Kauv faus arc raj dov raj txoj kev yog thawj yob molding txoj kev
Thaum lub sij hawm ntawm lub ntim sab sauv, hauv qab ntawm cov yeeb nkab steel ntawm ntau yam kev qhia tshwj xeeb tsis hloov pauv, yog li cov cuab yeej siv tau yooj yim dua thiab yooj yim rau kev tsim khoom, thiab qhov nyiaj ntawm civil engineering kuj yog me me. Thaum lub sij hawm yob, lub taub hau vuam sab hauv yog nyob ze ntawm qhov nkag ntawm cov qhab, thiab nws tuaj yeem yooj yim los hloov cov khoom xws li conductivity. Nws tsis yog qhov tsim nyog los txiav qhov ntawm cov yeeb nkab steel, uas tuaj yeem txuag cov hlau thiab txuag lub sijhawm.
Vuam ntawm qhov taw tes occlusion yog yooj yim rau cov thev naus laus zis siab los tswj cov vuam khoob kom ntseeg tau tias vuam zoo. Tsis tas li ntawd, nws yog ib qho yooj yim rau tshem tawm cov hlau oxide ntawm daim tawv nqaij ntawm lub puab thiab sab nraud siab rollers, thiab nws yog ib qho yooj yim los hloov cov khoom seem. Yog li ntawd, feem ntau ntawm cov kab ntau lawm ntawm feem ntau muab kauv faus arc welded kav yog dav siv.
Tom qab xyoo 1980, txoj kev tsim ntawm dov tau pib tshem tawm.
Kev txheeb xyuas qhov ua rau ntawm qhov ua rau xoob, nruj thiab sab nrauv ntoo thuv lossis qhib qhov tsis xws luag thaum tsim cov seams nruj
(1) Qhov dav ntawm cov hlau ua haujlwm tsis sib xws lossis cov ntug ntawm cov hlau tsis zoo, uas yog ib qho yooj yim uas yuav ua rau cov tsim kom xoob kom nruj.
(2) Qhov siab ntawm vuam cushion roller tsis txaus, uas tuaj yeem yooj yim ua rau nruj thiab sab nraud loosening nyob rau hauv txoj kev seam.
(3) Lub ntug ntawm cov hlua hlau tsis muaj txoj kab nqes los yog muaj lub qhov ncauj nchuav (nrog rau qhov dav thiab nqaim ntawm cov hlau hauv qab), ua rau nruj nreem xoob thiab sab hauv xoob ntawm txoj hlua khi.
(4) Cov duab ntawm cov menyuam ntsug yog qhov tsis tsim nyog (feem ntau cov menyuam oblique yog siv rau ntawm qhov nkag ntawm lub molder), thiab siv txoj hlua khi nrog rau sab ntug ntawm cov hlau yuav ua rau sab hauv thiab sab nraud ntawm txoj hlua khi.
(5) Cov txheej txheem xaim hlau tsis zoo yog qhov tsis zoo, uas tuaj yeem yooj yim ua rau muaj qhov tshwm sim ntawm qhov nruj thiab cov xoob xoob sab hauv thiab sab hauv thiab sab nrauv thiab lub sijhawm xoob.
(6) Qhov qhib ntawm lub seam feem ntau yog tshwm sim los ntawm qhov tsis txaus deformed steel deformation, kev ua haujlwm ceev heev, lossis kev sib txuas sab hauv kev sib txuas ntev.
Kauv steel kav yog tsuas yog siv rau dej engineering engineering, petrochemical kev lag luam, tshuaj, hluav taws xob, ua liaj ua teb irrigation thiab kev tsim kho nroog. Siv rau kev thauj mus los ua kua: dej ntws. Natural gas kev thauj mus los: natural gas, steam, liquefied petroleum gas. Kev siv tus qauv: rau pawg raj thiab choj; rau cov docks, txoj kev, lub tsev, thiab lwm yam.
