Hauv kev ua haujlwm ntawm kev ua hlau, cov xee hlau yog cov cuab yeej tseem ceeb ua, thiab nws txoj kev muaj pes tsawg leeg yog qhov tseem ceeb heev. Cov menyuam steel yog tsuas yog tsim los ntawm cov menyuam lub cev, ncej thiab xaus phaj. Txhua feem yuav tsum tau ua tiav meej thiab nruj me ntsis tswj kom ntseeg tau tias tag nrho cov kev ua tau zoo ntawm cov hlau.
Ua ntej tshaj plaws, cov menyuam lub cev feem ntau yog ua los ntawm seamless steel yeeb nkab, uas ua kom cov khaub ncaws sib txawv thiab lub zog ntawm cov menyuam lub cev. Tus ncej feem ntau yog ua los ntawm 45 puag ncig hlau kom tau raws li cov kabmob ntawm cov kabmob thiab kev sib hloov. Lub phaj kawg yog ua los ntawm Q235 steel phaj, uas tsis tsuas yog bears lub siab los ntawm cov kabmob uas yog ua haujlwm ruaj khov ntawm cov steel menyuam.
Tom qab cov ntaub ntawv xaiv tiav lawm, nws yog qhov txuas zoo. Raws li daim duab loj, tshwj tseg kev ua haujlwm tsim nyog rau kev txiav. Hauv cov txheej txheem tig tom ntej, qhov sib txuam ntawm cov menyuam lub cev, kawg phaj thiab ncej tau ua tiav kom ua tiav qhov kev sib txuam uas yuav tsum tau ua qhov tseeb.
Lub vuam txuas yuav tsum tsis txhob tsis quav ntsej ib yam. Nyob rau theem no, txoj kev txhawb nqa tav nyob rau hauv cov menyuam lub cev, kev sib tw ntawm cov shofed ntawm ob qho tib si yuav tsum tau kho kom ua tau kev ua haujlwm ntawm cov hlau.
Tom qab ntawd, kev ntxhov siab sab hauv yog tshem tawm los ntawm annealing los ntawm cov menyuam yaus tau tig mus rau qhov kev tswj hwm uas yuav tsum tau ua rau cov menyuam ua haujlwm ntawm kev ua haujlwm roughness thiab radial runial runout kam. Hauv tshwj xeeb, qee cov qauv tshwj xeeb steel rollers yuav tsum tau plated nrog lub zog chrome txheej tom qab kev ua kom zoo thiab hnav tsis kam ntawm cov menyuam yaus.
Los ntawm cov txheej txheem ntawm cov kauj ruam ntau lawm, hlau cov menyuam yaus nrog kev ua tau zoo tshaj plaws yog yug los, lav kom muaj kev lees paub rau kev ua lag luam tom ntej.
