Nyob rau hauv xyoo tas los no, lub koom haum tshawb fawb hlau thiab hlau ua ke nrog lub teb chaws kev lag luam kev tsim kho thiab lub teb chaws txoj haujlwm loj ntawm kev ua tau zoo ntawm cov yeeb nkab steel yeeb nkab tau ua tiav ntau yam kev ua tiav. Raws li nws cov lus qhia, nyob rau hauv pipeline steel, pipeline steel team ntawm lub koom haum ntawm cov hlau thiab hlau kev tshawb fawb tau pom qhov correlation ntawm qhov luaj li cas ntawm deformed austenite thiab kev ua tau zoo ntawm DWTT (poob rauj kua muag kuaj) los ntawm kev kawm ntawm cov khoom micro-structure. thiab toughening mechanism, nteg lub hauv paus theoretical rau kev daws qhov tawg toughness tswj teeb meem ntawm pipeline steel nrog siab zog thiab thickness specifications.Los ntawm kev tshawb fawb nyob rau hauv tag nrho cov txheej txheem lub koom haum refinement thiab homogenization tswj tshuab ntawm pipeline steel, lub zog, toughness thiab plasticity txuam tswj technology ntawm pipeline steel nrog siab zog thiab thickness specification tau tawg los ntawm lub tshiab tiam ntawm kev ua tau zoo pipeline ntau lawm tau yooj yim.
Raws li lub hauv paus no, lub koom haum tshawb fawb hlau thiab steel hlau alloy cov ntsiab lus thiab cov txheej txheem txheej txheem tau kawm txog kev cuam tshuam txoj cai ntawm kev ua haujlwm ntawm cov yeeb nkab steel, txiav txim siab qhov sib txawv ntawm cov yeeb nkab steel alloy tsim cov qauv thiab cov txheej txheem, thiab tsim kev koom tes nrog cov tseem ceeb hauv tsev. mills (super) tuab pipeline steel thiab lwm yam kev ua tau zoo pipeline steel khoom, stabilizing ntau lawm hauv batch. Nyob rau tib lub sijhawm, lub koom haum kev tshawb fawb ntawm cov hlau thiab hlau tau tsim cov yeeb nkab steel nrog ntau yam khoom tshwj xeeb, xws li cov kav dej sib sib zog nqus steel, cov kav dej kub tsis tshua muaj siab, loj deformation resistant pipeline steels, corrosion resistant pipeline steels, thiab lwm yam. los xyuas kom meej lub teb chaws pipeline kev tsim kho thiab lub zog ruaj ntseg. Tsis tas li ntawd, kub dov steel sawb ntawm nruam roj zoo yeeb nkab, nruam roj zoo yeeb nkab, galvanized steel yeeb nkab thiab lwm yam technologies ntau lawm. tau sim thiab siv.
Nyob rau hauv lub nam ntawm tuag steel, H13 kub ua hauj lwm tuag steel tau thawj zaug tsim nyob rau hauv Tuam Tshoj, thiab kev sib xyaw thiab lub tshuab tshiab ntawm "siab purity smelting" tau tsim nws tus kheej. H13 steel nce mus txog qib NADCA (North American tuag casting koom haum) # 207 Superior zoo thawj zaug hauv Suav teb. Zhi-ling tian tau taw qhia tias lub koom haum tshawb fawb hlau thiab hlau nyob rau hauv domestic thawj zaug tsim kom tau raws li cov txheej txheem thoob ntiaj teb qib siab (NADCA # 207-2016) ntawm cov khoom zoo square steel yeeb nkab; Cov khoom lag luam zoo tau mus txog qib siab thoob ntiaj teb los rhuav tshem cov kev lag luam txawv teb chaws thiab ua tiav hauv lub tsheb gearbox plhaub pwm, topped 120000 thawj zaug hauv kev pab cuam lub neej hauv tsev (national advanced 100000 zaug).
