Txoj kev tsim khoom
DIN 17175 St35.8 seamless steel kav yuav ua tau los ntawm kub dov, txias dov, kub nias, kub kos duab los yog txias kos duab.
Cov kav hlau hlau tuaj yeem smelted nyob rau hauv ib qho qhib hearth los yog hluav taws xob rauv raws li txoj kev oxygen tshuab, thiab tag nrho cov hlau yuav tsum tau cam khwb cia zoo li qub.
Kev Xa Khoom
Lub 17175 St35.8 Seamless Steel Tubes Yuav xa los ntawm kev kho cua sov kom haum.Kev kho cua sov muaj xws li:
- normalizing
- Kev tso tawm
- Tempering;los ntawm quenching kub, nws tsis txias, tab sis ces tempered
- Kho qhov loj los ntawm isothermal transformation method.
Kev ua haujlwm kub yog ua tau los ntawm 1100 txog 850 ° C, thiab qhov kub tuaj yeem txo mus rau 750 ° C thaum ua haujlwm.

Cov raj yuav tsum tau muab cov cua sov kho kom haum rau lawv qhov ntev.Kev kho cua sov hauv qab no yuav tsum tau siv, nyob ntawm seb hom hlau:
normalizing.
Subcritical annealing.
Hardening thiab tempering nrog isothermal transformation.
Hardening thiab tempering nrog tas li txias los ntawm hardening kub thiab tom qab tempering.
