Cov txheej txheem ntau lawm ntawm rebar yog qhov txheej txheem ua ke thiab ua rau muaj ntau kauj ruam los xyuas kom meej thiab ua tau zoo ntawm cov khoom kawg. Ua ntej, kev tsim khoom pib nrog kev xaiv ntawm cov khoom siv raw, feem ntau yog cov hlau zoo. Cov ntaub ntawv raw no yog smelted, rhuab mus rau siab kub thiab melted rau hauv cov kua hlau. Tom ntej no, cov kua dej ua kua tau nchuav rau hauv ib nruam casting tshuab lossis pouring tshuab los ua thawj zaug hlau billet los ntawm pwm. Cov pob nyiaj no yog ces txias thiab dov los tsim cov hlau sib txawv ntawm txawv diameters thiab cov duab.
Thaum lub sij hawm tsim cov rebar, yuav siv tau, xws li kub dov, raug mob lossis kos duab txias, kom ua tiav lub cev xav tau. Piv txwv li, dog dig Carbon Steel Kub-Rolled Roll Hlau Rods nrog ib txoj kab uas hla los ntawm ib qho tsis siv neeg ncaj thiab txias kos duab thiab ncaj. Rau txoj kab uas loj dua hlau hlau tuav, lawv yuav tsum tau txuas los ntawm vuam ua ntej kos duab lossis txiav ncaj qha. Kev txiav ntawm cov hlau tuav feem ntau ua tiav siv hluav taws xob lossis kev tuav cov hlau bar tej tshuab.
Qhov khoov ntawm cov hlau hlau yog lwm kauj ruam tseem ceeb, uas ua kom ntseeg tau tias cov hlau tuav tuaj yeem khoov tau raws li cov qauv tsim qauv. Qhov no feem ntau yog ua rau ntawm lub tshuab dabtsi yog khoov, thiab rau cov hlua dab tsi, thiab cov kab me me me me ceg, nws yuav ua rau ntawm ntau lub tshuab khoom siv ntau lub tshuab lossis sib sau ua ke tshuab. Vuam ntawm cov tuav kuj tseem yog ib feem ntawm cov txheej txheem ntau lawm, suav nrog cov txheej txheem xws li chaw vuam thiab muaj zog ntawm kev sib txuas.
Hauv kev ua cov pob txha taub hau hlau thiab cov hlau nplaum hlau, cov tsim cov khoom tuav tau sib xyaw ua ke rau hauv cov qauv tsim nyog. Qhov no feem ntau yog ua los ntawm kev tuav khi, arc vuam thiab chaw vuam. Tshwj xeeb tshaj yog nyob rau hauv prestressed qhob vaj tse cov qauv, kev ua cov hlau prestressed yog ib qho tseem ceeb, thiab lawv yuav tsum tau mus dhau los ntawm cov txheej txheem tshwj xeeb.
