Cov Cai Xa Khoom
Nyob ntawm seb cov xwm txheej xa khoom thiab PSL theem, X60 tuaj yeem raug cais ua pawg raws li hauv qab no:
PSL1: x60 los yog L415;
PSL2: X60N, X60Q, X60M los yog L415N, L415Q, L415M.
N: Qhia txog kev ua kom cov khoom siv zoo li qub. Los ntawm kev ua kom cov hlau kub mus rau qhov kub thiab txias ua raws li cua txias. Txhawm rau txhim kho cov qauv me me thiab cov khoom siv kho tshuab ntawm cov hlau thiab kom nws cov tawv thiab sib xws.
Q: Sawv cev rau Quenching thiab Tempering. Tempering ntawm hlau los ntawm kev ua kom sov rau qee qhov kub, txias nws sai, thiab tom qab ntawd ua kom sov nws dua rau qhov kub qis dua. Txhawm rau kom tau txais qhov sib npaug ntawm cov khoom siv kho tshuab tshwj xeeb, xws li lub zog siab thiab kev tawv.
M: Qhia txog kev kho cua sov thiab tshuab. Kev sib xyaw ua ke ntawm kev kho cua sov thiab kev siv tshuab los ua kom zoo dua qhov microstructure thiab cov khoom ntawm hlau. Nws muaj peev xwm ua kom lub zog thiab kev tawv ntawm hlau thaum tswj cov khoom vuam zoo.

Yog tias koj pom cov lus luv luv no nyuaj rau nkag siab, mus saib peb cov ntawv sau ua ke ntawmCov lus luv luv rau cov kav hlau.
Cov txiaj ntsig ntawm SAWL (LSAW)
Yog tias koj xav tau cov yeeb nkab hlau loj thiab tuab, qhov kev xaiv thib ib yogSAWL (LSAW) cov yeeb nkab hlau. Cov yeeb nkab hlau LSAW tuaj yeem tsim tau ntau qhov loj txog li 1500 hli hauv txoj kab uas hla thiab 80 hli hauv phab ntsa tuab, uas muaj peev xwm ua tau raws li qhov xav tau ntawm cov kav dej ntev rau cov haujlwm loj.
Tsis tas li ntawd xwb, thaum lub sijhawm tsim khoom, LSAW cov yeeb nkab hlau siv ob sab submerged arc vuam (DSAW) txheej txheem, uas ua kom ntseeg tau qhov zoo ntawm cov xov hlau.
API 5L X60 Cov Tshuaj Lom Zem
PSL1 yooj yim dua li PSL2 hais txog cov tshuaj lom neeg sib xyaw, cov khoom siv kho tshuab, thiab lwm yam uas yuav tsum tau ua.
Qhov no yog vimPSL1sawv cev rau qib tus qauv zoo rau cov yeeb nkab hlau, thaumPSL2tuaj yeem pom tau tias yog qhov hloov kho dua tshiab ntawm PSL1, uas muaj cov lus qhia tshwj xeeb ntau dua thiab kev tswj hwm zoo dua.
