kub dov (extrusion) seamless thiab txias rub (dov) Seamless ob.Cold drawn (dov) yeeb nkab yog muab faib ua cov yeeb nkab thiab cov yeeb nkab zoo li tus.
2. 15CrMo alloy tube Txheej txheem cej luam:
a.dov (extrusion seamless): ro und raj perforation → cua sov → peb-yob dov, dov los yog extrusion → detached → sizing (los yog txo) → txias → billet raj → straightening → hydrostatic test (los yog kuaj) → cim → cia.b.txias drawn (dov) seamless steel yeeb nkab: round perforated raj → cua sov → annealing → pickling → taub hau oiled (tooj liab) → multi-pass txias drawn (dov) → tshav kub kho → straightening yeeb nkab billet ncaj → hydrostatic test (testing) → cim → cia.
15CrMo alloy yeeb nkab yog ib hom seamless steel yeeb nkab, thiab nws cov kev ua tau zoo ntau dua li qhov nruab nrab ntawm seamless steel raj, vim cov hlau muaj Cr ntau hauv.Nws tuaj yeem dais qhov kub thiab txias, thiab corrosion yog zoo dua li lwm yam seamless kav kev ua tau zoo, yog li alloy tube yog dav dav hauv cov roj av, tshuaj, hluav taws xob, boiler thiab lwm yam lag luam.Competitive Advantage · Peb tuaj yeem muab cov kav dej tshwj xeeb raws li cov neeg siv khoom thov.· Peb kuj yog cov chaw tsim khoom, yog li peb tuaj yeem muab cov khoom lag luam raws li koj cov kev xav tau sai.· Peb lub tuam txhab muaj kev nplua nuj kev quab yuam thiab cov khoom siv ntau lawm thiab kev sib koom ua ke cov cuab yeej siv thiab cov txheej txheem.
